struts2确认动作框

Question

I am trying to call struts2 action when I click 'OK' in confirm box. I have an id from jsp and I want to pass it into the action. I've tried several ways with no success.

One thing is using href:

 <s:url action="disable" var="urlTag">
     <s:param name="id"><s:property value="id"/></s:param>
 </s:url>

window.location.href="{urlTag}";

I also tried using ajax

        $.ajax( {  
            type: "POST",        
            url: "%{urlTag}",  //will this declaration of action work?   
            dataType: "json",  
            contentType: "application/json; charset=utf-8",  
            data: "",  
            success: function() {  
                alert("success");    
            }  
       });  

I am new to this and really want to get though it. Thank you for any help!

Answer 1

You can achieve it as following.

 <s:url id="yourActionId" action="yourAction">
    <s:param name="param1" value="param1Value"/>
    <s:param name="param2" value="param2Value"/>
 </s:url> 
 <s:a href="%{yourActionId}" onclick = "return confirmBox();"><b>Save</b></s:a>

& your javascript function should be as follows.

function confirmBox() {
   var answer;
   answer = window.confirm("Do you really want to perform this action");
   if (answer == true) {
      return true;
   } else {
      return false;
   }
}

What we have done here is, In s:url tag we have given action to perform with the parameters & given an id to it. That id is passed to the s:a tag & on click of s:a link we are calling a java script function which will open a confirm box & return true if you press OK & action will be called. If you press cancel it will return false & action will not be called. Hope this will help you.

To make your code work with Struts tags:

window.location.href = "<s:property value='%{#urlTag}' />";

and

$.ajax( {  
       type: "POST",        
        url: "<s:property value='%{#urlTag}' />",  

That said, I'm not saying this is what you need. Are you sure about what you need to do ? GET ? POST ? An AJAX call, what ?
