View 3 Replies View RelatedI currently have a normal link like Code:<a href="http://sitepoint.com" class="link">sitepoint</a> and when a user clicks on it I want to be able to change the "link" class to a different class. However, I don't want to add anything to the actual link html. Is it possible to do this using javascript without modifying the original link code?
View 4 Replies View RelatedWorking on creating my own plugin and realized that I would very likely end up doing this again in the future. Unfortunately, I have an extremely short memory when writing code. I frequently have to re-read the code I've created the day prior so I can get back on track with what I was doing. As such, I'm a fervent commenter in my code.
So, I'm creating a jQuery plugin framework with comments for everything that's going on in the framework to prevent my brain from having to re-learn everything in a month or so when I do another one.
Plugin-savvy folks to take a look at this code and help me fill in the blanks and make corrections to those places where I'm way off base. As you'll likely notice rather quickly, this is taken from the jQuery plugin tooltip construct found here: [url]
In the below code i tried to write java scirpt in action attribute of form tag in html . Why i wrote that was i want to get the scirpt variable as a part of the url of the target page. I also tried using the location.href="targetpage?value="+value . But It is not redirecting to targetpage because of the action attribute in the form tag. And if we use location.href without action attribute only that script variable was posted and all other remaining textboxes and other form items are being not posted .. Thats why I wrote the scirpt in action attribute. I want the action attribute to work and also the java script variable to be posted .so i wrote the script tag in action attribute of form tag .

I'm using this code to force a PHP form to redirect. I already inserted a header for PHP and for whatever reason it's not working. This code works like a dream in Firefox, but it continuously loops in IE and makes it impossible to enter anything into the PHP form
<body onload="javascript: self.location.href = 'index.html';">
</body>
how to make this code not refresh IE literally every second?
The code below taken from net works as I need it. onLoad It execute another page from a different page, the only trouble is it keeps on refreshing constantly. How can I stop this??? I'm making it into a function and calling it onLoad.

I am making a mini wysiwyg editor for creating pdf letters which can be printed off.
In my editor is currently a html form which saves the textarea values each time the form is submitted. I want it to save to the database everytime its changed or maybe every few seconds.
This is some free code includeing with dreamweaver, What it does is check if flash player is installed. If it is installed then goto a url, if its not goto a differnt url. What I want to do, is change it from URL to variables so, instead of like test.asp?flash=true, I would like <%flash=true%>.
Heres the code, with an onload function.
function MM_checkPlugin(plgIn, theURL, altURL, autoGo) { //v4.0
var ok=false; document.MM_returnValue = false;
with (navigator) if (appName.indexOf('Microsoft')==-1 || (plugins && plugins.length)) {
ok=(plugins && plugins[plgIn]);
} else if (appVersion.indexOf(Ɖ.1')==-1) { //not Netscape or Win3.1
if (plgIn.indexOf("Flash")!=-1 && window.MM_flash!=null) ok=window.MM_flash;
else if (plgIn.indexOf("Director")!=-1 && window.MM_dir!=null) ok=window.MM_dir;
else ok=autoGo; }
if (!ok) theURL=altURL; if (theURL) window.location=theURL;
}
OnLoad event
Where it says Variable/URL is where I would normaly put the url, first one is if its found, second one is not found.
<body onLoad=";MM_checkPlugin('Shockwave Flash',Variable/URL,'Variable/URL,'true);return document.MM_returnValue">

View 4 Replies View Related[code]....We have a set list of shows that air each day, and on the site we have a marquee tag on the homepage that scrolls through showing each show and its broadcast time. Right now we're stuck changing this schedule each day by hand, but it's tough considering we're all college students ourselves and sometimes our own schedules simply don't allow the time.Is there a code that would allow this kind of a daily update to happen automatically?
The format for the schedule is such:

I'm just starting out in Javascript coding and my first assignment is to create a web page which the users are allowed to selecte dtheir favorite layout and formatting through the use of the className property. I wanted to use these four options the user can choose to change the display of the web page and text.
Gray background
White background
Sans-serif text
Serif text
If the user onclicks any of the options, the webpage will turn into that format. For example, if the user clicks "Gray backgound", the background color of the webpage will be Gray. If the user clicks Serif-text, the text in the web page will be in Serif text. The code I have right now doesn't let me click any of the links to change the display and text.

View 2 Replies View RelatedI have been trying to get better at my javascript as of late and there is this one particular color fading technique I have found that I am having trouble dissecting. The following code appears to be how they are making a rollover go from a dark gray to a subtle light gray with a nice fade but I can't exactly tell whats going on from the code. Is it just telling it to add a rgb point in so many seconds?
colorInit=

I am trying to dynamically clear the value of a form input field and then submit the form.When I used $('#my_field').val('') to clear the field, it was cleared on the screen but when the form was submitted the original value of the input field was posted.My browser is FireFox and I can see using FireBug that when the field is cleared, firebug is still showing the html code with the old value. E.G. <input type="text" value="old_value" />The same situation occurred if I used $('#my_field').attr('value', '') to clear the field.The same situation occurred if I actually changed the value of the field rather than just clearing it.To work around this problem I ended up using the $('#my_field').removeAttr('value') to clear the field before it was submitted.
View 1 Replies View RelatedI am a complete novice when it come to Javascript. I copied the script for displaying random images at a specific interval (from javascriptkit.com). I would appreciate knowing whether the following is possible:
The pages are based on tables, so the parts that change are all cells.
1. Can I define text instead of an image in the array? i.e. can I have the image change to say an apple in one cell and the next cell have text explaining what an apple is?
2. Would it be possible to put a countdown timer for when the image/text is going to change?
Ive got a small image of a power button and when pressed the inner section on the button changes to yellow, but when its pressed down Im also trying to get part of my H1 (main header logo title) to change to yellow.
Ive created a span with an id surrounding the letters of the H1 that I want to change, the id being : "power";
The javascript that I have come up with so far and works is as follows:
<img id="poweron" src="http://www.sitepoint.com/forums/images/power.png" alt="Power on button" onmousedown="this.src='images/poweron.png';" onmouseup="this.src='images/power.png';"/>
I understand Im not really supposed to be using inline JS, and I know Ive got to create a function for the onmousedown event to trigger changing the H1 text, so am I under the right impression that the JS so far written is redundant and will have to be re-written so thats contained within a script placed just before the closing </body> and an external script for invoking the main function ?
i've been reading up on access to the dom via js (i'm new to this dom
stuff)
i understand tutorials and info such as
http://developer.mozilla.org/en/doc...t.createElement
my problem: i'd like js to create the code for a stylesheet in the head
of the docuement!
i'm not sure how do do this (or if it can be done)
can i create the following...
<link rel="stylesheet" type="text/css"
href="mystyle.css" />
OR
<style type="text/css">
hr {color: sienna}
p {margin-left: 20px}
body {background-image: url("images/back40.gif")}
</style>
using the dom or anything else in js alone?...or am i fighting a losing
battle.
(what i really want at the end of the day is to detect the browser and
use a css file according to that file, either with js or php)...
I there any way for javascript to write/manipulate a file other than through a cookie?
View 1 Replies View RelatedI have an existing page that dynamically creates data in a popup
window. I am trying to change it to use an iFrame. Is the following
code valid:
The iFrame is as follows
<iframe src="theframe.html" name="theframe"></iframe>
"theframe.html" is an existing file initially with instructions.
In a script I do
thewindow=window.open("","theframe");
thewindow.document.open();
thewindow.document.write("Some Requested Data");
thewindow.document.close();
This is done multiple times depending on what the user requests each
time. Sometimes this works and sometimes it doesn't. I'm probably doing
someing very wrong but I don't know where to look for reference.
I'm not really opening a window so there must be another way to do it.
