I've got an image that when it's loaded it initiates a function that runs the first block of code below which checks if the image is part of a series. If it is it searches for the number in the source file. If it's the first image (which doesn't have a number) it sets the matches to 0
Code:
var regex = /(d+)/;
matches = regex.exec(_this.source);//'files/images/transworld mag.jpg'

I am not able to calculate the offsetwidth of the element which contains extra space in between the characters.for ex. if the element contains "A A" as a innerHTML value - if we calculate offsetwidth as 29 and also if the element contains "A A" value again I am getting the same offsetwidth as 29.While calculating the offsetwidth it is not calculating the empty space.May I know how to calculate the offsetwidth with the empty space because I need to insert the ellipsis (...) if it exceeds original width?

I found this regular expression on the internet and it works fine when I test it in various validators on the web.
Code:
^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$
It's purpose is to check for valid date and allows formats mm/dd/yyyy, m/dd/yyyy, mm/d/yyyy or m/d/yyyy.
When I try it with the code below it always returns null.
Code:
function isValidDate(/* String */ p1_date) {
var x = "^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$";

This is my first serious attempt at using a regular expression.My first name field should allow alpha characters only [A-Za-z], but it seems to be testing for the presence of 1 alpha character. If one is found in the string then anything else is allowed.Bob returns valid which is what I need.Bob1 returns valid but should NOT be valid..1 returns valid not valid which is what I need.My code.
function isValidFirstName(p1_firstName) {

I have the following code:
var str = "/dev/filler/test0/";
var patt = new RegExp("/test0/$");
var result = patt.exec(str);
document.write(result);
which returns: /test0/
in the var patt line I would like to replace the hardcoded test0 string with an expression that matches any characters between the two forward slashes. I have tried with little success.
am in need of escaping the regular expression special characters like '/', '.', '*', '+', '?', '|','(', ')', '[', ']', '{', '}', '\'.I have try with this by the following javascript but i can not achieve that.
RegExp.escape=function(str)
{
if (!arguments.callee.sRE) {

String must be minimum 6 charcters long and can only contain A-Z, a-z and 0-9 ....
View 2 Replies View RelatedAttempting to use javascript's regular expression methods to match a
particular lab number and building which would then be copied to a pair
of textfields, I found that general matching characters needing a
backslash were not recoginized. The following adapted code that finds
a two-button radio selection shows my problem:
function labstat(){
for (i=1; i<3; i++){
if(document.tester.rm_mod[i-1].checked){
var lb = document.tester.elements["lab"+(i)].value;//either
214 or 215*
var bld = document.tester.bldg.value;
if(/*/.test(lb)){ //error:Undetermined comment
// if(/*/.test(lb)){ //error:Syntax error
// if(/5/.test(lb)){ //works to match only 215*
// if(/5*/.test(lb)){ //true for all
// if(/ddd/.test(lb)){ //false for all
document.tester.room1.value = lb;
document.tester.bldg1.value = bld;
}
}
}
It appears that the escaped characters are not recognized, whichever
form of the method is used, i.e var re = /*/; // or = new
RegExp("*");
if(re.test(lb)){

With the --.match(__) method I have the same problem.
I wanted to try creating a basic expression first. I want someone to enter a string that is 2 - 20 characters long and only has letters. This is what I use so far, and it doesn't work, nothing happens at all when I run it.
Code:
// Check for a valid name.
var namePattern = new RegExp("/^[a-zA-Z]{2,20}$/");
if (namePattern.test(name))
{
window.alert("Invalid");
}
name comes from a input box I display on screen. Also, I would like to update the expression so that there can be one space in the string, but it cannot be at the beginning or end. So this string is like a persons name. Bob is OK, Bob Smith is also OK. Edit: Actually, it is doing something but its always coming back invalid.

Since the header is custom, and doesn't exist in any specification whatsoever, then would this still be valid?

I have a script that I am trying to get working in IE. It works great in Firefox, but will only work one time in IE.
The idea is that the user is presented with a field. As soon as the user types in the field the script adds a new field under it. To keep from adding more than one field there is a variable called probURLnumKeep that gets incremented only if the field being typed in is the last field created. Code:
