下面小編就為大家?guī)硪黄狫ava中前臺往后臺傳遞多個id參數(shù)的實例。小編覺得挺不錯的，現(xiàn)在就分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

1.傳字符串的形式，字符串中每個id用 “，” 隔開

打印出來如下形式：

前臺JS代碼

function saveRoleAdd()
 {
  
  var roleNames = $('#roleNames').textbox("getText");
  var roleDetail = {};
   roleDetail.roleNames = roleNames;
  roleDetail.roleFunctionCount = 0;
  roleDetail.roleFunctionList = [];
  
  if(roleNames.length < 0 || roleNames.length == 0)
  {
   $.messager.alert("提示","請輸入角色名");
   return;
  }
  
  
  var funNodeList = $('#roleFuntionTree').tree('getChecked', 'indeterminate');
  var funLeafList = $('#roleFuntionTree').tree('getChecked');
  
  if(funNodeList.length <=0 && funLeafList.length <= 0)
  {
   $.messager.alert("提示","請選擇權(quán)限節(jié)點");
   return;
  }
  
 
  Array.prototype.push.apply(funNodeList, funLeafList); //將兩個lis合并為一個數(shù)組
  
  var roleFunList = "";
  var roleFunNameList = "";
  for(var i=0; i < funNodeList.length; i++)
  {
   if (!isEmptyTarget(funNodeList[i].id))
   {
    if(!isEmptyTarget(roleFunList))
    {
    roleFunList += ",";  //拼接成用逗號隔開的字符串,里面是id
    roleFunNameList += ","; //拼接成用逗號隔開的字符串，里面text
    }
    roleFunList += funNodeList[i].id;
    roleFunNameList += funNodeList[i].text;
    
    var funDetail = {};
    funDetail.funId = parseInt(funNodeList[i].id);
    roleDetail.roleFunctionList.push(funDetail);  
   }
  }
  roleDetail.roleFunctionCount = roleDetail.roleFunctionList.length; 
  
  var rows = $("#tblRoleDetail").datagrid("getRows");
  for (var i = 0; i < rows.length; i++)
  {
   if (roleNames == rows[i].roleNames)
   {
    $.messager.alert("提示","重復(fù)的角色名!");
    return;
   }
  }
  
  $('#tblRoleDetail').datagrid('appendRow',
   {
    roleNames:roleNames,
    funId:roleFunNameList
    }
  );
  
   
   $.ajax(
   {
    type : "POST",
    url : "permiss-manager/setRoleDetail.action?_dc=" + Math.random(),
    data :
   {
    roleName:roleNames,
    roleDetailData : roleFunList,
   },
    dataType : "json",
   success : function(result)
   {
    $.messager.alert("提示",result.result);
    closeRoleAdd();
    refreshRoleSelectTree();
   } 
  });
    
   $('#rolePanel').panel('refresh', "afc/page/permission-manager/role-main.jsp");  
 }

后臺Action方法代碼

@Action("setRoleDetail")
 public void setRoleDetail()
 {
  webLogService.writeWebLog(ServletActionContext.getRequest().getSession().getAttribute("userId").toString(), "新增角色", ServletActionContext.getRequest().getRemoteAddr());

  String roleName = ServletActionContext.getRequest().getParameter("roleName");
  String roleDetailJsonData = ServletActionContext.getRequest().getParameter("roleDetailData");
  // 這一部分就是轉(zhuǎn)成一個list。下面調(diào)用方式直接傳一個list過去 
  List<Integer> funIdList = new ArrayList<Integer>();
  String [] arrar = StringUtils.split(roleDetailJsonData, ",");
  for (int i = 0; i < arrar.length; i++)
  {
   Integer funId = null;
   if(NumberUtils.isNumber(arrar[i]))
   {
    funId = NumberUtils.toInt(arrar[i]);
    funIdList.add(funId);
   }
   
  } 
  permissionService.setRole(roleName, funIdList);
  try
  {
   HttpServletResponse response = ServletActionContext.getResponse();
   response.setCharacterEncoding("utf-8");
   JSONObject result = new JSONObject();
   result.accumulate("result", "角色新增成功");
   response.getWriter().write(result.toString());

  } catch (Exception e)
  {
   e.printStackTrace();
  }

 }

2.直接傳一個數(shù)組到后臺

前臺JS代碼

function saveRoleEdit()
 { 
  var roleNames = $('#roleNames').textbox("getText");
  var roleDetail = {};
  roleDetail.roleFunctionCount = 0;
  roleDetail.roleFunctionList = [];
  if(roleNames.length < 0 || roleNames.length == 0)
  {
   $.messager.alert("提示","請輸入角色名");
   return;
  }
  var funNodeList = $("#roleFuntionTree").tree('getChecked','indeterminate');
  var funLeafList = $('#roleFuntionTree').tree('getChecked');
  if(funNodeList.length <=0 && funLeafList.length <= 0)
  {
   $.messager.alert("提示","請選擇權(quán)限節(jié)點");
   return;
  } 
  
  Array.prototype.push.apply(funNodeList, funLeafList); // funNodeList,funLeafList兩個數(shù)組都變成合并后的數(shù)組
  var roleFunArray = [];
  for(var i=0; i < funNodeList.length; i++)
  {
   if (!isEmptyTarget(funNodeList[i].id))
   {
    roleFunArray.push(funNodeList[i].id);
   }
  }

   alert("權(quán)限ID Array為 ：" + JSON.stringify(roleFunArray));
  $.ajax(
  {
    type : "POST",
    url : "permiss-manager/modifyRoleAuthority.action?_dc=" + Math.random(),
    data :
   {
    roleName:roleNames,
    roleDetailStr:JSON.stringify(roleFunArray),
   },
   success : function(result)
   {
   if(result == "success") 
   {
    $.messager.alert("提示","修改權(quán)限成功！","info");
    editRoleDialog();
    refreshRoleSelectTree();
    
   }
   else
   {
    $.messager.alert("提示","修改權(quán)限失?。?,"info");
   }
   } 
  });
 
 }

后臺Action方法

@Action("modifyRoleAuthority")
 public void modifyRoleAuthority() throws IOException
 {
  HttpServletResponse response = ServletActionContext.getResponse();
  response.setCharacterEncoding("utf-8");
  
  webLogService.writeWebLog(ServletActionContext.getRequest().getSession().getAttribute("userId").toString(), "權(quán)限給予", ServletActionContext.getRequest().getRemoteAddr());
  String roleName = ServletActionContext.getRequest().getParameter("roleName");
  String newFuncListStr = ServletActionContext.getRequest().getParameter("roleDetailStr");
  
  if(!StringUtils.isEmpty(roleName) && !StringUtils.isEmpty(newFuncListStr))
  {
   List<Integer> newFuncList = new ArrayList<Integer>();
   //這種方法可以把前臺傳過來的String類型的值 每個轉(zhuǎn)化成int 因為我這里之前dao爆了 就是因為String不能轉(zhuǎn)化為Int的原因 這里可以轉(zhuǎn)一下
   JSONArray mJSONArray= JSONArray.fromObject(newFuncListStr);
   newFuncList = Arrays.asList((Integer[])JSONArray.toArray(mJSONArray, Integer.class));
   if(!newFuncList.isEmpty())
   {
    if(permissionService.setRole(roleName, newFuncList))
    {
     response.getWriter().write("success");
    }
    else
    {
     response.getWriter().write("fail");
    }
   }
  }
 }
