## Compare String With Numbers In Javascript

Jul 23, 2005

if (123 > 33) will return true

and

if ("123" > 33) will return true

So my question is, if the above behaviors are the same?? If string is
a number, and compare with another number, it will be the same behavior as compare 2 numbers?

In this case, it is comparing 2 strings that are numbers, so they are
string comparisons here. correct?

if ("123" > "33") will return true

In this case, "33a" is not a number, that's why when it compare with
another number, it always return false. correct?

if ("33a" > 33) will return false...

## Can JS Pick Up LANG Attrib's ..?

May 29, 2006

I'm new and naive at JS, but use a lot of modified JS snippets in web
design. I'm working on a six-language site for a client right now that has
a small nav bar at the bottom of each template-based page.

I've had success in previous projects, writing out language-specific nav-bar
code nested in a document.write statement; a unique .js file for each
language.

An idea that I came up with that would allow me to create a function that
would cover all languages was this: if javascript could somehow detect the
"lang" attribute of the <html> tag, it could automatically choose which
"langage" js file to reference for my nav bar.

Example, if my german nav bar was in a file, "/scripts/de.js" the function
would pick up "de" from the "lang" attrib in the <html> tag, assign it to a
variable, say "navlang", and render a document.write statement that would
"write" out my script source reference as such:

<script>
document.write('<script src="/scripts/' + navlang +'.js"></script>');
</script>

my problem is I'm not adept enough at JS to write a function that would grab
the LANG attrib of the page .

## Random Pick Of A Set Of Colors After A Time Interval?

Sep 27, 2011

I want to have a random change of the border and text color of certain DIVs (with a certian class) after a specific time interval. I managed to get a random color change after the time interval, but I'd like to just have a set of colors, which the random generator can choose from. So here's my code:

Code:

<script type="text/javascript">
var intervalId = setInterval(function() {
int i = (int)(Math.random() * 4);

[Code].....

So "i" can be a number from 0 to 3 and depending on this number, the variable "col" is a specific colorvalue which the border and text color will animate to. That was my thought, but something about the random color generator doesn't work
