<!-- 引入jQuery -->

$(function(){

$('#send').click(function() {

$.ajax({

type: "GET",

url: "test.js",

dataType: "script"

});

//共用这2个全局的ajax事件

$("#loading").ajaxStart(function(){

$(this).show();

});

$("#loading").ajaxStop(function(){

$(this).hide();

}); //ajaxStart ajaxStop 好处 :在请求的过程中阻止用户操作,比如可以在ajax请求的过程中进行一些遮罩,
