checked radio button from JSP scriptlet variable
提问by AzAh
This is going to be a stupid question but i need to ask it.
PS: this is an old practice but i need it this way.
In scriptlet I have a variable status.
这将是一个愚蠢的问题，但我需要问它。PS：这是一种古老的做法，但我需要这种方式。在 scriptlet 中，我有一个变量status。
<%
String status=bean.getStatus();
//Status value is coming from database which is either "1" or "0"(String type)
%>
In a form I have radio button.
在表单中，我有单选按钮。
<tr>
<td> Status :</td>
<td>Active
<input type="radio" name="status" checked="checked" id="statusAct" value="1" />
Inactive
<input type="radio" name="status" id="statusInac" value="0"/>
</tr>
If status==1I want radio button with id="statusAct"to be selected and if status==0then radio with id="statusInac"to be selected.
如果status==1我想要选择单选按钮，然后id="statusAct"选择单选按钮。status==0id="statusInac"
I can use javascript or Jquery but I don't know how to put Java variable inside javascript function.
我可以使用 javascript 或 Jquery，但我不知道如何将 Java 变量放入 javascript 函数中。

你可以简单地做
<input type="radio" name="status" <% ${bean.getStatus() == '1' ? 'checked="checked"' : '' } %> id="statusAct" value="1" />
and
和
<input type="radio" name="status" <% ${bean.getStatus() == '0' ? 'checked="checked"' : '' } %> id="statusInac" value="1" />

Either use scriptlets to do conditional logic and write checked ="checked" where you need to. In the scriptlets you can do out. println to write to the page (output stream). You could also use jstl for condition tags c:if
要么使用 scriptlet 来做条件逻辑，并在需要的地方写 checked ="checked" 。在scriptlets中你可以做到。println 写入页面（输出流）。您还可以将 jstl 用于条件标签 c:if
