问题描述
hi
i有一个下拉列表,其中我有一些名为男性和女性的物品。
我还有另一个文本框标记怀孕计数。
一旦我选择了女性那个怀孕计数应该启用。如果男性它应该禁用c#。
帮助我。
感谢提前。:)
这是我的源代码
< div id = R3C2 style = width:23%; height:7%; float:left; border:Solid 1px Black >
< asp:标签 ID = Gendr runat = server 文本 = 性别 >
< asp:DropDownList ID = DropDwnList1 runat = server
onselectedindexchanged = DropDwnList1_SelectedIndexChanged AutoPostBack = true >
< asp:ListItem > 男性
< asp:ListItem 已选择 = True > 女性
< / div >
< div id = R3C3 style = width:26%; height:7%; float:left; border:Solid 1px Black >
< asp:标签 ID = PrgncyCunt runat = 服务器 文字 = PregnancyCount >
< asp:TextBox ID = TextBox5 runat = server < span class =code-attribute> 宽度 = 15.8% >
< / div >
解决方案
您也可以使用jquery执行此操作:
< script src = http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js > < / script >
< script type = text / javascript >
( document )。ready( function (){
(' #gender')。change( function (){
var value =
