(function ($) {$.fn.extend({insertAtCaret : function (myValue) {var $t = $(this)[0];if (document.selection) {this.focus();sel = document.selection.createRange();sel.text = myValue;this.focus();} elseif ($t.selectionStart || $t.selectionStart == '0') {var startPos = $t.selectionStart;var endPos = $t.selectionEnd;var scrollTop = $t.scrollTop;$t.value = $t.value.substring(0, startPos) + myValue + $t.value.substring(endPos, $t.value.length);this.focus();$t.selectionStart = startPos + myValue.length;$t.selectionEnd = startPos + myValue.length;$t.scrollTop = scrollTop;} else {this.value += myValue;this.focus();}}})})(jQuery);

//调用方法：
$("select").insertAtCaret();
