The Loop problem in jQuery

when I click the View button to select the id of a certain piece of data in the table, I request multiple pieces of data according to id, and use each loop to render. After clicking, the next click will accumulate the last information
this is the code I wrote:

/ / data request for viewing the product details page of the data
function productDatas (orderNum,type) {

    $.ajax({
        type: "post",
        data: {orderNo: orderNum},
        url: "/manages/order/query_orderno",
        success: function (data) {
            var item="";
            console.log(data);
            var goodsDatas=data.data.detailList;//goodstype
            console.log(data.data.detailList);
            $.each(goodsDatas,function(i,result){  ///<button type="button" id="lookOrderDatas" class="btn btn-primary"></button>
                item += "<tr height="50"><td>"+result.goodstitle+"</td><td>"+result.goodsid+"</td><td>"+result.quantity+"</td><td>"+result.totalprice+"</td><td  style="width: 80px" ><button type="button" id="lookOrderDatas" class="btn btn-primary" style="display: none"></button></td></tr>";
                if(result.goodstitle==1){
                    $("-sharplookOrderDatas").css("display","block");
                }
            });
            $("-sharpproductDatas").append(item);
        }
    })

}

Don't understand too much. Circle the key code. What is the problem and what result do you want?


you should first clear out adding


does it mean that the pop-up dialog content is cumulative? $('- sharpproductDatas') Please execute empty before append.
