              <h1>Put Cursor at End of Input</h1>

<input type="search" value="Potato Pancakes" id="search">

            
          
!

CSS

            
              body {
  padding: 10px;
}
            
          
!

JS

            
              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;

  });

};

(function() {
  
  var searchInput = $("#search");

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