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();
return true;
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.

"Replace()" With Special Characters?

Aug 3, 2011

I have been using code such as

a=a.replace(/ /g,'');

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")?

function del(type, id, title) {

if (confirm("Are you sure you want to delete '" + title + "'"))
window.location.href = '' + type + '&id=' + id;
} else {
return false;

And finally the XHTML when I view source:

<a href='#' onClick='del(a,This is Another Test,38); return false;'>(Delete)</a>
... I'm getting absolutley no response. Ideas?
