Having just had the same problem I suspect your issue is that you&#39;re missing the `media=&quot;print&quot;` attribute on the `fullcalendar.print.css` style sheet link.

And if you&#39;re using Zend Framework to append the stylesheet, you can use this to add the media=&quot;print&quot;...

    $this-&gt;view-&gt;headLink()-&gt;appendStylesheet(&#39;/styles/jquery-plugins/fullcalendar.print.css&#39;, &#39;print&#39;);

I have GitLab &amp; GitLab CI set up to host and test some of my private repos. For my composer modules under this system, I have Satis set up to resolve my private packages.

Obviously these private packages require an ssh key to clone them, and I have this working in the terminal - I can run composer install and get these packages, so long as I have the key added with `ssh-add` in the shell.

However, when running my tests in GitLab CI, if a project has any of these dependencies the tests will not complete as my GitLab instance needs authentication to get the deps (obviously), and the test fails saying `Host key verification failed`.

My question is how do I set this up so that when the runner runs the test it can authenticate to gitlab without a password? I have tried putting a password-less ssh-key in my runners `~/.ssh` folder, however the build wont even add the key, &quot;eval `ssh-agent -s`&quot; followed by ssh-add seems to fail saying the agent isn&#39;t running...

Getting GitLab CI to clone private repositories

I am writing a C++ library (header-only) and am using CMake to generate my (Visual Studio) project and solution files. I&#39;m also writing a test suite, which is part of the same CMake project.

My problem occurs when I call target_include_directories() on the target that represents my header-only library, so that consumers of my library may find its header files. I get the following error message (even though generation is NOT aborted).

    CMake Error in CMakeLists.txt:
      Target &quot;Fonts&quot; INTERFACE_INCLUDE_DIRECTORIES property contains path:

        &quot;D:/Projects/GPC/fonts/include&quot;

      which is prefixed in the source directory.

(D:/Projects/GPC/Fonts being the top-level directory of my library project. Btw the problem remains if I move my header files to the top directory.)

The offending line in my CMakeLists.txt is this (adapted for simplicity):

    target_include_directories(Fonts INTERFACE &quot;${CMAKE_CURRENT_SOURCE_DIR}/include&quot;)

I do not understand what I&#39;m doing wrong. Without target_include_directories(), code of consumer projects simply can&#39;t include my header files (unless in installed form, but I haven&#39;t gotten to that yet, and in any case I want to be able to use my library from its build tree, without installation.)

I feel like I&#39;m missing something basic here; yet I&#39;ve searched for hours without finding a solution or explanation.

I am using [fullCalendar][1] as below
and have defined header section, everything works ok except header where it&#39;s only showing title but
next, prev, month view etc buttons are missing

if I remove word &#39;title&#39; it removes title so it seems to be doing something but just not showing buttons, any ideas why? am I missing something?
my code looks like below:

    jQuery(&#39;#calendar&#39;).fullCalendar({
    	header: {
    		left: &#39;prev,next today&#39;,
    		center: &#39;title&#39;,

I have the follow situation:

    	    	var myitem = JSON.parse(message.body);
    	    	
    	    });

all works fine, the problem is that on the javascript console is full of debug messages like this:

    &lt;&lt;&lt; MESSAGE
    content-type:application/json;charset=UTF-8
    subscription:sub-1
    message-id:o6g660dt-113
    destination:/topic/mytopic
    content-length:411

And I want to disable the messages.

I tried to change some option and also tried to register simply:

    var socket = new SockJS(&quot;/mmyurl/&quot;);

but it doesn&#39;t work.

Is there a way to disable the debug messages?

Any help is appreciated

I am using Thymeleaf as template engine. How I pass a variable from Spring model to JavaScript variable?


Spring-side:

    @RequestMapping(value = &quot;message&quot;, method = RequestMethod.GET)
    public String messages(Model model) {
        model.addAttribute(&quot;message&quot;, &quot;hello&quot;);
        return &quot;index&quot;;
    }

Client-side:

    &lt;script&gt;
        ....
        var m = ${message}; // not working
        alert(m);
        ...
    &lt;/script&gt;


Setting up a JavaScript variable from Spring model by using Thymeleaf

I&#39;m rewriting my app to use Flux and I have an issue with retrieving data from Stores. I have a lot of components, and they nest a lot. Some of them are large (`Article`), some are small and simple (`UserAvatar`, `UserLink`).

I&#39;ve been struggling with where in component hierarchy I should read data from Stores.  
I tried two extreme approaches, neither of which I quite liked:

## All entity components read their own data

Each component that needs some data from Store receives just entity ID and retrieves entity on its own.  
For example, `Article` is passed `articleId`, `UserAvatar` and `UserLink` are passed `userId`.

This approach has several significant downsides (discussed under code sample).


    var Article = React.createClass({
      mixins: [createStoreMixin(ArticleStore)],

      propTypes: {
        articleId: PropTypes.number.isRequired
      },

      getStateFromStores() {
        return {
          article: ArticleStore.get(this.props.articleId);
        }
      },

      render() {
        var article = this.state.article,
            userId = article.userId;

        return (
          &lt;div&gt;
            &lt;UserLink userId={userId}&gt;
              &lt;UserAvatar userId={userId} /&gt;
            &lt;/UserLink&gt;

            &lt;h1&gt;{article.title}&lt;/h1&gt;
            &lt;p&gt;{article.text}&lt;/p&gt;

            &lt;p&gt;Read more by &lt;UserLink userId={userId} /&gt;.&lt;/p&gt;
          &lt;/div&gt;
        )
      }
    });

    var UserAvatar = React.createClass({
      mixins: [createStoreMixin(UserStore)],

      propTypes: {
        userId: PropTypes.number.isRequired
      },

      getStateFromStores() {
        return {
          user: UserStore.get(this.props.userId);
        }
      },

      render() {
        var user = this.state.user;

        return (
          &lt;img src={user.thumbnailUrl} /&gt;
        )
      }
    });

    var UserLink = React.createClass({
      mixins: [createStoreMixin(UserStore)],

      propTypes: {
        userId: PropTypes.number.isRequired
      },

      getStateFromStores() {
        return {
          user: UserStore.get(this.props.userId);
        }
      },

      render() {
        var user = this.state.user;

        return (
          &lt;Link to=&#39;user&#39; params={{ userId: this.props.userId }}&gt;
            {this.props.children || user.name}
          &lt;/Link&gt;
        )
      }
    });


Downsides of this approach:

* It&#39;s frustrating to have 100s components potentially subscribing to Stores;
* It&#39;s **hard to keep track of how data is updated and in what order** because each component retrieves its data independently;
* Even though you might *already* have an entity in state, you are forced to pass its ID to children, who will retrieve it again (or else break the consistency).

## All data is read once at the top level and passed down to components

When I was tired of tracking down bugs, I tried to put all data retrieving at the top level. This, however, proved impossible because for some entities I have several levels of nesting.

For example:

* A `Category` contains `UserAvatar`s of people who contribute to that category;
* An `Article` may have several `Category`s.

Therefore if I wanted to retrieve all data from Stores at the level of an `Article`, I would need to:

* Retrieve article from `ArticleStore`;
* Retrieve all article&#39;s categories from `CategoryStore`;
* Separately retrieve each category&#39;s contributors from `UserStore`;
* Somehow pass all that data down to components.

Even more frustratingly, whenever I need a deeply nested entity, I would need to add code to each level of nesting to additionally pass it down.

## Summing Up

Both approaches seem flawed. How do I solve this problem most elegantly?

My objectives:

* Stores shouldn&#39;t have an insane number of subscribers. It&#39;s stupid for each `UserLink` to listen to `UserStore` if parent components already do that.

* If parent component has retrieved some object from store (e.g. `user`), I don&#39;t want any nested components to have to fetch it again. I should be able to pass it via props.

* I shouldn&#39;t have to fetch all entities (including relationships) at the top level because it would complicate adding or removing relationships. I don&#39;t want to introduce new props at all nesting levels each time a nested entity gets a new relationship (e.g. category gets a `curator`).

At what nesting level should components read entities from Stores in Flux?

One of the things I appreciate the most about Backbone.js is how simple and elegant inheritance works. I&#39;m starting to get to grips with React, and can&#39;t really find anything in react that resembles this Backbone code

    var Vehicle = Backbone.View.extend({
    	methodA: function() { // ... }
    	methodB: function() { // ... }
    	methodC: function() { // ... }
    });
    
    var Airplane = Vehicle.extend({
    	methodC: function() {
    		// Overwrite methodC from super
    	}
    });

In react we [have mixins](http://facebook.github.io/react/docs/reusable-components.html#mixins), and using those we could get somewhat close to the above example if we went like this

    var vehicleMethods = {
        methodA: function() { // ... }
        methodB: function() { // ... }
    }
    
    var Vehicle = React.createClass({
        mixins: [vehicleMethods]
        methodC: function() { 
            // Define method C for vehicle
        }
    });
    
    var Airplane = React.createClass({
        mixins: [vehicleMethods]
        methodC: function() {
            // Define method C again for airplane
        }
    });

This is less repetitive than defining the same stuff over and over again, but it doesn&#39;t seem to be nearly as flexible as the Backbone way. For instance, I get an error if I try to redefine/overwrite a method that exists in one of my mixins. On top of that, the React.js way is more code for me to write.

There is some incredibly clever stuff in react, and it feels like this is more the case of me not getting how to properly do this, than it feels like a feature missing from React.

Any pointers are greatly appreciated.


Extending React.js components

I&#39;m using Bootstrap 3.0.2 and the [Bootstrap-select][1] plugin.


**Here&#39;s my select list**:

&lt;!-- language: lang-html --&gt;

    &lt;select class=&quot;selectpicker&quot; data-live-search=&quot;true&quot; data-size=&quot;7&quot;&gt;
	  &lt;option&gt;Petr Karel&lt;/option&gt;
      &lt;option&gt;Honza Nov&#225;k&lt;/option&gt;
      &lt;option&gt;David Egydy&lt;/option&gt;
      &lt;option&gt;Sl&#225;va Kov&#225;ř&lt;/option&gt;
      &lt;option&gt;Hana Skalick&#225;&lt;/option&gt;
      &lt;option&gt;Simona Kol&#225;řov&#225;&lt;/option&gt;
      &lt;option&gt;Kateřina Sychov&#225;&lt;/option&gt;
      &lt;option&gt;Am&#225;lka Sychov&#225;&lt;/option&gt;
      &lt;option&gt;Jana Sychov&#225;&lt;/option&gt;
      &lt;option&gt;Magdal&#233;na Sychov&#225;&lt;/option&gt;
      &lt;option&gt;Tereza Sychov&#225;&lt;/option&gt;
      &lt;option&gt;Bohdana Sychov&#225;&lt;/option&gt;
    &lt;/select&gt;

**Here&#39;s my JavaScript**:

&lt;!-- language: lang-js --&gt;         

    //inicialization of select picker
    $(&#39;.selectpicker&#39;).selectpicker();
     
    //on change function i need to control selected value
    $(&#39;select.selectpicker&#39;).on(&#39;change&#39;, function(){
       var selected = $(&#39;.selectpicker option:selected&#39;).val();
       alert(selected);
    });


### Issue

My problem is that change function won&#39;t work. It doesn&#39;t do anything, and I can&#39;t find solution by myself.

If i put it into document ready instead change function it seems to be working. So i guess i have mistake somewhere in: 

    $(&#39;select.selectpicker&#39;).on(&#39;change&#39;, function(){

I also tried to use only: 

    $(&#39;.selectpicker&#39;).on(&#39;change&#39;, function(){

without this select prefix but nothing changes.

### UPDATE

Solution is putting jquery code into `document.ready()`. Thanks to [Kartikeya][2]

Bootstrap-select - how to fire event on change

This is a conceptual question. In my particular case, I am using [slick.js][1] to create an image carousel for a website. Since these are high resolution photographs, I want to speed up the page load time by allowing the photographs to be loaded asynchronously instead of on page load.

When looking through the documentation for this library, I saw the settings available for the &#39;lazyLoad&#39; property with little information as to what those settings mean in practice.

Essentially my question is, what is the difference between progressive and on-demand in the context of lazy loading.

Brand new to JS.    	
I am trying to check if the file input element is empty when submitting the form with jQuery/JavaScript.
I have gone through a bunch of solutions and nothing is working for me.  I am trying to avoid the `/c/fakepath` (unless there is no other option)

    &lt;input type=&quot;file&quot; name=&quot;videoFile&quot; id=&quot;videoUploadFile&quot; /&gt;

This does not work:

    var vidFile = $(&quot;#videoUploadFile&quot;).value;

The only way I can get the filename is if I use the following:

    var vidFile = document.getElementById(&quot;videoUploadFile&quot;).files[0].name;

If there is no file available the code throws an error: 
&gt;cannot read property name of undefined

which makes sense because the array is not set. but I cannot figure out how to do any error handling with this.

How do I properly grab the file input element `videoUploadFile`, check if it&#39;s empty, throw an error message if it&#39;s empty?
