Question

我有一个PhoneGap应用程序，它接受用户提示值并将该参数上传到我的公司服务器。启动一个流程，创建一个图表并将其返回给应用程序。脚本进入console.log（）语句，但executeSQL函数不起作用。我将数据库声明在顶部，所以我不确定我错过了什么。我没有收到任何错误，但价值没有传递给

var locationStr;

      window.gp_chart = new Geoprocessor("http://ourserver.com/arcgis/rest/services/Three_Week_Chart/GPServer/ThreeWeekChart");

      var link = domConstruct.create("a",{
            "class": "action", 
            "id": "chartLink",
            "innerHTML": "Three Week Chart", //text that appears in the popup for the link 
            "href": "javascript: void(0);"
          }, query(".actionList", map.infoWindow.domNode)[0]);

      on(link, "click", function()
            { 


             // database setup

嗯，这很有效。

var locationStr;

      window.gp_chart = new Geoprocessor("http://ourserver.com/arcgis/rest/services/Three_Week_Chart/GPServer/ThreeWeekChart");

      var link = domConstruct.create("a",{
            "class": "action", 
            "id": "chartLink",
            "innerHTML": "Three Week Chart", //text that appears in the popup for the link 
            "href": "javascript: void(0);"
          }, query(".actionList", map.infoWindow.domNode)[0]);

      on(link, "click", function()
            { 

            window.navigator.notification.prompt(
              "Enter Location Name: ", // message
              handleLocationPrompt, // callback
              "Add location", //title
              ["Ok", "Exit"] // button titles
            );

            // handle user's dialog action
            function handleLocationPrompt(results) {
              if (results.buttonIndex === 1) {
                // Ok
                locationStr = results.input1

                var lat,lon = "";
             lat = x.toString();
             lon = y.toString();

            var taskParams = {
              "Latitude": lat,
              "Longitude": lon,
              "Location": locationStr

            };
              domAttr.set(dom.byId("chartLink"), "innerHTML", "Generating Chart...");
              window.gp_chart.execute(taskParams, gpChartResultAvailable, gpChartFailure);


              }
            }
