jQuery looping through open dialogs to get/update position of each

I am trying to make the jQuery dialogs stay in their position relative to the window size, so for instance:

• If the original viewport width is 900px and there are 2 dialogs, one at 100,100 and another at 450,200
• When the window is resized to say 1200px, the first dialog would be 400,100 and the second at 750,200

I currently have this code handling the window resize, but it doesn't update the dialog positions:

jQuery(window).resize(function() {
    widthCompensation = getBrowserWidths();
    jQuery(".dialog-class").each(function() {
        var myPosition = jQuery(this).dialog("option", "position");
        var newLeft = parseInt(myPosition.context.offsetLeft+widthCompensation);
        var newTop = parseInt(myPosition.context.offsetTop);
        jQuery(this).dialog("option", "position", [newLeft,newTop]);
    });
});

Any help would be greatly appreciated!

Modified code:

function getBrowserWidths() {
    var standardWidth = 990;
    var actualWidth = parseInt(jQuery(window).width());
    var ret = (actualWidth-standardWidth)/ 2;
    return(ret);
}
var leftPositions = new Array();
var widthCompensation = getBrowserWidths();

jQuery(window).resize(function() {
    widthCompensation = getBrowserWidths();
    jQuery(".target-class").each(function(i) {
        var newLeft = leftPositions[i]+widthCompensation; 
        console.log(newLeft);
        jQuery(this).css({"left": newLeft+"px"});
    });
});

//loop through draggables to get their initial positions
jQuery(".target-class").each(function(i) {

    leftPositions[i] = myPosition.left;
});

Using this in the each, it quite worked for me (if the dialog doesn't reach the corner of the browser.

var myPosition = $(this).offset();
var newLeft = myPosition.left+widthCompensation; 
var newTop = myPosition.top;    
$(this).dialog("option", "position", [newLeft,newTop]);

Hope it helps ;)

For the each, you can use the Index (here i),

var newLeft = new Array();
var newTop = new Array();
$(".dialog-class").each(function(i) {
  var myPosition = $(this).offset();
  var newLeft[i] = myPosition.left+widthCompensation; 
  var newTop[i] = myPosition.top;   
  $(this).dialog("option", "position", [newLeft[i],newTop[i]]);
});

Didn't test it so not 100% sure, but here is the idea.
