在jsfiddle中,他们可以选择在左侧选项中设置no wrap(head)
,no wrap(body)
,OnDomReady
和OnLoad
。在我的程序中设置no wrap(head)
条件。它的工作很好。但我如何更改为HTML文件。我需要在HTML文件中设置相同的条件
演示:JSFIDDLE
我在这里设置no-wrap(head)
,如何设置HTML文件的条件与no-wrap(head)
相同?。
这是我的完整代码
<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,
width: 400,
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>

这只是意味着该脚本已添加到<head>
<html>
部分
no wrap(head):不要包装JavaScript代码,将其放在
<head>
中 节
