Question about Dynamically adding html modules and submitting forms in jsp: jsp forms

Several questions about Dynamically adding html modules and submitting forms in jsp.

Corresponding project: market

Module: PesticideCheck

Case: Add sampling sub-objects dynamically (multiple Entity combinations)

Solution: Use the DOM model flexibly

function addItem(obj) {            itemId++;            var item = $(obj).parent().parent().next();            var group = item.find("p")[0];            item.append($(group).html());            var temp = item[item.length - 1];            var groupOther = item.find("p")[itemId];            var radioObjY = $(temp).find("input")[0];            var radioObjN = $(temp).find("input")[1];      if (item!=1) {                $(radioObjY).attr("name", "screeningResult" + itemId);                $(radioObjN).attr("name", "screeningResult" + itemId);            }        }        function removeItem(obj) {            var pSum = document.getElementById("items").getElementsByTagName("p").length;            if (pSum != 11) {                $(obj).parent().parent().parent().remove();            } else {                return;            }        }

At the same time, the corresponding select needs to dynamically Add the onchange event, you can use

Onchange = "getCommodityBatchByCommodity (this. value, this)" solves the problem. Find the select

You can use the same name attribute for form submission and submit objects and data in the form submission controller method, for example:

public String savePesticideCheck(@Valid @ModelAttribute("pesticideCheck") PesticideCheck pesticideCheck, BindingResult result, @RequestParam("shopId") int[] shopId,                                     @RequestParam("batchId") int[] batchId,@RequestParam("commodityId") int[] commodityId, ModelMap modelMap)
