How to Pseudo Clone Element Styles Using jQuery?

jQuery Plugin for Cloning Element Styles to a Pseudo Clone

Creating a pseudo clone of an element with different tags can be achieved using various approaches in jQuery. Here's a detailed explanation and solutions:

jQuery's getComputedStyle Plugin

For the specific requirement of returning an object of computed styles for an element, you can utilize the jQuery getStyleObject plugin, which retrieves all possible styles from any element, including IE browsers.

Usage:

var style = $("#original").getStyleObject();

Copy after login

Modifying jQuery's CSS Method

Another approach is to modify jQuery's css method as follows:

jQuery.fn.css2 = jQuery.fn.css;
jQuery.fn.css = function() {
    if (arguments.length) return jQuery.fn.css2.apply(this, arguments);
    var styleObj = {};
    // List of style properties to get
    var styleList = ['font-family','font-size','font-weight','font-style','color',
    'text-transform','text-decoration','letter-spacing','word-spacing',
    'line-height','text-align','vertical-align','direction','background-color',
    'background-image','background-repeat','background-position',
    'background-attachment','opacity','width','height','top','right','bottom',
    'left','margin-top','margin-right','margin-bottom','margin-left',
    'padding-top','padding-right','padding-bottom','padding-left',
    'border-top-width','border-right-width','border-bottom-width',
    'border-left-width','border-top-color','border-right-color',
    'border-bottom-color','border-left-color','border-top-style',
    'border-right-style','border-bottom-style','border-left-style','position',
    'display','visibility','z-index','overflow-x','overflow-y','white-space',
    'clip','float','clear','cursor','list-style-image','list-style-position',
    'list-style-type','marker-offset'];
    for (var i = 0; i < styleList.length; i++) {
        styleObj[styleList[i]] = jQuery.fn.css2.call(this, styleList[i]);
    }
    return styleObj;
};

Copy after login

With this modification, you can get the computed style object for the first matched element by calling:

var style = $('#original').css();

Copy after login

Other Editing Approaches

For the general problem of pseudo cloning an element for inline editing, consider these alternative approaches:

jQuery.clone() with .replaceWith(): Clone the original element, modify it to be an input field, and replace the original with the clone.
jQuery.replaceWith() with .data(): Replace the original element with an input field, storing the previous element's data in a data attribute. After editing, replace the input with the data.
ContentEditable attribute: Toggle the contentEditable attribute of the element to allow direct inline editing.
