Background values to achieve a plurality of transmission on the list js

Analysis of ideas
after a single use of a background check box is selected to transmit data directly clearly unreasonable (because I am a front desk is open foreach to traverse a list, a transfer can only pass one value), so the need for increased control the button or the detection control for detecting a list in which the check box is selected

Code

    $("#exportTreeGrid").click(function(){
            alert('123');
            var id_array = new Array();
            $("input[id='checkId']:checked").each(function(){
                id_array.push($(this).val());
            });
            //alert(id_array);
            if(id_array.length == 0){
                alert('请您选择要导出的复选框');
                return ;
            }else{
                 top.$.jBox.confirm("确认要导出已经确认的数据吗？","系统提示",function(v,h,f){
                    if(v=="ok"){
                        location.href="${ctx}/fdzapp/combineList/batchExport?combineCodes="+id_array;
                    }
                    },{buttonsFocus:1});
                    top.$('.jbox-body .jbox-icon').css('top','55px');
            }
        });



    $("#checkAll").click(function(){

            if(this.checked){
                $("input[id='checkId']").attr("checked","checked");
                 var arrs=new Array();
                    $("input[id='checkId']:checked").each(function(){ 
                        if($(this).attr("checked")){
                            arrs.push($(this).val());
                        }
                    });
                    
                    if(arrs.length==0 ){
                        alert('请选择数据!');
                        return ;
                    }
                    var combineCodes = arrs;
                    //var combineCodes = arrs.join(",");
                    //alert(combineCodes);
                        debugger;
                    top.$.jBox.confirm("确认要导出数据吗？","系统提示",function(v,h,f){
                        if(v=="ok"){
                            location.href="${ctx}/fdzapp/combineList/batchExport?combineCodes="+combineCodes;

                    top.$('.jbox-body .jbox-icon').css('top','55px');
               // alert(ids);
             }else{
                $("input[id='checkId']").attr("checked",null);
                
             }
        });
         
前台向后台传入的是字符串，后台取到后分隔就行了
    
    @RequiresPermissions("fdzapp:combineList:edit")
@RequestMapping(value = {"batchExport"})
public void batchExport(@RequestParam String combineCodes,HttpServletRequest request, HttpServletResponse response, RedirectAttributes redirectAttributes){
System.err.println(combineCodes);
try {
     String fileName = "合件明细数据"+DateUtils.getDate("yyyyMMddHHmmss")+".xlsx";
        if(StringUtils.isNotBlank(combineCodes)){
            String[] staffIds = combineCodes.split(",");
           List<CombineList> lists =  new ArrayList<CombineList>();
             for (String combineCode1 : staffIds) {
                 String  combineCode = combineCode1.substring(0, combineCode1.length());
                 System.err.println(combineCode);
                 CombineList combineList =  new CombineList();
                 combineList.setCombineCode(combineCode);
                 combineList.setListStatus("4");
                // System.err.println(combineList.getCombineCode()+"输出看看");
                 List<CombineList> list = combineListService.find4CwBatchExport(combineList);
                 System.err.println(list.get(0).getComponentCode()+"12345678");
                 lists.addAll(list);
             }
            if(lists.size() == 0) {//没取到值
                addMessage(redirectAttributes, "批量操作失败了！！！！");
                //return "redirect:" + Global.getAdminPath() + "/fdzapp/combineList/";
            }else {
                new ExportExcel("合件明细数据", CombineList.class).setDataList(lists).write(response, fileName).dispose();
                //return null;
            }
        }
} catch (Exception e) {
    addMessage(redirectAttributes, "数据导出失败！失败信息："+e.getMessage());
}
  // return "modules/fdzapp/combineCostList_Cw";
}

I am a rookie, posted in order to facilitate their future use, if not the exhibitions ah. .
