Question

我正在使用來自Jquery ajax的Spring MVC調用。該呼叫擊中控制器，並將結果顯示在切換側。但是，在我的瀏覽器的代碼所示沒有什麼

$.ajax({ 
     url: "http://localhost:8080/sample/sample-byName", 
     cache: false,    
     data:'firstName=' + $("#firstName").val() + "&lastName=" + $("#lastName").val() + "&currentCompany=" + $("#currentCompany").val(), 
     dataType:"text", 
     crossDomain : true, 
     ContentType:"text/html", 
     success: function(data){ 
      alert(data); 
     }, 
     error: function(e){      
      alert('Error while request..'+e); 
     } 
    }); 

當我通過螢火看到它說200 OK。任何人都可以幫我嗎？

我控制器代碼是通過Ajax

public @ResponseBody String getLinkedInByName(HttpServletRequest request) { 

     String firstName = request.getParameter("firstName"); 
     String lastName = request.getParameter("lastName"); 
     String currentCompany = request.getParameter("currentCompany"); 


     String resultJson = client.getNameSearchWithHelpers(firstName,lastName,currentCompany); 
     System.out.println(resultJson); 
     return resultJson; 
    } 

淨結果Allow GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH Content-Length 0 Date Tue, 16 Jul 2013 05:17:18 GMT Server Apache-Coyote/1.1

普通URL提交 Content-Length 640 Content-Type text/html Date Tue, 16 Jul 2013 05:14:21 GMT Server Apache-Coyote/1.1

使用此代碼

你犯的錯誤傳遞值

個

值應該傳遞這樣

data: { name: "value", location: "value" } 

JS

$.ajax({ 
    url: "http://localhost:8080/sample/sample-byName", 
    cache: false,    
    data:{firstName:$("#firstName").val() 
     ,lastName:$("#lastName").val(), 
     currentCompany:$("#currentCompany").val() 
    }, 
    dataType:"text", 
    crossDomain : true, 
    ContentType:"text/html", 
    success: function(data){ 
    alert(data); 
    }, 
    error: function(e){      
    alert('Error while request..'+e); 
    } 
});
