问题描述
我已将 CodeMirror 与以下代码集成在一起,
I have integrated CodeMirror with below code,
<style>
.CodeMirror {
border-top: 1px solid #888;
border-bottom: 1px solid #888;
}
</style>
<body>
<textarea id="myCode"></textarea>
<script type="text/javascript">
window.onload = function() {
var myTextarea = $("#myCode")[0];
editor = CodeMirror.fromTextArea(myTextarea, {
lineNumbers: true
});
};
</script>
</body>
它仅显示普通的文本区域,看起来不像编辑器,并且行号丢失.如果我缺少任何东西,请帮助我.
It shows a normal textarea only, which doesn't look like an editor and the line numbers are missing. Please help me if anything I am missing.
当我将 var myTextarea = $(#myCode");
行替换为 var myTextarea = $(#myCode")[0]
时,将显示编辑器也是如此.
When I replace the line var myTextarea = $("#myCode");
with var myTextarea = $("#myCode")[0]
, it displays the edotor as well.

HTML:
<textarea id="code"></textarea>
JS:
var minLines = 5;
var startingValue = '';
for (var i = 1; i < minLines; i++) {
startingValue += '\n';
}
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
lineNumbers: true,
gutter: true,
lineWrapping: true,
value: startingValue
});
//FIX FOR MIN LINES
