我有一个控制器,它以Google Charts预期的格式返回(很好)格式化的JSON。我可以通过导航到http://localhost:9000/manager/echoVariables
查看输出,并且OP如下所示:[["foo",3],["foo",3]]
如何使用AJAX查询动态填充Google图表,获取DOM异常8
我想要做一个AJAX调用,并且不能将此JSON传递给Google Charts。我可以确认收到的是JSON,我在Chrome的浏览器检查器的“网络”选项卡中进行了验证。
但是我在将这个JSON字符串传递给Google Charts的过程中收到DOM Exception 8
。
这是创建图形视图:
#{extends 'main.html' /} #{set title:'Home' /} #{set 'moreScripts'}
#{/set}
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
<script type="text/javascript">
//$.get()
$(document).ready(function() {
$("#result").html();
$.get(
'/manager/echoVariables',
{var1: "foo", var2: 5},
function(responseText){
$("#result").html(responseText);
},
"json"
);
});
</script>
<body>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
<div id="result"></div>
</body>
如何使饼图显示我的价值观,而不是在该段给出的那些?
谢谢。
谢谢杰夫,我会试试看。 – theTuxRacer 2013-02-28 07:10:01
是的杰夫,我能够做到。 JS不是我的特长,我想知道你是否会帮我清理它? – theTuxRacer 2013-02-28 08:01:16
