Replace() Double Characters - Instances Of "zz" With 'Z' Doesn't Work

Dec 18, 2010

This is driving me nuts :) I need to replace all instances of "zz" with 'Z'. I can easily replace other strings such as a = a.replace(/mickeymouse/, "Z"); but a = a.replace(/zz/, "Z"); doesn't work. Must be a double characer thing?

Replace Doesn't Work / What To Do?

Aug 25, 2011

I've got a form textarea on my site, which after being submitted is stripped by my php file.

Then my javascript kicks in and does some analysis of the entered text. However everytime the user entered a hard return within the textarea my javascript gives me an error 'tekenreeks niet afgesloten' which means something like 'string is not closed'.

Therefore I decided to replace all occurences of chr(10) and chr(13) with ok2 (just some random characters), I did this with php which worked fine, and I didn't get the javascript error.

However I need to reshow the entered text (original) to the user, so I need to restore the old values. I tried result.waarde.replace('ok2', 'chr(13)'); but it doesn't work, as it still displays ok2.

I'm no expert in javascript, but how can I replace those characters by the hard returns?

Oh yeah I'll show some more coding, perhaps the error can be found there code...

Onkeypress Doesn't Work For Japanese , Chinese , Korean / Detect Those Characters?

Jan 27, 2009

If I type characters using a Chinese text input (one where I type 2-3 latin characters for each Chinese symbol) there is no onkeypress or onkeydown event triggered. Any idea how to detect those characters please? I need to catch those chars in JS to pass them to a plug-in.

Text Replace Problem, Doesn' Work In IE

Jul 27, 2006

After the HTML page finishes loading, I want the JavaScript code to go tthrough all the text and replace some words. The following code works in FF

x=document.body.innerHTML.replace(/CC/gi,'Credit Card');
document.body.innerHTML = x;

but refuses to work in IE. It gives a "Operation Aborted" message and does not even render the orginal HTML. Any suggestions? .. Maybe I am going wrong about the entire thing, all i want is to alter text (not tags) on the page using JavaScript.

Regular Expression - Enter A String That Is 2 - 20 Characters Long And Only Has Letters Doesn't Work

Jun 28, 2010

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.

JS Character Counter To 'double' Certain Characters?

Mar 14, 2010

I'm trying to make this tool for some fellow librarians who answer questions via text messaging. As you see beneath that page's text box, the catch is that the PC-to-SMS client treats the forward slash as two characters.

I'd like if possible for the JavaScript character counter to recognize slashes and automatically add 'two' to the character count, instead of just one, for each forward slash.

(BTW the reason for 155 instead of 160 is that the client adds a shortcode to our outgoing texts.)

JQuery :: Use .replaceWith To Target And Replace All Instances Of Simple Text String?

May 11, 2011

I am working on a site that has an acronym in the content that require a registered trademark symbol. This content is added via a CMS. I am currently having problems with the special character sticking when entered via the CMS textfield (it turns into a ? if the CMS page is edited and resaved), which brings me to my question:I would like to just enter the basic acronym via the CMS, like so: ACRONYM and then use the JQuery .replaceWith feathure to add the registered trademark to the ACRONYM dynamically so it will return: ACRONYM ® in place of all instances of ACRONYM that exist within a container div that has a lot of other content like so.I tried the following example and it worked in my webpage, but when I tried to change the code to replace just a text string instead of the p tag it did not work. I did not see an example of this in the documentation. So is this possible with .replaceWith and how would I fashion the code to look for the ACRONYM only? or is there some other method that is better suited fro what I am trying to do? [code]

Replace Whitespace Characters In String

Oct 12, 2005

I have a JavaScript string. I want to replace all consecutive
occurrences of whitespace characters like spaces, tabs, newlines, and
form feeds with another string.

For example, say I have a string consisting of:

-- 3 spaces
-- The characters "hello"
-- 2 newline (
) characters
-- The characters "goodbye"
-- 5 spaces

After applying some sort of regular expression to replace consecutive
occurrences of whitespace chars with the string "X", the string should
consist of the following:

-- The character "X"
-- The characters "hello"
-- The character "X"
-- The characters "goodbye"
-- The character "X"

How could I do this using regular expressions? I'm quite familiar with
JavaScript but don't know anything about regular expressions or using
them in JavaScript, so please show me step-by-step how it's done.

JQuery :: Possible To Replace String Characters?

Aug 4, 2009

I am running a search on my web site which uses jQuery to take the search terms and build up a URL based on them. For example, if someone searches for "chair" my URL will be appended with /chair/. However, if someone searches for something which is two words, for example "chair covers" I need the space in between to be replaced by a "+" sign so the URL will now be appended with /chair+covers/ I'm not sure if it is possible to string replace in jQuery?

Here is my current code:
function sendSearchInput(whichelement,hiddeninput,formid) {
hval = $("#"+hiddeninput).val();
$("#"+formid).submit(function() {
if ($("input:#"+whichelement).val() != hval) {
var searchval = $("#"+whichelement).val().toLowerCase();
$("#"+formid).attr("action","retail/search/"+searchval+"/");
return true;
}
$("input:#"+whichelement).focus();
return false;
});}

This will basically check that the form is not the default value (specified in the hidden field "hval") and then change the search term to lowercase and append the URK using "attr". I have tried a couple of methods including
var test = searchval.text().replace(' ','+');
And then trying to alert "test" to check it but the function just simply doesn't work.

AJAX :: Cross-browsing Request Work Around - Every Browser Doesn't Work ?

The "Permission denied" cross site issue.

I have to check from my external domain if a service is running on localhost:8080 of a local machine.

I'm using XMLHttpRequest to do it.

I'm checking a local-web-server, not a file.

Every browser doesn't work, but Firefox. So I'm looking for a work-aorund.

An iframe? a flash swf? an applet java? HTA applications?

A side question is, why does FF work? Because it's a local-web-server?

Currently I'm using two regex's with string.replace( ... ).replace( ... ), but that means it has to run through the string twice. Any way to do what I want in one regex?
