Originally posted this here: Trying to load Google charts through a (jQuery)ajax call but have modified my code a bit but I still can't get it to work properly.

我想写一个民意调查功能加载的结果，并在同一个页面无刷新显示。我使用谷歌图表API和jQuery阿贾克斯。

I am trying to write a poll function that loads the results and displays it in the same page without refreshing. I am using google charts api and jquery ajax.

主网页我有这样的：

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
    google.load('visualization', '1.0', {'packages':['corechart']}); // Load the Visualization API and the piechart package.
    google.setOnLoadCallback(function(){  $("#poll_yes").removeAttr('disabled'); });

    function drawChart(rows) 
    {
        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Answers');
        data.addColumn('number', 'Number');
        data.addRows(rows);


        // Set chart options
        var options = 
        {
            'title'             :'Do you Like my poll?',
        };

        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);              
    }       

    jQuery(document).ready(function() {
        $.ajaxSetup ({  
            cache: false  
        }); 
        var ajax_load = "<img src='images/loading.gif' alt='loading...' />";  

        $("#poll_yes").click(function(){
            $("#result").html(ajax_load); 
            $.post(
                "query.php",  
                {answer: "yes", poll_id: 5},  
                function(response){ 
                    drawChart(response);
                }
            );
        });                 
    }); 
</script>
<input type="submit" value="yes" disabled="disabled" id="poll_yes"/>
<div id="result"><div id="chart_div">&nbsp;</div></div>

目前在我的query.php页的momemnt我只是有它吐出假JSON数据：

At the momemnt in my query.php page I just have it spitting out fake JSON data:

<?php 

if(isset($_POST['answer']))
{
    echo "{\"yes\": 14,\"no\": 9}";
}
else
{
    echo "{\"yes\": 9,\"no\": 14}";
}
?>

在我打的是按钮，它的作用是显示ajaxloader.gif形象。

After I hit the 'yes' button all it does is show the ajaxloader.gif image.

我感觉非常沮丧，并不能为我的生命弄清楚为什么发生这种情况。任何帮助是AP preciated =）

I'm feeling very frustrated and cannot for the life of me figure out why this is happening. Any help is appreciated =)

推荐答案

您原来的code：

google.load('visualization', '1.0', {'packages':['corechart']}); // Load the Visualization API and the piechart package.

添加一个参数，它应该是确定：

add one more parameter and it should be OK:

google.load('visualization', '1.0', {'packages':['corechart'], **"callback": drawChart**});
