problem setting a variable

jtrifts · August 8th, 2007, 02:05 PM

I have a strange problem where I can't set a variable or something else is going on.
here is a simple function I'm using

//the string I'm passing in is a url
//ie http://www.mywebsite.com/public/index.asp?x=2323

function validate(str){
alert(str); //this works
var strnew = str;
alert(strnew); //this works
alert("test" + strnew.length); //this doesn't work.I get an undefined

//but if I do something like this
var strnew1 = "http://www.mywebsite.com/public/index.asp?x=2323";
alert("test1" + strnew1.length); //this works
}

What am I missing here ?

I get test48 alerted as expected, perhaps some other piece of code is affecting the output? What does alert(strnew.length) show? Is there a chance some code has removed the length method?

I got the same result test48.

Although, It seems like there is no problem with the code..

You can modified the code as following:

<HTML>
<HEAD>
<script language="JavaScript">

function validate(str){
alert(str); //this works
strnew =new String(str);
alert(strnew); //this works
alert("test" + strnew.length); //this doesn't work.I get an undefined

//but if I do something like this
//var strnew1 = "http://www.mywebsite.com/public/index.asp?x=2323";
//alert("test1" + strnew1.length); //this works
}

validate("http://www.mywebsite.com/public/index.asp?x=2323")
</script>
</HEAD>
</HTML>

Thanks,

I tried adding a hard coded value to the html page
validate("http://www.mywebsite.com/public/index.asp?x=2323")

The javascript worked fine when passing in the hard coded value.
I did some other testing and it seems that no other javascript functions will work either when a value is passed in as shown below.

In my original code on the html page I was using
validate(window.location)

So I guess the next question is why doesn't validate(window.location) work ?

window.location is an object, try window.location.href. If you'd told the real story at the beginning...
