因为JS的for循环与ajax非同步运行,所以致使for循环结束了而ajax却还未执行,解决此方法有两种php
一、设置ajax参数async为false,即与js同步,默认是true(异步).html
这里首先引用$.Ajax()中 async 和success的官方的解释:jquery
async | Boolean | Default: true |
---|---|---|
By default, all requests are sent asynchronous (e.g. this is set to true by default). If you need synchronous requests, set this option to false. Note that synchronous requests may temporarily lock the browser, disabling any actions while the request is active. |
代码示例:ajax
for(int i=0;i<x;i++){异步
var html = $.ajax({
url: "some.php",
async: false
}).responseText;async
}this
2.采用递归循环的方法解决此问题url
function func(times){
if(times <= 0){
return;
} spa
$.get(url,data,function(){
times --;
func(times); //递归调用
});
}htm
func(5);
