How I could dynamically generate an image via Java/Javascript.
There will be a tiny sprite-like image in the middle. What I want is to have a partial circle around the sprite appear. It will have a drop-down with 3 options, each changing the diameter of the circle. Then I want the other input box to accept numbers and that number will decide how complete the circle is, out of 360 Degrees. For instance, if someone typed in 359, then their circle would be almost complete.
Using javascript, I want generate buttons and textboxes dynamically depending on selection from dropdown.Use asp.net with c# languasge.I will try using above code.But not solved the purpose
<head runat="server"> <title>Dynamically add Text Box and Button</title> <script language="javascript" type="text/javascript">
Whats wrong with this code? i decalre resultArray as a new Array(). Then in a for loop for each resultCount i declare resultArray[resultCount] = new Array(). Then i try putting in values for every resultArray[x][y], but when i go to output the array in another function, everything in resultArray is undefined.code...
I have a table with a couple random numbers, and i want to click a button that will dynamically regenerate the numbers each time the button is clicked without re-generating the entire table., im using DOM and innerhtml for these random numbers. heres the javascript and html code. so far, it just generates the random numbers when the page loads.[code]...

I've never worked with Ajax before but I've been reading up on it and done some basic tutorials and am comfortable with the concept of asynchronous communication and how everything works from a technical communication perspective. That being said I have no idea where to start on this project which seems like it should be fairly simple. 1. the browser will have a "working area" which is a rectangle of some decent size, there will be a toolbar of objects on the left hand side. This work area should be shown as a grid that the objects will be placed into.The size of this grid (basically the gridlines) will need to be generated automatically based on user input (also the size of the components/objects that will be dragged in and the size of the rectangle) if it is too large (say 500) i'd like a way to pan around and zoom in as well... 2. For simplicity say there are 2 components: Available, unavailable and an erase feature. 3. each object when dragged to the working area should create an object that has some properties (handled programatically from input elsewhere on a simple form) I will be placing these in a database server side. 4. I'd like to be able to drag across the grid to continuously add the selected object and I'd like to be able to click a button on the edge of the grid to fill in the entire row with the objects. From everything I've read on this it seems like this should be somewhat easy but again I don't know what framework to use to start. I'll be putting this in a drupal site and integrating it with a few modules if that makes a difference (i think that part of the programming will be separate from whatever specific implementation I use to get this Ajax part up though)
1. i want to get the current time, possibility no from client computer ( sometimes their time is wrong)? i dont know whether can achieve but if cannot, then never mind, just get from client computer.
2. for example now is 1:25 am, i want to generate dynamically every half an hour timing from 2 am(round up) till for example 11 am
I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).
So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)
i need to display an image randomly from an array that holds 4 addresses to 4 different images.i am having a hard time writing the img tag to the html page that will display the image.is it possible to use document.getElementById('id').innerHTML= "<img src="imgurl" />"?i have a span with an id of "theImage".i want to plop the img tag inside this span tag, but can't seem to get it to work.
I am having an issue with setting the background-image of a another div #x to the background image of #y.Correct me if I am wrong but I think you would do this in a simple case by saying
$ ( '#x' ).
[code]....
So when it does it, it is getting the URL of the generator (I logged it. what is actually being passed is [URL] This would require a server call to generate a new image, In this particular application, even if it wasn't exactly the image y had it would be acceptable. But it's not doing it. It is not getting any image at all. Am I doing something wrong, i.e. is it supposed to just work? I would think not, since the page has already been rendered. This is almost an ajax situation but I don't know how to do it for an image. I don't really want to generate a new image anyway, I'd be very happy to get the one that's already there. How would I access the actual image already attached to y and not do another server call?
I have a photo gallery... I was wondering if its possible using DOM scripting, to dynamically add a div around an existing image, making the new div the image's parent?!
The image does not get resized. I've been testing the page on current browsers (IE 8, Firefox, Chrome). I'm certain I'm doing something newbish, I don't really know Javascript all that well.
I have the following function to dynamically create an image (in this case a toolbox button):
Which works fine in IE8 and IE9, but in IE7 it refuses to pick up the style 'button'. I've even tried putting in btn.class='button' but JS throws up an error.
If I specify the style by btn.style.position='Absolute' it picks this up OK. However, it won't respond to the onclick event either.
I have heard that setAttribute is buggy with IE7, which is why I tried to specify each attribute directly.
The style sheet for class button is:
(BTW, no link to a website as this is local on my machine atm)
I want to display a 'preview' image for a file upload field. I assigned a function to the onChanged event for the file input that gets the value of the input text field, does some minor regex to fix the string, and then creates a new 'img' tag element and assigns the fixed string as the img's src: Code:
I have a div called large_pic. I have links beside it called pic1, pic2, pic3.
I would like to know how do I dynamically load images into the large_pic div whenever I click on a link. eg. clicking on pic1 link will load image1 into the large_pic div.
I would normally use iframes instead of the div, but that was when I was using tables. Now I am using divs, so I would like to use a div method if it's possible.
I have written some JAVA code that pulls and image from a DB and writes out the byte stream.When I call the URL directly I can see my image, however when I use something like:
function loadImage(filename) { $(document).ready(function() { alert('loadImage Called with ' + filename);
How do I dynamically display images in javascript without hardcoding it. I cannot use php or any other language. My teacher said it is doable in javascript. so right now I have it hardcoded in:
var bellTowerArray = new Array(); bellTowerArray[0] = "bellTower01.jpg"; bellTowerArray[1] = "bellTower02.jpg"; bellTowerArray[2] = "bellTower03.jpg";
[Code]....
I have multiple categories of images so not just these two. I don't want to have to type in fountain# etc and stuff like that.
I am creating a website and there is an option for the user (after he login to the website, he enters into his workspace page)to upload a background image of his choice to his workspace page.
Can the user dynamically upload a background image to his webpage?
Is it possible to dynamically add an image to a document using document.write? I've been playing around with it and I'm able to add the image tag, but the image is not being displayed. I'm only getting the place holder. The path to the image is correct and it does exist. Is there something special that must be done? I have tried doubling the slashes on the off chance that that was the problem.
[code]The image's height is 376px. So once the content goes after 376px, the blue bgcolor alternate takes over. But what i want is, once the content crosses the 376px height, the background image should dynamically stretch and not repeat.If this is not possible please do tell me how to increase the height of image in <img> using DOM methods.Again this should increase when the image's original height becomes greater than 376px
i have a function to dynamically create an image on the screen.the problem is i need it to slide down the screen, and i am using the function to have the picture up in more than one place at more then one one time.is their anything i can build into the div tag containing the image that would let it scroll down on its own (or some other method of accomplishing this i haven't thought of)i am putting my function below
function newtree(){ x_axis=Math.floor(Math.random()*height); newdiv=document.createElement('div');[code].....
the 'height' and 'width' variable are already set to the available room in pixels
I need a code to load imagexxx.png into a div every 5 seconds because the image changes dynamically and i need this using Ajax? the dynamic image generated by a php file > all what i need is run the ajax call every 5 minutes which run php script that return with an image ...
Having trouble specifically with onmouseout, onmouseover, and onclick used on areas in an image map. I'm trying to replicate the interactive hearing aid sound demonstration that can be seen on contactainc.com homepage but program it with javascript instead of flash. In the end of countless hours of research, frustration, and browser incompatibility (only chrome will actually change the image, ie nor firefox do anything except display one image).
Here's my guidelines...
The hearing aid has three switches. An image is created for each switch being selected. (3 images) The first switch is the off button or stops any sound playing when selected. The second switch upon selection plays a sound file of somebody talking. The third switch upon selection plays a sound file of the same person talking but also with background noise. A polygon area has been created for each switch as part of an image map. (3 areas)When a switch is selected (let's say switch 1), the other switch areas upon mouse rollover are highlighted in yellow (either switch area 2 or switch area 3) but the switch that was selected (switch 1) doesnt change upon mouse rollover. So this had me create 2 more images per switch displaying the switch selected and the two other areas highlighted. In total this is 9 images.(3 imaged per switch + (3switches * 2 switch areas highlighted) = 9).
The image names are as followed HearingAid(switch number)(nothing,a, or ) corresponding which switch is highlighted; a being bottom most switch area different than switch that's selected and b being top most switch area. So they are HearingAid1.png, HearingAid1a.png, HearingAid1b.png HearingAid2.png, HearingAid2a.png, HearingAid2b.png, HearingAid3.png, HearingAid3a.png, HearingAid3b.png.
The original image will change to the appropriate image out of the 9 images I created based upon left clicking an area to select the switch and mousing over other switches which are then highlighted.
My first problems from my first few attempts was that when I selected a different switch from the original off switch, my onmouseout for all switch areas was programmed to revert to the original off switch image and not the image I selected. So I thought I needed to dynamically change those attribute values to new ones every time I selected a new switch. I couldn't find anything in my research that would help me since I tried a lot of things and saw them all fail when testing them out.
My latest attempt I thought had the most potential but it seems like the onclick attribute is working at all. I can't figure out why either.
