I'm trying to load an image and retrieve its width/height. The image appears to be okay, but width/height are zero. The image isn't part of the page (yet), I'm simply creating it for later. Anyone got any help for me?
var id = this.FileName.replace(".png", "").replace(".jpg", "") + "_" + index;
var src = this.Path + this.Filename + "?" + new Date().getTime();
this.ItemImage = new Image();
$(this.ItemImage).attr(
{
'src': src
,'id' : id
});
this.Width = $(this.ItemImage).width();
this.Height = $(this.ItemImage).height();

That is the answer to your problem.
since the image isn't loaded yet the browser won't set the width and height properties. will the image ever be loaded by the browser??
maybe try something like...
$('<img />').attr('src', 'http://urdomain.com/name.jpg').load(function(){
if(true === this.complete) {
var width = this.width;
var height = this.height;
} else {
}
});

Your suggestion didn't work. I'm going to try adding a hidden div to the document, and then add images to that div. Maybe that will do what I need...

I want to Add Number of Days with the Date object and get the New Date. i used this method to add Days
FromDate.setDate(FromDate.getDate() +12)
But this method is not working, if the month is February
EG: if the From Date is 20-02-2013, if i add 12 Days with this date, will get result as 01-03-2013.
Is there any other method to add days and check its leap year or not

Are you sure you're looking at the correct month? In JavaScript, the Date object uses a zero-based month, so if getMonth returns 2, the date is in March.
var date = new Date(2012, 01, 20);
date.setDate(date.getDate() + 12);
alert(date);

Can you give an example of your code that isn't working?? I tried the following and it all appears to be working just fine.

Hi Robymon,
The example you have given is incorrect.
Adding 12 days to 20-02-2013 will not give result as 01-03-2013, but will give 04-03-2013
The solutions given by "Richard Deeming" and "Dennis E White" are correct.
Thanks & Regards,

There is usually many ways to do string manipulation but one way would be to split on the = and then you'll have the rightmost character to be the starting of your next string. You'll have to put in a case for the first one.
Or, just loop through each character and process.
There are only 10 types of people in the world, those who understand binary and those who don't.
