使用 CodeMirror。我无法让 getCursor() 函数工作。我有一个带有代码镜像源的 jsFiddle。
---->看这里 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() 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.
});
});
