Are there pointers in Javascript available, like for example in Turbo Pascal 7? :)
So i could use
function TestFunc(PointerToFunctionA, FunctionAItself) {
FunctionAItself('Hallo'));
//And how to use the Pointer then?
PointerToFunction('Hallo')...???
}
function PassedFunction(TextToShow) { alert(TextToShow); }
TestFunc(^PassedFunction,PassedFunction);
Using a combination of the Javascript Anthology (except I'm still near the beginning) and stuff I find online I'm attempting some Javascript on a form page. What I'm trying to do is let those without JS have a text input with a maxlength of 100 (yes there's a filter in the back end too), while those with scripts-on get a textarea and a character counter underneath (last.fm does this with its shoutboxes). Maxlength does not work in textareas, at least not cross-browser. We figure the visual (and audial) feedback of maxlength is necessary for those without scripts, so they get the text input. So, my script needs to to do a few things:
-remove the text input and place in a textarea and a span.
-have a (onkeyup?) counter that shows how many characters the user has typed in
-? maybe something to stop the textarea over 100 characters, like maxlength does, as a visual/audial cue.
I've written something that does step 1, however
-it's still in the HTML (I wanted to make sure where errors were before putting it in an eventloadlistener, which is what I ulitmately plan to do)
-I think it's messy. Certainly I'd like this section to be lean and simple before getting to the counter code.

I've made a code that finds the factors of an inputted number. Here's the script code...
However, when I factor it, It will go to a blank unformatted page to list the factors. How can I list the factors on the webpage itself like a div? I tried using a <div> and innerHTML but it only lists one factor.
i have a problem with fading things in and out using jquery. Please check it out.THe problem is that sometimes the fading in happens before the fading out. What can be done to fix it?

i have a box:
<img id="imgSearch" src="" alt="Websites" />
<input type="button" value="Toggle Search" id="btnSearch" />
^being the button to toggle between websites.
basically i'd like this button to toggle between different websites when clicked.
secondly:changing span tag colors
html code:
Traffic Light: <span id="trafficLight"></span>
<input type="button" value="Prevent Accident" id="btnTraffic" />
i'd like to change the color of this span id by pressing the button. so in this case it would change red, yellow green and last:
changing the font in a bold tag bold by pressing a button
html code: (note, the font weight in normal in css for bold)
<b>i want this bold when you hit the button!</b>
<input type="button" value="Set Bold" id="btnBold" />
Can a checkbox do 2 different things after it is clicked? Right now I am using this...
<input type="checkbox" onclick="processCheckbox(this);">
<input type="checkbox" onclick="activLink(this.checked)">
I don't want to have 2 checkboxes on my page, just 1 and get the same result.
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]...

I'm developing a website utilizing Jquery Drop Shadow and thickbox and other things. I just implemented the thickbox and thought that maybe the slow response was my system (I've had photoshop, 12+ browser windows up, etc). I realize that may not be the case and I suspect jquery's drop shadow is a hog. I don't want to go through the entire code and implement a different shadow method at this point. Instead I'm wondering if anyone can verify this issue
[URL]... Click on the "Film Reel" and it may be especially slow to load. If you suspect it is my use of the Jquery Drop Shadow, can you recommend ways I could optimize it? One idea I have is to toggle it off and on when thickbox is opened and closed. However I don't know how to do that yet.

I found some javascript methods but I already have an "onclick" event on my submit button (to make sure people agree to the cancellation policy)....
Is there a way to multitask and do all those things with one script?
How can I make something in jQuery slideDown without pushing things under it down? To take it out of the flow so it just overlays a slidedown like a typical dropdown menu? Can slideDown be used for that?

View 1 Replies View RelatedI 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 have one site that has a bunch of cool easy javascript tricks that allow the user to change the page designs and other things. I had put a lot of time, effort, and $$$ into this site, and it was where I make partial income to provide for my family. Lately, I have noticed that some browsers (Chrome) will not allow the user to paste my javascript codes into their address bar.
Example: if user pastes "javascript: alert(2+2);" into their address bar in Chrome (and some IE I have heard from visitors) it will do a google search on alert(2+2) and will completely strip the "javascript" part out.

Also, the caption text transitions in with bolded elements properly appearing, and then they flip to regular text (the whole line of text transitions a bit strangely).
We run a click and sales tracking solution for our advertisers and as such we are having a few issues with browser compatability for certian sites that are ont eh Magento platform. Essentially we are just trying to create an image call in javascript that uses a few pre-populated variables from the checkout process.
So teh issue we are having doesn't seem to be broser specific. We are trying to simplify the javascript call to ensure we have the highest possible chance of compatiablity. Obviously now with so many differnt browsers and also mobile devide connectivity this is making things even harder. We know that our javascript calls are failing as we've been monitoring our IIS logs and can see the image calls are being made with blank variables. There are 3 different elements to our checkout calls that maybe you guys have experience of with possible issues or fixes:
1. unescape function
2. onload event function for images
3. creating images dynamically
these are very basic elements of the javascript core but aout 5-10% of our calls are failing with blank variables being passed into the image call. So the questions is what elements of our call will be the possibel sources of failure?

1)i need to create a form with few fields like phoneno,website,address etc and one text area.
2) i copy n paste the details in the textarea n when i click d button. it should automatically populate things into the respective fields.
here s my logic wt i taught of:
1)read the first line in the textbox and load it into contact person field.
2)find the @ symbol and put it into the respective field and if there are more than 1 mail id load it into the same feild using commas.
3)if the phone no is 10 digits then load it into the mobile field else load the rest it into phone field.
4)find for words like road,street,block,stage,floor etc,if present then load it into the address field till the last comma is encountered.
5)the last digits in the address should be loaded into the pincode field.
6)the last word present in the address after the last comma and before the hyphen should be loaded into the city field.
7)find for www or http and load it into the website field,if not found leave it blank.

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'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):

<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"

<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG

------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
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.
Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:
two possibilities or the attribute type of script:
text/javascript (the one i usually use) application/x-javascript
what are the differencies between both?
depends on the html content?
for example html 4.0.1 versus xhtml 1.1?
