Is There a jQuery Equivalent to `document.createElement()` for Efficient DOM Manipulation?

jQuery’s document.createElement equivalent method

When refactoring some legacy JavaScript code, you may encounter a lot of DOM manipulation. Here is an example of how to use pure JavaScript to perform DOM manipulation:

var d = document;
var odv = d.createElement("div");
odv.style.display = "none";
this.OuterDiv = odv;

var t = d.createElement("table");
t.cellSpacing = 0;
t.className = "text";
odv.appendChild(t);

To see if there is a better way to accomplish this task using jQuery, you can try:

var odv = $.create("div");
$.append(odv);
// 其他更多操作

But you may not be sure if this is a better approach.

One-stop solution

Here is an example of using jQuery to simplify the above operation into "one line" of code:

this.$OuterDiv = $('<div></div>')
    .hide()
    .append($('<table></table>')
        .attr({ cellSpacing : 0 })
        .addClass("text")
    )
;

In this In the example, we create the new element as an HTML string and pass it to the $() function. We then set the display style to "none" and append a table element with cellSpacing of 0 and class of "text".

This approach combines the power of jQuery with the simplicity of HTML strings, allowing you to perform complex DOM manipulations with a single line of code.

Performance considerations

Recent benchmarks on jQuery 1.4, 1.5, 1.6 and 1.7.2 show that creating elements using the document.createElement() method is faster than using the Jquery method Faster. However, this difference is very small and insignificant for most applications.

Therefore, code simplicity and potential performance improvements can be weighed against each other when choosing which approach to use. For applications that require fast DOM manipulation, document.createElement() can be used. For applications where readability and simplicity are more important, the jQuery approach remains a good choice.
