}准备前端jsp：
// 用于添加时弹出框里嵌入表格的插件
="/easyui/plugin/editcell/jeasyui.extensions.datagrid.getColumnInfo.js">
="/easyui/plugin/editcell/jeasyui.extensions.datagrid.editors.js">
="/easyui/plugin/editcell/jeasyui.extensions.datagrid.edit.cellEdit.js">="text/javascript" src="https://www.it610.com/js/purchasebill.js">Title

交易时间
供应商
采购员
总数量
总金额
状态
因为添加时需要供货商和采购人员所有我们要准备两给查询方法：
//findAllSupplier
//查询供货商
@RequestMapping("/findAllSupplier")
@ResponseBody
public List> findAllSupplier(){
return supplierService.findAll();
}
//查询所有的采购部人员
@RequestMapping("/getBuyer")
@ResponseBody
public List getBuyer(){
return employeeService.getBuyer();
}
因为我们要做明细数据所以我们要引用easyui的插件上面已经引入了下面准备js代码：
$(function () {
//产品productIdproductColor颜色productImage 图像 amount 小计。。。。
var dg = $("#gridItems"),defaultRow = { productId: "", productColor: "", productImage: "", num: 0, price: 0, amount: 0, descs: "" },
insertPosition = "bottom";
var dgInit = function () {var getColumns = function () {
var result = [];
var normal = [
{
field: 'productId', title: '产品', width: 180,
editor: {
type: "combobox",
options: {
valueField:'id',
textField:'name',
panelHeight:'auto',
url:'/util/getProduct',
required: true
}
},
formatter:function(value,row){
return value.name;
}
},
{
field: 'productColor', title: '颜色', width: 180,
formatter:function(value,row){
if(row && row.productId){
return "+row.productId.color+"'>"
}
}
},
{
field: 'productImage', title: '产品图片', width: 100,
formatter:function(value,row){
if(row && row.productId){
return "![采购订单设计与完成]("+row.productId.smallPic+")
"
}
}
},
{
field: 'num', title: '数量', width: 100,
editor: {
type: "numberbox",
options: {
required: true
}
}
},
{
field: 'price', title: '价格', width: 100,
editor: {
type: "numberbox",
options: {
required: true
}
}
},
{
field: 'amount', title: '小计', width: 100,
formatter:function(value,row){
if(row && row.productId){
var amount = (row.num * row.price).toFixed(2);
return amount;
}
return 0;
}
},
{
field: 'descs', title: '备注', width: 100,
editor: {
type: "text"
}
}
];
result.push(normal);
return result;
};
var options = {
idField: "ID",
rownumbers: true,
fitColumns: true,
fit: true,
toolbar:'#itemBtns',
border: false,
singleSelect: true,
columns: getColumns(),
//表示开启单元格编辑功能
enableCellEdit: true
};
dg.datagrid(options);
};
var getInsertRowIndex = function () {
return insertPosition == "top" ? 0 : dg.datagrid("getRows").length;
}var buttonBindEvent = function () {$("#btnInsert").click(function () {
var targetIndex = getInsertRowIndex(), targetRow = $.extend({}, defaultRow, { ID: $.util.guid() });
dg.datagrid("insertRow", { index: targetIndex, row: targetRow });
dg.datagrid("editCell", { index: 0, field: "Code" });
});
$("#btnSave").click(function () {
var rows = dg.datagrid("getRows"), len = rows.length;
for (var i = 0;
i < len;
i++) {
dg.datagrid("endEdit", i);
}
});
$("#btnRemove").click(function () {
//获取选中行
var row = dg.datagrid("getSelected");
//获取选中行的索引 getRowIndex
var index =dg.datagrid("getRowIndex",row);
//根据索引删除行
dg.datagrid("deleteRow",index);
});
};
dgInit();
buttonBindEvent();
});
因为表格有些数据时链接的所以我们要做处理：
//供货商的处理
function formatObj(obj){
if(obj){
return obj.name;
}
return "";
}
//采购员
function formatEmp(obj){
if(obj){
return obj.username;
}
return "";
}
//formatStatus 审核的处理
function formatStatus(value){
var data = https://www.it610.com/article/{
0:"待审",
1:"已审",
"-1":"作废"
}
return data[value];
}
整个明细表单的crud：
$(function () {
//给所有a标签都注册一个事件
$("a").on("click", function () {
//动态获取data-method属性对应的值
var method = $(this).data("method");
//method不能为空
if(method){
//动态触发事件itsource[method]();
}
});
//datagrid对应的jquery对象
var purchasebillGrid = $("#purchasebillGrid");
//弹出框对应的jquery对象
var dlg = $("#dlg");
//form表单对应的jquery对象(弹出框)
var purchasebillForm = $("#purchasebillForm");
//编辑明细表格
var gridItem = $("#gridItems");
itsource = {
//高级查询
"search":function(){
//把form表单元素，直接封装成一个json对象
var jsonObj = $("#searchForm").serializeObject();
//加载datagrid
purchasebillGrid.datagrid('load',jsonObj);
},
//删除
"delete":function(){
//获取选中的行
var rows = purchasebillGrid.datagrid("getSelections");
//在js中认为false的值：0false ""null NaNundefined
if(!rows.length){
$.messager.alert('操作错误','亲!请选中数据进行删除!','error');
return;
}
//定义一个数组，该数组把所有的id都给装进来
var ids = [];
//循环数组中的所有数据
$.each(rows, function (i, o) {
//把id装进数组中
ids.push(o.id);
});
$.messager.confirm('确认', '你确定要离我而去吗?', function(r){
if (r){
$.get("/purchasebill/delete",{"ids":ids.toString()},function(result){
if(result.success){
//刷新界面
purchasebillGrid.datagrid("reload");
}else{
$.messager.alert('失败',result.msg,'error');
}
});
}
});
},
//添加按钮，弹出窗体
"add":function(){//弹出窗体，居中，并且设置标题,动态修改高度
dlg.dialog("open").dialog("center").dialog("setTitle","添加采购数据").dialog("resize",{
height:450
});
//清空form表单中所有的值
purchasebillForm.form("clear");
//清空f表格
gridItem.datagrid('loadData',[]);
},
//修改按钮，弹出窗体
"edit":function(){
//获取即将要修改的数据（单个对象）
//var row = purchasebillGrid.datagrid("getSelections");
var row = purchasebillGrid.datagrid("getSelected");
//没有选中就会返回null
if(!row){
$.messager.alert('操作错误','亲!请选中数据进行修改!','error');
return;
}//弹出窗体，居中，设置标题动态修改它的宽度和高度
dlg.dialog("open").dialog("center").dialog("setTitle","修改采购数据").dialog("resize",{
height:450
});
if(row.supplier){
row["supplier.id"]=row.supplier.id;
}
if(row.buyer){
row["buyer.id"]=row.buyer.id;
}
//回显数据
purchasebillForm.form('load',row);
//循环取出明细数据
for (var i = 0;
i < row.items.length;
i++) {
row.items[i].productId = row.items[i].product;
}
var items = $.extend([], row.items);
gridItem.datagrid("loadData", items);
},
//保存数据
"saveData":function(){
var url = "/purchasebill/save";
if($("#purchasebillid").val()){
url = "/purchasebill/update?cmd=update";
}
//提交form表单
purchasebillForm.form('submit', {
url:url,
onSubmit: function(params){//提交之前先做验证
//获取编辑表格所有数据
var rows = gridItem.datagrid('getRows');
for(var i=0;
