问题 I am having a bit of difficultly re the auto complete function in code mirror. What I am trying to do is two things (both which I am struggling with): 1) I want to enable auto complete for both HTML and JavaScript . Currently I can only get one working at a time using e.g.: CodeMirror.commands.autocomplete = function (cm) { CodeMirror.showHint(cm, CodeMirror.hint.html); }; How can I add the CodeMirror.hint.javascript to the list from the HTML one? 2) (Kind of more important) -- How can I add

问题 I'm using CodeMirror autocomplete in python mode (python-hint.js). I've customized the keyword list by adding my list. But it raises the case sensitive issue by not retrieving the capital keywords when providing keyword in small letter. Please where to make changes in python-hint.js file to make the search case in sensitive. Any help or suggestion is appreciated. 回答1: You can implement the case-insensitive autoComplete feature by adding the following lines in Python-hint.js -> function

问题 Here's jsfiddle --> http://jsfiddle.net/uTy5j/7/embedded/result/ I'm using CodeMirror and it seems that Codemirror is erasing my style tag that I create with: var preview = document.getElementById('preview'); var mypreview = preview.contentDocument; mypreview.open(); mypreview.close(); var style = document.createElement('style'); style.id = 'mycssid'; style.type ='text/css'; mypreview.head.appendChild(style); Can anyone figure out how I can get this style tag appended to the head of the

问题 How I can save() all CodeMirror textareas on one page? 回答1: You'd have to cache all CodeMirror instances in to an array, and then loop through that array save() 'ing each instance. var CMInstances = [instance1, instance2, ..., instanceN]; for (instance in CMInstances) { instance.save(); } I'd assume at some point in your script you're setting up your CodeMirror instances, so that point would be ideal to cache them. 来源： https://stackoverflow.com/questions/7463644/save-all-codemirrors-on-page

问题 I'm using CodeMirror along with jQuery to provide syntax highlighting on a pet PoC project. It's been doing great, until I realized that CodeMirror seems to be capturing key press events on the DOM in such a way that it stops global application hotkeys from working when I'm currently typing into a CM-enabled textarea. For simplicity's sake, let's assume that I have the following listener on my page: var hotkey = function (e) { if (e.shiftKey) { alert('foo'); } }; $(document).keypress(hotkey);

问题 Anbody does have an solution for a min lines number - in Codemirror? min-height worked for me but do not insert empty lines for the height. JS var editor = CodeMirror.fromTextArea(document.getElementById("code"), { lineNumbers: true, gutter: true, lineWrapping: true }); CSS .CodeMirror-scroll { overflow: auto; height: auto; overflow: visible; position: relative; outline: none; min-height: 300px; /* the minimum height */ } Maybe there is a simple solution to insert empty lines for that ? 回答1:

问题 I'm trying to find a way to test if the cursor is preceded by a specific string and then trigger an event. Example of what I'm trying to do: User clicks somewhere inside the editor, a cursorActivity (cursor or editor changed) event is fired, I catch the event and test whether or not the previous 6 characters matches the string 'color:' If so then do I something. I can't seem to find any kind of method that lets you actually read directly from the editor though, aside from catching the

问题 I want my TextArea to be able to support multiple CodeMirror modes. For now I want it to support json and xml. Is this possible? Also, is it possible to automatically detect whether the user placed json or xml in the area? Thanks. 回答1: CodeMirror actually has an example very close to what you are looking for here. Here is a more specific example that does what you want. Create a CodeMirror instance. When the content changes we determine if we should switch modes. The logic I put in for
