Question

我试图让用户编辑 html / css ，但阻止他们进行在 <？php 块

中修改代码

到目前为止，我一直在测试codemirror，并能够通过将 markText 与只读参数一起使用，可以获得预期的结果。

我想知道是否有其他方法或不同的方法基于浏览器的编辑器？

这是我的例子：

window.onload = () => {
	// js syntax
	function init(ok) {
		return ok;
	}
}
var htmlEditor = CodeMirror.fromTextArea(document.getElementById("code"), {
	lineNumbers: true,
	mode: "htmlmixed",
	theme: 'default'
});
htmlEditor.markText({line:4,ch:1},{line:7,ch:1},{readOnly:true});

下面是整个代码段，可防止 <？php 块被编辑
