jquery事件不会在通过load()加载的内容上触发

.live() .delegate()

$("table").delegate("tr", "click", function() {
  //do something, the table row is this, for example:
  $(this).toggleClass("selected");
});

<table> bubble up <tr>

$(".something").live("click", function() {
  $(this).toggleClass("selected");
});

document
