I am trying to use the jQuery dialog UI library in order to position a dialog next to some text when it is hovered over. The jQuery dialog takes a position parameter which is measured from the top left corner of the current viewport (in other words, [0, 0] will always put it in the upper left hand corner of your browser window, regardless of where you are currently scrolled to). However, the only way I know to retrieve the location is of the element relative to the ENTIRE page.
The following is what I have currently. position.top is calculated to be something like 1200 or so, which puts the dialog well below the rest of the content on the page.
$(".mytext").mouseover(function() {
position = $(this).position();
$("#dialog").dialog('option', 'position', [position.top, position.left]);
}
How can I find the correct position?
Thanks!
Check your <!DOCTYPE html>
I've noticed that if you miss out the <!DOCTYPE html> from the top of your HTML file, the dialog is shown centred within the document content not within the window, even if you specify position: { my: 'center', at: 'center', of: window}
EG: http://jsfiddle.net/npbx4561/ - Copy the content from the run window and remove the DocType. Save as HTML and run to see the problem.
This page shows how to determine your scroll offset. jQuery may have similar functionality but I couldn't find it. Using the getScrollXY function shown on the page, you should be able to subtract the x and y coords from the .position() results.
Taking Jaymin's example a step further, I came up with this for positioning a jQuery ui-dialog element above the element you've just clicked (think "speech bubble"):
$('#myDialog').dialog( 'open' );
var myDialogX = $(this).position().left - $(this).outerWidth();
var myDialogY = $(this).position().top - ( $(document).scrollTop() + $('.ui-dialog').outerHeight() );
$('#myDialog').dialog( 'option', 'position', [myDialogX, myDialogY] );
Note that I "open" the ui-dialog element before calculating the relative width and height offsets. This is because jQuery can't evaluate outerWidth() or outerHeight() without the ui-dialog element physically appearing in the page.
Just be sure to set 'modal' to false in your dialog options and you should be a-OK.
above solutions are very true...but the UI dialog does not retain the position after window is resized. below code does this
$(document).ready(function(){
$(".test").click(function(){
var posX = $(".test").offset().left - $(document).scrollLeft() + $(".test").outerWidth();
var posY = $(".test").offset().top - $(document).scrollTop() + $(".test").outerHeight();
console.log("in click function");
$(".abc").dialog({
position:[posX,posY]
});
})
})
$(window).resize(function(){
var posX=$(".test").offset().left - $(document).scrollLeft() + $(".test").outerWidth();
var posY = $(".test").offset().top - $(document).scrollTop() + $(".test").outerHeight();
$(".abc").dialog({
position:[posX,posY]
});
})
As an alternative, you could use the jQuery UI Position utility e.g.
$(".mytext").mouseover(function() {
var target = $(this);
$("#dialog").dialog("widget").position({
my: 'left',
at: 'right',
of: target
});
}
Thanks to some answers above, I experimented and ultimately found that all you need to do is edit the "position" attribute in the Modal Dialog's definition:
position:['middle',20],
JQuery had no problems with the "middle" text for the horizontal "X" value and my dialog popped up in the middle, 20px down from the top.
I heart JQuery.
I've tried all the proposed solutions but they won't work because the dialog is not part of the main document and will has its own layer (but thats my educated guess).
$("#dialog").dialog("option", "position", 'top')$(dialog).dialog("open");Then get the x and y of the displayed dialog (not any other node of the document!)
var xcoord = $(dialog).position().left + ADD_MODIFIER_FOR_X_HERE;
var ycoord= $(dialog).position().top + ADD_MODIFIER_FOR_Y_HERE;
$(dialog).dialog('option', 'position', [xcoord , ycoord]);
This way the coordinates are from the dialog not from the document and the position is altered according to the layer of the dialog.
instead of doing pure jquery, i would do:
$(".mytext").mouseover(function() {
x= $(this).position().left - document.scrollLeft
y= $(this).position().top - document.scrollTop
$("#dialog").dialog('option', 'position', [y, x]);
}
if i am understanding your question correctly, the code you have is positioning the dialog as if the page had no scroll, but you want it to take the scroll into account. my code should do that.
I don't think the speech bubble is quite right. I tweaked it a bit so that it would work and the item opens right under the link.
function PositionDialog(link) {
$('#myDialog').dialog('open');
var myDialogX = $(link).position().left;
var myDialogY = $(link).position().top + $(link).outerHeight();
$('#myDialog').dialog('option', 'position', [myDialogX, myDialogY]);
}
$(".mytext").mouseover(function() {
var width = 250;
var height = 270;
var posX = $(this).offset().left - $(document).scrollLeft() - width + $(this).outerWidth();
var posY = $(this).offset().top - $(document).scrollTop() + $(this).outerHeight();
$("#dialog").dialog({width:width, height:height ,position:[posX, posY]});
}
Positions a dialog just under an element. I used offset() function just because it calculates the position relative to upper left corner of the browser, but position() function calculates the position relative to parent div or iframe that parent of the element.
http://docs.jquery.com/UI/API/1.8/Dialog
Example for fixed dialog on the left top corner:
$("#dialogId").dialog({
autoOpen: false,
modal: false,
draggable: false,
height: "auto",
width: "auto",
resizable: false,
position: [0,28],
create: function (event) { $(event.target).parent().css('position', 'fixed');},
open: function() {
//$('#object').load...
}
});
$("#dialogOpener").click(function() {
$("#dialogId").dialog("open");
});
you can use $(this).offset(), position is related to the parent
a bit late but you can do this now by using $j(object).offset().left and .top accordingly.
$("#myid").dialog({height:"auto",
width:"auto",
show: {effect: 'fade', speed: 1000},
hide: {effect: 'fade', speed: 1000},
open: function( event, ui ) {
$("#myid").closest("div[role='dialog']").css({top:100,left:100});
}
});
After reading all replies, this finally worked for me:
$(".mytext").mouseover(function() {
var x = jQuery(this).position().left + jQuery(this).outerWidth();
var y = jQuery(this).position().top - jQuery(document).scrollTop();
jQuery("#dialog").dialog('option', 'position', [x,y]);
});
To put it right on top of control, you can use this code:
$("#dialog-edit").dialog({
...
position: {
my: 'top',
at: 'top',
of: $('#myControl')
},
...
});
Here is the code..,how to position the jQuery UI dialog to center......
var $about = $("#about");
$("#about_button").click(function() {
$about.dialog({
modal: true,
title: "About the calendar",
width: 600,
close: function() {
$about.dialog("destroy");
$about.hide();
},
buttons: {
close : function() {
$about.dialog("close");
}
}
}).show();
$about.dialog("option", "position", 'center');
});
To fix center position, I use:
open : function() {
var t = $(this).parent(), w = window;
t.offset({
top: (w.height() / 2) - (t.height() / 2),
left: (w.width() / 2) - (t.width() / 2)
});
}
I tried for many ways to get my dialog be centered on the page and saw that the code:
$("#dialog").dialog("option", "position", 'top')
never change the dialog position when this was created.
Instead of, I change the selector level to get the entire dialog.
$("#dialog").parent() <-- This is the parent object that the dialog() function create on the DOM, this is because the selector $("#dialog") does not apply the attributes, top, left.
To center my dialog, I use the jQuery-Client-Centering-Plugin
$("#dialog").parent().centerInClient();
You ca set top position in style for display on center, saw that the code:
.ui-dialog{top: 100px !important;}
This style should show dialog box 100px bellow from top.
