javascript - In an Angular directive, how do you reapply an event listener after the event has been removed? -

-

this might result of me lacking knowledge in angular , if so, forgive me in advance if case.

in angular, suppose have directive bound element attribute.

<div my-directive></div>

in directive, have click event remove click event itself.

app.directive("mydirective", function() {    return {       link: function(scope, ele, attr, ctrl) {           ele.on("click", function() {               ele.off("click");               console.log("click event removed");           });       }    } });

i want set click event on same div directive again (let's after button clicked). how accomplish this?

you can use this- 

app.directive("mydirective", function() {    return {       link: function(scope, ele, attr, ctrl) {           ele.on("click", function() {               ele.unbind("click");               console.log("click event removed");               angular.element(ele).bind("click");           });        }    } });
