How can you change a CSS property in Ember using a view and then display it?

I have a specific color saved in my database as text (for example: "#FFFFFF") and I am looking to display it similarly to the way shown in this demonstration:

http://jsfiddle.net/rLtb7dc7/

This is what I currently have...

HTML:

<span class="colorpreview"> {{view App.ColorView contentBinding="primaryColor"}} random text</span>

View:

App.ColorView = Ember.View.extend({
    tagName: "span",
    classNameBindings: 'colorpreview',

    'colorpreview': function() {
        var colorFromDatabase = this.content;
        $('.colorpreview').css('background-color', colorFromDatabase);
    }.property('content')
});

CSS:

.colorpreview{
    width: 10px ;
    height: 10px ;
    border-radius: 10px ;
    background-color: #FFF ;
}

If more code or information is needed, feel free to ask in the comments. Thank you in advance! ;)

Answer №1

To achieve this effect, I utilized a helper function:

Ember.Handlebars.registerBoundHelper("applyStyle", function(color){
    return "background-color:" + color + ";" + "border-radius: 10px; padding: 5px; display: inline-block; vertical-align: middle; border:1px solid black"; 
});

In this scenario, 'color' represents the primaryColor that needed to be displayed.

The helper function was then called within the HTML like so:

<span style="{{unbound applyStyle primaryColor}}" >  </span>
