HTML5 placeholder inside Struts html:text tag

问题

I'm using Struts 1.3.10 in a web application, and I want my textfields to have a placeholder. Unfortunately, the current Struts taglib doesn't recognize this attribute, and I would like to avoid using javascript for this if possible. Do you know any solution for this?

回答1:

Struts 1 is dead. It hasn't had a release since 2008. I would really think about migrating to a more modern framework.

If you're stuck with Struts 1, you could

• edit the sources yourself, and add a placeholder attribute to the tag.

• avoid using the tag, and go back to basic HTML + JSTL + EL :

  <input type="text" name="foo" value="<c:out value='${myForm.foo}' />" 
         placeholder="Enter foo here" />

In case this might be helpful to others:

If you have a JavaBean (with getters and setters) you could use basic html and the bean:write struts tag.

<input type="text" name="foo" placeholder="Enter foo here"value="<bean:write name="myFormBean" property="foo" />">
