將字符串轉換為二維數組

                            var arr1=Mtxts.split(";");

                            var arr2 = new Array(arr1.length);

                            for (var i = 0; i < arr1.length-1; i++)

                       {

                         //定義臨時數組

                         var temp =new Array(2);

                         //將一維數組再次拆分，准備存入二維數組

                         temp = arr1[i].split("*");

                         //定義將要存放數據的一維數組的每一個元素都為一個數組(實際上就是定義二維數組了)

                         arr2[i] = new Array(temp.length);

                         //遍歷臨時數組將其值存入二維數組

                         for (var j = 0; j < temp.length; j++)

                         {

                           arr2[i][j] = temp[j];//完成字符串轉換為二維數組

                         }
