怎样取得input里面的Value值?
<asp:Repeater ID="m_Repeater" runat="server" OnItemCommand="m_Repeater_ItemCommand">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td align="center">
<input id="m_ip" type="checkbox" value='<%# Eval("ID")%>' /><%# Eval("Name")%>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:Repeater>
即是在一个Repeater里面有多个选择项,而各个选择项的value值不一样,那么在cs文件中我要怎么取得这个value值,并当选取的时候自动获得后面绑定的Name值??(ID和Name是在同一表中的两个字段)
[解决办法]
Request[input 的 name 属性 ]
[解决办法]
document.getelementByID("m_ip").values();
看看
[解决办法]
Request.Form["xxxx"]
Request["m_cbname"]这样取得的是什么呢??怎样转到value上面去??
取得的是一组控件中的提交信息,至于你说的怎么转到value上面去,我不是很明白你的本意
既然你已经 <%# Eval("ID")% > 了,还要转什么?
[解决办法]
首先需要把你的
<input id="m_ip" type="checkbox" value= ' <%# Eval("ID")% > ' / > <%# Eval("Name")% >
改成
<Asp:CheckBox id="m_ip" value= ' <%# Eval("ID")% > ' />
<Asp:Label id="m_desc"><%# Eval("Name")% ></Asp:Label>
然后使用以下代码获取值
foreach(Control c in m_Repeater.Items){
CheckBox cb = (CheckBox)c.FindControl("m_ip");
if(true == cb.Checked){
Label l = (Label)c.FindControl("m_desc");
string name = l.Text;
string id = cb.Attributes["value"].toString();
}
}
