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?
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...
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.
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.
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.
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.)
i have phone number on the page. Let's say 0208 123 45678 and i want to replace it with 0207 123 9999. Thing is, phone number is not in one type of tag, id or class.All i can tell you, it is somewhere throughout the body tag.
I have a textbox, and I want to search the contents of it and replace all instances of a certain word, and replace that word with something else. For the purposes of this it could be replacing "green" with "blue". Can someone please show me how to properly do this?
I am looking for a script that will find and replace all instances of a word in the page. how ever there might be more than one instance. I'm not that crash hot on javascript and all i have at the moment is:
This script should look for UNASSIGNED and replace it with nothing
HTML Code: function func1() { var str=document.getElementById("UNASSIGNED"); document.write(str.replace(/UNASSIGNED/g, "")); } window.onload=func1;
Also wanting another script that searches for a string via ID. if the id has SP.XXX <-- XXX being random numbers then i want it to find the and replace this repeating occurrence with a
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]
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.
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.
I am trying to replace all newline characters with <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine).
I have this script for replacing characters on form fields. I want to use it to remove letter accents. It is made to replace just one character, but I'm trying to modify it to replace many characters at once, but I'm not being able to get it to work correctly.
These are the characters that I would like to include code...
I'm just wandering, how can you stop the replace() function from replacing characters inside a word, such as, if I try to replace 'x' with 'and', then my string would go from 'example, x' to 'eandample, and'.
This is a makeshift sort function for a table. I want to replace a div contents with a javascript function call. It works fine if I define the individual case, but the general case doesn't work. The problem lies with the +divHold+ part. It never converges to the passed value on the 2nd iteration. This is my Div:
Is there a way to make one regex to replace a space with "Â " and a tab with "Â "?
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?
