To be honest I don't really understand the question after those code blocks, but I can say that you can use inline condition in your views in ASP.NET MVC3. 坦白地说,在这些代码块之后,我并没有真正理解这个问题,但是我可以说,您可以在ASP.NET MVC3的视图中使用内联条件。 Something like that for example:
例如:
bool isChecked = false;
<input type="checkbox" name="x" @(isChecked ? "checked=checked" : "") />
It's shorter and it will produce code like that: 它更短,并且会生成如下代码:
<input type="checkbox" name="x">
And BTW, there is a helper method Html.CheckBox
to create checkbox in your view and in second parameter you can indicate if you want it to be checked: 顺便说一句,有一个辅助方法
Html.CheckBox
可以在视图中创建复选框,在第二个参数中,您可以指示是否要对其进行检查:
@{bool isChecked = false;}
@Html.CheckBox("x", isChecked)
And that will rendrer this: 这将使此问题:
<input id="x" type="checkbox" value="true" name="x">
<input type="hidden" value="false" name="x">
Try it on your own. 自己尝试。
