Question

How do I add an onclick event to a tag in HTML programmatically?

I want to be able to click a link, and have an onclick event attached to a Javascript function take effect on another tag.

Here is what I have so far:

var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount); 
var cell1 = row.insertCell(0); 
var element1 = document.createElement("input");
element1.type = "text";
element1.id="List["+num+"].id";
element1.name="List["+num+"].id";
element1.onclick="javascript:CalCal()";
cell1.appendChild(element1);

I want to call a Javascript function CalCal() on onClick event. Is this possible?

But keep in mind that addEventListener is supported in IE just from version 9. To support older versions of IE you could use something like that:

if (element1.addEventListener) {  // all browsers except IE before version 9
  element1.addEventListener("click", CalCal, false);
} else {
  if (element1.attachEvent) {   // IE before version 9
    element1.attachEvent("click", CalCal);
  }
}
