Get the current field name
I called below function on the body and what I want is when I press anything in textbox it will alert me the name of the textbox and I want to check the name and then execute something. Checking name is working great in FF and not in IE. Thanks
<body bgcolor="#F2F2F2" OnKeyPress="return getFiel开发者_高级运维dName(event);">
...
function getFieldName(e) {
e = e || window.event;
var key = e.keyCode || e.which,
target = e.target || e.srcElement;
}
This works but target.name is not trappable in IE
for eg:
if (target.name == 'one') {
//we can reach here is FF and Not in IE
}
You can know which element triggered the event by looking the e.target property (or e.srcElement for IE):
function getFieldName(e) {
e = e || window.event;
var key = e.keyCode || e.which,
target = e.target || e.srcElement;
alert(target.name);
return (key != 13);
}
Check the above example here.
