问题
I'm thinking this should be simple but I'm missing something. How can I pass a flowObj in my ng-repeat below to my Directive? I want to pass it to my directive then on click use that FlowObj then apply some logic. I tried using the commented code in my directive
scope: {
test:"@"
}
But it seems to screw up my css .
HTML:
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<div id="center_outer">
<div id="center_inner" ng-controller="CtrlPageFlow">
<div flowclick class="cflow" ng-repeat="flowObj in flows" >
{{flowObj.name}}
</div>
</div>
</div>
</body>
</html>
Here is my directive
angular.module('directives', ['opsimut']).directive('flowclick', function() {
return {
/*
scope: {
test:"@" // set the attribute name on the directive's scope
},
*/
link: function(scope, elem, attr) {
elem.bind('click', function(scope) {
debugger;
alert(scope.flowObj);
//scope.name += '!';
//scope.$apply();
});
}
};
});
SOLUTION BASED ON ANSWER:
angular.module('directives', ['opsimut']).
directive('flowclick', function() {
return {
link: function(e, elem, attr) {
// scope is the directive's scope,
// elem is a jquery lite (or jquery full) object for the directive root element.
// attr is a dictionary of attributes on the directive element.
elem.bind('click', function(e1) {
debugger;
alert(e.flowObj);
},e);
}
};
});

SOLUTION: Remove the whole scope property from your directive and everything should work as expected.
ALSO:
You'll need to rename the scope argument from this line:
elem.bind('click', function(scope) {
to something like:
elem.bind('click', function(e) {
because you are overwriting access to scope in your event handler by using the same name.
EXPLANATION:
The ng-repeat directive causes each of its clones to have their own new scope. Since directives on an element share scope by default, any other directives placed alongside the ng-repeat share its scope and have access to the current iteration's $scope variables. In other words, your custom directive already shares scope with ng-repeat and has access to flowObj by default.
The reason it didn't work when specifying a scope property on your custom directive is that this caused the directive to have its own isolate scope which did not share with ng-repeat and so you did not have access to variables on the clones' scopes.
