I 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?
I currently have an image and underneath it there are 6 thumbnails. When I run the cursor over them the big image changes. This works fine. However, I would like to have text beside the big picture that also changes depending on the thumbnail over which I am hovering.
I have tried to work it out myself but failed miserably. I have tried forums, but can't find what I need. My code as it stands at the moment is:
<script type="text/javascript"> if (document.images) {image0 = new Image; image0.src = "i/p0.png"; image1 = new Image;
I'm only new to Jquery and Ajax for that matter, understand JavaScript but don't work with it everyday. I have a function from Jcarousel that is populating a div with images (talking to a .txt file which contains the url), JavaScript then writes out the image. function getItemHTML(data){ var split = data.split(";"); var url = jQuery.trim(split[0]); var title = jQuery.trim(split[1]); var url_m = url.replace(/_s.jpg/g, '_m.jpg'); return '<a href="' + url_m + '" title="' + title + '" class="thickbox"><img src="' + url + '" width="' + 75 + ' " height="' + 75 + '" alt="' + title + '" /></a>'; };
And this is the function talking to the datasource function loadItemHandler(carousel, start, last, available){ if (available) { // Trigger loaded carousel.loaded(); return; }var cr = carousel; jQuery.get("example_dynamic_ajax.txt", function(data) { appendItemCallback(cr, start, last, data); });}; Now what I would like to do is instead of populating with images from .txt file I would like to populate with code from another .html page (a html page containing a table code). I'm just not entirely sure what object I need to use and how to go about that. Full code that I am working with is here: [URL].
I 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?
Problem is it doesn't do anything. When I only have one image set to change on mouseover it works fine.. I put two or more in there it doesn't work on any of the images.
I've got a Javascript which changes the background image of the body by rotating other images. What I want is the script to change the background to a specific div and not of the whole body section. Since I'm not an expert in Javascript I have Googled a lot but couldn't work it out till now. In other words that I want is to alter/change in the script the line "...document.body.background=processed [abc].src.." in a way and add ... so that this script works for a specific div and not only for the whole webpage...
<script language="Javascript"> var bgimage=new Array() bgimage[0]="image1.png"[code]....
I have a frame based wizard. I need to change the image of selected step dynamically. There is a normal and selected image for each step. Here is a javascript function to change image when user selects perticular step. Code:
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.
I want to swap the source of two images when you click on one image. Basically, I am switching on/off states. But I can't even get the first part to work. Here is a function that I would think replace the word "off" in the image file name with "on" when you click on an image with the class .img-swap. After that I would imagine I would toggle the class of each somehow.
i have a document that places, reads cookies, and counts visits. it's design is to display text reading: "you have visited this site "x" times. this works fine - last week's assign. My assignment this week is to modify this document to display 4 images in succession. first, using a series of "if" statements within the body. next, is to replace if statements with switch statement. finally, to use an array to display images. i've been working on this for a week, and have made seemingly no progress. this is my starting point:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <HTML lang="en"> <HEAD> <TITLE>Track User Visits</TITLE>
I'm having 3 images work as 3 buttons. I want to make them when the user clicks on one of them it changes it's image and the image of the other 2 div tags.
Here's my html code <!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 TransitionalEN" "[URL]"> <html xmlns="[URL]"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" type="text/css" href="css/style.css" /> <link rel="stylesheet" type="text/javascript" href="js/Javascript.js" /> <script language="javascript" type="text/javascript"> function changeDiv_ToEnglish() .....
And here's my css code for only the 3 divs @charset "utf-8"; /* CSS Document */ #empty { width:69px; height:40px; float:left; } ..... The problem is : nothing occurs when I click on the arabic , english , japanese divs.
Do you see how the numbers 1, 2, 3, 4 are being displayed on the page? How can you make the images change everytime the user clicks a different number to display different images?
I have a nice little script that changes a company's logo (displayed in a side bar) when the user mouses over a part of an image map.
Here is the basic code:
My question is, how can I get three different images (company logo, weekly price chart and monthly price chart - all of which are in an image folder on my server) to change on this one mouseover event. I tried replicating the function three times and altering each function's name but that ended up screwing the whole thing up.
I have a problem when changing images and image maps with mouseover and click events in IE. Firefox, Chrome and Safari all work well but IE does not. It's hard to describe but when I mouse over a hot spot the image changes and then right away changes back. you can see it here (http:url....): here is the Javascript code:
var current_overID = ""; var last_overID = ""; function item (img_name,width,height)[code]....
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 ?
<script language="JavaScript"> <!-- Activate cloaking device var randnum = Math.random();[code]....
Now, this works fine with every manual refresh of the page and I can obviously get it to work with a <META> refresh, but I would like to do achieve this without resorting to this crude method.Note that I have additional code to stretch the image to the client browser resolution.I found this topic which look svery similar to what I want but doesn't have any code for the background image scaling ... http:[url]....
I have a button class within the html called mygallery_pause_resume and i need to split it into two classes using Javascript (_mypause, _myresume) where I can assign different backgrounds to the buttons.I have an array that activates in an onclick event so that the buttons labels change to play/pause. I have included the code from the template below,
Whats the best way to change text using the DOM? innerHTML makes it easy - for example, I can change the text of a div by indexing the div by its id and then setting its innerHTML.
With the DOM, its easy to get to an element becuase you can use its id. But to get to the insides of an element, you have to delve into the children.
Can I be garaunteed that the first child of a div will be the textnode I want?
I feel as if I'm groping blindly in the dark after I get my div and start changing the children. I can get things to work that way, but I don't feel comfortable about it.
Is there a way to change the displayed text on a web page using some combination of Javascript and DHTML? NOT in a text box. As far as I know (with my limited knowledge) the only way you can do this is with a textbox or images, which is not what I'd like to do. There's gotta be a way to do this, right?
So I'm trying to change the background color of a textbox depending on how many characters are enter (putting it green/red depending on count), and I'm having a hell of a time. There are 50 different textbox IDs on the page (give or take, dynamically generated), each unique/sequentially numbered (id1, id2 ... id50).Now I'm not that good with Javascript, but this is what I can up with so far.I was trying to use 'this.id' so I wouldn't have to name each of the IDs.
I'm building a template editor and changing some of the variables.
Part 1.
Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s
I need to be able to fill out two fields to change DEALERNAME and 00/00/00. I found a way to do this but it required the output to be in a field. I need it the output to look no different than before.
Part 2.
I'm using this to change some text via radio button but I would like an option to select how many details are there is the first place. Say they only want 1 or 2 details and not 3.
Head <script language="javascript" type="text/javascript"> function detail1a(){ document.getElementById("detail1").innerHTML = "Up to 5 Quarts"; }
I want to change the color of a each word in a block of text. For example I want each word in a sentence to change to a different color automatically.
I was thinking that is if it was possible to move the color tags around each word and put a time delay between each time it moves but how I will accomplish these two actions.
I was wondering how you allow the user to highlight text they've typed (in a form) and click a button to edit its style (placing tags around the highlighted text).
Could someone explain this a little further and perhaps provide an example.
