Js dynamically adds events and passes the parameter sample code

 
var tt=function(obj) 
{ 
return function() 
{ 
alert(obj.tagName); //An execution function that can be defined externally;
} 
} 
function addfunction() 
{ 
var bigobj=document.getElementById("mytable"); 
var rows =bigobj.rows; 
for(var j=0; j<rows.length; j++) 
{ 
for(var i=0;i<rows[j].cells.length;i++) 
{ 
rows[j].cells[i].attachEvent("onmousemove",tt(rows[j].cells[i])); 
//rows[j].cells[i].onmousemove = function(){ 
// tt(); 
//} 
} 
} 
} 

========== ======= compatible with FF and IE

 
function addEvent (o,c,h){ 
if(o.attachEvent){ 
o.attachEvent('on'+c,h); 
}else{ 
o.addEventListener(c,h,false); 
} 
return true;} 
var tt=function(obj) 
{ 
return function(){textChange(obj);} 
} 
addEvent(input1,"change",tt(input1)); 
function textChange(o) 
{ 

//do something 

} 

 with Jquery In one sentence  
$("input[type='text']").change( function() { 
//You can write some validation code here
});
