我已经使用下面的方法来查看修改 textarea 区域时的输出,它工作正常。但是我想使用 Codemirror 作为 textarea,当我在 codemirror textarea 中插入任何数据时,输出应该出现 div 。
<script type="text/javascript">
function updateDisplay() {
document.getElementById("code").innerHTML = document.getElementById("entry").value;
}
</script>
<textarea onkeyup="updateDisplay();" name="entry" id="entry" cols="1000" rows="500"></textarea>
<div name="code" id="code" ></div>
代码镜像
<link rel="stylesheet" href="http://codemirror.net/lib/codemirror.css">

<textarea id="code" name="code">
<html style="color: green">
<!-- this is a comment -->
<style type="text/css">
h1 {font-family: comic sans; color: #f0f;}
div {background: yellow !important;}
body {
max-width: 50em;
margin: 1em 2em 1em 5em;
}
</style>
</head>
<body>
<script>
function jsFunc(arg1, arg2) {
if (arg1 && arg2) document.body.innerHTML = "achoo";
}
</script>
</body>
</html>
</textarea></form>
<script>
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {mode: "text/html", tabMode: "indent"});
</script>
