我第一次使用Google Charts。我已将饼图的基本示例复制到我的页面中,并在我的标题中包含了Google jsapi。
我已将以下代码添加到我的页面中:
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'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 and populate the data table.
var data = google.visualization.arrayToDataTable([
['Items', '# Items'],
['New', eval(new_items)],
['Current', eval(cur_items)],
['Retired', eval(ret_items)]
]);
// Create and draw the visualization.
new google.visualization.PieChart(document.getElementById('item_mix')).
draw(data, {title:"Items Status Mix"});
}
</script>
当我加载页面时,一切正常,图表显示和变量值确认数据。
然后我将Google代码包装在我自己的函数中并调用loadHQCharts();在主脚本的末尾。
<div id="item_mix"></div>
<script type="text/javascript">
function loadHQCharts() {
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart']});
.
.
}
</script>
<script type="text/javascript">
jQuery(document).ready(function(){
DO STUFF HERE...
loadHQCharts();
});
</script>
页面加载然后变为空白,其中一个空BODY并且在inspect / Firebug中没有错误。欢迎任何想法!

您可以删除jQuery(document).ready(function(){
包装并直接致电loadHQCharts
,它应该可以正常使用。
或删除google.setOnLoadCallback
功能并将callback
参数添加到第一行:
google.load("visualization", "1", {packages:["corechart"], callback: drawChart});
//remove: //google.setOnLoadCallback(drawChart);
