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:
View 2 RepliesI am in the process of writing a script that will dynamically generate a table using javascript and XML. I can get all of my data to feed in with no problem but am getting hung up on a few small syntax issues. Basically I need to assign a unique id equal to [i] (instead of id="answerDiv", in bold below) so that when calling showHide() it will show/hide one specific div.
Current Table Script
Code:
//table 2
document.write("<table id='tbl2' cellpadding='0' cellspacing='0' border='0' style='display: none; width:236px;'>");
var x=xmlDoc.getElementsByTagName("feature");
for (i=0;i<x.length;i++) {
document.write("<tr><td class='eventDate'>");document.write(x[i].getElementsByTagName("question")[0].childNodes[0].nodeValue);
document.write("</td><td class='eventText'>");
document.write(x[i].getElementsByTagName("content")[0].childNodes[0].nodeValue);
document.write('<a href="#" class="redLink triviaAnswer" onclick="showHide();">click for answer</a><br><br>
<div id="answerDiv" style="display:none">');
document.write(x[i].getElementsByTagName("answer")[0].childNodes[0].nodeValue);
document.write('</div></td></tr><tr><td colspan="3"><div class="tabs_hr"></div></td></tr>');
} document.write("</table>");
Show/Hide Function
Code:
function showHide(){
var answer = document.getElementById('answerDiv');
if(document.getElementById('answerDiv').style.display == 'none') {
answer.style.display = "block";
} else {
answer.style.display = "none";
} }
I am doing a project where I would like to be able to generate a series of variable names dynamically in the following example
var paper1 = new Raphael('img1', 500, 500);
c1 = paper1.rect(0, 0, 50, 20, 5);
var paper2 = new Raphael('img2', 500, 500);
c2 = paper2.rect(0, 0, 50, 20, 5);
would like to use a loop to increment names
for (i=0;i<=5;i++)

I found this code in another thread... basically, I need to be able to display a certain image based on the page's title... for instance if the title is: Lotus 7, I need image lotus.jpg to display in an element on the page, however, if the title is Bodhi 9, I need image bodhi.jpg to display in the same element
var imgs = new Array();
imgs[0] = new Array();
imgs[0][0] = "Research";

For a computer science class homework assignment I need to create a page where an image changes randomly when a button is clicked. This is what I have so far, nothing happens when button is clicked. I need the button to randomly return one of the five images described in the emotions function. Please help, I sorely need it.

I have a div set up like this
<div id='y' style='background-image: url(./randomcolor.php?ibase=

php echo $entity

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?!
View 1 Replies View RelatedLet's suppose a user enters his message " My name is John" in a textarea. and he likes to modify by adding <b> tag before the word "John" after he enters "My name is John".
In order to add <b> tag in front of the word "John", he should put his mouse before "John" and enter <b>.
but instead of entering <b>, I like to make the user to click the button "<b>", then <b> is automatically created just before the word "John" in the textarea.
Of course </b> will be needed later, but forget about </b> for simplification.
In short, I like to make the button "<b>" , in order to add <b> tag in front of "John" after entering "My name is John."
I am trying to dynamically resize an image. Here is my code:
<img border="0" src="images/right.gif" width="16" height="100" name="right">
<SCRIPT Language=Javascript>
<!--
function ChangeImgSize(){
[Code]....
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 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.
Is there anyway to rescale a whole page homogeneously, so that

I'll get to the point, I'm a noob I'm using greasemonkey for a certain website. Basically, I'm using gm to refresh the page after a certain time, I was however wondering, If I can set it to a random number between 2 specific times?
The code I'm using atm is setTimeout(function() { document.location.reload(); } , 10000); I know I have to use math.random, well, I think I do. But I'm not sure how to do it between 2 certain times? So to summarise, I'm trying to refresh a page at any given random time between say 5-10 minutes.
In the forum, it usually talked about generating a number between 1 or 0 to that certain value using something like Math.round(Math.random() * 200); or Math.floor(Math.random() * 200);
But what do you do if you want to generate a number between 201 and 400.
I run a random number generating service for a RPG message board I go to, and my website generates only numbers from 1-100. How could I script this so that the user can get random numbers between 1-X?
View 4 Replies View RelatedI need a script that will generate a unique ID consecutive to the previous one when a user submits a form. For example, I submit the form and the confirmation page shows:
JGH100354101
I will need the next user that submits the form to have the confirmation page show:
JGH100354102
and so on and so on...
Is anyone aware of a simple form script that would accomplish this?
I am using following code to generate menus:
<?php
$menu = array();
$menu['home'] = 'Home';
$menu['mypage'] = 'My Page';
//Add in the format of: $menu['page name'] = 'Page Title';
$title='Home'; //Default title
function generateMenu() {
global $menu,$default,$title;
echo ' <ul>'; .....
But I have 6 menus and first three menu have sub menus. Above code generates only menus. I want to add sub menu also.
This is the code I have. i want unique Id for each text box(id="messageText"). PLEASE GIVE IDEA. As due to same ID of the text box the JS function is not showing the proper result and the characterleft count is not decreasing automatically.

Im working on my own little javascript engine at the moment.
One of the functions i would like to add to it is a fadeToBackground function. In essence, it would detect the element that is calling it and find out the background colour for that element. From there it would take a hex colour that it is given and then fade to the background colour.
To do this i need to generate an array of inbetween colours. Ie, i need something like #000000, #0000EE, #0000FF etc etc.
Does anyone know of an algorithm to calculate the colours in between two given hex values?
I want to be able to dynamically generate the colours so it is a drop in function for down teh track where you just give it a colour to fade from and it does the rest.
There is a form that I have been working on. The form needs to display information on it that, ideally, would be automatically generated.
So, for example, I open this form today 9/6/2007 and I sent it out. The form result would show the current date with a time of 6:00am and then the previous day's date with a time of 6:00am.
----Form Data----------------------------------
Data for: 9/5/2007 6:00am thru 9/6/2007 6:00am
Name: Yourname
Number: 123abc
-----------------------------------------------
So, again, I'm trying to write a script that will present current day and the previous day on the form and the results. I hope that I have been clear enough.
If anyone has any suggestions I am certainly open to look at them.

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:

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.
View 6 Replies View Related[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

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.
