I have an image map, and want the user to be able to click on the map to select or deselect that area. ie assume the map is divided into 50 areas numbered 1 -50, I want a text input box on a form when someone clicks area 5 say, that choice will appear in the textbox, now they click 20,25 and 30 and the text box displays 5,20,25,30. Now if they click 25 again I need that choice to be removed thus the textbox becomes 5,20,30. I'm sure you get the picture.
Utimately I would like the areas to appear in a text area on different lines with a description beside, ie
<textarea>
5 - Red Area
20 - Blue Area
25 - Pink Area
30 - Orange Area
</textarea>
I am designing a website with an imagemap as a navigation pane and I want an effect to happen when certain parts of the image are rolled over by the mouse. I want to switch the imagemap image to a different one (one which highlights the rolled-over bit) depending on which bit gets rolled over. (Sorry if this is confusing) This is my code:
This doesn't work, the image stays the same no matter which bit the mouse rolls over. Can you please tell me where I am going wrong? I don't know javascript and am following instruction from this website.
I have an imagemap, where I want a menu to popup on 'onMouseOver'. The menu is inside a <div>. Basically I want the menu to popup, and then hide it when the mousepointer leaves the menu 'onMouseOut'.
I've been searching after this for hours with no luck. I'm nearly there, atleast in IE, but it's flickering. I want to get rid of the flickering, and also make it work in Opera and Firefox.
We have the function detailed below which controls some image in our website. However, one of the images we would like to place an imagemap in the top corner but after all of our attempts the javascript below seem to stop the imagemaps from working.
I am trying to get a pop up window to open when clicking an image map link. The pop up works but needs to be the size of the image (no white space) Image size is actually 365 x 500. I can not post the url because I am new. It pops up but is a small (not image size) pop up and has white space.
Some history: Although I know that it is considered 'old' technology, I have built hundreds of imagemaps over 10 years for a local photographer who uses a panoramic camera (now a spectacular digital one) to photograph weddings, schools etc. I then pop an imagemap area over each face and add a title (and alt text for IE viewers) that shows up on mouseover to identify the person.
I've been using the jQuery tools library recently and tried changing this tooltip demo which turns an image's title into a tooltip from:
Thus grabbing the title associated with an area rather than an image.
I just built a quick proof of concept using the image map of a family meeting on one of my sites, and viewed it in Firefox. As expected, on hovering over an area the tooltip popped up at top center of the image, with the title text in it. Wow! GREAT! I thought. ;-)
BUT...
In IE: Tooltip pops up, containing the matching title text, but far away from the clicked area and NOT at top center.
In Opera: No tooltip, browser's title box opens by mouse position, but with out title text, instead it contains the a href link that clicking in the area would go to.
In Chrome: No tooltip, no title.
In Safari: No tooltip, no title.
(BTW All tests were done in current browser versions under Win XP)
I just tried Tero's demo at [URL] in all browsers and it worked fine, in every case the tooltip appeared top center of the image, with the title text in it! So it would seem at first thought to be involved with the way browser manufacturers have built their DOM... But further reading indicates that all post v5 browsers use the same DOM model, so I'm stumped. I've Googled quite a few threads where folk have had js/DOM/imagemaps conflicts, but have found no post resolving the issue.
Since libraries such as jQuery claim to isolate us from browser variances, is it just that imagemaps are considered so 'out of date' that browser manufacturers haven't bothered to update their code to integrate them into the standard DOM? (Bravo FF, 'does it right' again!)
this page (http://users.rcn.com/**************/test72.html) will display new images when you mouseover the red and orange arrows on the menu on the right side in chrome, but not ff, ie, opera, and safari. Any ideas as to why these other browsers aren't running the code like chrome? guessing this is javascript related
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.
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:
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'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:
1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks". 2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"
Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?
and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?
This is a question about defensive web browsing. Ocassionally I run into a page whose JavaScript does something that I find obnoxious. I would like to turn off JavaScript only for that page (instead of disabling it globally). It would be cool if there were some way to do this through a "bookmarkable" JavaScript snippet using the javascript: pseudoprotocol. Does anyone know any trick to do any of this?
I am looking for a method to extract the links embedded within the Javascript in a web page: an ActiveX component, or example code in C++/Pascal/etc. I am looking for a general solution, not one tailored to a particular page/script.
Hopefully, the problem can be solved without recreating a complete Javascript interpreter. Any ideas?
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 would like to know how to write javascript such that, a part of it isnt considered as script, & rather as HTML. Code:
Ok, the layer div can be written using document.write. But, Google ad itself is a javascript isnt it. How can it be written into this? How does this work?
Ok so, this is my purpose: - to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML
Why? -Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering
My problem: Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')" if I use xxx.innerHTML=text, nothing happens
My 1st solution: Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt): if I eval the code, it deletes my current page and renders a new one for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text
What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML
Is this even possible? How would you go about it? I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...
Just a quickie: is it possible to place javascript within javascript? The following is the code I am using to create a pop-up for a picture gallery. I would like to place a banner from a banner exchange in bold under each photo. When I use the code below I get an error message:
Basically, on one of my sites I'm running adsense and today I added Chitika. The problem is, I can't run those type of ads through my banner advertising program.
The banner advertising program calls the banners/HTML from code like this:
And using that program I'm able to either choose a banner or HTML I want to display when that code above is used. It displays HTML ok... but when I try to run an ad of either adsense or chitika nothing displays on the page. The code that would be called is:
So... it looks like I can't have javascript call another javascript to display on a page. My question is then... how can I edit the above to make it work or how can I work around this problem? I'd really want this to work with Chitika and not so much with adsense... but it appears both Chitika and Adsense use similar javascript code.
How can I use NSS (Network Security Services) from Mozilla/Firefox Javascript?
I'm trying to sign some data using a private key in Javascript. I know the crypto module should allow that with the signText method, but some of the crypto methods seem to be broken, raising Not Implemented exceptions.
