How to show/hide a View in EmberJS

ember.js, javascript, jquery

Solution

I would create a simple `isVisibleBinding` to the view you want to hide/show, see http://jsfiddle.net/pangratz666/dTV6q/:

Handlebars:

<script type="text/x-handlebars" >
    {{#view App.ParentView}}
        <h1>Parent</h1>
        <div>
            <a href="#" {{action "toggle"}}>hide/show</a>
        </div>     
        {{#view App.ChildView isVisibleBinding="isChildVisible" }}
            {{view Em.TextArea rows="2" cols="20"}}
        {{/view}}        
    {{/view}}
</script>​

JavaScript:

App.ParentView = Em.View.extend({   
    isChildVisible: true,

    toggle: function(){
        this.toggleProperty('isChildVisible');
    }
});

App.ChildView = Ember.View.extend();

A note about your naming conventions: classes should be named `UpperCase` and instances `lowerCase`. See blog post about this.

Problem

I want a View to be hidden on load, then when a user clicks on a link it will display the view. Can someone review my code and let me know what I have done wrong? ``` App.parentView = Em.View.extend({ click: function() { App.childView.set('isVisible', true); } }); App.childView = Em.View.extend({ isVisible: false }); ``` Here is the jsfiddle: http://jsfiddle.net/stevenng/uxyrw/5/
