html table 粘贴 excel

   $('table').bind('paste', function (e) {

                //消除默认粘贴

                if (document.all)   //判断IE浏览器

                    window.event.returnValue = false;

                else event.preventDefault();

                //获取粘贴板数据

                var data = null;

                var clipboardData = window.clipboardData || e.originalEvent.clipboardData; // IE || chrome  

                data = clipboardData.getData('Text');

                console.log(data.replace(/\t/g, '\\t').replace(/\n/g, '\\n')); //data转码

                //解析数据

                var arr = data.split('\n')

        .filter(function (item) {    //兼容Excel行末\n，防止出现多余空行

            return (item !== "")

        }).map(function (item) {

            return item.split("\t");

        });

                //输出至网页表格

                var tab = this;  //表格DOM

                var td = $(e.target).parents('td');

                var startRow = td.parents('tr')[0].rowIndex;

                var startCell = td[0].cellIndex;

                var rows = tab.rows.length;  //总行数

                for (var i = 0; i < arr.length && startRow + i < rows; i++) {

                    var cells = tab.rows[startRow + i].cells.length;  //该行总列数

                    for (var j = 0; j < arr[i].length && startCell + j < cells; j++) {

                        var cell = tab.rows[startRow + i].cells[startCell + j];

                        $(cell).find(':text').val(arr[i][j]);  //找到cell下的input:text，设置value

                    }

                }

            });
