Struts2 checkbox applicable scenarios and analysis is like this, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

First of all, it is necessary to find out the situations in which Struts2 checkbox is applicable, such as yes, no, yes, no, match, non-fit, male, female and so on.

Wrote a test interface.

< ?xml:namespace prefix = s />

< s:checkbox name="checkbox" value="checkbox1">

< /s:checkbox>

< s:checkbox name="checkbox" value="checkbox2">

< /s:checkbox>

< s:checkbox name="checkbox" value="checkbox3">

< /s:checkbox>

Define one in action:

Private String [] checkbox;public void setCheckbox (String [] checkbox) {this.checkbox = checkbox;}

It looks like it can, but actually. It is not possible to do so. Two element are generated for checkbox in the generated html.

One is Struts2 checkbox's value will always be true/false.

In addition, a hidden.

Without saying much, View Source can see it.

Since this doesn't work, then I try to use html directly.

< INPUT value=checkbox1 type=checkbox name=checkbox>

< INPUT value=checkbox2 type=checkbox name=checkbox>

< INPUT value=checkbox3 type=checkbox name=checkbox>

Action does not change, hey ~!. That's the right result!

Therefore, if there is really no way, or try the most primitive method, there is no harm.
