Move Cursor To End of Textarea or Input

0
0

Code to move the cursor to the end of the current text within in the input, rather than the default (highlighting the text).

#Plugin format

jQuery.fn.putCursorAtEnd = function() {

  return this.each(function() {
    
    // Cache references
    var $el = $(this),
        el = this;

    // Only focus if input isn't already
    if (!$el.is(":focus")) {
     $el.focus();
    }

    // If this function exists... (IE 9+)
    if (el.setSelectionRange) {

      // Double the length because Opera is inconsistent about whether a carriage return is one character or two.
      var len = $el.val().length * 2;
      
      // Timeout seems to be required for Blink
      setTimeout(function() {
        el.setSelectionRange(len, len);
      }, 1);
    
    } else {
      
      // As a fallback, replace the contents with itself
      // Doesn't work in Chrome, but Chrome supports setSelectionRange
      $el.val($el.val());
      
    }

    // Scroll to the bottom, in case we're in a tall textarea
    // (Necessary for Firefox and Chrome)
    this.scrollTop = 999999;

  });

};

#Usage

var searchInput = $("#search");

searchInput
  .putCursorAtEnd() // should be chainable
  .on("focus", function() { // could be on any event
    searchInput.putCursorAtEnd()
  });
