Compatibility function to replace window.event.srcElement effect_javascript skills

Copy code The code is as follows:

function getEvent()
{
var i = 0 ;
if(document.all){
return window.event;
}

func = getEvent.caller;
while(func != null)
{
var arg0 = func.arguments[0];
if(arg0)
{
if(arg0.constructor == MouseEvent)
{
return arg0;
}
}
func = func.caller;
}
return null;
}

If you want to make a reference in the function, you must pass the parameter e before you can wait:

Copy code The code is as follows:

function buttonOver(e)
{
e = getEvent( );
var obj = e.srcElement || e.target;
if (obj.runtimeStyle){
obj.runtimeStyle.cssText = "background-color:#FFFFFF";
}
else
obj.style.background = "#FFFFFF";
}
