As I delve into customizing a template within a directive and incorporating references to attributes in the parent scope, I find myself navigating through the Angular framework as a newcomer. My journey has led me to leaning on Customizing the template within a Directive, yet I hit a roadblock when attempting to pass a reference to a parent-scoped variable as an attribute to the directive; it remains unresolved, perhaps due to its undefined state at the time the compile function is invoked.
The blueprint of my directive appears as follows:
app.directive('sectionHeader', function() {
return {
restrict: 'EC',
replace: true,
transclude: true,
scope: {sectionName:'@sectionName', imageUrl:'@imageUrl'},
compile: function(element, attrs) {
var imageHtml = attrs.hasOwnProperty('imageUrl') ? '<div style="float: left; padding-right: 5px;"><img class="float_left" src="' + attrs.imageUrl + '" alt=""/></div>' : '';
var htmlText =
'<div>' + imageHtml + '<h1 class="float-left">' + attrs.sectionName + '</h1>' +
'<div class="clear"></div>' +
'<div class="modal_hr"></div></div>';
element.replaceWith(htmlText);
},
};
});
Meanwhile, the directive usage scenario unfolds like this:
<div class="section-header" section-name="{{currentFeatureName}}"></div>
The hitch lies in the fact that the {{currentFeatureName}} variable from my controller seemingly lacks definition during the compilation process triggered by the directive.
In brainstorming potential workarounds, one idea involved establishing an observer function within the compile phase that monitors changes to the sectionName attribute, updating the h1 element's content accordingly. However, this approach struck me as somewhat cumbersome, prompting me to inquire if there exists a more streamlined or elegant alternative.
