Js 实现将table的行列的值填充到TEXTBOX

效果图如下：

        function CheckAll(checkAllBox) {
                var values="";
                var tab = document.getElementById('tb');
                var checklist = document.getElementsByName('checklist');
                for (var i = 0; i < checklist.length; i++) {
                    if (checklist[i].type == "checkbox") {
                        if (checklist[i].checked) {
                            var temp = tab.rows[i].cells[2].innerHTML;
                            values = values +"_"+ temp;
                        }
                    }
                }
                document.getElementById('TextBox1').value = values.substring(1, values.length);
            }
