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.

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,"");
