Question

我有提交按钮的表单，当点击按钮时，它转到下一页并从后端获取所有数据。但根据新的要求，页面需要保持相同的页面，但后端流程应该相同。所以我用Ajax调用按钮来获取后端数据。但它没有按预期工作。请检查以下代码。

<s:form action="product!list" id="searchForm" method="Post" onSubmit="FormSubmitHandler()">
<s:submit action="product" method="list" value="search" />  
</s:form>

我试图运行该页面。

<s:form action="product!list" id="searchForm" method="Post" onSubmit="FormSubmitHandler()">
    <s:submit id="search" />
    </s:form>

jQuery代码：

$("#search").click(function(){
    jQuery.ajax({
     url : '<s:url action="product" method="list" />',
    success : function(data){alert(data)}

    });
    return false;
    });

控制台错误：

行动类：

@Results({@Result(name=pricing.action.PartAction.INPUT,type=ServletDispatcherResult.class,value="/product-search.jsp", params={"location", "/product-search.jsp"}),
@Result(name="success",type=JSONResult.class,value="",params={"root","findList"})

})

@Validation()
public class PartAction extends BaseAction implements Preparable, ServletResponseAware {

public String list(){
    try {
    buildHeaders();

} catch (Exception e) {
    log.error(e);
    super.addActionMessage("No prices were found that match your search criteria.  Please select different options and try again.");
    return SEARCH;
  }
  return LIST;
  }

BaseAction已实施：

@ParentPackage(value="pricing")
public abstract class BaseAction extends ActionSupport implements ServletRequestAware, SessionAware {
 protected static final String LIST = "list"; 
public String execute() throws Exception {

    return SUCCESS;
  }

上面的代码没有在动作类中调用list方法.....请指教。

试试这个脚本

<script type="text/JavaScript">
  $("#searchForm").submit(function(event) {
    event.preventDefault();
    var $form = $(this);
    var url = $form.attr('action');
    $.post(url).done(function(data) {
      alert(data);
    });
  });
</script>

并更改

之类的表单

<s:url var="formUrl" action="product" method="list" />
<s:form action="%{#formUrl}" id="searchForm" method="POST">
  <s:submit/>
</s:form>

修改

它可能不是其他代码的错误，上面的代码没有使用它。在提交按钮后的上述代码中，调用product动作。然后你应该在课堂上添加@Action(name="product")

@Action(name="product") @Results({ @Result(name=INPUT,type=ServletDispatcherResult.class, value="/product-search.jsp"), @Result(name=SUCCESS,type=JSONResult.class,value="",params={"root","findList"}) }) @Validation() public class PartAction extends BaseAction { //removed interfaces that aren't implemented private List<Object> findList = new List<Object>(); //you could use any type instead of Object public List<Object> getFindList(){ //this is needed to JSON result return findList; } public String list(){ try { buildHeaders(); } catch (Exception e) { log.error(e); addActionMessage("No prices were found that match your search criteria. Please select different options and try again."); //super is not needed use protected modifire return INPUT; //the result should be above } return SUCCESS; //the result should be above } }
