Use Js to dynamically add table examples written by myself_javascript skills

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 selectRow;//Page-level js variable, used to store the selected row so that it can be displayed in the pop-up window Row assignment

The project needs this function, and I have used several methods. I think this is better (after all, I spent a lot of time writing it, haha). I am not very proficient in js. I hope some friends can give me some advice. Help improve and improve. Failed work, not compatible with FF, bad!
