Php jQuery+；JSON+；打开flash chart，如何动态创建图表？

JS

使用firebug，如果我对返回的JSON进行硬编码，图表就可以正常工作。但是，当我像上面那样请求数据时，即在页面加载之后，我得到一个2032错误

---

getMyData方法实际上是从PHP脚本请求数据，而PHP脚本又从外部API（像flickr这样的大型API）请求数据，因此如果我们当前没有缓存结果，可能会有几秒钟的延迟。可能是我弄错了？

只是一个猜测，因为我不使用Open Flash Chart，但由于您正在进行异步ajax调用，因此getMyData函数实际上没有返回json值（您定义的回调函数是）

---

尝试预加载（可能在swf嵌入之前进行同步ajax调用？）数据并将其存储在var中，然后让getMyData函数简单地返回该var。

您必须将swfobject.embedSWF（）放入ajax回调中

像这样：

SWFlocation = "open-flash-chart.swf";
getMyData = function()
{
    $.post(
        myJsURL, 
        {
            passedval: 1234
        }, 
        function (returned_json) {
            return returned_json;

        },
        "json"
    ); 
}
swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":"getMyData"} );

function ajaxchart() {
  $.ajaxSetup({async : false});
  var chart = '';
  var url = "data.php";
  var data = '';
  var callback = function(resp) {
    chart = resp;
  };
  $.post(url, data, callback, 'text');
  return chart;
}
$(function() {
  $("#test").click(function() {
    swfobject.embedSWF("open-flash-chart.swf", "my_chart", "350", "200", "9.0.0", "expressInstall.swf", {"get-data":"ajaxchart"});
  });
});

 function open_flash_chart_data(){
     return JSON.stringify(data);
     }

  });
});

 function open_flash_chart_data(){
     return JSON.stringify(data);
     }

调用

$.post（）；

范例

SWFlocation = "open-flash-chart.swf";
init_chart = function()
{
    $.post(
        myJsURL, 
        {
                passedval: 1234
        }, 
        function (returned_json) {
                swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":returned_json} );    
        },
        "json"
    ); 
}
init_chart();

调用

范例

SWFlocation = "open-flash-chart.swf";
init_chart = function()
{
    $.post(
        myJsURL, 
        {
                passedval: 1234
        }, 
        function (returned_json) {
                swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":returned_json} );    
        },
        "json"
    ); 
}
init_chart();

在Javascript中，像这样声明变量

flashvars

和变量

data

：

SWFlocation = "open-flash-chart.swf";
getMyData = function()
{
    $.post(
        myJsURL, 
        {
            passedval: 1234
        }, 
        function (returned_json) {
            return returned_json;

        },
        "json"
    ); 
}
swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":"getMyData"} );

function ajaxchart() {
  $.ajaxSetup({async : false});
  var chart = '';
  var url = "data.php";
  var data = '';
  var callback = function(resp) {
    chart = resp;
  };
  $.post(url, data, callback, 'text');
  return chart;
}
$(function() {
  $("#test").click(function() {
    swfobject.embedSWF("open-flash-chart.swf", "my_chart", "350", "200", "9.0.0", "expressInstall.swf", {"get-data":"ajaxchart"});
  });
});

 function open_flash_chart_data(){
     return JSON.stringify(data);
     }

另外，请确保您拥有此函数，该函数由swfobject.embedSWF自动调用：

var flashvars = {};
var data;

现在转到AJAX函数并更改AJAX成功调用，如下所示：

SWFlocation = "open-flash-chart.swf";
getMyData = function()
{
    $.post(
        myJsURL, 
        {
            passedval: 1234
        }, 
        function (returned_json) {
            return returned_json;

        },
        "json"
    ); 
}
swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":"getMyData"} );

function ajaxchart() {
  $.ajaxSetup({async : false});
  var chart = '';
  var url = "data.php";
  var data = '';
  var callback = function(resp) {
    chart = resp;
  };
  $.post(url, data, callback, 'text');
  return chart;
}
$(function() {
  $("#test").click(function() {
    swfobject.embedSWF("open-flash-chart.swf", "my_chart", "350", "200", "9.0.0", "expressInstall.swf", {"get-data":"ajaxchart"});
  });
});

 function open_flash_chart_data(){
     return JSON.stringify(data);
     }

我遇到了一个类似的问题，很难调试成功回调中同时需要变量

data

和

flashvars

。如果这些变量（或

函数打开\u flash\u chart\u data（）

）如果缺少，您将得到错误2032。

在Javascript中，声明变量

flashvars

和变量

数据如下：

SWFlocation = "open-flash-chart.swf";
getMyData = function()
{
    $.post(
        myJsURL, 
        {
            passedval: 1234
        }, 
        function (returned_json) {
            return returned_json;

        },
        "json"
    ); 
}
swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":"getMyData"} );

function ajaxchart() {
  $.ajaxSetup({async : false});
  var chart = '';
  var url = "data.php";
  var data = '';
  var callback = function(resp) {
    chart = resp;
  };
  $.post(url, data, callback, 'text');
  return chart;
}
$(function() {
  $("#test").click(function() {
    swfobject.embedSWF("open-flash-chart.swf", "my_chart", "350", "200", "9.0.0", "expressInstall.swf", {"get-data":"ajaxchart"});
  });
});

 function open_flash_chart_data(){
     return JSON.stringify(data);
     }

另外，请确保您拥有此函数，该函数由swfobject.embedSWF自动调用：

var flashvars = {};
var data;

        }, 
        function (returned_json) {
            return returned_json;

        },
        "json"
    ); 
}
swfobject.embedSWF(SWFlocation, "myChartDiv", "650", "200", "9.0.0", "", {"get-data":"getMyData"} );

function ajaxchart() {
  $.ajaxSetup({async : false});
  var chart = '';
