There should not be a space between the 2 selectors

    document.querySelector(&#39;[data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot;][data-period=&quot;current&quot;]&#39;)

if you give a space between them it will become a [descendant selector][1], ie it will search for an element attribute `data-period=&quot;current&quot;` which is inside an element with `data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot;` like

    &lt;div class=&quot;text-right&quot; data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot;&gt;
        &lt;div data-period=&quot;current&quot;&gt;-&lt;/div&gt;
    &lt;/div&gt;


  [1]: https://developer.mozilla.org/en-US/docs/Web/CSS/Descendant_selectors

space in selector looks for `[data-period=&quot;current&quot;]` in`[data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot;]` .You don&#39;t need to put space in between attribute value selector:

    document.querySelector(&#39;[data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot;][data-period=&quot;current&quot;]&#39;)

I want to change the default terminal app used by Visual Studio Code for Mac. I am thinking it is part of preferences or settings json, but unsure.

Change default terminal app in Visual Studio Code on Mac

I believe this question is similar to [this one][1] but the terminology is different. From the Mongoose 4 [documentation][2]:

&gt; We may also define our own custom document instance methods too.

    // define a schema
    var animalSchema = new Schema({ name: String, type: String });
    
    // assign a function to the &quot;methods&quot; object of our animalSchema
    animalSchema.methods.findSimilarTypes = function (cb) {
      return this.model(&#39;Animal&#39;).find({ type: this.type }, cb);
    }
&gt;Now all of our animal instances have a findSimilarTypes method available to it.


And then:


&gt; Adding static methods to a Model is simple as well. Continuing with our animalSchema:

    // assign a function to the &quot;statics&quot; object of our animalSchema
    animalSchema.statics.findByName = function (name, cb) {
      return this.find({ name: new RegExp(name, &#39;i&#39;) }, cb);
    }
    
    var Animal = mongoose.model(&#39;Animal&#39;, animalSchema);
    Animal.findByName(&#39;fido&#39;, function (err, animals) {
      console.log(animals);
    });

It seems with static methods each of the animal instances would have the `findByName` method available to it as well.  What are the `statics` and `methods` objects in a Schema? What is the difference and why would I use one over the other?

I&#39;m trying to find an element with `document.querySelector` which has *multiple data-attributes*:

    &lt;div class=&quot;text-right&quot; data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot; data-period=&quot;current&quot;&gt;-&lt;/div&gt;

But it does not work. &lt;br&gt;
However, it works well, if I put the second data-attribute in a child-element like:

    &lt;div class=&quot;text-right&quot; data-point-id=&quot;7febe088-4eca-493b-8455-385b39ad30e3&quot;&gt; &lt;span data-period=&quot;current&quot;&gt;-&lt;/span&gt; &lt;/div&gt;

So, is there an option to search for **both attributes at once**?&lt;br&gt;I&#39;ve tried several options but I don&#39;t get it.

For a new module I&#39;m trying to use [`npm build`][1] without gulp / Grunt / other specialised build tools.

    &quot;scripts&quot;: {
  	  &quot;build&quot;: &quot;node build.js&quot;
    },

My build.js is simply

    console.log(&#39;Hello&#39;)

However, running

    npm build

Simply exits without printing anything, with a status of 0. 

Running:

    npm install

Also does all the normal things, but does not run build.js either.

**How can I make npm run my build script?**

Edit: even simple bash commands don&#39;t seem to work, eg 

    &quot;scripts&quot;: {
  	    &quot;build&quot;: &quot;touch TESTFILE&quot;
    },

Doesn&#39;t make a file with that name.

I know I can do it using loops, but I&#39;m trying to find an elegant way of doing this:

I have two jagged arrays (array of arrays):

    var array1 = [[&#39;a&#39;, &#39;b&#39;], [&#39;b&#39;, &#39;c&#39;]];
    var array2 = [[&#39;b&#39;, &#39;c&#39;], [&#39;a&#39;, &#39;b&#39;]];

I want to use `lodash` to confirm that the above two jagged arrays are the same. By &#39;the same&#39; I mean that there is no item in `array1` that is not contained in `array2`. Notice that the items in jagged array are actually arrays. So I want to compare between inner arrays.

In terms of checking equality between these items:

    [&#39;a&#39;, &#39;b&#39;] == [&#39;b&#39;, &#39;a&#39;] 

or

    [&#39;a&#39;, &#39;b&#39;] == [&#39;a&#39;, &#39;b&#39;] 

Both work since the letters will always be in order.

---
**UPDATE**: Original question was talking about to &quot;arrays&quot; (instead of jagged arrays) and for years many people discussed (and added answers) about comparing simple one-dimensional arrays (without noticing that the examples provided in the question were not actually similar to the simple one-dimensional arrays they were expecting).

I need to create a simple but accurate timer.

This is my code:

    var seconds = 0;
    setInterval(function() {
    timer.innerHTML = seconds++;
    }, 1000);


After exactly 3600 seconds, it prints about 3500 seconds.

- Why is it not accurate?

- How can I create an accurate timer?

How can you achieve either a hover event or active event in ReactJS when you do inline styling?

I&#39;ve found that the onMouseEnter, onMouseLeave approach is buggy, so hoping there is another way to do it.

Specifically, if you mouse over a component very quickly, only the onMouseEnter event is registered. The onMouseLeave never fires, and thus can&#39;t update state... leaving the component to appear as if it still is being hovered over. I&#39;ve noticed the same thing if you try and mimic the &quot;:active&quot; css pseudo-class. If you click really fast, only the onMouseDown event will register. The onMouseUp event will be ignored... leaving the component appearing active.

Here is a JSFiddle showing the problem: https://jsfiddle.net/y9swecyu/5/

I am trying to capture the submit button press of my form and if the form is submitted, the page refreshes and I show a few hidden fields. I would like to capture whether the form has been submitted before or not and if it submitted on reload, I would like to unhide the hidden fields. I was trying to use a global variable to achieve this, however I was unable to make it work properly.

Here is what I tried:

&lt;!-- language: lang-js --&gt;

      var clicked = false;

      $(document).ready(function() {

        $(&quot;input[type=&#39;submit&#39;][value=&#39;Search&#39;]&quot;).attr(&quot;onclick&quot;, &quot;form.act.value=&#39;detailSearch&#39;; clicked = true;  return true;&quot;);

        if (clicked == true) {
          // show hidden fields
        } else {
          // don&#39;t show hidden fields
        }
      });

Any suggestions on what is wrong with this code?

Persist variables between page loads

I have managed to get ReCaptcha 2.0 working in my website. However, it&#39;s only working when I don&#39;t use AJAX and I let the form submit &quot;naturally&quot;.  
  
I want to submit the form with the captcha and alert the user with a success note **without refreshing the page**. 
  
  
I tried the following code, but it seems like the server doesn&#39;t get the user response:  
  
**HTML:**

    &lt;form class=&quot;form&quot; action=&quot;javascript:void(0)&quot; novalidate&gt;
        &lt;!-- all the inputs... --&gt;
     
    	&lt;!-- captcha --&gt;
    	&lt;div class=&quot;input-group&quot;&gt;
    		&lt;div class=&quot;g-recaptcha&quot; data-sitekey=&quot;6LdOPgYTAAAAAE3ltWQGar80KUavaR-JblgPZjDI&quot;&gt;&lt;/div&gt;
    	&lt;/div&gt;
     
    	&lt;div class=&quot;errors&quot; id=&quot;errors&quot; style=&quot;display: none&quot;&gt;&lt;/div&gt;
     
    	&lt;div class=&quot;input-group&quot;&gt;
    		&lt;input type=&quot;button&quot; value=&quot;Send&quot; class=&quot;btn-default right&quot; id=&quot;submit&quot;&gt;
    		&lt;div class=&quot;clear&quot;&gt;&lt;/div&gt;
    	&lt;/div&gt;
    &lt;/form&gt;

**JS:**

    $(&#39;#submit&#39;).click(function(e) {
		console.log(&#39;clicked submit&#39;); // --&gt; works
 
		var $errors = $(&#39;#errors&#39;),
			$status = $(&#39;#status&#39;),
 
			name = $(&#39;#name&#39;).val().replace(/&lt;|&gt;/g, &quot;&quot;), // prevent xss
			email = $(&#39;#email&#39;).val().replace(/&lt;|&gt;/g, &quot;&quot;),
			msg = $(&#39;#message&#39;).val().replace(/&lt;|&gt;/g, &quot;&quot;);
 
		if (name == &#39;&#39; || email == &#39;&#39; || msg == &#39;&#39;) {
			valid = false;
			errors = &quot;All fields are required.&quot;;
		}
 
        // pretty sure the problem is here
		console.log(&#39;captcha response: &#39; + grecaptcha.getResponse()); // --&gt; captcha response: 
 
		if (!errors) {
			// hide the errors
			$errors.slideUp();
			// ajax to the php file to send the mail
			$.ajax({
				type: &quot;POST&quot;,
				url: &quot;http://orenurbach.com/assets/sendmail.php&quot;,
				data: &quot;email=&quot; + email + &quot;&amp;name=&quot; + name + &quot;&amp;msg=&quot; + msg + &quot;&amp;g-recaptcha-response=&quot; + grecaptcha.getResponse()
			}).done(function(status) {
				if (status == &quot;ok&quot;) {
					// slide down the &quot;ok&quot; message to the user
					$status.text(&#39;Thanks! Your message has been sent, and I will contact you soon.&#39;);
					$status.slideDown();
					// clear the form fields
					$(&#39;#name&#39;).val(&#39;&#39;);
					$(&#39;#email&#39;).val(&#39;&#39;);
					$(&#39;#message&#39;).val(&#39;&#39;);
				}
			});
		} else {
			$errors.text(errors);
			$errors.slideDown();
		}
	});

**PHP:**

    &lt;?php
        // assemble the message from the POST fields
    
    	// getting the captcha
    	$captcha = &#39;&#39;;
    	if (isset($_POST[&#39;g-recaptcha-response&#39;]))
    		$captcha = $_POST[&#39;g-recaptcha-response&#39;];
    	echo &#39;captcha: &#39;.$captcha;
    
    	if (!$captcha)
    		echo &#39;The captcha has not been checked.&#39;;
    	// handling the captcha and checking if it&#39;s ok
    	$secret = &#39;MY_SECRET&#39;;
    	$response = json_decode(file_get_contents(&quot;https://www.google.com/recaptcha/api/siteverify?secret=&quot;.$secret.&quot;&amp;response=&quot;.$captcha.&quot;&amp;remoteip=&quot;.$_SERVER[&#39;REMOTE_ADDR&#39;]), true);
    
    	var_dump($response);
    
    	// if the captcha is cleared with google, send the mail and echo ok.
    	if ($response[&#39;success&#39;] != false) {
    		// send the actual mail
    		@mail($email_to, $subject, $finalMsg);
    
    		// the echo goes back to the ajax, so the user can know if everything is ok
    		echo &#39;ok&#39;;
    	} else {
    		echo &#39;not ok&#39;;
    	}
    ?&gt;

  
  
**The result** in the PHP page:

    captcha: The captcha has not been checked.array(2) { [&quot;success&quot;]=&gt; bool(false) [&quot;error-codes&quot;]=&gt; array(1) { [0]=&gt; string(22) &quot;missing-input-response&quot; } } not ok
  
  
**Bottom line** is, how can I get the input response manually without it automatically going with the rest of the POST data?

ReCaptcha 2.0 With AJAX

I have a very simple form as follows. I want to make it so that the Submit button is disabled, and only enabled **after** the user has successfully completed the ReCaptcha.

I&#39;m assuming I&#39;m going to need some Javascript / jQuery to do this.

Google&#39;s documentation on ReCaptcha 2.0 seems really sparse and dense (to me, anyway). I&#39;d appreciate some pointers:

    &lt;form action=&quot;something.php&quot; method=&quot;post&quot;&gt;
        Name: &lt;input type=&quot;text&quot; size=&quot;40&quot; name=&quot;name&quot;&gt;&lt;br&gt;&lt;br&gt;
        &lt;div class=&quot;g-recaptcha&quot; data-sitekey=&quot;############-#####&quot;&gt;&lt;/div&gt;
        &lt;input type=&quot;submit&quot; value=&quot;Submit&quot; &gt;
    &lt;/form&gt;

ReCaptcha 2.0: enable Submit button on callback if recaptcha successful

My cordova version is **5.0.0**

I am getting a 404 error for the all ajax request made when the app is deployed on the device. On the web browser, it works fine but same app when deployed on a device does not work.

I tried adding following to solve the issue but it hasn&#39;t helped.

**Config.xml**

    &lt;access origin=&quot;*&quot; /&gt;

**AndriodManiest.xml**

    &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot; /&gt;
    &lt;uses-permission android:name=&quot;android.permission.ACCESS_NETWORK_STATE&quot; /&gt;
    &lt;uses-permission android:name=&quot;android.permission.READ_PHONE_STATE&quot; /&gt;

I also added following in my index.html file but it didn&#39;t make any difference either.

    &lt;script&gt;
        $.support.cors=true;
    &lt;/script&gt;

Anyone here has another trick to solve this issue?, Seems to be a quite common issue with phonegap but the fixes above worked in older vesion of the phonegap/cordova but non of them has worked in my case.

Any help would be great.

**Problem:**

I have a SELECT-element in my page, which is filled in with an `ng-repeat`. It also has a `ng-model` which has a default value.

When I change the value, the `ng-model` adapts, that&#39;s ok. But the dropdown-list shows an empty slot at launch, where it should have the item with the default value selected instead.


**Code**

    &lt;div ng-app ng-controller=&quot;myCtrl&quot;&gt;
        &lt;select class=&quot;form-control&quot; ng-change=&quot;unitChanged()&quot; ng-model=&quot;data.unit&quot;&gt;
             &lt;option ng-repeat=&quot;item in units&quot; ng-value=&quot;item.id&quot;&gt;{{item.label}}&lt;/option&gt;
        &lt;/select&gt;
    &lt;/div&gt;

With JS:

    function myCtrl ($scope) {
        $scope.units = [
            {&#39;id&#39;: 10, &#39;label&#39;: &#39;test1&#39;},

AngularJs - ng-model in a SELECT

I&#39;m looking for a way to detect if a click event happened outside of a component, as described in this [article][1]. jQuery closest() is used to see if the target from a click event has the dom element as one of its parents. If there is a match the click event belongs to one of the children and is thus not considered to be outside of the component.

So in my component I want to attach a click handler to window. When the handler fires I need to compare the target with the dom children of my component.

The click event contains properties like &quot;path&quot; which seems to hold the dom path that the event has travelled. I&#39;m not sure what to compare or how to best traverse it, and I&#39;m thinking someone must have already put that in a clever utility function... No?

Can the DOM objects be accessed while building electron apps? or is there any other alternative way that can give me the required functionality?

I am unable to find an explicit reference for the use of these functions:
`getBBox()` vs `getBoundingClientRect()` vs `getClientRects()`.

Could you explain what they do and what are the coordinates (and their referential) they return?

In Google Chrome’s Developer Tools, I see a `#shadow-root` right under `&lt;html lang=&quot;en&quot;&gt;` tag. what does it do and what is it used for? I don’t see it in Firefox nor in IE; only in Chrome, is this a special feature?

If I open it, it shows `&lt;head&gt;` and `&lt;body&gt;` and a link beside named `reveal`, by clicking, it points to the `&lt;head&gt;` and `&lt;body&gt;`, nothing else.

I have part of a React Component that looks like this:

    var headerElement = someBoolean ? &lt;input/&gt; : &#39;some string&#39;;
    return &lt;th onClick={this._onHeaderClick}&gt;{headerElement}&lt;/th&gt;;

And a click handler for the `th` element:

    _onHeaderClick(event) {
        event.preventDefault();
        console.log(event.target);
    },

I want to capture the `th` element. It works fine when `headerElement` is &#39;some string&#39;, but when it is an `input` element, the `input` element is the one referenced in the `event.target` property.

What&#39;s the best way to achieve this?

What is the proper way to loop through literals of an enum in TypeScript?

(I am currently using TypeScript 1.8.1.)

I&#39;ve got the following enum:

    export enum MotifIntervention {
        Intrusion,
        Identification,
        AbsenceTest,
        Autre
    }

    export class InterventionDetails implements OnInit
    {
        constructor(private interService: InterventionService)
        {
            let i:number = 0;
            for (let motif in MotifIntervention) {
                console.log(motif);
            }
        }

The result displayed is a list

    0
    1
    2
    3
    Intrusion,
    Identification,
    AbsenceTest,
    Autre

I do want only four iterations in the loop as there are only four elements in the enum. I don&#39;t want to have 0 1 2 and 3 that seem to be index numbers of the enum.
