Question

I have a image under div id myimage. Now I want to resize it by using change. I want from select box if selected 700X7000 then image\'s size will be height 700px and width 7

Answer 1

Well, to change it, you can just set the image's width() and height():

$('#myimage').width(700); // Units are assumed to be pixels
$('#myimage').height(700);

So for you to do the drop down box, you can just set the values to be something like 100x100, 200x200, etc. and split the selected value to extract the dimensions:

var parts = '100x100'.split('x');
var width = parseInt(parts[0], 10); // 10 forces parseInt to use base 10
var height = parseInt(parts[1], 10);
