I want to check a string if it contains certain letters.the string is Elephant and if i check it for the letter "e" i want it to display all the "e" letters.If i use the following code it always just displays the first "e". but i want to display all the "e".

So, for a simple little example of what I want to do...
REGISTRATION FORM
<br>
Desired Username: <input type="text" name="username">
[Code]....
I want to rig up something that will automatically check the values posted in "password" and "passwordcheck" before the form is submitted making sure that they match each other and give a little error message if they don't. Ideally, if they don't match it would also prevent the form from even being submitted. My knowledge of Javascript is pretty basic, in fact it primarily consists of what's covered under the "basic" category in [URL] Javascript tutorial, as well as a very modest understanding of form validation in the "advanced" section of the same site. So I haven't had much luck trying to accomplish this myself.
I don't need anything especially fancy (since if it were it would likely be beyond my comprehension at the moment) I just need it to be functional.
I'm trying to create a script where all the hyperlinks in a page will be replaced with a new set of coding before it. (e.g: a href="this.htm?http://www.google.com").
My code generates this change through a series of random numbers and only runs the script when "2" is the generated number (out of 12). Now, I only know how to replace all occurrences of "href" in all "a" tags, but there are times when I use Javascript to launch new windows or even javascript to navigate to the top of a page.
I tried to use a string match method to search for occurrences of "javascript:" and so forth, but I can't seem to get it working. Code:
How do I extract "somestring" only? I'm on IE7.
<script type="text/javascript">
var x = "(EVAL)(H:somestring)Some other Text here";
var full =(x.match(/(H:(.*?))/g)); // produces "(H:somestring)" as expected
alert(full);
var inside = (x.match(/(H:(.*))/)); // produces "(H:somestring),somestring" .. I only
want "somestring"
alert(inside);
</script>
How would i use a wildcard in String.match()? For example, I would like to see if a variable contains www.*.com, where the * can be replaced with anything. How could i go about doing that?
View 1 Replies View RelatedI need to find out if a string contains any of the following wildcard "@#!%^&*~". If exists, then the string is invalid. Instead of using indexOf each one of the wildcard, what else can do this easier?
View 2 Replies View RelatedI am trying to figure out how to set up my reg exp search so that the search
will only match on the exact word.
Here is the current problem code:
Word1 = "RealPlayer.exe"
Word2 = "Player.exe"
RegExp re = Word2;
if (re.Find(Word1))
{
bFound = TRUE;
}
Currently the bFound is set to TRUE since "Player.exe" is found within
"RealPlayer.exe". But I only want bFound to be TRUE is if the entire word
matches.

I am trying to do a pattern match and check something in a condition but cant get it to work. The first value changes and I need to check and do something if I get a hit on it.
Code:
var mydata = "?first=one&second=two&third=three";
if (mydata.indexOf("first") == "something")
{
alert("No Hit");
} else {
alert("Hit");
}
Basically I am trying to find out if first is equal to one in the mydata string. My above attempt is not working.
What regular expression will match ANY string that has 10 digits in it?
View 24 Replies View RelatedI wanted to only match in the middle of a string
I have a string = " sdfasf 23234"
I wanted to get the numbers like /([0-9]*)/
But this fails and returns nothing because the string begins with letters. Instead I had to do /[a-zA-Z ]*([0-9]*)/
If that's the case then, why do we bother with something like
/^[a-zA-Z]*([0-9]*)$/
The pattern is already assumed to start at the beginning of the string
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....
/*********************/

<INPUT name="txtNumberField" type="text" id="txtNumberField">
<INPUT onClick="fnTestNumberField()" id=Button1 type=button value="Test

<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");
}
}

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?
Is there way to only match on strings starting with the first characters input?For instance, if I have a list as such:[ 'Tamara','Amy']when I start to type 'Am', I only want to see "Amy" in the drop down list, not "Tamara".I feel like this should be an easy configuration option or easy mod, but alas, I could not find it.
View 1 Replies View RelatedI'm trying to check whether a string is all digits. This part is
easy:
function allDigits( str ) {
var foo=str.split( '' ); // better than charAt()?
for( var idx=0; idx < foo.length; idx++ ) {
if( !isDigit(foo[idx]) ) {
return false;
}
}
return true;
}
I'm not sure about how to implement isDigit(). Is this the best way?
function isDigit( s ) {
if( s.length > 1 ) {
return false;
}
var nums=﾿?'
return nums.indexOf(s) != -1;
}
I have the following piece of code in use on a vBulletin forum:
function sel(postid,username)
{
if (document.getSelection) {
var str = document.getSelection();
[Code].....
What this does is if the user highlights some text in a post and presses a button, it inserts the highlighted text into QUOTE tags within the Quick prely box.
This works fine...however, it doesn't check if the user has actually selected some text. Many users simply press the button thinking it will quote the entire post, when in fact it will simply insert some "blank" quote tags.
What would I need to add into this to check that some text has been selected, and return an alert if not?
Is there a way in a regexp to *not* match a fixed string value?
Using [^blah] gives matches to anything not containing *any* of letters
b,l,a and h. Whereas I want to match anything that does not containing
the exact string 'blah', i.e. *all* the letters.
Possible?
I am working on a script that seems impossible to work. I want to click on a link, and if the .text() is the same as a classname of a div, I want to do stuff with the div. The problem is that I can't imagine how to set up the if-state. Right now the script is like this:
$(document).ready(function(){
var filterTrig = $('#sortPort a').html();
$('#sortPort a').click(function() {
$('.listItem').each(function(){
if (!filterTrig == $(this).hasClass(filterTrig).html()){
$('listItem').addClass('test'); //later on, animations
}} return false; }); });
The script runs here: [URL]. I have turned off all other javascript to work only with this, if the site seems broken. The filterbox to the left will filter the div items listed to the right. All "boxes" in the list is a div with classname listItem + classes equal to the a.text() in the filters (leftbox). It is thoose divs I´m trying to animte with clicks.

I am wanting to have two arrays - oldArray & newArray.
I need a function which I can call so that it will look inside the
specified string ("theString") and replace each instance of each entry
of oldArray with the corresponding entry in new Array.
Example:
theString = "12345678";
oldArray = new Array("1","2","3");
newArray = new Array("One","Two","Three");
theString = theString.XXX(oldArray,newArray);
// theString = "OneTwoThree45678";

I have been working on this for a few hours and am frustrated
beyond all extent. I have tried to research this on the web as well
with no success. I am trying to match certain contents within a
wrapper div. So for example if the inside of the wrapper div was the
following:
<div id="wrapper">
<a href="#">a great link that contain text and symbols</a>
<div... </div>
<div... </div>
</div>
I would like to strip out all the internal div's. But because there
can be alot of internal div's, I figured it would be less processor
intensive to just match the first 'a' tag and repopulate the wrapper
div with the match. I am trying to use something like the following
regex:
re = /^<a(.+)</a>/;
with the following statment:
$temp = document.getElementById('wrapper').innerHTML.match (re);
but this is returning the entire contents of the wrapper div. I have
tried variations of the regex and either continue to get the entire
contents or null returns. Any help would greatly be appreciated.
BTW, I can't match to the first because the contents may be touching (ie ...</a><div>...).
