如何扩展jQuery的replaceWith函数来接受回调函数？

问题描述

这应该很容易，对吧？但我不能sem在任何地方找到这样的功能的任何示例。问题是，在我做一个replaceWith（）之后，我想对那些写入DOM的元素做一些事情，但如果我尝试在replaceWith（）调用之后对它们做一些事情，他们不存在我需要确保replaceWith（）完全完成。我只想让这样的工作：

This should be easy, right? Yet I can't sem to find any examples of such a functionality anywhere. The problem is that after I do a replaceWith() I want to then do something with those elements that were written to the DOM, but if I try to do something to them right after the replaceWith() call they don't exist yet so I need to be sure the replaceWith() is completely finished. I just want something like this to work:

$('#foo').replaceWith('some text', function() {
     //do something else here
});

想法？

推荐答案

您可以自己调用 replaceWith 的函数：

You can make your own function that calls replaceWith:

$.fn.replaceWithCallback = function(replace, callback){
    var ret = $.fn.replaceWith.call(this, replace); // Call replaceWith
    if(typeof callback === 'function'){
       callback.call(ret); // Call your callback
     }
    return ret;  // For chaining
};
