Note: In year 2020, this solution still works for textarea/input. The user selects a value from the dropdown list, clicks the Insert button, and the value is appended to the value in the textbox. Here is a working snippet of code to get and set the caret position in HTML textarea and textbox. Thank u once again. Example: This example implements the above approach. Specify the number of rows. So it is natural that I was initially confused by the results where it sometimes worked on a non-zero position. You are actually already doing it, but the reason your code isn't working properly might be, because you didn't close the "email"-input. } And for Arun : Works in chrome, no prob. var oldRange = document.selection.createRange (); …it worked perfectly, since I was then only counting line breaks between the caret and the end rather than all of them. There are a collection of attributes that can be applied to control a textarea's behavior. Thanks for this code,just what i need,This is one of the most useful scripts I’ve ever found. I missed this:, I have this:function getCursorPos(textElement){ var cursorPos = -1; if (textElement && textElement.createTextRange) { var range = document.selection.createRange().duplicate(); range.setEndPoint(‘StartToEnd’,range); var start = document.body.createTextRange(); start.moveToElementText(textElement); cursorPos = calcBookmark(range.getBookmark())-calcBookmark(start.getBookmark()); var rLen = 0; do{ var BrLen = rLen; rLen = newLine(textElement.value.substring(0,cursorPos + rLen + 1)); }while(BrLen!=rLen); cursorPos += rLen; } return cursorPos;}function calcBookmark(bk){ return (bk.charCodeAt(0)-1)+(bk.charCodeAt(3)-1)*65536+(bk.charCodeAt(2)-1);}It work’s for textarea in IE. (this.userAgent.indexOf(“Firefox”) == -1); }, Luckily there's a quick CSS solution to this problem! ‘userAgent’: navigator.userAgent, // Functions returning true or false Some developers also use cols and rows css property to provide textarea size. I tested this in on FF3.5/Ubuntu/Win, IE8/Win, Chrome 4.1/Win, Chrome 5/Ubuntu, Safari4/Win, Opera10.53/Win, I hope this helps someone out. ‘isIE’: function() { return ! selection is collapsed), you will see only single value. ‘isOpera’: function() { return ! This conversation has really helped point me in the right direction. } else if (keyCode == 38 || keyCode == 40) { The problem is Sel.moveStart (‘character’, -ctrl.value.length); which will move the selection to incorporate data not in the current control if there is any. As far as position argument for setStart and setEnd goes, it turned out that for textarea IE11 counts the number of text nodes and not characters inside of the textarea. break; but the the method the focus doesn’t move from the dropdown. Use offsetHeight to determine the TextArea height, scrollHeight to determine the total length of text in the textarea (in pixels) and scrollTop to set the position of the scrollbar like in the example below: evt = document.createEvent(“KeyboardEvent”); r.select(); The "selectionStart" property wasn't supported in all browsers when this question was posted. textarea { resize: none;} Now you can use height and width property to provide a fixed height and width to the element. In playing with the example (https://demo.vishalon.net/getset.htm), with IE 7, the cursor will go to the desired spot AND will scroll to the appropriate view. Also see the
tag.. Auto height can also automatically adjust its height (text rows) to fit the content, even as the user enters or deletes text. ‘version’: navigator.appVersion, control.focus(); return {start: el.selectionStart, end: el.selectionEnd}; do arrow-up-stuff : do arrow-down-stuff; Explaining moveEnd and moveStart The above code could then be updated to use the equivalent getSelectionRange of the textarea when a user clicks a button, insert your code, then move the cursor to the end of the newly inserted code. evt = document.createEvent(“KeyboardEvent”); So i will appreciate any kind of help. The following seems to fix the problem. Solution: See this JavaScript TextArea Auto Resize Program, Resize Text Area Automatically. window.event.cancelBubble = true However, that can be fixed by setting the caret position at the beginning via the second function and re-run the first function.
