Copy code The code is as follows:

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

========== Compatible with FF and IE writing
Copy code The code is as follows:

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

}

Use Jquery to do it in one sentence
$("input[type='text']").change( function() {
// You can write some verification code here
});
