I have an anchor tag that I wish to hide or show depending on a value in the model.
<table>
<tr ng-repeat="item in items">
<td>Other Stuff</td>
<td>
<a href="#/somewhere" ng-show="model.showIt" myCustomDir="some value" onClick="bar(item)" />
</td>
</tr>
</table>
Now in my directive I have the following:
app.directive('myCustomDir', function() {
var def = {
restrict: 'A',
scope: {
onClick: "&"
},
link: function(scope, element, attrs) {
var hover = angular.element("<div><b>Some Text</b></div>");
var button = hover.find('b');
button.on('click', function() {
scope.$apply(function() {
scope.onClick();
})
});
}
};
return def;
})
The problem is as soon as I include my directive the ng-show one I think no longer works and that is because if I am correct it is because my directive works in isolate scope so the model from the parent scope is no longer present.
How would I get my directive to play nicely with ng-show while still being able to let someone what method they want to call when the tag is clicked.
Plunker for all those interested. http://plnkr.co/edit/BLMCgB

You directive creates an isolated scope. So you need to use $parent
to get the value of the current repeater item
ng-show="$parent.item.visible"
If you want to make it more generic, you can take the scope off to make it compatible with other directives. Then you can use scope.$eval
to call the function passed in.
myApp.directive('myDirective', function ($document) {
var definition = {
restrict: 'A',
link: function (scope, element, attrs) {
element.on('click', function () {
...
button.on('click', function () {
scope.$apply(function () {
scope.$eval(attrs.onClick);
hover.remove();
})
});
});
}
}
return definition;
})

If you want allow any global directive - don't declare private scope.
If you want allow only few directives, add links in scope declaration:
scope: {
onClick: "&",
ngShow : "&"
},
To your question in comments:
Declare controller in directive and declare method in this controller. Then in directive template assign ng-click to this method.
var def = {
restrict: 'A',
controller: function($scope){
$scope.callMe = function(){
console.log('foo');
}
}
}
in template:
<div ng-click="callMe()">content</div>
This method will be accessible only inside your directive.
