我有一個控制器,它以Google Charts預期的格式返回(很好)格式化的JSON。我可以通過導航到http://localhost:9000/manager/echoVariables
查看輸出,並且OP如下所示:[["foo",3],["foo",3]]
如何使用AJAX查詢動態填充Google圖表,獲取DOM異常8
我想要做一個AJAX調用,並且不能將此JSON傳遞給Google Charts。我可以確認收到的是JSON,我在Chrome的瀏覽器檢查器的「網絡」選項卡中進行了驗證。
但是我在將這個JSON字符串傳遞給Google Charts的過程中收到DOM Exception 8
。
這是創建圖形視圖:
#{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>
如何使餅圖顯示我的價值觀,而不是在該段給出的那些?
謝謝。
謝謝傑夫,我會試試看。 – theTuxRacer 2013-02-28 07:10:01
是的傑夫,我能夠做到。 JS不是我的特長,我想知道你是否會幫我清理它? – theTuxRacer 2013-02-28 08:01:16
