Using margin on the body element in IE can cause unexpected values when using Jquery offset

Question

Using margin on the body element in IE can cause unexpected values when using Jquery offset

I am currently working on positioning a contextMenu using jQuery's jquery.ui.position. The library I am utilizing for the ContextMenu is available at this link:

https://swisnl.github.io/jQuery-contextMenu/demo

My approach to positioning the ContextMenu is as follows:

$(document).ready(function() {

    $.contextMenu({
        selector: 'td[id="tdMenu"]',
        trigger: 'left',
        position: function (opt, x, y) {

            try {

                opt.$menu.position({
                    my: 'right top',
                    at: 'right bottom',
                    of: $("#tdDiv")
                });

            } catch (e) {

            }

        },
        items: {

            "0": { name: "Hi" },
        }
    });
});

The corresponding HTML structure is as follows:

<table border="0" cellpadding="0" cellspacing="0" width="100%">
        <tr>
            <td id="tdDiv" style="background-color: yellow;">
                Menu Div
            </td>
        </tr>
         <tr>
            <td id="tdMenu">
                Click Here
            </td>
        </tr>
    </table>

In Internet Explorer 11 (IE 11), there is an issue where upon initial page load, the offset calculation by jquery.ui.position is incorrect when clicking on the td with the id tdMenu. It only calculates correctly on the second click.

Upon investigation, it was discovered that within jquery.ui.position, the offset calculation is done like this:

function getDimensions( elem ) {
    var raw = elem[0];
    return {
        width: elem.outerWidth(),
        height: elem.outerHeight(),
        offset: elem.offset() // Wrong value on first click, correct on second.
    };
}

An attempt to adjust by giving margin to the body as shown below:

<body style="margin: 0px;">

Removing the body margin resolves the issue and enables correct calculation even on the first click. However, removing the body margin is not an option. Can you suggest a workaround for this?

Based on the information provided, it appears that the issue stems from calculating an offset value before the webpage has fully loaded all styles and content. This results in an incorrect offset value when initializing your contextMenu.

To address this problem, consider replacing

$(document).ready(function() {
  // executes when DOM parser reaches </html> tag

  $.contextMenu({/* your stuff here */})
});

with

$(window).on('load', function() {
  // executes when all external resources/references (images, scripts,
  // stylesheets, iframes, etc...) have finished loading

  $.contextMenu({/* your stuff here */ })
});

This change is likely to resolve the issue. However, without a Minimal, Complete, and Verifiable example, thorough testing is required to ensure its effectiveness.

Note: The suggested solution delays the initialization of $.contextMenu() until the page has fully loaded. If you prefer to initialize $.contextMenu earlier, despite potential delays due to resource loading, one workaround involves initializing it on $(document).ready and updating it on $(window).load:

function cMenu() {
    $.contextMenu({
      /* your stuff here */ 
    });
}
$(document).ready(cMenu);
$(window).on('load', cMenu);

In practice, there may be a key element on the page affecting the offset (e.g., a stylesheet). By identifying this element through trial and error or elimination, you can bind the re-execution of your function to that element's onload event, allowing for more targeted optimization.

Modify the body style by removing it before the contextMenu event is triggered with show, and then reset the body style after the activated event occurs.

Here is an example:

$(document).ready(function() {
    var bodystyle = '';
    $.contextMenu({
        selector: 'td[id="tdMenu"]',
        trigger: 'left',
        events: {
               show : function(options){
                    bodystyle = $('body').attr('style');   
                    $('body').attr('style','');            
               },

               activated : function(options){
                    $('body').attr('style', bodystyle ) ;            
               }
        },
        position: function (opt, x, y) {

            try {
                opt.$menu.position({
                    my: 'right top',
                    at: 'right bottom',
                    of: $("#tdDiv")
                });

            } catch (e) {

            }

        },
        items: {

            "0": { name: "Hi" },
        }
    });
});
