校园商铺-6店铺编辑列表和列表功能-4店铺信息编辑之前端实现

1.common.js匹配shopId

/**
 * 
 */
function changeVerifyCode(img){
	img.src="../Kaptcha?" + Math.floor(Math.random()*100);
}

function getQueryString(name){
	var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); //没有*,会只有个位数字匹配成功;加上*,就可以匹配任意长度
	var r = window.location.search.substr(1).match(reg);
	if(r != null){
		return decodeURIComponent(r[2]);
	}
	return '';
}

2.shopoperation.js要实现以下2个功能:

  • 1.根据店铺ID获取店铺信息
  • 2.修改店铺
/**
 * 
 */
$(function(){
	//从请求的URL中匹配到shopId
	var shopId = getQueryString('shopId');
	var initUrl = '/o2o/shopadmin/getshopinitinfo';//获取店铺的初始信息,还未定义
	var registerShopUrl = '/o2o/shopadmin/registershop';//注册店铺
	var shopInfoUrl = '/o2o/shopadmin/getshopbyid?shopid=' + shopId;
	var editShopUrl = '/o2o/shopadmin/modifyshop';
	//定义一个变量,用来传递状态:传递店铺,默认对店铺进行更新;不传,默认注册店铺
	var isEdit = shopId?true:false;
	if(!isEdit){
		getShopInitInfo();//没有shopId就是注册,调用初始化
	}else{
		getShopInfo(shopId);//有shopId就是修改,查询店铺信息
	}
	
	function getShopInfo(shopId){
		$.getJSON(shopInfoUrl,function(data){
			if(data.success){
				var shop = data.shop;
				$('#shop-name').val(shop.shopName);
				$('#shop-addr').val(shop.shopAddr);
				$('#shop-phone').val(shop.phone);
				$('#shop-desc').val(shop.shopDesc);
				var shopCategory = '<option data-id="' 
					+ shop.shopCategory.shopCategoryId + '" selected>'
					+ shop.shopCategory.shopCategoryName + '</option>';
				var tempAreaHtml = '';
				data.areaList.map(function(item, index){
					tempAreaHtml += '<option data-id="' + item.areaId +'">'
					+item.areaName + '</option>';
				});
				$('#shop-category').html(shopCategory);
				$('#shop-category').attr('disabled','disabled');
				$('#area').html(tempAreaHtml);
				$('#area option[data-id="'+shop.area.areaId+'"]').attr("selected", "selected");
			}
		});
	}
//	定义第一个方法getShopInitInfo:获取商铺分类、区域的列表信息
	function getShopInitInfo(){
//		alert(initUrl);//调试弹窗,证明js文件被加载
		$.getJSON(initUrl,function(data){ //访问的URL,回调方法
			if(data.success){ //true
				var tempHtml = '';//存放店铺类别列表
				var tempAreaHtml = '';//存放区域列表
				data.shopCategoryList.map(function(item,index){
					//用map遍历店铺类别列表,生成如<option data-id="1">盖浇饭</option>的列表
					tempHtml += '<option data-id="' + item.shopCategoryId + '">' +item.shopCategoryName + "</option>";
				});
				data.areaList.map(function(item,index){
					//用map遍历区域列表,生成如<option data-id="1">东苑</option>的列表
					tempAreaHtml += '<option data-id="' + item.areaId + '">' + item.areaName + '</option>';
				});
				//完成遍历之后,将获取到的信息,塞进前台定义好的id里面 #是css的用法,代表id
				$('#shop-category').html(tempHtml);
				$('#area').html(tempAreaHtml);
			}
		});
	}
	//第二个方法:点击提交,获取到表单信息,通过ajax转发到后台
	$('#submit').click(function(){
		var shop={};//json对象
		if(isEdit){
			shop.shopId = shopId;
		}
		//获取控件的信息
		shop.shopName = $('#shop-name').val();
		shop.shopAddr = $('#shop-addr').val();
		shop.phone = $('#shop-phone').val();
		shop.shopDesc = $('#shop-desc').val();
		shop.shopCategory = {
				shopCategoryId:$('#shop-category').find('option').not(function(){//返回被选中的
					return !this.selected;
				}).data('id')
		};
		shop.area = {
				areaId:$('#area').find('option').not(function(){
					return !this.selected;
				}).data('id')
		};
		var shopImg = $('#shop-img')[0].files[0];
		var formData = new FormData();//定义表单,用于接收
		formData.append('shopImg',shopImg);
		formData.append('shopStr',JSON.stringify(shop));//将json转换成字符流
		var verifyCodeActual = $('#j_kaptcha').val();
		if(!verifyCodeActual){
			$.toast('请输入验证码!');
			return;
		}
		formData.append('verifyCodeActual',verifyCodeActual);
		$.ajax({
			url: (isEdit ? editShopUrl:registerShopUrl),
			type:'POST',
			data:formData,
			contentType:false,//既要传文件,又要传文字,设为false
			processData:false,
			cache:false,
			success:function(data){
				if(data.success){
					$.toast("提交成功!");
				}else{
					$.toast("提交失败:"+data.errMsg);
				}
				$('#captcha_img').click()
			}
		});
	});
})

3.验证

以debug模式启动服务,在controller层getShopById和modifyShop第一行添加断点
浏览器打开地址http://127.0.0.1:18080/o2o/shopadmin/shopoperation?shopId=1
在js代码shopId定义处和submit方法第一行添加断点
结果:
