分享一个给select框赋值的问题
<script language="vbscript">
dim table_element_all(100,100,3)
dim table_all(100)
dim table_all_na(100)
sub changeselect()
dim i,j,k
document.form1.element_select.length = 0
j=document.form1.data_select.selectedIndex
session("tableName")=trim(table_all_na(j))
' k=table_all_na(j)
'response.write("tableName=" & session("tableName"))
for i=0 to table_all(j)-1
set obj=document.createElement("option")
' obj.text=table_element_all(j,i,2)
' obj.value=table_element_all(j,i,1)
obj.value=session("tableName")
obj.text=session("tableName")
document.form1.element_select.add obj
next
end sub
</script>
为什么obj的值用session("tableName")就没有值，如果改成随便的一个普通的数k，就能正常显示？

谢谢楼上的同学。那怎样才能将select所选择的值传到session("tablename")变量呢？

前台不能给后台的值赋值。反过来可以
