问题描述
在页面加载时，codemirror是否可以突出显示与模式匹配的代码（例如，如果我使用搜索插件）？因此，我可以使用？search = my_pattern加载页面，并将该模式传递给codemirror。
Is there a way for codemirror to highlight the code matching a pattern (like if I use the search addon) when the page load? So I could load the page with ?search=my_pattern and pass the pattern to codemirror.
这是示例代码和jsfiddle。您可以使用CTRL + F来使用搜索插件。
Here's a sample code and a jsfiddle. You can use CTRL+F to use the search addon.

推荐答案
我想出了如何使用
I figured out how to do it using overlay.js by looking at the CodeMirror: Overlay Parser Demo.

<textarea id="myTextArea">print "hello world"</textarea>
<script>
var keyword = 'hello';
CodeMirror.defineMode("highlightSearch", function(config, parserConfig) {
var searchOverlay = {
token: function(stream, state) {
if (stream.match(keyword)) {
return "highlightSearch";
}
while (stream.next() != null && !stream.match(keyword, false)) {}
return null;
}
};
return CodeMirror.overlayMode(CodeMirror.getMode(config, parserConfig.backdrop || "python"), searchOverlay);
});
var myTextArea = document.getElementById('myTextArea');
var myCodeMirror = CodeMirror.fromTextArea(myTextArea, {
'mode': 'highlightSearch',
'lineNumbers': true
});
