CodeMirror getCursor（）无法正常工作？(CodeMirror getCursor() not working? JQuery Javascript)

使用CodeMirror。我无法使getCursor（）函数工作。我有一个附加了codemirror源的jsFiddle。

----> 看到这里JSfiddle <----

我正在尝试将文本插入编辑器，然后强制光标向后移动指定数量的空格。我只是想用getCursor（）来获取光标位置，但我似乎无法让它工作。有什么想法吗？

$(document).ready(function() { //Changing the textarea to a CodeMirror rich text editor var editor = CodeMirror.fromTextArea(document.getElementById('theZone'), { mode: 'text/html', lineWrapping : true, lineNumbers : true, extraKeys : { "Tab": "indentMore", "Shift-Tab": "indentLess", "'>'": function(cm) { cm.closeTag(cm, '>'); }, "'/'": function(cm) { cm.closeTag(cm, '/'); } } , onCursorActivity: function(cm) { cm.setLineClass(hlLine, null, null); hlLine = cm.setLineClass(cm.getCursor().line, null, "activeline"); } }); //When SELECT changes - insert the value into the CM editor, set focus, get cursor position, move cursor back [x] amount of spaces. $('#sel').change(function() { var selected = $(this).find('option:selected'); var mynum = selected.data('val'); editor.replaceSelection($(this).val(), focus); editor.focus(); var start_cursor = editor.getCursor(); //I need to get the cursor position alert(start_cursor); //Cursor position always comes up [object Object] //write code to move cursor back [x] amount of spaces. [x] is the data-val value. }); });

Using CodeMirror. I cannot get the getCursor() function to work. I have a jsFiddle with codemirror sources attached.

I'm trying to insert text into the editor, then force the cursor to move back a specified number of spaces. I'm just trying to get the cursor location with getCursor() but I can't seem to get it to work. Any thoughts?

代码似乎工作得很好。 alert（）不会显示对象。请改用console.log（）。我添加了其余的代码。

$('#sel').change(function() { var selected = $(this).find('option:selected'); var mynum = selected.data('val'); editor.replaceSelection($(this).val(), focus); editor.focus(); var start_cursor = editor.getCursor(); //I need to get the cursor position console.log(start_cursor); //Cursor position var cursorLine = start_cursor.line; var cursorCh = start_cursor.ch; //Code to move cursor back [x] amount of spaces. [x] is the data-val value. editor.setCursor({line: cursorLine , ch : cursorCh -mynum }); });

The code seems to work just fine. alert() will not display objects. use console.log() instead. I added the rest of the code.
