ajax 向后台传值的几种方式

1.仅传个别值

前端

$.ajax({
            url: "/proj/ProjMaterialsMain/arrival",
            /**必须是POST方法**/
            type: 'post',
            data:{"bNo":row.bNo},
            dataType: 'json',
            success: function (result) {
                $.operate.successCallback(result);

            },
            error: function (XMLHttpRequest, textStatus, error) {
                $.operate.successCallback(result);
            }
        });

后台

 public AjaxResult examineSave(@Valid Long bNo)
    {
        return null;
    }

2.传对像值/表单值

前台

var param = {id: xxx, name: xxx}
 
$.ajax({
    type: "POST",
    dataType: "json",
    contentType:"application/json",
    url: "/xxx",
    data: JSON.stringify(param),
    success: function (result) {
        console.log(result)
    }
});

后台：

@PostMapping("/xxx")
public List xxx (@RequestBody Haha haha) {
    List list = new ArrayList();
    return list;
}

3.传主子表

if($.validate.form()){
                var params=new Object();
                // params.stockin=$("#formId").serializeJson();
                params.bReviewTime = $("#bReviewTime").val()
                params.bReviewer = $("#bReviewer").val()
                params.bIntegrationLeader = $("#bIntegrationLeader").val()
                params.bArrivalTime = $("#bArrivalTime").val()
                params.bStockId = $("#bStockId").val()
                params.bSubmitTime = $("#bSubmitTime").val()
                params.bPlaceOrderPeo = $("#bPlaceOrderPeo").val()
                params.bQuantity = $("#bQuantity").val()
                params.bProductId = $("#bProductId").val()
                params.bType = $("#bType").val()
                params.bProj = $("#bProj").val()
                params.projMaterialsBillList=$("#bootstrap-table").bootstrapTable("getData",false);
                var dada=JSON.stringify(params);
                console.log(dada)

                var opt=new Object()

                opt.url = '/proj/ProjMaterialsMain/add';
                opt.data=JSON.stringify(params);

                // window.alert(opt.data);
                ajaxRequestJsonBody(opt,onSaveSuccess);
                function ajaxRequestJsonBody(opt,callback){

                    $.ajax({
                        url			: opt.url,
                        /**必须是POST方法**/
                        type		: 'post',
                        /**必须制定请求的类型**/
                        contentType :'application/json',
                        data		: opt.data,
                        dataType	: 'json',
                        beforeSend: function () {
                            $.modal.loading("正在处理中，请稍后...");
                            $.modal.disable();
                        },
                        success: function(result) {
                            if (typeof callback == "function") {
                                callback(result);
                            }
                            $.operate.successCallback(result);

                        error:function(XMLHttpRequest,textStatus,error){
                            DataTable.config.ajaxError(XMLHttpRequest,textStatus,error,"设置失败");
                        }
                    });
                }

            }

后台：

    @Log(title = "工料单主表", businessType = BusinessType.INSERT)
    @PostMapping("/addSave")
    @ResponseBody
    public AjaxResult addSaveDetail(@RequestBody ProjMaterialsMain projMaterialsMain)
    {
        List<ProjMaterialsBill> projMaterialsBillList = projMaterialsMain.getProjMaterialsBillList();
        Long bno = projMaterialsBillService.getBno();
        for (int i = 0; i < projMaterialsBillList.size(); i  ) {
           projMaterialsBillList.get(i).setbNo(bno Long.valueOf(i));
        }
        projMaterialsMain.setProjMaterialsBillList(projMaterialsBillList);
        return toAjax(projMaterialsMainService.insertProjMaterialsMain(projMaterialsMain));
    }
