JavaScript - Urgent Help

I am a beginner so please help ASAP.
When I validate my code in validate.w3.org:

document.write("<img src='" + myNum +".jpg'/>");

I got an error that said:

--- required attribute "alt" not specified

I have a page in html, containing some text like " ABCDEFGHIJKL" etc. This text has also a website link (hyperlink) with it. This website link changes on each refresh of page. Such link changes due to javascript runing behind on it. I just want this link each time stored in a PHP variable. Such text always appears on a certain position on the page (X,Y). Can you please help me on it.? I can provide additional details on request. Your early answer is required.

Hi, i am new to javascript and i am giving a task to create a javascript page, i need a javascript that will calculate and generate a simple Quotation with total price of item selected and its quantity in a new page and in tabular form, i need this for 2 check-boxs that has the value, 2 dropdownlist and the price.

I'm a newbie to php and javascript. I want some checkbox to hide some rows of my table so i did a search and i found a few javascript codes but yet I couldn't make it work the way I wanted it. When I uncheck a checkbox ONLY the first table rows get hidden, the other tables don't? can't I ID some rows? Please I need help :(

My javascript code is:

Quote:
<script type="text/javascript"><!--
function showHideTR(idx,vis) {
var tbl,row;
if(document.getElementById && document.getElementsByTagName) {
tbl = document.getElementById('tbl');
if(!tbl || (idx >= tbl.getElementsByTagName('tr').length)) return;
row = tbl.getElementsByTagName('tr')[idx];
} else if(document.all && document.all.tags) { // IE4 support
tbl = document.all.tbl;
if(!tbl || (idx >= tbl.all.tags('tr').length)) return;
row = tbl.all.tags('tr')[idx];
}
if(row) {
if(!vis) {
row.style.display = 'none';
} else {
// conditional compilation to hide the try-catch blocks from IE4
/*@cc_on @if(!@_jscript || (@_jscript_version >= 5)) @*/
try {
row.style.display = 'table-row';
} catch(e) {
row.style.display = 'block';
}
/*@elif(@_jscript_version < 5)
row.style.display = 'block'; // for IE4
@end @*/
}
}
}
function getStyle(el,styleProp)
{
var x = (typeof(el)=='string')?document.getElementById(el):el;
if (x.currentStyle)
var y = x.currentStyle[styleProp];
else if (window.getComputedStyle)
var y = document.defaultView.getComputedStyle(x,null).getPropertyValue(styleProp);
return y;
}
window.onload = function() {
if(!document.getElementsByTagName) return;
var tds = document.getElementsByTagName('td');
for(var i=0;i<tds.length;i++) {
tds[i].onclick = function() {
alert(this.parentNode.tagName+' = display : '+getStyle(this.parentNode,'display')+
'\n'+this.tagName+' = display : '+getStyle(this,'display'));
}
}
}
// -->
</script>

<!-- <script type="text/javascript">

A date field with calender in it so taht value can be selected from the calender and passed
on to the database.
A option on the GUI that would create a csv file on the server.

- It also needs to change back when clicked again.

I know there are alot of experienced coders out there and I'm eager to learn... help would be appreciated!

Hi I'm trying to download the security image from this site (at the bottom):

http://pacesalsa.promotionexpert.com...2/register.jsp

However, every time one refreshes the image, the image changes (obviously). So, I'm trying to figure out how to download the current image on the page to a jpg or png (or any image file type). Could someone please tell me how to do this? Thanks.

Currently if parts 1 or 2, or parts 3 or 4 don't match, the form works correctly. You receive the alert 'You must select the same number of seminars for the morning and afternoon on day X', and the form stops. However, if you select the same amount of numbers for this section of the form, but do not complete e.g. 'first name', you receive the alert 'Please fill in the first name then resubmit', but then when you 'OK' the alert the form submits anyway.

Any help? I need to get this sorted this morning.

Many thanks,
Sam
