我正在尝试使用jQuery easyui布局功能将区域内的按钮居中:
<!DOCTYPE html>
<html style="height: 90%;">
<head>
<meta charset="UTF-8">
<title>The Analytic Platform - Home Page</title>
<link rel="stylesheet" type="text/css" href="../themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="../themes/icon.css">
<link rel="stylesheet" type="text/css" href="demo.css">
<script type="text/javascript" src="../jquery.min.js"></script>
<script type="text/javascript" src="../jquery.easyui.min.js"></script>
<style>
.middle {
height:30%;
}
.topandbelow {
height:40%;
}
</style>
</head>
<body style="height: 90%;">
<h2>The Analytic Platform</h2>
<p>Easy analytics for everyone!</p>
<div id="p" class="easyui-panel" title="Step 1: Load data for analysis" style="width:100%;height:100%;padding:10px;">
<div class="easyui-layout" data-options="fit:true" style="width:100%;height:100%">
<div data-options="region:'west',split:false,border:true" style="width:40%;" title="Get data from Excel file">
<div class="easyui-layout" data-options="fit:true" style="width:100%;height:100%">
<div data-options="region:'centre',split:false,border:true" style="width:100%;">
<a href="ExcelUpload.html" class="easyui-linkbutton" >Upload Excel file</a>
</div>
</div>
</div>
<div data-options="region:'east',split:false,border:true" style="width:40%;height:100%" title="Get data from database">
<div class="easyui-layout" data-options="fit:false" style="width:100%;height:100%">
<div data-options="region:'north',split:false,border:true" class="topandbelow"></div>
<div data-options="region:'centre',split:false,border:true" class="middle">
<a href="DefineDBconnection.html" class="easyui-linkbutton">Define Database Connection</a>
</div>
<div data-options="region:'south',split:false,border:true" class="topandbelow"></div>
</div>
</div>
</div>
</div>
</body>
</html>
“东”区域未显示其嵌套的“中心”区域,其中“北”区域覆盖它。
这里可能出现什么问题?
