========== 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)

$("input[type='text']").change( function() {
// You can write some verification code here
});
