struts2中得到checkbox的值:

struts2中得到checkbox的值:

action中得到的是一个字符串,用","隔开。所以在action中定义一个属性值接收checkbox的name，然后拆串即可。

html：

Html代码  

1. <input type="checkbox" name="check" value="111">
2. <input type="checkbox" name="check" value="222">
3. <input type="checkbox" name="check" value="333">

 action：

Java代码  

1. private
2. //getter and setter..
3. String ids = this.getCheck();  
4. System.out.println("ids::"+ids);  
5. String[] arraycheck = ids.split(", ");

 这样action就得到了checkbox的value值。

注意：action为我们取到得数组格式为[val1,  val2,   val3]的形式，逗号后边带个空格，所以用split拆分字符串的时候参数要传入", "而不是","，否则在遍历该数组的时候，只有val1的值取出是正确的。
