JS获取一行2列的表格数据

JS如下：

如何在JS中获取下拉框中的value和Text值呢？

获取Text值：

document.getElementById(s[0]).options[window.document.getElementById(s[0]).selectedIndex].Text;

获取value值：

document.getElementById(s[0]).options[window.document.getElementById(s[0]).selectedIndex].value

s[i] 数组中保护3个数据项：主键ID，控件ID，控件类型。

function createTasks() {
if (Page_ClientValidate()) {
var rows = document.getElementById('EidtTable').rows;
var result = '';
var str = "<%=str%>"
var arry = str.split(";");
for (var i = 0; i < arry.length; i++) {
var s = arry[i].split(",");
switch (s[1]) {
case "TextBox":
var rowString = s[2]+"_"+document.getElementById(s[0]).value + ',';
break
case "radiobuttonlist":
var list = document.getElementById(s[0]).getElementsByTagName("input");
var strData = "";
for (var j = 0; j < list.length; j++) {
if (list[j].type == "radio") {
if (list[j].checked) {
var rowString = s[2] + "_" + list[j].value + ',';
}
}
}
break;
case "TexBoxM":
var rowString = s[2] + "_" + document.getElementById(s[0]).value + ',';
break
case "DateTime":
var rowString = s[2] + "_" + document.getElementById(s[0]).value + ',';
break
case "FileUpload":
var rowString = s[2] + "_" + document.getElementById(s[0]).value + ',';
break
case "DropDownList":
var rowString = s[2] + "_" + document.getElementById(s[0]).options[window.document.getElementById(s[0]).selectedIndex].value + ',';
break
case "Hdf":
var hdf1 = document.getElementById(("hdf" + s[0] + "0")).value;
var hdf2 = document.getElementById(("hdf" + s[0] + "1")).value;
var rowString = s[2] + "_" + hdf1 + "-" + hdf2 + ',';
break
default:
break;

}
result = result + rowString;

}
document.getElementById("hdfValues").value = result;

}

}
