As shown below:
$.fn.setCursorPosition = function(position) {
if (this.lengh == 0)
return this;
return $(this).setSelection(position, position);
};
$.fn.setSelection = function(selectionStart, selectionEnd) {
if (this.lengh == 0)
return this;
input = this[0];
if (input.createTextRange) {
var range = input.createTextRange();
range.collapse(true);
range.moveEnd('character', selectionEnd);
range.moveStart('character', selectionStart);
range.select();
} else if (input.setSelectionRange) {
input.focus();
input.setSelectionRange(selectionStart, selectionEnd);
}
return this;
};
$.fn.focusEnd = function() {
this.setCursorPosition(this.val().length);
};
