I have function code...
I want to remove all parameters, but first. I don't know what's wrong .
I would like to perform a regular expression on a string and if TRUE do something.
I have huge amounts of knowledge doing this in PHP but trying out javascript.
I'm having a bit of trouble with javascript... I'm searching for a string that starts with another string
code:
for (x in products ){
s = products[x].id.toString(10);
v = "/";
[Code]....
the variables are integers but since i'm searching for the beginning only i turned them into strings...
the problem occurs when I add the it turns out gibberish..
p.s. if there is a faster way to do it without turning the variables to string also would be great to know.
How can I get price from a string using regular expression ? Or by any other means .
Let's say. var str="Our shop receives only $. This shoe costs $200. We don't accept anything else then $"; ow could I retrieve '$200' from this above string. By any means.
I'm finishing my javascript form validator (only text fields for now) and here's one of the last things that's left.
I'm using class names of input elements as parameters for my validator. To find them i use Element.hasClassName(id, class) method from prototype library. I want to implement minlength parameter - so i grab a regexp tutorial and after a minute i had something like this minlength[[1-9][0-9]*], which finds minlength[1], minlength[666] and so on.
Great, but how to pass this as a paramter to hasClassName method, which requires string as a className?
My continuing problem with regular expressions! All I am trying to get is the expression must have at least 1 of these [a-z][0-9] in any order etc etc
RegExp(/[a-z][0-9]/)
didn't work

View 2 Replies View RelatedI have just spent a while searching how to use regular expression to strip out spaces in a string and replace them with ',' I don't seem to be getting anywhere and was hoping someone could explain how to do it.
So for example:

My string would end up looking like the following
Mystring = "A','b','c','d"
How can i validate string with alphanumeric, space, dash and dot in regular expression ?
View 1 Replies View RelatedI'm trying to perform a very simple validation of user input. I
want to verify that the user entered a six-digit string consisting
entirely of numbers. So anything from 000000 to 999999 is considered
valid. The problem that I'm having is getting the validation to work on
the entire string. In other words, 000000 is okay but 000000000000 is
also returning as a match. Here's a quick code block...I have something
along these lines....
/*********************/
<html>
<body>
<INPUT name="txtNumberField" type="text" id="txtNumberField">
<INPUT onClick="fnTestNumberField()" id=Button1 type=button value="Test
Number!" name=btnTest>
<script language=javascript>
function fnTestNumberField()
{
var sNumberValue = document.getElementById("txtNumberField").value;
if (sNumberValue.match(/A[0-9]{6}z/))
{
alert("match");
} else {
alert("no match");
}
}
</script>
</body>
</html>
/******************/
That is failing when I enter 123456 into the textbox. Why, though? I
know I can replace...
if (sNumberValue.match(/A[0-9]{6}z/))
....with something like...
if (sNumberValue.length == 6 && sNumberValue.match(/[0-9]{6}/))
....or I could assign a maxlength to the input box, of course. The thing
is, I really want to know WHY the regular expression isn't responding
as I'd expect. Is there a syntax error somewhere in the code?
<p> Howdy <p> expressed as a literal string that is passed to the setTimeout() function might look like this: setTimeout("document.getElementById('first').innerHTML = '<p>' + 'HOWDY' + '</p>';", 2000);
I guess you can't just put quotes around an expression like this: "'<p> HOWDY </p>;" So tags have to be isolated, but it get confusing with expressions like this, which I am not sure how to express as a string:
<p><h2 class="pos_left"> <img src="car1.jpg" name="slide" width="400" height="250" /> </h2> </p>
I wish I could change the " in there to ' and then just wrap the whole thing in double " This is what I came up with but it did not work: setTimeout("document.getElementById('first').innerHTML = '<p>' + '<h2' + 'class='pos_left'' + '>' + '<img' + 'src='car1.jpg'' + 'name='slide'' + 'width='400'' + 'height='250'' + '/>' + '</h2>' + '</p>';", 4000);
I have a search box. I need to remove all the special characters from the search term and then query it.-,?~!@#$%&*+-= all these characters.can anybody suggest a proper regular expression for this ? and the syntax for using it in javascript.my query is saved in var query;
View 7 Replies View RelatedI have got this xml file which has a background params which is <background>igmp:
{theme.background_video_ip}:1234</background>.
I have done the validation to check if the igmp protocol is used like this
if (clientSpecificData.background.substr(0, 7) == "igmp:") {
Right now I am trying to find out how I can use regular expressions to check whether a port number is used at the end.
Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string
View 14 Replies View RelatedI 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.
I want to know if there is a way to return ajax call as html value and not plain text, ie all html formatting will be displayed.

String returned from webform4.aspx is html formatted but jquery displayed it as plain text. Is that anyway to display it as html string ?

I've been searching and everything I find says that ${} should be able to handle arbitrary expressions, but there seems to be some syntax magic/intolerance going on here.
Does jQuery support a regular expression as a selector? eg: so I can get every element with a id beginning with "test"
