`src/` stands for *source*, and is the **raw code** before minification or concatenation or some other compilation - used to read/edit the code.

`dist/` stands for *distribution*, and is the **minified/concatenated** version - actually used on production sites.

This is a common task that is done for assets on the web to make them smaller.

Where should ajax request be made in Flux app?

I have started collaborating with a few friends on a project &amp; they use the heroku git repository.

I cloned the repository a few days ago and they have since made some changes so I am trying to get the latest updates

I ran the `git pull --rebase` command as stated here(Is this the right way to do it?): https://devcenter.heroku.com/articles/sharing#merging-code-changes

I get the following error:

    $ git pull --rebase
    Cannot pull with rebase: You have unstaged changes.
    Please commit or stash them.


My guess is that I messed around with the code and now it wants me to either commit or discard(is that what does stash means?) the changes. Is this what is happening? If this is the case I would like to discard any changes I might have made and just get the updated code from the git repository. 

Any idea of what I can do?

I&#39;m looking at a git repo for a jquery plugin. I want to make a few changes for use in my own project, but when I opened up the repo it had a structure I&#39;ve never seen before. I&#39;m not sure which files to use / copy into my own project.

There is a &quot;dist&quot; and a &quot;src&quot; folder. What purpose do these serve? Is this something specific for gruntjs or maybe jquery plugins?

I have a variable in PHP, and I need its value in my JavaScript code. How can I get my variable from PHP to JavaScript?

I have code that looks like this:
```php
&lt;?php
$val = $myService-&gt;getValue(); // Makes an API and database call
```

On the same page, I have JavaScript code that needs the value of the `$val` variable to be passed as a parameter:

```js
&lt;script&gt;
    myPlugin.start($val); // I tried this, but it didn&#39;t work
    &lt;?php myPlugin.start($val); ?&gt; // This didn&#39;t work either
    myPlugin.start(&lt;?=$val?&gt;); // This works sometimes, but sometimes it fails
&lt;/script&gt;
```

I have a little div tag that when I click on it (`onClick` event), it will run the `printMousePos()` function.

These are the `HTML` tags:

    &lt;html&gt;
        &lt;header&gt;
            &lt;!-- By the way, this is not the actual html file, just a generic example. --&gt;
            &lt;script src=&#39;game.js&#39;&gt;&lt;/script&gt;
        &lt;/header&gt;
        &lt;body&gt;
            &lt;div id=&quot;example&quot;&gt;
                &lt;p id=&quot;test&quot;&gt;x: , y:&lt;/p&gt;
            &lt;/div&gt;
        &lt;/body&gt;
    &lt;/html&gt;


This is the `printMousePos` function in a seperate .js file:

    function printMousePos() {
	    var cursorX;
	    var cursorY;
	    document.onmousemove = function(e){
		cursorX = e.pageX;
		cursorY = e.pageY;
	}
	    document.getElementById(&#39;test&#39;).innerHTML = &quot;x: &quot; + cursorX + &quot;, y: &quot; + cursorY;
    }

Yes, the function actually works (it knows when you click it and all), but it returns `undefined` for both `x` and `y`, so I&#39;m assuming that the getting `x` and `y` logic in the function is incorrect. Any Ideas? I also know there aren&#39;t any built-in functions within javascript itself to return the `x` and `y` like in java, ex. would there be a way to do it with say JQuery or PHP? (avoid those if possible though, javascript would be best). Thanks!

How can I set response header on express.js assets

To gain better understanding of how promises work in Javascript I decided to give it a try and code basic implementation myself. 

Basically I want to implement Promises Object (I call it Aaa in my code) that takes function as an argument. This function can call resolve to `resolve` the promise, or reject to `reject` it. The basic implementation and usage is below. Not sure if the second argument is accepteable according to promise specs, but that&#39;s what I got so far.


    Aaa=function(f,pause) { 
        
        console.log(&quot;ggg&quot;);
    
        var t=this;
        this.f=f;
        this.thens=[];
    
        this.resolve=function(g) {
         
            for(var i=0;i&lt;t.thens.length;i++)
            {
            	// try/catch to be used later for dealing with exceptions
    
                try
                {
                    t.thens[i].f(g);
                    t.thens[i].resolve();
                }   
                catch(ex)
                {}
    
            }
        };  
    
        // to be implemented later
        this.reject=function(g) {};
      
        this.then=function(resolve,reject) {
    
        	// i&#39;m passing true for pause argument as we dont need to execute promise code just yet
            var nextPromise=new Aaa(resolve,true);
                    
            this.thens.push(nextPromise);
    
            return nextPromise;
        }
    
    
        if(!pause)
            this.f(this.resolve,this.reject); 
     
    }
    
    
    var aaa=new Aaa(function(resolve,reject) {
    
        console.log(&quot;aaa&quot;);
    
        setTimeout(function() {
        	
        	console.log(&quot;fff&quot;);
            resolve(&quot;good&quot;);
            
        },2000);
    
        console.log(&quot;bbb&quot;);
    
    });

So now the promise can be created, called and resolved. Each `then` method will return new Aaa (Promise) so these can be chained. Now the code below uses promise created above and chains `then` callbacks. Each `then` returns new promise and in this case it seems to work fine:

    aaa.then(function(res) {
    
        console.log(&quot;ccc&quot;);
        console.log(res);
    
    })
    .then(function(res) {
        console.log(&quot;ddd&quot;);
        console.log(res);
    },function(rej) {
        console.log(&quot;eee&quot;);
        console.log(rej);
    });

the output I&#39;m getting is:

    ggg
    aaa 
    bbb 
    ggg 
    ggg 
    fff 
    ccc 
    good 
    ddd 
    undefined 

The problem is however when one of the `then` calls returns a promise:

    aaa.then(function(res) {
    
        console.log(&quot;ccc&quot;);
        console.log(res);
    
        // here we return the promise manually. then next then call where &quot;ddd&quot; is output should not be called UNTIL this promise is resolved. How to do that?
    
            return new Aaa(function(resolve,reject) {
    
            console.log(&quot;iii&quot;);
    
            setTimeout(function() {
            console.log(&quot;kkk&quot;);
                resolve(&quot;good2&quot;);
                // reject(&quot;bad&quot;);
    
            },2000);
    
            console.log(&quot;jjj&quot;);
    
        }).then(function (res) {
            console.log(&quot;lll&quot;);
    
            console.log(res);
        });
    
    })
    .then(function(res) {
        console.log(&quot;ddd&quot;);
        console.log(res);
    },function(rej) {
        console.log(&quot;eee&quot;);
        console.log(rej);
    });

The output is:

    ggg 
    aaa 
    bbb 
    ggg 
    ggg  
    fff  
    ccc  
    good  
    ggg  
    iii  
    jjj  
    ggg  
    ddd  
    undefined  
    kkk  
    lll  
    good2 


The call then where `ddd` is output should not be called UNTIL the returned promise we just added is resolved. 

How would that be best implemented? 






Basic Javascript promise implementation attempt

I&#39;m trying to load a JavaScript array with an array from my model. Its seems to me that this should be possible.

Neither of the below ways work.

Cannot create a JavaScript loop and increment through Model Array with JavaScript variable

    for(var j=0; j&lt;255; j++)
    {
        jsArray = (@(Model.data[j])));
    }

Cannot create a Razor loop, JavaScript is out of scope

    @foreach(var d in Model.data)
    {
        jsArray = d;
    }

I can get it to work with

    var jsdata = @Html.Raw(Json.Encode(Model.data)); 

But I don&#39;t know why I should have to use JSON. 

Also while at the moment I&#39;m restricting this to 255 bytes. In the future it could run into many MBs.



Razor MVC Populating Javascript array with Model Array

What I have:
-------------

I have jQuery AJAX function that returns HTML after querying a database. Depending on the result of the query, the function will either return HTML code or nothing (i.e. blank) as desired.

What I need:
-------------

I need to conditionally check for when the data is blank.

My code:
-------------

    $.ajax({
    	type:&quot;POST&quot;,
    	url: &quot;&lt;?php echo admin_url(&#39;admin-ajax.php&#39;); ?&gt;&quot;,
    	data: associated_buildsorprojects_form,
    	success:function(data){
    		if(!data){	
    		//if(data=&quot;undefined&quot;){
    		//if(data===&quot;undefined&quot;){
    		//if(data==null){
    		//if(data.length == 0){
    		//if ( data.length != 0 ){
    		//if(data===0){
    		//if(data===&quot;0&quot;){	
    			alert(&quot;Data: &quot; + data);
    		}
    	},
    	error: function(errorThrown){
    		alert(errorThrown);
    		alert(&quot;There is an error with AJAX!&quot;);
    	}  				
    });

My problem:
-------------

I&#39;ve tried a variety of conditions but none correctly check the data. Based on my findings, a blank alert message does not mean data is 

 1. empty
 2. non-existent
 3. equal to zero
 4. of length zero
 5. null
 6. undefined

If it&#39;s none of these things, how can I therefore conditionally check for the data that yields a blank alert message?

I&#39;m writing a simple site that takes as input an idiom, and return its meaning(s) and example(s) from Oxford Dictionary. Here&#39;s my idea:

I send a request to the following URL:

&lt;!-- language: lang-none --&gt;

    http://www.oxfordlearnersdictionaries.com/search/english/direct/?q=[idiom]

For example, if the idiom is “not go far”, I&#39;ll send a request to:

&lt;!-- language: lang-none --&gt;

    http://www.oxfordlearnersdictionaries.com/search/english/direct/?q=not+go+far

And I&#39;ll be redirected to the following page:

&lt;!-- language: lang-none --&gt;

    http://www.oxfordlearnersdictionaries.com/definition/english/far_1#far_1__192

On this page, I can extract the meaning(s) and the example(s) of the idiom. \
Here&#39;s my code for testing. It will alert the response URL:

&lt;!-- language: lang-html --&gt; 

    &lt;input id=&quot;idiom&quot; type=&quot;text&quot; name=&quot;&quot; value=&quot;&quot; placeholder=&quot;Enter your idiom here&quot;&gt;
	&lt;br&gt;
	&lt;button id=&quot;submit&quot; type=&quot;&quot;&gt;Submit&lt;/button&gt;
	&lt;script type=&quot;text/javascript&quot;&gt;
	$(document).ready(function(){
		$(&quot;#submit&quot;).bind(&#39;click&#39;,function(){
			var idiom=$(&quot;#idiom&quot;).val();
			$.ajax({
			    type: &quot;GET&quot;,
			    url: &#39;http://www.oxfordlearnersdictionaries.com/search/english/direct/&#39;,
			    data:{q:idiom},
			    async:true,
			    crossDomain:true,
			    success: function(data, status, xhr) {
			        alert(xhr.getResponseHeader(&#39;Location&#39;));
			    }
			});
			
		});
	});
	&lt;/script&gt;

The problem is I&#39;ve got an error: 

&gt; Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://www.oxfordlearnersdictionaries.com/search/english/direct/?q=by+far. This can be fixed by moving the resource to the same domain or enabling CORS.

Can anybody tell me how to resolve this please? \
Another approach is fine too.

Ajax Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource

I want to implement a simple file upload in my intranet-page, with the smallest setup possible.

This is my HTML part:

    &lt;input id=&quot;sortpicture&quot; type=&quot;file&quot; name=&quot;sortpic&quot; /&gt;
    &lt;button id=&quot;upload&quot;&gt;Upload&lt;/button&gt;

and this is my JS jquery script:

    $(&quot;#upload&quot;).on(&quot;click&quot;, function() {
        var file_data = $(&quot;#sortpicture&quot;).prop(&quot;files&quot;)[0];   
        var form_data = new FormData();
        form_data.append(&quot;file&quot;, file_data);
        alert(form_data);
        $.ajax({
            url: &quot;/uploads&quot;,
            dataType: &#39;script&#39;,
            cache: false,
            contentType: false,
            processData: false,
            data: form_data,                         
            type: &#39;post&#39;,
            success: function(){
            	alert(&quot;works&quot;); 
            }
        });
    });


There is a folder named &quot;uploads&quot; in the root directory of the website, with change permissions for &quot;users&quot; and &quot;IIS_users&quot;.

When I select a file with the file-form and press the upload button, the first alert returns &quot;[object FormData]&quot;. the second alert doesn&#39;t get called and the&quot;uploads&quot; folder is empty too!?

Can someone help my finding out whats wrong?

Also the next step should be, to rename the file with a server side generated name. Maybe someone can give me a solution for this, too.

jQuery AJAX file upload PHP

I am using `&lt;input type=&quot;file&quot;&gt;` to upload *audio* files.

To do that I am using `accept=&quot;audio/*&quot;`.  Because of this, the browser&#39;s file-select dialog shows only audio files by default.  However, there is an option called &quot;All Files&quot; in that dialog box that I don&#39;t want.

I&#39;m building a web application inside VueJS but I encounter a problem. I want to use a jQuery extension (cropit to be specific) but I don&#39;t know how to instantiate/require/import it the right way without getting errors.

I&#39;m using de official CLI tool and de webpack template for my App.

I included jQuery like this in my main.js file:

    import jQuery from &#39;jQuery&#39;
    window.jQuery = jQuery

Now I&#39;m building an image editor component where I want to instantiate crept like this: 
    
    export default {
      ready () {
        $(document).ready(function ($) {
          $(&#39;#image-cropper-wrapper-element&#39;).cropit({ /* options */ })
        })
      },
     }

But I keep getting errors...Now my question is how to properly instantiate jQuery and plugins via NPM/Webpack/Vue?

I&#39;m trying to install nodeJs into my Ubuntu 14.04 in order to use GruntJs.

I&#39;ve read about [Ubuntu different way][1] of doing it ([issues?][2]), so this is what I&#39;ve done in order to install it:

    sudo apt-get install npm

    sudo npm install -g grunt-cli

Typing grunt after that I&#39;ve got the error:

    0 to upgrade, 0 to newly install, 0 to remove and 3 not to upgrade.

I did try a cleanup just in case:

    sudo apt-get autoremove

But nope, the error is still there: when I type grunt I still get `/usr/bin/env: node: No such file or directory`

What should I do?

Cannot install NodeJs: /usr/bin/env: node: No such file or directory

I am looking for a better glob pattern for usemin, i want to to find all `.js` files but exclude the `.spec.js` files. I have the following solution so far.

```&lt;script src=&quot;components/**/*(.js|!(*.spec.js|*.scss))&quot;&gt;&lt;/script&gt;
```

The solution i have at the moment requires me to keep adding file extensions to exclude them, else they get picked up, for example `.html` files.

I tried to make it only look for `.js` files and exclude the `.spec.js` from them but it does not seem to work.

Also adding a `!components/**/*.spec.js` as another script below does not seem to work.

Node glob pattern for every .js file except .spec.js

So, I&#39;ve been looking all over for this, found &quot;similar&quot; answers here, but not exactly what I want.

Right now if I want to test a single file with karma, I need to do `fit()`, `fdescribe()` on the file in question...

However, what I do want is to be able to just call karma, with the config file, and direct it to a specific file, so I don&#39;t need to modify the file at all, ie:

`karma run --conf karma.conf.js --file /path/to/specific/test_file.js`

is it possible to do this? Or with any helper? (using grunt or gulp?)

Karma: Running a single test file from command line

I&#39;m trying to get into Grunt, which I am new to, but I do not understand its utility.

I understand that it is a taskrunner. I understand that it can be used to do things like bundle, uglify, jshint, minify, etc etc etc, anything that can be turned into a scripted task.

But I don&#39;t see what advantage this gives. Nearly all of these can be run from the command line anyway, which is to say you could just combine them using a simple shell script. It seems to me that setting up grunt + gruntfiles and writing tasks is *more* work than writing a shell script, rather than less.

What am I missing about this?
