Question

i try avoid explorer throws error in srcElement, it does not have this function.I have

function (event) {
    if (event.srcElement)
    {
        valueThis = event.srcElement.getAttribute("value");
    }
    else if(event.target)
      {
        valueThis = event.target.getAttribute("value");
     }
}

but it doesnt work because InternetExplorer throws error in e.srcElement

Answer 1

If you’re talking about IE<9, the event object is not passed to listener handler as the first argument. So

function(event)
{
    if(!event) alert("Dead");
}

will likely “dead” in IE.

A more common way to do this is:

function(e)
{
    e=e?e:window.event;
    if(e.target){/*...*/}
    else if(e.srcElement){/*...*/}
}
