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.
I 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]*)$/
The pattern is already assumed to start at the beginning of the string
I am trying to use a string for a regular expression pattern. Here is a
test that I set up:
var s="^d{3}-d{3}-d{4}$";
var r=new RegExp();
r.compile(s);
var t="333-333-3333";
alert(r.test(t));
I have tried this with and without the "compile", and also adding the
"/..../" to the beginning and end of the string, but I always get "false".
Can you use a string to represent a pattern...in Javascript?
I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
Code:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
[code]....
I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.
Im trying to find if a particular html markup pattern (<ROD> ... </ROD>) within a string and if its found then replace it with another string.eg."This is my string and it might <ROD>PartNumber123</ROD> contain HTML markup"So in this case I want to replace "<ROD>PartNumber123</ROD>" with {0}. If there is no <ROD>...</ROD> then dont do anything.Im sure im doing this the wrong way, maybe a regular expression would be best.Although this works its not very clean and I just cant find the correct solution.
function parseData(data){
var r1 = data.indexOf("<ROD>",0);
var r2 = data.indexOf("</ROD>",0);

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.

alert(full);
var inside = (x.match(/(H:(.*))/)); // produces "(H:somestring),somestring" .. I only
want "somestring"
alert(inside);
</script>

All it's supposed to do is check whether or not "password" and "cpassword" match, if they don't it's supposed to put "Passwords do not match!" in the span "matchpass". I can't see anything wrong with the code and javascript is enabled in my brower. GetElementByName does not exist, so I switched it to getElementById and it works perfectly.
I 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.

Trying to check how many lines a div has and then alter another to match.
Found this code, but I'm not sure what to do [code]...
Look at Navigation and then look at Animated Menus as an example. When the grey animated menus (div.columnrt) takes up two lines (could be more), need the corresponding left div (div.columnleft) to be same number of lines, so that everything stays lined up. Each of these pairs sits inside of a li element.
What regular expression will match ANY string that has 10 digits in it?
View 24 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....
/*********************/

<INPUT onClick="fnTestNumberField()" id=Button1 type=button value="Test

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 RelatedIs there a way in a regexp to *not* match a fixed string value?

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 have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?
