研究textarea自适应高度的,发现有些是通过div来模拟的,测试下也还可行。摘抄了一个例子。
- <html>
- <meta http-equiv="content-type" content="text/html;charset=utf-8">
- <title>div模拟textarea实现高度自适应</title>
- <head>
- <style>
- .test_box {
- width: 400px;
- min-height: 20px;
- max-height: 300px;
- _height: 20px;
- margin-left: auto;
- margin-right: auto;
- padding: 3px;
- outline: 0;
- border: 1px solid #a0b3d6;
- font-size: 18px;
- word-wrap: break-word;
- overflow-x: hidden;
- overflow-y: auto;
- _overflow-y: visible;
- }
- </style>
- </head>
- <body>
- <div contenteditable="true" class="test_box"></div>
- </body>
- </html>
