Javascript error : Message: Expected ')'

Question

I am getting a javascript error below, but I can't seem to find the problem:

*Message: Expected ')' Line: 431 Char: 220 Code: 0

URI: http://mywebsite/CustomerLogin.aspx*

Line 431 is this javascript line:

<script language='Javascript'>
    var varDateNow = new Date();
    var varTimeNow = varDateNow.getTime();
    var varAlertTime = document.getElementById('cphTopContent_AlertTime').value;
    if(varTimeNow - varAlertTime < 1500)
        {alert('2' values you entered were not valid:\n\nLog In -  This value requires at least 6 characters. \nPassword -  This value requires at least 4 characters. \n');}
</script>

What is causing the javascript error?

I highly recommend using a better text editor to write your javascript. — jbabey

You have a missing open quote. Try taking out the close quote after the 2 in the alert. Here's what happened behind the scenes: Since you closed the quotes after the 2, you're actually opening a new set of quotes at the end of the line after the \n. So the compiler interprets everything following that point as a string, and thus it never finds the closing parenthesis.

This doesn't explain to the OP why he was getting the error he was getting. He missed it the first time, what makes you think he'll notice the difference here?

{alert('2' values you entered were not valid:\n\nLog In -  This value requires at least 6 characters. \nPassword -  This value requires at least 4 characters. \n');}

Should be

{ alert("2 values you entered were not valid:\n\nLog In -  This valid requires at least 6 characters.\nPassword -  This value requires at least 4 charactersn\n"); }

You messed up a few quotes, so the bracket that should end alert() was actually a string.

Parenthesis if you're in the States, bracket if you're a UK guy like me :) Over here parenthesis can refer to commas, like this, brackets (these things), or dashes - pretty much two hyphens - and all can be used, though I think commas are preferred.

The alert message must be a string. Hence, after the '2', it just doesn't understand what you want to do with all the chars and stuff.

alert("blah blah '2' more blah and blah " + variableSomething + "finalBlah");

not the reason for the error he got, the reason for the error he got is the mismatch of quotes, leading to an unterminated string.
