Searching For String Starting With Expression?
Nov 29, 2009
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.

Is there a quick jQuery one liner to return (as an array) all class names that start with "{insert_string_here}"The equivalent of the following:
Code:
var response = $( "*[class^='arete']");
var myClassArray = [];
for( var ix=0; ix < response.length; ix++)
[code]....

I am trying to search an array for a string and then if it is found alert it. I have found examples of how to iterate the array and how to use .IndexOf to return a true false statement as to whether the array includes the string, but i don't know what to do after that and how to display the string if its found.

I am working on a little project where I have a form that allows a user to input a sentence that will be sorted alphabetically when they click sort. The result should be displayed in the Output box at the bottom. Then They should be able to enter a string that will be search from the previous sentence entered and that search will display in the output as well. Then last they should be able to enter in a replacement string; however, I have not done much reading on that so I am completely clueless there.
I thought I would start with the small stuff and last I would work on the replacement string. So I have the form done, but I seem to be struggling with the functions. I think I should use aname.sort to sort the words in ABC order. I am wondering if I am just completely off on how I am trying to do all of this. Any tips would be great, just to maybe point me in the right direction. Code:

How would one search for more than one one simultaneously? I have this function:
var flix = ["Any items left unattended on this table" , "Hello, World"];
function Multiwords(s){
var a = flix[0].toLowerCase();
var b = s.toLowerCase();
var result = a.indexOf(b)
if (result >= 0)
[Code]...
It's pretty basic, it just searches through the first index of var flix and tells me if the parameter (s) is 'found' or 'not found'. I made it not to be case sensitive. However, how would I search for multiple words for example:
Multiwords("ANY items This") and if any combination of 'ANY' or 'items' or 'This' is found, i still get my alert message of 'Found'?

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?

I 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:
Mystring = "a b c d"
My string would end up looking like the following
Mystring = "A','b','c','d"

I'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 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

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.
