using thymeleaf之七设置属性的值(th:attr/th:value/th:alt-title/th:attrappend/th:attrprepend/th:checked)

7.1 th:attr

用于设置其他属性的值,但不是所有属性的值都能设置,如text。

 

<form action="subscribe.html" th:attr="action=@{/subscribe}">  
  <fieldset>  
    <input type="text" name="email" />  
    <input type="submit" value="Subscribe me!" th:attr="value=#{subscribe.submit}"/>  
  </fieldset>  
</form>  

  

th:attr还可以同时设置多个属性的值,以逗号隔开

 

<img src="../../images/gtvglogo.png"   
     th:attr="src=@{/images/gtvglogo.png},title=#{logo},alt=#{logo}" />  


7.2 th:alt-title

用于设置 alt 和title属性的值相同的两个属性。

<img src="../../images/gtvglogo.png"   
     th:src="@{/images/gtvglogo.png}" th:title="#{logo}" th:alt="#{logo}" />  

 

 

用th:alt-title后:

<img src="../../images/gtvglogo.png"   
     th:src="@{/images/gtvglogo.png}" th:alt-title="#{logo}" />  


7.3 th:attrappend和th:attrprepend

th:attrappend属性值前缀,例如一个标签的类名为a,想要变为“a b”,即增加一个类样式,可以使用此属性.

 

<input type="button" value="Do it!" class="btn" th:attrappend="class=${‘ ‘ + cssStyle}" />  


th:attrprepend的用法则相反,

th:attrappend="class=${cssStyle+‘ ‘}"  

 

7.4 th:checked设置复选框的值

此为布尔值属性之一,以后会详细介绍其他属性,在此先介绍th:checked。

(1)选中为:

<input type="checkbox" name="active" th:checked="true" /> 

 

(2)未选中为:

 

<input type="checkbox" name="noactive" th:checked="false" />  

 

thymeleaf解析时不会设置th:checked属性,即解析后为

<input type="checkbox" name="noactive" />
