Question

jquery has a strange behavior where the dialog window will cover up the scrollbar when the main

Currently, I am utilizing jQuery dialog to display a dialog window. I have managed to position it at the bottom left corner as desired. However, when the main window contains a scrollbar, the dialog ends up overlapping with the scrollbar instead of aligning with the bottom right corner. This unexpected behavior occurs because the dialog is positioned at the bottom left of the scrollbar.

I have attempted to use the position object option in jQuery dialog without success. I have experimented with all four values: fit, flip, flipfit, and none in the collision option of the position object, but none of them have resolved the issue.

Although I have implemented a workaround by calculating the width of the scrollbar and adjusting the dialog position accordingly in various places, I am seeking a more API-based solution.

Does anyone have any insights on how to achieve this?

Answer №1

I had success with the following example (code, fullscreen):

$("#dialog").dialog({
    position: {
        my: "right bottom",
        at: "right bottom",
        of: window
    }
});

It's worth noting that the code is enclosed within a $(function(){}) block, ensuring the dialog is created after the DOM has loaded and the browser has determined if a scrollbar is necessary. It's possible that you might be initializing the dialog too soon.

When it comes to displaying scrollbars on the left, all browsers seem to struggle. The common practice among famous news websites in Hebrew and Arabic is to use right scrollbars, making it a de facto standard regardless of language.

The issue with left scrollbars goes beyond just aesthetics.

Safari refuses to show a left scrollbar even when HTML is marked as RTL.
Firefox displays the left scrollbar but messes up absolute calculations for the left and top positions.
- For example, if you have an image marked as RTL in HTML and want to overlay a div on top of it, Firefox will mistakenly consider the origin point to be the right-top side of the left scrollbar instead of the correct location. This leads to misalignment issues due to the presence of the scrollbar on the left.
Chrome appears to handle this situation better than other browsers. However, compatibility issues with other browsers often require implementing browser-specific solutions anyway.
IE9 and IE8 exhibit similar behavior to Firefox.

In essence, this answer serves more as a rant to shed light on the challenges posed by left scrollbars across different browsers.

Are you using a Mac and dealing with those annoying auto-hiding scrollbars? One solution you can try is using CSS to ensure the scrollbar is always visible on the body:

body { overflow-y: scroll }

It's difficult to precisely determine the exact boundaries of the div excluding the scrollbar since the scrollbar is contained within the div itself. Unlike a separate container, the scrollbar is not an independent element that can be subtracted from the total area. This is particularly evident when using CSS and specifying overflow: scroll. However, there might be potential solutions available through various jQuery plugins designed for Scrollbars.

One workaround could involve adjusting the position by creating a consistent 20px margin. Below is an example utilizing this approach:

    $( "#dialog" ).dialog({
        position: { 
            my: 'right bottom',
            at: 'right-20px bottom',
            of: $("#some_div")
        }
    });

Here's a handy trick to determine the scrollbar width for any browser. You can implement it as a function:

How can I find out the browser's scrollbar sizes?

If you're concerned about potential whitespace when the scrollbar is not visible, you can force it using CSS:

body {
  overflow-y: scroll;
}
