我提出了通过AJAX可以加载新的设置页面，我不知道什么是从新的内容页面绑定听众的内容，其中最有效的方法什么？

I am making something that can loads new setting pages via AJAX, I am not sure what's the most efficient way to bind listeners to those elements from the new content page?

下面是我的想法。我可以做一个功能比较文件的路径，并为每个条件，那么我会正确的监听器适用于基于什么页面，AJAX加载这些新的元素。我觉得这将使得功能如此之大，如果我有大量的页面。

Here's my thought. I can make a function that compares file path, and for each condition, then I will apply correct listeners to those new elements based on what page that AJAX loaded. I feel like it will makes the function so big if I have a large amount of pages.

谢谢！

推荐答案

有两种方式：

1）使用非动态父容器绑定。对（）

1) Bind on a non-dynamic parent container using .on()

$('.some-parent-class').on('click', '.element', function() {
  // DO STUFF!
});

2）绑定新的元素Ajax调用完成后，

2) Bind the new elements after ajax call is completed

$.ajax(url, {
  // ajax options
}).done( function(data) {
  var newEl = $('<div class="element"></div>');
  // Setup your newEl with data here...
  newEl.on('click', function() {
    // do stuff
  });
  newEl.appendTo($('.some-parent-class'));
});

，前者通常会导致更快的Ajax响应时间，但可以也慢点击响应速度下降。

The former usually results in quicker ajax response times, but may also slow click responsiveness down.
