Custom ng-keypress, ng-keyup and ng-keydown directive in Angular js

In angular js sometimes we face an issue that is ng-keypress, ng-keyup and ng-keydown soetimes does  not work properly.
Here is the quick solution of this issue. You just have to write a small directive for this :

app.directive('zKeypress', function(){ 
 return {
     restrict: 'A',
     link: function(scope, elem, attr, ctrl) {
         elem.bind('keypress', function(){
             scope.$apply(function(s) {
                 s.$eval(attr.zKeyup);
             });
         });
     } }; 
});

Here is how you will apply this with tags:

<input type="text" z-keypress="foo()"/>  

You can change this keypress to keyup and keydown just to change one line :

  elem.bind('keypress', function(){

You can change this keypress with keyup and keydown

Remove last text from the string

Here is a simple and short method of resolving this issue:

var lastIndex = str.lastIndexOf(" ")

var str = str.substring(0, lastIndex);

 If you know the last text for example in my issue each string contains x in the last. I used str.lastIndexOf("x") for resolving my issue. You can customize it according to your requirement.
