Aug 21, 2011IE 7 is throwing a JS error and I can't figure out why (probably because I am new to JS). FF and IE8 do not throw any JS errors. The JS error I get looks like this:
Line: 42
Char: 3
Error: Expected identifier, string or number
Code: 0

I'm not sure which JS file this error file is referencing.

Sep 9, 2006Now I need to convert a number(decimal) into a hex.string. I want to pass my blurit() two colors and have it start at color one and step its way to color two based on a determined step.

Convert A Number To A String?
Apr 3, 2010I'm trying to write code to swap images in a list. It's going to be a star rating control that highlights stars as you hover over a star. each image in the list has an onmouseover="highlight(this)" function and a unique id of 1 - 10.
Code:
function highlight(star) {
var num = Number(star.id);
for (i = 0; i < num; i++)
[Code].....
I'm trying to convert the number 'i' used by the for loop to a string so it can be used by the getElementById() method to select the stars to be highlighted. But my intellisense is telling me there is a problem with that line. I tried
var id = String(i+1);
but this didn't work either.
what have I gotten wrong?

Finding A Number In String - RegExp
Aug 13, 2005How can I check if a number exists by itself in this string by using
the RegExp object?
var mystring = "11,111,01,011";
var match = "1";
var re = new RegExp( match );
var isFound = re.test( mystring ) );
Running this code returns 'true' which is not what I want since number
one doesn't exist by itself. I need to use the "match" variable since
it will change depending on user input.
I can only get it to work without variables in the expression. E.g.
var re = new RegExp( /1/ );
Why Does 1+1 Equal 11? Or How Do I Convert A String To A Number?
Sep 2, 2006Javascript variables are loosely typed: the conversion between a
string and a number happens automatically. Since plus (+) is also
used as in string concatenation, `` Ƈ' + 1 '' is equal to `` ཇ' '': the
String deciding what + does. To overcome this, first convert the
string to a number. For example:

RegExps : Grab Number Inside Of String
Oct 18, 2007I'm looking for a way to grab a number from a string, although this number
is not at either end of the string.
Here is the string in question: var el = "v4Function_Name('argument3')"
Here is a substring that returns the number ( the 3 ) successfully...
var number = el.substring(el.lastIndexOf("ent")+3,el.length-2);
Seems very ineffecient to do it this way, and better to find a lean elegant
way using replace(); How does one go about getting a value inside of a
string with regular expressions? .. or is there a better way?
Here are a couple of the many expressions I have failed with...
var pat = /^[^ent][0-9]*$"/;
var pat = /v4Function_Name('argument([^0-9]+)'/;
var number = el.replace(pat,"");

Generate And Add An Unique Identifier To The Email
May 5, 2011I am developing a html ordering system that does not use a database but sends the data via email. To differentiate between two orders I would like to generate and add an unique identifier to the email. One approach I have seen is using data object to generate an unique id:
function uniqid()
{
var newDate = new Date;
return newDate.getTime();
}
This is not guaranteed to be unique as two people can send their request at the exact same time. One question pops up, the data being generated, is this local or utc time? Also, the number being generated in this situation is quite big and not so easy to differentiate two orders for a human. Ideally I would like to generate a global sequence starting at 1 and incrementing by one for each user that clicks on the order button regardless of timing, timezone etc. Is this possible given the constraints given at the start of the post?
