问题描述
我想知道如何通过单击 html 按钮使用 Javascript 禁用和启用 HTML 表格上的突出显示.
I want to know how can I disable and enable the highlighting on an HTML table using Javascript by clicking an html button.
这是我的代码:
tabletest.html
<html>
<head>
<script type="text/javascript">
function disableTable() {
document.getElementbyId('tblTest').disabled = true;
}
function enableTable() {
document.getElementbyId('tblTest').disabled = false;
}
</script>
<style type="text/css">
table#tblTest {
width: 100%;
margin-top: 10px;
font-family: verdana,arial,sans-serif;
font-size:12px;
color:#333333;
border-width: 1px;
border-color: #666666;
border-collapse: collapse;
}
table#tblTest tr.highlight td {
background-color: #8888ff;
}
table#tblTest tr.normal {
background-color: #ffffff;
}
table#tblTest th {
white-space: nowrap;
border-width: 1px;
padding: 8px;
border-style: solid;
border-color: #666666;
background-color: #dedede;
}
table#tblTest td {
border-width: 1px;
padding: 8px;
border-style: solid;
border-color: #666666;
background-color: #ffffff;
}
</style>
</head>
<body>
<table id="tblTest">
<thead>
<tr>
<th>Name</th>
<th>Address</th>
</tr>
</thead>
<tbody>
<tr onMouseOver="this.className='highlight'" onMouseOut="this.className='normal'" >
<td>Tom</td>
<td>UK </td>
</tr>
<tr onMouseOver="this.className='highlight'" onMouseOut="this.className='normal'" >
<td>Hans</td>
<td>Germany</td>
</tr>
<tr onMouseOver="this.className='highlight'" onMouseOut="this.className='normal'" >
<td>Henrik</td>
<td>Denmark</td>
</tr>
<tr onMouseOver="this.className='highlight'" onMouseOut="this.className='normal'" >
<td>Lionel</td>
<td>Italy</td>
</tr>
<tr onMouseOver="this.className='highlight'" onMouseOut="this.className='normal'" >
<td>Ricardo</td>
<td>Brazil</td>
</tr>
<tr onMouseOver="this.className='highlight'" onMouseOut="this.className='normal'" >
<td>Cristiano</td>
<td>Portugal</td>
</tr>
</tbody>
</table>
<input type="button" onclick="disableTable();" value="Disable" />
<input type="button" onclick="enableTable()" value="Enable" />
</body>
</html>
每当我单击 Disable 按钮时，表格突出显示仍处于启用状态.我对这个有点陌生，所以我真的需要你的帮助.
Whenever I click the Disable button the table highlighting is still enabled.
I'm kinda new to this so I really need your help.

修复了您的代码.使用函数检查它是否被禁用，如果不是，则突出显示.如果是，那就不要.很简单.
Fixed your code. Use a function to check if it's disabled, if it isn't, then highlight. If it is, then don't. Simple enough.
