Event Handling !

Recommended Posts

These scripts are not working .. I`ve crossed check them from Source code also. Please check.

 

Utilities.js

var U = {
$: function(id){
'use strict';
if(typeof id == 'string'){
return document.getElementById(id);
} // inner IF
}, // $() function




setText: function (id,message){
'use strict';
if((typeof id == 'string') && 
(typeof message == 'string')){
var output = this.$(id);
if (!output)return false;
if(output.textContent !== undefined){
output.textContent = message;
}// second inner IF
else { output.innerText = message;}
return true;
}// inner IF


},// SetText Function






addEvent : function(obj,type,fn){
'use strict';
if(obj && obj.addEventListener){
obj.addEventListener(type,fn,false);
}//inner IF
else if (obj && obj.attachEvent){
obj.attachEvent('on' + type, fn);
}// Else IF
},// addEvent Property








removeEvent : function(obj,type,fn){
'use strict';
if(obj && obj.removeEventListener){
obj.removeEventListener(type,fn,false);
}// inner IF
else if(obj && obj.detachEvent){
obj.detachEvent('on' + type, fn);
}// Else IF
}// RemoveEvent


};

Epoch.js

 

function updateDuration(){


'use strict';


var now = new Date();
var message = 'It has been ' + now.getDate();
message += ' seconds since epoch.(Mouseover to Update)';


U.setText('output', message);


}// Update Duration Function Ends Here


window.onload = function(){


'use strict';
U.addEvent(U.$('output'), 'mouseover', updateDuration);


updateDuration();


}; // Onload Function

 Epoch.html

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Mouse Events - Javascript</title>
</head>


<body>


<div id="output"></div>


<script src="utility.js"></script>
<script src="epoch.js"></script>
</body>
</html>

How are they not working? What is happening that shouldn't? What isn't happening that should? In what browser(s) have you tested this? You need to provide many more details here.
