使用vue製作一個購物車功能,只是一個測試版本,注重的是功能實現,介面並沒有做好,資料也是模擬資料等
不說那麼多,直接上程式碼
<template> <div id="app"> 全選<input type="checkbox" v-model="checkall" @change="check_all()"> <div v-for="(item,index) in mylist" :key="index"> <span>{{item.oname}}</span><input type="checkbox" v-model="item.this_all" @change="check_list(index)"> <p v-for="(goods,nindex) in item.newlist" :key="nindex"> <input type="checkbox" v-model="goods.check_one" @change="click_input(index,nindex)">{{goods.newname}}--{{goods.price}}元 </p> </div> <p>總價:{{allprice}}</p> <button @click="btn()">提交訂單</button> </div> </template> <script> export default { name: 'App',data(){ return{ mylist:[ {oname:"第一個",this_all:true,newlist:[{newname:"籃球",check_one:true,price:600},{newname:"足球",price:200},{newname:"滑雪",price:150}]},{oname:"第二個",newlist:[{newname:"西瓜",price:35},{newname:"桃子",price:20}]},{oname:"第三個",newlist:[{newname:"英雄聯盟",price:200}]},],checkall:true,allprice:0,cpmylist:[] } },mounted:function(){ this.money(); },methods: { money:function(){ var that = this; this.allprice=0; that.mylist.forEach(item1 =>{ item1.newlist.forEach(item2 =>{ if(item2.check_one==true){ that.allprice+=item2.price; } }) }) },check_all:function(){ var that = this; that.mylist.forEach(item1 => { item1.this_all=that.checkall item1.newlist.forEach(item2 => { item2.check_one=that.checkall }) }); that.money(); },abc:function(){ var that = this; var aaa = that.mylist.filter(item2 =>{ return item2.this_all==true }) aaa.length==that.mylist.length ? that.checkall = true : that.checkall = false that.money(); },check_list:function(i){ var that = this; that.mylist[i].newlist.forEach(item1 =>{ item1.check_one=that.mylist[i].this_all }) that.abc(); },click_input:function(i,j){ var that = this; var checklist = that.mylist[i].newlist.filter(item1 =>{ return item1.check_one==true }) checklist.length==that.mylist[i].newlist.length ? that.mylist[i].this_all = true : that.mylist[i].this_all = false that.abc(); },btn:function(){ var that = this; that.cpmylist=JSON.parse(JSON.stringify(that.mylist)); that.cpmylist.filter(item1 =>{ item1.newlist = item1.newlist.filter(item2 =>{ return item2.check_one==true }) }) that.cpmylist=that.cpmylist.filter(item3 =>{ return item3.newlist.length!=0 }) if(that.cpmylist.length==0){ alert("請選擇商品哦!") }else{ console.log("★★★您購買的商品是:"); that.cpmylist.forEach(item4 =>{ console.log("----------"+item4.oname+"店鋪----------"); item4.newlist.forEach(item5 =>{ console.log("——>:"+item5.newname); }) }) } } },} </script> <style> #app { font-family: 'Avenir',Helvetica,Arial,sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } </style>
