Question

如何在客户端对Web DropDownList控件付值（多值）？或者将数组中的值付给DropDownList控件？谢谢！！

Answer 1

o = document.getElementById("DropDownList1")
var a = new Array("1","2")
for(i = 0;i<a.length;i++)
o.options[o.options.length] = new Option(a[i],a[i])

Answer 2

下面的代码必须放在DropDownList1生成以后：var obj = document.getElementById("DropDownList1");var customOptions = document.createElement("OPTION");  
customOptions.text = "key1";
customOptions.value = "value1";obj.add(customOptions);customOptions = document.createElement("OPTION");  
customOptions.text = "key2";
customOptions.value = "value2";obj.add(customOptions);
