Question

我有以下AJAX函数，它将访问ASMX Web服务并生成JSON响应。 JSON正在顺利生成。我想将这个生成的JSOn传递给另一个函数中的外部变量。

function setJsonSer() {
                         var strWsUrl = 'https://www.googleapis.com/analytics/v3/data/ga?   
ids=ga%3A76546294&dimensions='+ 'ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-
date='+retStartDate()+'&end-date='+retEndDate()+'&max-results=10';
    formData = {
            'Email': 'clientlink@client.com',
            'Password': 'password',
            'URL': strWsUrl
        };
             $.ajax({
            url: "/APIWebService.asmx/AnalyticsDataShowWithPost",
            type: 'POST',
            data: formData,

            complete: function(data) {
                      var responseText = data.responseText;
        /****01****/  var responseJson = JSON.parse(responseText.match(/[{].*.[}]/));
          console.log(responseJson);

                      Load(JSON.stringify(responseJson));
            }
        });
    }

你可以看到/ **** 01 **** /显示JSON响应正在传递到同一个函数中的另一个变量。我尝试了'return'语句，但没有用。那么我该怎么做才能解决这个问题呢？你能有人解决这个问题吗？

更新

我想将这个responseJson传递给下面的函数Load（）。它应该替换rowData值。那你们有什么建议我的呢？

function Load(){

// --------------------------------------------- - 罗汉

 var labels = new Array();
        var values = new Array();
        var catogories = new Array();
        var arrayOfArray = new Array();


        var rowData = ??????????????;
    console.log("'RowData' is " + typeof rowData );  

        inData = JSON.parse(rowData);

        var count = 0;
        var headers = new Array();
        for (var i = 0; i < inData.columnHeaders.length; i++) {
            headers[i] = inData.columnHeaders[i].name;
        }

        var dates = new Array();
        var pageViews = new Array();
        var uniqueViews = new Array();
        for (var key in inData.rows) {

                dates[key] = inData.rows[key][0];

            pageViews[key] = parseInt(inData.rows[key][1]);
            uniqueViews[key] = parseInt(inData.rows[key][2]);

        }

        $('#container_2').highcharts({
            chart: {

                    color: 'rgba(68, 170, 213, .2)'
                }]
            },

                enabled: false

            plotOptions: {

            series: [{

            }]
        });
}

应该使用CallBack功能

function functionWantToCallAjax()
{
      //Do some Operation
      setJsonSer(function(value){ //Do what u want to do with returned value });
}

function setJsonSer(callback) {
  var strWsUrl = 'https://www.googleapis.com/analytics/v3/data/ga?   
  ids=ga%3A76546294&dimensions='+ 'ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-
  date='+retStartDate()+'&end-date='+retEndDate()+'&max-results=10';
  formData = {
        'Email': 'clientlink@client.com',
        'Password': 'password',
        'URL': strWsUrl
  };
  $.ajax({
   url: "/APIWebService.asmx/AnalyticsDataShowWithPost",
   type: 'POST',
   data: formData,
   complete: function(data) {
                  var responseText = data.responseText;
    /****01****/  var responseJson = JSON.parse(responseText.match(/[{].*.[}]/));
                  console.log(responseJson);


                  Load(JSON.stringify(responseJson));

                  //Call Back function  
                  callback(responseJson); 
        }
    });
}

从AJAX函数获取变量值到外部
