C＃/ ASP.NET / JS-onclick事件显示行，回发隐藏行

Question

rbnResubmission.Items.FindByValue("Yes").Attributes.Add("onclick", "getCheckedRadioFieldResubmission(this)");
rbnResubmission.Items.FindByValue("No").Attributes.Add("onclick", "getCheckedRadioFieldResubmission(this)");

So I have these click events for showing rows in a table - that part works fine. 所以我有这些单击事件，用于在表中显示行-该部分工作正常。

Here's an example of what the code does (I'm not showing the "No" option) 这是代码功能的示例（我没有显示“否”选项）

function getCheckedRadioFieldResubmission(radio){
    if(radio.value == "Yes"){
         document.getElementById('<%=ApprovingInstituteRow.ClientID%>').style.display ="block";
         document.getElementById('<%=ApprovalNumberRow.ClientID%>').style.display ="block";
         document.getElementById('<%=IRBApprovalRow.ClientID%>').style.display ="block";
         document.getElementById('<%=ExpectedDateRow.ClientID%>').style.display ="none";
     }
}

The form needs to go through validation, and if there's any problems, because the event to show these rows only happens from "onclick" - they will disappear upon postback. 表单需要进行验证，如果有任何问题，因为显示这些行的事件仅发生在“ onclick”上-它们将在回发后消失。 what can I change to make them appear permanently? 我该如何更改以使其永久显示？

Answer 1

I'm guessing you're databinding the radio button list during onLoad. 我猜你在onLoad期间绑定了单选按钮列表。 You have to rebind it on postback. 您必须在回发时重新绑定它。

Answer 2

You'll probably want to add the same functionality of your getCheckedRadioFieldResubmission function into the onload event of the html <body> tag. 您可能需要将与getCheckedRadioFieldResubmission函数相同的功能添加到html <body>标记的onload事件中。 However, since the this object will refer to the body element and not the radio, you'll need to put something of this sort in there to find the radio: 但是，由于this对象将引用body元素而不是无线电，因此您需要在其中放置某种东西才能找到无线电：

var radio = document.getElementById('radio_id');

This will work if your radio list has a maintained state. 如果您的单选列表处于维护状态，这将起作用。 As in, it keeps it's state after Post Back. 与之类似，它保持“回发”后的状态。
