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 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:
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[$0]});
There are other ways to get around this by using something else besides replace() but I wanted to see if it could be done with the replace() method.
Now I need to do some string replace in chatmsg.value, ie, I need to look for some piece of text in chatmsg.value, and in case they are present (there may be multiple occurences of the same), to replace them with something else. This is what I got by doing a google search: Code:
function replaceAll( str, from, to ) { var idx = str.indexOf( from );
while ( idx > -1 ) { str = str.replace( from, to ); idx = str.indexOf( from ); } return str;}
chatmsg.value = replaceAll( chatmsg.value, "string to replace", "new string" ); And I place this second function just above the previous one. But it's not working. Any help friends?
I have a little Ajax script and I'm trying to remove some CSS elements from a DIV tag and I'm have a bit of trouble with the Regex. Right now I'm trying to remove the z-index attribute. It can look something like any of these:
I was debugging my code looking for a loop. So in the process I added a confirm request and if the user clicked cancel I coded location.replace("Kill.html"). Problem was that the JAVASCRIPT continued to run until either it finished or I used the Task Manager to end the session. :( There3 was a small difference in browsers: Firefox put up the new screen while continuing to run the JAVASCRIPT while IE didn't put up the new screen until after the JAVASCRIPT was finished. I could tell the JAVASCRIPT was still running because the confirm messages kept popping up.
I'll probably be laughed at for this attempt of coding, but all I am trying to do is read an input field, remove the "$" and write the new value in a different input field.
function convert_action (form){ var input1=form.input_field1.value; var clean=input1.replace(/$/, '');
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;
I've written a function to format a number. It strips dollar signs and commas, converts to a number, and sets the number to two decimal places.However, I get the error message "amountNum is undefined". It occurs right where I use the replace command.[code]I am calling the function with this line of code:[code]
is it possible to combine the the following functions with each other in an array for example and if so, would someone be kind enough to show me how. the reasons are 1. to see if it is at all possible and 2. to learn so that I can combine further possibilities in the future. the first script compares user keywords from search mashines and the second replaces certain strings/paterns with others.
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:
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:
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:
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 trying to make a function to strip a string of all slashes. Initially I had:
Code: String.prototype.stripSlashes = function () { return this.replace('\',''); }
and that worked fine except it only replaced the first slash (which it apparently is supposed to do). So i read up about global replacements but cant seem to get the right combination of /s and s. This is what i have at the moment:
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>');
I have a HTML page and 2 Javascript files. All files are in the same directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the formatting):
index.html ---------- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Test</title> <SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1" SRC="showimage.js"> </SCRIPT> </head>
<body> Click the house<BR> <A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG SRC="house1thumb.jpg"></A> </body> </html>
showimage.js ------------ function newWindow1(pic,sitename) {
resizewindow.js --------------- function resizewindow() { // Do resizing here. // Right now this isn't being executed alert("resizing window"); }
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.
I have some javascript that I have written into the <body> section and it works great. But I would like to make it into a javascript function and define the function in the <head> section. Then in the <body> section write a small bit of javascript that would call the function() object. Code:
i try to use ajax with jquery, but i have a problem to make a "while" function inside my jquery file, to replace the former content of a div with the new one :at the beginning i load all the content through php, with a "while" function and then i create the links :
I have previously developed two scripts, both of which work really well, however I want to amalgimate them together if possible? My first script loads the content specified into a single div, replacing the content depending on which function is called, it also displays a loading gif during a timeout of 2 seconds. Here is the page:
<script type="text/javascript"> var str="Welcome to Microsoft! Microsoft Microsoft"; var stringToBeFound = 'Microsoft' var ReplaceString = 'site' document.write(str.replace(stringToBeFound , ReplaceString )); </script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
i am trying to make an online graphing calculator with javascript. dont ask how because i dont know. but there is an annoying error in a do...while loop. although it should break out of the loop when the |'s (absolute value signs) are replaced with Math.abs( and ). here is the code.
