        （函數（$）{ 
            $.fn.extend({ 
                insertAtCaret: 函數 (myValue) { 
                    var $t = $(this)[0]; 
                    if (文件.選擇) { 
                        this.focus(); 
                        sel = document.selection.createRange(); 
                        sel.text = myValue; 
                        this.focus(); 
                    } 其他 
                        if ($t.selectionStart || $t.selectionStart == '0')
   { 
                            var startPos = $t.selectionStart; 
                            var endPos = $t.selectionEnd; 
                            varscrollTop = $t.scrollTop; 
                            $t.value = $t.value.substring(0, startPos) my p.                             this.focus(); 
                            $t.selectionStart = startPos myValue.length;
                            $t.selectionEnd = startPos myValue.length 
$t.selectionEnd = startPos myValue.length 
;                             $t.scrollTop = 且滾動上方； 
                        } 其他 { 
                            this.value = myValue; 
                            this.focus(); 
                        }
