前段时间做项目,需要把全国省市的两个XML文件整合成一个JSON格式的数据,手写的话觉得数据太多了,而且容易出错,于是就想到了用Ajax嵌套的方法来解决,就想平时用Ajax的方法直接嵌套,都会先读出外面Ajax的内容,然后才读取嵌套在Ajax里面的内容,后面经网上查找资料,加个async:false这个Ajax参数就行了,下面是贴代码:

<script type="text/javascript"> $(function () { $.ajax({ type: "get", url: "/XmlData/Provinces.xml", datatype: "xml", success: function (xml) { $("body").append("{"); $(xml).find("Provinces > Province").each(function (i) { $("body").append("{"PID":"" + $(this).attr("ID") + "","ProvinceName": "" + $(this).attr("ProvinceName") + "","Citys":["); //根据省份,请求读取该省的市 GetCitys($(this).attr("ID")); //第二个请求end $("body").append("]},<br/>"); }); } }); }) //第二次请求 function GetCitys(pid) { $.ajax({ type: "get", url: "/XmlData/Cities.xml", datatype: "xml", async: false,//注意!!这个为必要的参数,不然这个会在上面的Ajax请求后才执行 success: function (xml) { $(xml).find("Cities > City[PID=" + pid + "]").each(function (i) { $("body").append("{"CityID":"" + $(this).attr("ID") + "","CityName":"" + $(this).attr("CityName") + ""},"); }); } }); } </script>

记得在前面加上jq库,

下面把得到的全国省市的JSON数据贴出来,希望以后能用到:
