JS move focus to the last position of the simple method _javascript tips

When the input box (Input/textarea) Gets the focus, the focus is moved to the end, and in some cases the user experience is good. Most of the methods on the web are for IE browsers.

The code is as follows:

var el = document.getElementById (' txtarticle ');
var range = El.createtextrange ();
Range.movestart (' character ', el.value.length);
Range.collapse (false);
Range.Select ();

You can actually delete the MoveStart line because the createTextRange method creates a range and uses the Collapse method, and the argument is false to move to the end. Collapse (true) moves the cursor to the beginning of the range, collapse (false) moves the cursor to the end of the range. Standard browsers such as Firefox can use the Setselectionrange method of the consortium.

The code is as follows:

var range, el = document.getElementById (' Txtphone ');
if (el.setselectionrange) {
  el.focus ();
  El.setselectionrange (El.value.length, el.value.length)
} else {
  range = El.createtextrange ();
  Range.collapse (false);
  Range.Select ();
}

Note that the Setselectionrange method applies only to Input/textarea elements. The focus of other non native editable elements is moved to the collapse method that can take advantage of the Selection object.

For example:

var sel, el = document.getElementById (' hint ');
sel = Window.getselection ();
Sel.collapse (el, 1);
El.focus ();

The above JS move focus to the final position of the simple method is small to share all the content of everyone, hope to give you a reference, but also hope that we support the cloud habitat community.
