An AngularJS directive with itself as the attribute

Because this took me quite a while to figure out, I thought I'd share in case somebody else is falling into the same pit of confusion.

When you write an attribute directive in angularjs you might want to have it fed by an attribute value.
For example, something like this:

<div my-attribute="somevalue"></div>

How then do you create a new scope that takes that in? It's not obvious. Any here's how you do it:

app.directive('myAttribute', function() {
    return {
        restrict: 'A',
        scope: {
            myAttribute: '='
        template: '<div style="font-weight:bold">{{ myAttribute | number:2 }}</div>'

The trick to notice is that the "self attribute" because the name of the attribute in camel case.

Thanks @mythmon for helping me figure this out.


Thanks !!

That use case is almost never highligthed in docs and blogs, but very useful !!
Thanks! Been looking all over for this piece of information.
great, thanks
If your attribute contains text, use '@' instead of '='.
