Use JavaScript to place cursor at end of text in text input element

Question

What is the best way (and I presume simplest way) to place the cursor at the end of the text in a input text element via JavaScript - after focus has been set to the element

Answer 1

I also faced same problem. Finally this gonna work for me:

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;

  });

};

This is how we can call this:

var searchInput = $("#searchInputOrTextarea");

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

It's works for me in safari, IE, Chrome, Mozilla. On mobile devices I didn't tried this.
