Scala模板将样式应用于inputText的标签[播放2 HTML5 helper标签] [英] Scala Template apply style to inputText's label [Play 2 HTML5 helper tag]

问题描述

我正在将scala模板与输入助手一起使用.

I am using scala template with input helper.

我使用的class属性将样式应用于<input>标记.

The class attribute which i use applies style for the <input> tag.

如何将特定的样式应用于生成的<label>标签?

How do i apply the style specific to the generated <label> tag?

@inputText(orderItem("item1"),'_label -> "Product*",'_class -> "tinytfss")

预先感谢您的支持.马诺伊

推荐答案

您可以尝试放弃内置字段构造函数，而改为编写自己的.以下模板接受用于控制标签样式的自定义参数:

You could try ditching the built-in field constructors and instead write your own. The following template accepts a custom argument that controls the styling of the label:

app/views/_my_field_constructor.scala.html

@(element: helper.FieldElements)

<div class="clearfix @if(element.hasErrors){error}">
  <label for="@element.id" class="@element.args.get('_label_class)">@element.label</label>
  <div class="input">
    @element.input
  </div>
</div>

现在使用新的字段构造函数，而不要使用之前使用的任何内置构造函数:

Now use your new field constructor instead of whichever built-in one you were using before:

app/views/form.scala.html

....
@* implicitFieldConstructor = @{ FieldConstructor(twitterBootstrapInput.f) } *@
@implicitField = @{ FieldConstructor(_my_field_constructor.f) }
....

在调用helper函数创建输入文本字段时，您现在可以传递一个自定义的_label_class参数，模板将使用该参数:

When calling the helper function to create a input text field, you can now pass in a custom _label_class argument that the template will pick up:

app/views/form.scala.html

@inputText(orderItem("item1"), '_label -> "Product", '_label_class -> "red", '_class -> "tinytfss")
