在jsfiddle中,他们有选择在左侧选项中设置wrap(head),no wrap(body),OnDomready和OnLoad.在我的程序中设置没有包装(头)条件.它的工作很好但是我如何更改为
HTML文件.我需要在我的
HTML文件中设置相同的条件
演示：JSFIDDLE
这里我设置no-wrap(头),我如何设置HTML文件与no-wrap(head)相同的条件？
这里我的完整代码
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="a.js"></script>
<script type="text/javascript">
google.load('visualization','1',{packages: ['corechart']});
google.setonLoadCallback(drawVisualization);
function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['Country','Popularity'],['Germany',200],['United States',300],['Brazil',400],['Canada',500],['France',600],['Russia',700]
]);
// this chart is drawn in a visible div and then immediately hidden
var chart1 = new google.visualization.PieChart(document.getElementById('chart_1'));
google.visualization.events.addListener(chart1,'ready',function () {
// hide the div when done drawing
document.getElementById('chart_1').style.display = 'none';
// create an event listener for the button that shows the chart
document.getElementById('clickMe1').onclick = function () {
document.getElementById('chart_1').style.display = 'block';
}
});
// show the div before you draw
document.getElementById('chart_1').style.display = 'block';
chart1.draw(data,{
height: 300,width: 400,title: 'Chart 1'
});
// this chart only gets drawn when the button is clicked
var chart2 = new google.visualization.PieChart(document.getElementById('chart_2'));
// create an event listener for the button that shows the chart
document.getElementById('clickMe2').onclick = function () {
document.getElementById('chart_2').style.display = 'block';
chart2.draw(data,{
height: 300,title: 'Chart 2'
});
}
}
</script>
<style type="text/css">
#visualization path {
cursor: pointer
}
</style>
</head>
<body>
<input type="button" value="Show chart 1" id="clickMe1" />
<input type="button" value="Show chart 2" id="clickMe2" />
<div id="chart_1" style="display: none"></div>
<div id="chart_2" style="display: none"></div>
</body>
</html>
谢谢你的建议.
解决方法
这只是把你的JavaScript放在< head>标签
