I have form in Jade file, and I want it to be pre-filled with some values that come from backend.In the form, there are radio buttons for user gender.

input(type="radio", name="gender_filter", value="1") Male
input(type="radio", name="gender_filter", value="0") Female

Now I also have this variable gender_param, and I want the corresponding button to be selected when page loads. In PHP, I could do this:

<input type="radio" name="gender_filter", value="1" <?php echo ($gender_param==1)?"checked":''; ?>>

Is there the corresponding syntax for Jade? Or I need to write it in the long way with line duplicates like

- if gender_param==1
   input(type="radio", name="gender_filter", value="1", checked) Male
- else
   input(type="radio", name="gender_filter", value="1") Male

你可以在jade中做到这一点，甚至比在PHP中更简单：

input(type="radio", name="gender_filter", value="1", checked=gender=="male")
| Male
input(type="radio", name="gender_filter", value="0", checked=gender=="female")
| Female

此代码块期望gender是从后端传递到视图的变量。

对于 Jade：这里有一些输入类型和在提交表单后保持选中值的简写，即这样您就可以填充编辑页面...

单选按钮：

input(type="radio" name="stars" value='1' id='stars' checked=theAlbum.rating=='1')

选择框：

option(selected = theAlbum.genre) #{theAlbum.genre}

option Jazz option Rock option Rap option Dance

复选框：

checked=theAlbum.checkbox
