Getting the value from asp:LinkButton's CommandArgument attribute using jquery/javascript
提问by LobalOrning
I need to get the value of the CommandArgumentattribute of a LinkButton, in an asp:Repeater.
我需要CommandArgument在 asp:Repeater 中获取LinkButton的属性值。
I have an asp:Repeater with 2 LinkButtons whose CommandArgument I set to a value:
我有一个带有 2 个 LinkButtons 的 asp:Repeater，我将其 CommandArgument 设置为一个值：
<ItemTemplate>
<tr class="odd">
<td><%#DataBinder.Eval(Container.DataItem, "batch_id")%></td>
<td><%#DataBinder.Eval(Container.DataItem, "productId")%></td>
<td><%#DataBinder.Eval(Container.DataItem, "serial_number")%></td>
<td><%#DataBinder.Eval(Container.DataItem, "activation_card_number")%></td>
<td><%#DataBinder.Eval(Container.DataItem, "transaction_amount","{0:C}")%></td>
<td><%#DataBinder.Eval(Container.DataItem, "response_dt", "{0:M/d/yyyy HH:mm:ss}")%></td>
<td style="text-align:center;"><%#DataBinder.Eval(Container.DataItem, "resp_process_msg")%></td>
<td style="text-align:center;"><%#DataBinder.Eval(Container.DataItem, "resp_response_code")%></td>
<td style="text-align:center;"><asp:LinkButton ID="lnkBtnRestageAdd" CommandName="Add" CommandArgument='<%#Eval("activation_card_number")%>' runat="server" Text="stage" class="add" OnClientClick="return false;" /></td>
<td style="text-align:center;"><asp:LinkButton ID="lnkBtnRestageMinus" CommandName="Subtract" CommandArgument='<%#Eval("activation_card_number")%>' runat="server" Text="stage" class="minus" OnClientClick="return false;" /></td>
</tr>
</ItemTemplate>
I have suppressed the PostBack with OnClientClick="return false;" so that I can pop a jQuery dialog modal when the link buttons get clicked:
我用 OnClientClick="return false;" 抑制了 PostBack 这样我就可以在点击链接按钮时弹出一个 jQuery 对话框模式：
if (btnAdd != null) {
$(".add").click(function() {
$("#<%=divDialogAdd.ClientID %>").removeAttr("style");
$("#<%=divDialogAdd.ClientID %>").dialog("open");
});
}
In the modal I have 2 other asp:LinkButtons, and when the 'Yes' button is clicked I do the postback like so:
在模态中，我还有另外两个 asp:LinkButtons，当单击“是”按钮时，我会像这样执行回发：
yesBtn.click(function() {
setTimeout('__doPostBack(\'btnAdd\',\'\')', 0); //need to add a param
});
What I need to do, is somehow grab the CommandArgument value from the LinkButton in the Repeater, so that I can pass that as a parametere or assign it to a hidden field. I have tried jQuery's attr(), but that only works when the attribute was set using that function as well. How can I get this value, or what other way can I go about this?
我需要做的是以某种方式从中继器中的 LinkButton 获取 CommandArgument 值，以便我可以将其作为参数传递或将其分配给隐藏字段。我尝试过 jQuery 的attr()，但只有在使用该函数设置属性时才有效。我怎样才能得到这个值，或者我可以用什么其他方式来解决这个问题？

I don't think you can get that property in javascript. Because the command argument is passed as the the argument in the doPostBack function. But i think you can change your code like this to decrease the complexity.
我认为您无法在 javascript 中获得该属性。因为 command 参数是作为 doPostBack 函数中的参数传递的。但我认为您可以像这样更改代码以降低复杂性。
<asp:LinkButton ID="lnkBtnRestageAdd"
CommandName="Add"
CommandArgument='<%#Eval("activation_card_number")%>'
runat="server"
Text="stage"
class="add"
OnClientClick='<%#Eval("activation_card_number","javascript:return YourFunction({0});")%>' />
do the stuff that you want to do in the function YourFunctionreturn trueif Yes is pressed and return false
如果按下 Yes 并返回，则在函数YourFunctionreturn 中执行您想要执行的操作truefalse
