jquery 发送 json 格式的两个步骤

jquery 发送 json 格式的两个方法
这段时间，前台使用了jquery，来做一些开发，做了两个发送json格式的数据的请求，感觉有些启发。

var connect = {      /**     * 同步发送参数，服务器端@RequestParam，接收参数     * @param action     * @param method     * @param params     */    sendParamSync : function (action, method, params) {        var ret        $.ajaxSetup({async:false});        $.getJSON(this._basePath + action + "/" + method + ".do", params,          function(res, state) {               if (state == 'success') {                  ret = res;               }        })        return ret;    },    /**     * 异步发送参数，服务器端@RequestParam，接收参数     * @param action     * @param method     * @param params     */    sendParamAsync : function (action, method, params) {        var ret        $.ajaxSetup({async:true});        $.getJSON(this._basePath + action + "/" + method + ".do",params,         function(res, state) {               if (state == 'success') {                  ret = res;               }        })        return ret;    }}

   $.ajaxSetup({async:true});

   传递的参数是一个json格式的串，$.ajaxSetup，是设置ajax的环境变量的。
  

      jQuery.extend( jQuery.ajaxSettings, settings );   

    而 jQuery.ajaxSettings，看了一看jquery的源代码代码
   

ajaxSettings: {url: location.href,global: true,type: "GET",contentType: "application/x-www-form-urlencoded",processData: true,async: true,/* * timeout: 0, data: null, username: null, password: null, */// Create the request object; Microsoft failed to properly// implement the XMLHttpRequest in IE7, so we use the ActiveXObject when// it is available// This function can be overriden by calling jQuery.ajaxSetupxhr:function(){return window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();},accepts: {xml: "application/xml, text/xml",html: "text/html",script: "text/javascript, application/javascript",json: "application/json, text/javascript",text: "text/plain",_default: "*/*"}}
