consider this code below:
var toremove = "some";
var tolook ="I am looking for some other text in this string toremove";
if i do this:
tolook = tolook.replace(/toremove/gi,'');
will to look replace the text inside the toremove variable, or will it
just replace the variable name?
I am facing a problem in passing replace() function as an argument in user defined java function.
intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '' to '\'
I am posting my javascript function here:
<a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\/g,"\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a>
function OpenDocPreview(url, docname) {
alert('message from search base : ' + url + ' ' + docname);
}

I see the use of Javascript replace all over the web. What are all the
character sequences? (sorry I am a bit of a newbie at this).
i.value.replace(/[^d]+/g, '');
I understand that /g is global and /i is case sensitive, but what are
the rest? I am asking because I am trying to write a function that
takes an input and replaces everything but numbers and a . (for decimal
numbers).
I want to remove from string a <span> tag, but with leave the value of
that tag.
I have that code:
theExp = new RegExp("<span>", "g");
txt = txt.replace(theExp, "");
theExp1 = new RegExp("</span>", "g");
txt = txt.replace(theExp1, "");
and this works only with FF,
With IE it doesn't remove the tag.
With Opera the same
I don't think this is "do-able" but thought I'd better check. Say I
want to replace certain names in some source code as long as they are
not properties (dot properties) of objects. I could use a regular
expression like:
rx = /(?:(.)|)(?:name1|name2|name3)/g;
map = [];
map["name1"] = "a";
map["name2"] = "b";
map["name3"] = "c";
source = source.replace(rx, function ($0, $1) {return $1?
$0:map[$0]});
Dot properties like .name1 are not replaced by anything new and they
need to be "skipped" over by this regular expression but other name1
identifiers need replacement with "a".
One problem with this approach is that dot properties like .name1 are
replaced by themselves and this is just unnecessary work. Something
like a "false" return to skip replacement would be nice but the
following doesn't work.
source = source.replace(rx, function ($0, $1) {return $1?
false:map[$0]});
There are other ways to get around this by using something else
besides replace() but I wanted to see if it could be done with the
replace() method.
I've a function like this: Code:
function submit_msg() {
if (egsd.value == 'yes') {
write_msg("<b>" + chatkeo.value + " : " + chatmsg.value + "</b><br />");
} else {
write_msg(chatkeo.value + " : " + chatmsg.value + "<br />");
}
chatmsg.value="";
}
Now I need to do some string replace in chatmsg.value, ie, I need to look for some piece of text in chatmsg.value, and in case they are present (there may be multiple occurences of the same), to replace them with something else. This is what I got by doing a google search: Code:
function replaceAll( str, from, to ) {
var idx = str.indexOf( from );
while ( idx > -1 ) {
str = str.replace( from, to );
idx = str.indexOf( from );
}
return str;}
chatmsg.value = replaceAll( chatmsg.value, "string to replace", "new string" );
And I place this second function just above the previous one. But it's not working. Any help friends?
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:
z-index: 1000;
z-index: 0;
z-index: 75;
etc...
Here's what I'm using right now:
document.getElementById('right_column').innerHTML.replace(/z-index: [0-9]; /gi, "replaced"));
It replaces z-index: 0; just fine but I can't find the correct modifiers to make it work for 2, 3 or 4 digit z-indexes.
I was debugging my code looking for a loop. So in the process I added a confirm request and if the user clicked cancel I coded location.replace("Kill.html"). Problem was that the JAVASCRIPT continued to run until either it finished or I used the Task Manager to end the session. :( There3 was a small difference in browsers: Firefox put up the new screen while continuing to run the JAVASCRIPT while IE didn't put up the new screen until after the JAVASCRIPT was finished. I could tell the JAVASCRIPT was still running because the confirm messages kept popping up.
View 5 Replies View RelatedCan anyone recommend a good Javascript cross-browser string replace method? On both PC Mozilla Firefox and IE 6, I tried this

I have some jQuery which I used on a site a couple of years ago. It basically loads some content into a DIV, which can be rotated using a .click function.I'd like to use the same code again, and I have got it working, but instead of having to click a link with a specific ID, I'd like it to automatically run every 4 seconds.
Here is my code:
var $j = jQuery.noConflict();
$j(function(){
var offset = 5;

and here is my HTML to trigger the function:
<div id="postContainer">... loading ...</div>
<a href="#" id="another">show another</a></span>
replace that .click function to run automatically every 4 seconds.

I've been using a hidden iframe for remote server scripting - how i've been doing it is that a load(); function changes the src component of the iframe with $_GET variables to pass to PHP:
this.load = function () {
this.iframe.src = this.file + "?action=load&gid=" + this.gid + "&last_modified=" + this.last_modified;
}
The frame itself then has an "onload" function that calls a doLoad(); function that handles receipt of any information back from the server. declared this way:
<iframe id="loader" onload="loader.doLoad();" style="width:0px;height:0px;border:none;"></iframe>
The trouble with this as you may guess is that the page was reloading every time src was changed and the history list of the browser was messed up. So I did some research and came up with this method that solves that problem:
this.load = function () {
//this.iframe.src = '';
this.iframe.contentWindow.document.location.replace(this.file + "?action=load&gid=" + this.gid + "&last_modified=" + this.last_modified);
}
Which is great, but now onload doesn't call!
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'.

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');

Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.
I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.
The error is: Error: theFrame has no properties
Line: 8
The line that the javascript console is showing an error for is in italics.
code from page:
<html>
<head>
<script type="text/javascript">
var defaultCols="100px,*";
var hiddenCols="0px,*";
function ShowHideMenu(){
theFrame = document.getElementById("framed");
if(theFrame.cols == defaultCols) theFrame.cols=hiddenCols;
else theFrame.cols=defaultCols;
}
