Make A Regex To Replace Diff. Characters With Diff. Things?
Jun 15, 2011
Is there a way to make one regex to replace a space with " " and a tab with " "?
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?
I have Declared same function and two diff javascript files and both files are included in HTML page and one more same function declared in HTML code too... So problem is that, which function will execute first, i mean function in either javascript or function in HTML Code?
I work in html and am minimally familiar with JS but am working with someone's code that uses form checkboxes to select options for hrefs in a decision tree. Given 5 options, selecting option1 takes you to page_x, option2 to page_y, etc. Users need option for selecting option1 AND option3, for example, to go to page_k.Is there a way in JS to take:
if(document.form1.A6.checked == true) { alert("A6 is selected")
I'm using this great plugin, but the prob for me is that all error messages have the same class added to them. due to the layout of my form, i need to be able to move some of the error messages around in diff ways. there is a way to add a diff error class to elements based on their id or class or whatever, but not sure how to do so.
I am trying to create a fixed crest at the top of my site that changes depending on where the viewer of the site scrolls to.
I found the following script/plugin on StackOverflow that works well for making one element fade in and fade out.
PART ONE:
function isScrolledIntoView(elem) { var docViewTop = $(window).scrollTop(); var docViewBottom = docViewTop + $(window).height(); var elemTop = $(elem).offset().top;
[Code].....
I then duplicated part two and changed the variables to make a different div appear in this position depending on where the viewer was in the site but it did not work past the first transition. see the following link to get a better idea what I am trying to achieve.

Is there any way I can adjust the script to make it work with multiple transitions?
I'm trying to make selected text appear / disappear depending on what the user clicks on. It works perfectly (as far as i can tell) in firefox, but in IE i get "Could not get the display property. Invalid argument". the strange thing is, it will make things disappear, but not show. I'm trying to change the display from 'none' to 'table-row' because that's the only thing that would display properly in firefox. here is the applicable [code]...
We have been using the following js/regex to find and replace all non-alphanumeric characters apart from - and + outputString = outputString.replace(/[^w|^+|^-]*/g, "");
However it doesn't work entirely - it doesn't replace the ^ and | characters. I can't help but wonder if this is something to do with the ^ and | being used as meta-characters in the regex itself.
I've tried switching to use [W|^+|^-], but that replaces the - and +. I thought that possibly a lookahead assertion may be the answer, but I'm not very sure how to implement them.
I was hoping that someone could give me a hand with a regex quetsion. I'm quite new to it all, but managed to get things working pretty much how I would like them except for allowing special characters such etc.
I'm writing a form validation function and would like to verify that a field only contains alphanumeric characters. How should I structure that statement? the following seems logical but doesn't work;
I have a little Ajax script and I'm trying to remove some CSS elements from a DIV tag and I'm have a bit of trouble with the Regex. Right now I'm trying to remove the z-index attribute. It can look something like any of these:
What is the best way to white list a set of allowable characters using regex or replace? I understand it is safer to whitelist than to blacklist, but am not sure how to go about it.
I have some contents on my page that are displayed on click or hover.Therefore, initially they are hidden using the hide() method.
They work fine as intended.
But if it is a slow computer, you can see them on the screen for a second or two before they disappear. Or if the user refreshes the page - you get the same thing happen. How can I prevent this?
I am writing a script that will replace the src of an image when the user hovers over it. I am using jquery and regex to accomplish this and have tested it on my local server but the src of the images on the live server is different and uses a non-relative path. Here is my code
$(document).ready(function() { $("img.imagefield").mouseover(function() { var regex = "^(http|https|ftp)://[a-zA-Z0-9-.]+.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/sites/all/files/[a-zA-Z]*"; var src = $(this).attr("src").match(regex) + "_silly"; [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 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?
to eliminate spaces in a string, as well as converting things like ";," to ";" in strings.Several instances of these replacements will have to occur in the strings.Unfortunately, I cannot make it work for converting two commas into one or for eliminating line breaks. Does anyone know how to do this (preferably without using "while")?
The encoded html part is simply a link [URL] The code works fine so far on all browsers. But the problem is that it redirects wrongly.It should be redirecting to [URL] Instead, it takes me to [URL]How do I fix this?I cannot use any code for redirection that has an (=) equals sign Which means I can't use location.href='http://google.com'
