I'm having troubles here with a piece of js code.


for example if you had some sort of setup like this


<html>
<script language = "javascript">

function checkForm(f){
alert (f.address:street.value);
return false;
}

</script>

<body>

<form onSubmit="return checkForm(this)">

<input type = "textBox" name = "address:street">
<input type = "submit" value = "Click Me">

</form>


</body>

</html>

this results in an error due to the, :

do you know if theres anyway of getting around this?

thanks in advance!

Sure, don't use :. Instead use an underscore, _.

well I would but it I can't due to the fact that the code was already weritten by someone else and many processes depend on the : to be there. So I can't take it out...but nice try,...

Reference it with the form elements array, like this:

alert (f.elements[0].value);

where 0 is the index of the element in the array.

Or, give it an id and reference it by that, like this:

alert (document.getElementById("theid").value);

hey thanks pyro, using id is good way,


I'm probably going to go that route.


do you know if there's a way to define it using special character preceding it?

kind of like if you want to embed a quotation in a string you'd use \"

or if you want to embed an amperstand you used &amp;

is there a way in js to do this with the colon?


thanks

Actually, this will work fine for you -- didn't think of it originally.

alert (f.elements["address:street"].value);
