vue从建立到完整的饿了么（17）本地缓存实现购物车
说明
1.上一章--watch监听子路由
2.苍渡大神源码--项目源码地址
3.数据接口--API接口
4.UI框架--Mint UI
5.下一章--购物车的详细信息展现与删除css
开始
1.先看一下目前的UI图
vue
要实现的UI图
node
2.footdiv代码修改以下git
<transition name="left">
<div v-if="footdiv" class="foot on">
<div class="footleft">
<div class="footlogo">
<icon name="footcar" class="footicon"></icon>
<div class="rednum">15</div>
</div>
<div class="footmain">
<div v-if="false" class="">未选购商品</div>
<div class="ih30 fs1-2">￥ 3205</div>
<div class="ih20">配送费 ￥5</div>
</div>
</div>
<div class="footright">
<span >￥20起送</span>
<span v-if="false">还差￥15起送</span>
<span v-if="false">去结算</span>
</div>
</div>
</transition>
css以下github
.foot{
height:50px;
line-height:50px;
background-color:#594C46;
display:flex;
position:fixed;
bottom:0px;
left:0px;
width:100%;
}
.foot.on .footicon{
color:#fff;
}
.foot.on .footmain{
color:#fff;
}
.foot.on .footlogo{
background-color:#3190E8;
}
.foot.on .footright{
color:#fff;
}
.footleft{
flex:2;
display:flex;
}
.footright{
flex:1;
text-align:center;
color:#B7B7B7;
background-color:#61686A;
}
.footright.on{
background-color:#4CD964;
color:white;
}
.footlogo{
text-align:center;
width:50px;
height:50px;
border-radius:50%;
background-color:#515151;
margin:0px 10px;
border:3px solid #444446;
transform:translatey(-15px)
}
.footicon{
color:#8a8a8a;
width:40px;
height:40px;
margin-top:7px;
}
.footmain{
height:50px;
color:#ADADAD;
font-size:0.8rem;
}
.rednum{
position: absolute;
top:-3px;
right:-5px;
border-radius:50%;
background-color:red;
color:white;
height:18px;
width:18px;
text-aligin:center;
line-height:18px;
font-size:12px;
}
我把全部可能出现的元素所有写出来了，用v-if来判断显示哪一个，到时候购物车有东西了，直接给footdiv加一个onclass就行。web
3.点击添加
注意，首先咱们要把布局修改一下
segmentfault
之前绿色的div在红色的div内，而红色div有一个点击跳转的效果，因此点击绿色div也会跳转。这在js中解决很是简单，可是在vue中怎么解决呢？我上网查了查没找到结果（哪位老铁知道怎么解决感谢指出）。。。最后是用布局解决的。
解决后红色div与绿色div是兄弟并非父子，将绿色div定位到红色div上便可。框架
4.数据类型
我们把数据存到localStorage里，键名为mycar，键值结构为dom
[{"shop":第一个商品的相关信息,"num":第一个商品的个数},{"shop":第二个商品的相关信息,"num":第二个商品的个数}]
（注意：localStorage只接收字符串，因此我们存取都要先转化再使用）
（注意：下面点击事件的参数e为API返回的一个完整的食品对象，狠狠的点击这里查看API，截图以下）
函数
点击事件以下
addcar:function(e){
var that=this;
if(localStorage.getItem("mycar")){
var mycar=JSON.parse(localStorage.getItem("mycar"));
var addok=true; //数据是否添加
for(var i =0;i<mycar.length;i++){
if(mycar[i].shop.item_id==e.item_id&&mycar[i].shop.category_id==e.category_id&&mycar[i].shop.restaurant_id==e.restaurant_id){
mycar[i].num=mycar[i].num+1;
addok=false;
break;
}
}
if(addok){
mycar.push({"shop":e,"num":1});
}
that.mycar=mycar;
localStorage.setItem("mycar",JSON.stringify(mycar));
}else{
var mycar=[{"shop":e,"num":1}];
that.mycar=mycar;
localStorage.setItem("mycar",JSON.stringify(mycar));
}
}
（注意：别忘了在data中设置变量mycar来存放购物车信息）
在footdiv中监听mycar来控制onclass是否添加和右上角的红色数字是否显示。
<transition name="left">
<div v-if="footdiv" class="foot" :class="{on:mycar.length>=1}">
<div class="footleft">
<div class="footlogo">
<icon name="footcar" class="footicon"></icon>
<div v-if="mycar" class="rednum">15</div>
</div>
<div class="footmain">
<div v-if="false" class="">未选购商品</div>
<div class="ih30 fs1-2">￥ 3205</div>
<div class="ih20">配送费 ￥5</div>
</div>
</div>
<div class="footright">
<span >￥20起送</span>
<span v-if="false">还差￥15起送</span>
<span v-if="false">去结算</span>
</div>
</div>
</transition>
这时发现商品数量没有计算，目前是写死的15，在计算属性computed中添加计算
computed:{
//计算属性
mycarshopnum:function(){
var num=0;
for(var i=0;i<this.mycar.length;i++){
num+=this.mycar[i].num;
}
return num
}
},
在footdiv中的rednum调用
<div v-if="mycar" class="rednum">{{mycarshopnum}}</div>
ok！运行试试
解决！
修改
1.能够看到，除了商品数量，其余全是假的，我们如今写活。
在computed中添加商品价格的计算（piecewise_agent_fee.tips为配送费，float_minimum_order_amount为起送费，在商家详情的API中，我们之前已经获取）
computed:{
//计算属性
//计算商品数量
mycarshopnum:function(){
var num=0;
for(var i=0;i<this.mycar.length;i++){
num+=this.mycar[i].num;
}
return num
},
//计算商品价格(商品只有一个种类)
mycarshoppic:function(){
var num=0;
for(var i=0;i<this.mycar.length;i++){
num+=(this.mycar[i].shop.specfoods[0].price*this.mycar[i].num);
}
return num
},
//判断商家起送价与目前购物车价格
shoppicbig:function(){
if(this.mycar){
if(this.mycarshoppic>=this.shopinfo.float_minimum_order_amount){
return 1
}else{
return 2
}
}else{
return false
}
}
},
footdiv修改以下
<transition name="left">
<div v-if="footdiv" class="foot" :class="{on:mycar.length>=1}">
<div class="footleft">
<div class="footlogo">
<icon name="footcar" class="footicon"></icon>
<div v-if="mycar" class="rednum">{{mycarshopnum}}</div>
</div>
<div class="footmain">
<div v-if="!mycar" class="">未选购商品</div>
<div v-if="mycar" class="ih30 fs1-2">￥ {{mycarshoppic}}</div>
<div v-if="mycar" class="ih20">{{this.shopinfo.piecewise_agent_fee.tips}}</div>
</div>
</div>
<div class="footright" :class="{on:shoppicbig==1}">
<span v-if="!mycar">￥{{this.shopinfo.float_minimum_order_amount}}起送</span>
<span v-if="shoppicbig==2">还差￥{{this.shopinfo.float_minimum_order_amount-mycarshoppic}}起送</span>
<span v-if="shoppicbig==1">去结算</span>
</div>
</div>
</transition>
运行试试
商品数量
如今只有购物车显示总数量，每一个商品显示几个并无。
1.样式
<transition name="right">
<span class="ih20">
<span><icon class="addicon" name="offline"></icon></span>
<span class="ih20 inblock y-4">15</span>
</span>
</transition>
由于商品数量为0时，减号也该没有，因此商品数量与减号写在一个动画内了，样式以下
2.判断商品数量。
如今商品的信息是从接口请求到后直接渲染在页面，没有作任何处理。如今咱们要把商品信息与购物车的信息结合一下，在computed写函数（shopmean是从接口请求到的商品信息，在前几章已经请求到，未作任何处理。specfoods是商品的型号，这里默认只有一个）
//商品与购物车数量结合
getshopnum:function(){
for(var i=0;i<this.shopmean.length;i++){
for(var k=0;k<this.shopmean[i].foods.length;k++){
for( var h=0;h<this.mycar.length;h++){
if(this.shopmean[i].foods[k].specfoods[0]._id==this.mycar[h].shop.specfoods[0]._id){
this.shopmean[i].foods[k].mynum=this.mycar[h].num;
}
}
}
}
return this.shopmean
}
再而后咱们在页面渲染数据时，只须要把
v-for="item in shopmean"
改为
v-for="item in getshopnum"
便可。
最后判断减号与数量的显示隐藏
<transition name="right">
<span v-if="items.mynum" class="ih20">
<span><icon class="addicon" name="offline"></icon></span>
<span class="ih20 inblock y-4">{{items.mynum}}</span>
</span>
</transition>
运行试试
除了动画没有运行，其余的完美！
删除商品
1.删除点击事件在dome绑定
<transition name="right">
<span v-if="items.mynum" class="ih20">
<span @click="removecar(items)"><icon class="addicon" name="offline"></icon></span>
<span class="ih20 inblock y-4">{{items.mynum}}</span>
</span>
</transition>
在methods中写函数
removecar:function(e){
for(var i=0;i<this.mycar.length;i++){
if(this.mycar[i].shop.specfoods[0]._id==e.specfoods[0]._id){
this.mycar[i].num==1?this.mycar.splice(i,1):(this.mycar[i].num=this.mycar[i].num-1);
break;
}
}
localStorage.setItem("mycar",JSON.stringify(this.mycar));
}
注意
这里要改一下计算属性中的getshopnum函数。我们在刚开始写时，只是把商品列表跟购物车列表循环，当ID相同时在商品列表添加属性mynum存储商品在购物车数量，不相同时不做操做。可是，咱们作了减商品的功能后，当商品数量为1时，减一后购物车清除该商品，而后经过计算属性中的getshopnum函数与商品列表循环，结果由于购物车已经清除该商品而函数找不到相同ID不做任何操做，但商品列表的该商品数量仍为一，因此当ID不相同时咱们给商品列表自定义属性mynum为0便可，将computed中的getshopnum修改成
//商品与购物车数量结合
getshopnum:function(){
for(var i=0;i<this.shopmean.length;i++){
for(var k=0;k<this.shopmean[i].foods.length;k++){
var isadd=true; //判断该商品是否在购物车
for( var h=0;h<this.mycar.length;h++){
if(this.shopmean[i].foods[k].specfoods[0]._id==this.mycar[h].shop.specfoods[0]._id){
this.shopmean[i].foods[k].mynum=this.mycar[h].num;
isadd=false;
break;
}
}
if(isadd){
this.shopmean[i].foods[k].mynum=0;
}
}
}
return this.shopmean
}
注意
当购物车清空时，mycar已存在而不是刚开始的空，因此购物车div里的元素显示隐藏要修改成判断mycar的长度而不是是否为空
<transition name="left">
<div v-if="footdiv" class="foot" :class="{on:mycar.length>=1}">
<div class="footleft">
<div class="footlogo">
<icon name="footcar" class="footicon"></icon>
<div v-if="mycar.length" class="rednum">{{mycarshopnum}}</div>
</div>
<div class="footmain">
<div v-if="!mycar.length" class="">未选购商品</div>
<div v-if="mycar.length" class="ih30 fs1-2">￥ {{mycarshoppic}}</div>
<div v-if="mycar.length" class="ih20">{{this.shopinfo.piecewise_agent_fee.tips}}</div>
</div>
</div>
<div class="footright" :class="{on:shoppicbig==1}">
<span v-if="!mycar">￥{{this.shopinfo.float_minimum_order_amount}}起送</span>
<span v-if="shoppicbig==2">还差￥{{this.shopinfo.float_minimum_order_amount-mycarshoppic}}起送</span>
<span v-if="shoppicbig==1">去结算</span>
</div>
</div>
</transition>
运行试试
商品分类小红点
咱们只须要在getshopnum给商品判断购物车中给商品数量时，给该商品的分类也加上该商品的数量便可。修改以下
//商品与购物车数量结合
getshopnum:function(){
for(var i=0;i<this.shopmean.length;i++){
var thisnum=0;
for(var k=0;k<this.shopmean[i].foods.length;k++){
var isadd=true; //判断该商品是否在购物车
for( var h=0;h<this.mycar.length;h++){
if(this.shopmean[i].foods[k].specfoods[0]._id==this.mycar[h].shop.specfoods[0]._id){
this.shopmean[i].foods[k].mynum=this.mycar[h].num;
thisnum+=this.mycar[h].num;
isadd=false;
break;
}
}
if(isadd){
this.shopmean[i].foods[k].mynum=0;
}
}
this.shopmean[i].mynum=thisnum;
}
return this.shopmean
}
结果以下
ok！购物车表面功夫写完了，下面升级购物车。
注意
购物车应该在渲染页面事就获取数据，因此在mounted中添加
//获取购物车信息
if(localStorage.getItem("mycar")){
that.mycar=JSON.parse(localStorage.getItem("mycar"));
}
