i am using angular1's component design to build this application. i have made a directive with does the ripple effect on a button when user clicks on it. this is a common behaviour so i have taken it in the directive. now i want to add another event listener to the same button from the component controllers $postLink() hook which causes directive event listener to fail in execution.
how to solve this issue. i want both events listened.
below is my ripple effect directive. i am using commonjs to load the modules so don't be bothered by that.
var app=require('../../../../Development/Assets/Js/appConfig');
app.directive('wave',waveConig);
waveConig.$inject=['$compile','$timeout'];
function waveConig($compile,$timeout){
return{
restrict:'A',
link:waveLink
};
function waveLink(scope,elem,attr){
var waveColor = attr.color;
elem.unbind('mousedown').bind('mousedown', function (ev) {
var el = elem[0].getBoundingClientRect();
var top = el.top;
var left = el.left;
var mX = ev.clientX - left;
var mY = ev.clientY - top;
var height = elem[0].clientHeight;
var rippler = angular.element('<div/>').addClass('wave');
rippler.css({
top: mY + 'px',
left: mX + 'px',
height: (height / 2) + 'px',
width: (height / 2) + 'px',
});
if (waveColor !== undefined || waveColor !== "") {
rippler.css('background-color', waveColor);
}
angular.element(elem).append(rippler);
$compile(elem.contents())(scope);
$timeout(function () {
angular.element(rippler).remove();
}, 500);
});
}
}
below is my component controller code.
verifyCtr.$inject=['$element','verifyService','$scope'];
function verifyCtr($element,verifyService,$scope){
console.log('verify component is up and working');
var $this=this;
var serviceObj={
baseUrlType:'recommender',
url:'https://httpbin.org/ip',
method:1,
data:{}
};
$this.$onInit=function(){
verifyService.getData(serviceObj,{
success:function(status,message,data){
$this.data=data;
},
error:function(status,message){
alert(status,'\n',message);
}
});
};
$this.$onChanges=function(changes){};
$this.$postLink=function(){
angular.element(document.querySelector('.addNewTag')).bind('click',function(){
console.log('hi there you clicked this btn');
});
};
$this.$onDestroy=function(){
angular.element(document.querySelector('.addNewTag')).unbind('click');
var removeListener=$scope.$on('someEvent',function(ev){});
removeListener();
};
}module.exports=verifyCtr;
when i run it. the component click event-listener is fired. but the directive fails to execute. i don't know whats causing this issue and i want both of them to work.
it took a while to figure it out.
document.querySelector('.class-name') ;
returns a array of html elements. and
angular.element(elem).bind()
works on one single angular element. so i had to use a unique way of identifying the element i,e by the Id. so what i did was
angular.element(document.querySelector('#id')).bind();
there is other ways of doing it by the classname also . we can itreate over the array and get our element and bind the event to it.
