Javascript : Getting and Setting Caret Position in Textarea

December 27th, 2005 Leave a comment Go to comments
function doGetCaretPosition (ctrl) {
	var CaretPos = 0;	// IE Support
	if (document.selection) {
	ctrl.focus ();
		var Sel = document.selection.createRange ();
		Sel.moveStart ('character', -ctrl.value.length);
		CaretPos = Sel.text.length;
	// Firefox support
	else if (ctrl.selectionStart || ctrl.selectionStart == '0')
		CaretPos = ctrl.selectionStart;
	return (CaretPos);
function setCaretPosition(ctrl, pos){
	else if (ctrl.createTextRange) {
		var range = ctrl.createTextRange();
		range.moveEnd('character', pos);
		range.moveStart('character', pos);

Here “ctrl” is the Textarea object. This script works well with Internet Explorer, Firefox and Opera.

    “me too”. I see tinyMce uses this kind of function and I was looking to replicate the behaviour in other input fields.

    This is not working in IE10. I wants to get current position of cursor in text area. :(

    For getting the correct position in IE10, you need to use the code in the “else if” section (with the “firefox support” comment) in the example. If you want to use the snippet from the example in IE10 change your if statement into the following:

    // IE, but not IE10
    if (document.selection && navigator.appVersion.indexOf(“MSIE 10″) == -1) {
    // Normal browsers and IE10
    else if (ctrl.selectionStart || ctrl.selectionStart == ’0′)

    It works like a charm. I have tried many codes before you. Yours is super.

    keep up the good work.

    Hi guys,

    i writting here after many hours of trying. So i will appreciate any kind of help. I have a big problem with IE.

    When i apply the code above so as it is it work perfect. But if i call function doGetCaretPosition() after blur or keydown or keyup or click on textare it begins to behave “irrationally” showing wrong results (in text but if the cursor is on the end of a text it works correct).

    Any ideas why? Thanks.
