在textfield中的Struts2 / css [英] Struts2 / css in textfield

问题描述

我从struts2编程开始，我想知道如何做下面的事情。我有这样的struts代码：

 < s：textfield name =aName/> 
  

在使用struts2之前，我有了这个html代码：

 < input id =aLogintype =textclass =form-controlname =usernamevalue =placeholder =somethingrequired autofocus> 
  

我怎样才能合并这两行来执行相同的html代码，但使用我的struts2代码？

解决方案在Struts标签中， class ans style 变成 cssClass 和 cssStyle ;在旧版本的Struts中， required 是一个属性，指示何时将 * 标记更改为 requiredLabel 以避免重写HTML5必需的属性。可以设置其他HTML5属性，如 placeholder 和 autofocus ，因为Textfield标记允许动态属性。

然后在您的案例中：

 < s：textfield id =aLogin
 name =aName
 cssClass =form-control
 value =
 placeholder =something
 required 
自动对焦/>

I am beginning with struts2 programming and I wondered how I could do the following thing. I have this struts code in a form :

<s:textfield name="aName"/>

And I had this html code before using struts2 :

<input id="aLogin" type="text" class="form-control" name="username" value="" placeholder="something" required autofocus>

How could I "merge" these two lines to do the same html code but using my struts2 code ?

解决方案

In Struts tags, class ans style becomes cssClass and cssStyle; in old versions of Struts, required was an attribute indicating when to put the * mark, now changed to requiredLabel to avoid overriding the HTML5 required attribute. Other HTML5 attributes like placeholder and autofocus can be set because Textfield tag Allows Dynamic Attributes.

Then in your case:

<s:textfield id = "aLogin" 
           name = "aName" 
       cssClass = "form-control" 
          value = ""
    placeholder = "something" 
       required
      autofocus />
