JQuery Set Cursor Position in Text Area

Question

JQuery Set Cursor Position in Text Area

How do you set the cursor position in a text field using jQuery? I've got a text field with content, and I want the users cursor to be positioned at a certain offset when they focus on the field. The code should look kind of like this:

$('#input').focus(function() {

  $(this).setCursorPosition(4);

});

What would the implementation of that setCursorPosition function look like? If you had a text field with the content abcdefg, this call would result in the cursor being positioned as follows: abcd|efg.

Java has a similar function, setCaretPosition. Does a similar method exist for javascript?

Update: I modified CMS's code to work with jQuery as follows:



new function($) {

  $.fn.setCursorPosition = function(pos) {

    if (this.setSelectionRange) {

      this.setSelectionRange(pos, pos);

    } else if (this.createTextRange) {

      var range = this.createTextRange();

      range.collapse(true);

      if(pos < 0) {

        pos = $(this).val().length + pos;

      }

      range.moveEnd('character', pos);

      range.moveStart('character', pos);

      range.select();

    }

  }

}(jQuery);

I have two functions:



function setSelectionRange(input, selectionStart, selectionEnd) {

  if (input.setSelectionRange) {

    input.focus();

    input.setSelectionRange(selectionStart, selectionEnd);

  }

  else if (input.createTextRange) {

    var range = input.createTextRange();

    range.collapse(true);

    range.moveEnd('character', selectionEnd);

    range.moveStart('character', selectionStart);

    range.select();

  }

}



function setCaretToPos (input, pos) {

  setSelectionRange(input, pos, pos);

}

Then you can use setCaretToPos like this:



setCaretToPos(document.getElementById("YOURINPUT"), 4);

Here's a jQuery solution:



$.fn.selectRange = function(start, end) {

    if(end === undefined) {

        end = start;

    }

    return this.each(function() {

        if('selectionStart' in this) {

            this.selectionStart = start;

            this.selectionEnd = end;

        } else if(this.setSelectionRange) {

            this.setSelectionRange(start, end);

        } else if(this.createTextRange) {

            var range = this.createTextRange();

            range.collapse(true);

            range.moveEnd('character', end);

            range.moveStart('character', start);

            range.select();

        }

    });

};

With this, you can do



$('#elem').selectRange(3,5); // select a range of text

$('#elem').selectRange(3); // set cursor position
