准备列表数据
productList:[
{
'pro_name': '【斯文】甘油 | 丙三醇',
'pro_brand': 'skc',
'pro_place': '韩国',
'pro_purity': '99.7%',
'pro_min': "215千克",
'pro_depot': '上海仓海仓储',
'pro_num': 3,
'pro_img': '../../images/ucenter/testimg.jpg',
'pro_price': 800
}
]
记录产品是否有选中
准备了这么多,大家可能想到,还缺少一个,就是记录产品是否有选中,但是这个字段,虽然可以在上面那里加,但是意义不大,比如在平常项目那里!
后台的数据不会这样返回,数据库也不会有这个字段,这个字段应该是自己添加的。
代码如下:
new Vue({
el:'#shopping-cart',
data:{
productList:[
{
'pro_name': '【斯文】甘油 | 丙三醇',
'pro_brand': 'skc',
'pro_place': '韩国',
'pro_purity': '99.7%',
'pro_min': "215千克",
'pro_depot': '上海仓海仓储',
'pro_num': 3,
'pro_img': '../../images/ucenter/testimg.jpg',
'pro_price': 800
}
]
},
computed: {},
methods:{
},
mounted:function () {
var _this=this;
this.productList.map(function (item) {
_this.$set(item, 'select', true);
})
}
})
步骤1 数量加减
为了着重表示我修改了什么地方,代码我现在只贴出修改的部分,大家对着上面的布局,就很容易知道我改的是什么地方了!
点击增加和减少按钮(箭头指向地方),所属列的金额改变(红框地方) 执行步骤 1之前,要先把列表的数据给铺出来。
利用 v-for 指令。代码如下:
<tr v-for="item in productList">
<td class="td-check"><span class="check-span"></span></td>
<td class="td-product"><img :src="item.pro_img" width="98" height="98">
<div class="product-info">
<h6>{{item.pro_name}}</h6>
<p>品牌:{{item.pro_brand}} 产地:{{item.pro_place}}</p>
<p>规格/纯度:{{item.pro_purity}} 起定量:{{item.pro_min}}</p>
<p>配送仓储:{{item.pro_depot}}</p>
</div>
<div class="clearfix"></div>
</td>
<td class="td-num">
<div class="product-num">
<a href="javascript:;" class="num-reduce num-do fl" @click="item.pro_num--"><span></span></a>
<input type="text" class="num-input" v-model="item.pro_num">
<a href="javascript:;" class="num-add num-do fr" @click="item.pro_num++"><span></span></a>
</div>
</td>
<td class="td-price">
<p class="red-text">¥<span class="price-text">{{item.pro_price.toFixed(2)}}</span></p>
</td>
<td class="td-total">
<p class="red-text">¥<span class="total-text">{{item.pro_price*item.pro_num}}</span>.00</p>
</td>
<td class="td-do"><a href="javascript:;" class="product-delect">删除</a></td>
</tr>
这样,列表的数据就有了!
这两个按钮的功能已经实现了,后面的金额也会发生变化!
因为输入框利用 v-model 绑定了数量(pro_num) , 然后两个按钮分别添加了事件@click="item.pro_num--" 和 @click="item.pro_num++" ,接着后面的金额会改变,是因为{{item.pro_price*item.pro_num}} 。
只要 pro_price 或者 pro_num 的值改变了,整一块也会改变,视图就会刷新,我们就能看到变化(这些事情是 vue 做的,这就是 MVVM 的魅力,数据驱动视图改变)。
步骤 2 选中展示价格
点击所属列选择按钮(箭头指向地方), 总计的金额 (红框地方) 和 已选产品的列数 (蓝框地方) 和 全选 (黄框地方) 会改变 (如果已经全选了,全选按钮自动变成全选,如果没有全选,全选按钮,自动取消全选)!
选择与取消选择, 在这里只有两个操作(其实只有一个:改变这条记录的 select 字段)。 然后改变选择框,如果这条记录 select 为 false,就显示空,否则就显示选中对钩。
代码如下:
<td class="td-check">
<span class="check-span"
@click="item.select=!item.select"
:class="{'check-true':item.select}">
</span>
</td>
其实就是等于添加了 @click="item.select=!item.select" :class="{'check-true':item.select}" 这里。
点击这个,这条数据的 select 字段就取反( true->false 或者 false->true )。
然后 :class="{'check-true':item.select}" , 就会根据这条数据的 select 字段进行判断,是否添加 check-true 类名,如果 select 字段为true,就添加类名,显示对钩否则不添加类名不显示选中效果。
全选按钮,使用一个computed(计算属性)就好。代码如下:
<div class="td-check fl">
<span class="check-span fl check-all"
:class="{'check-true':isSelectAll}">
</span>全选
</div>
computed: {
isSelectAll:function(){
return this.productList.every(function (val) { return val.select});
}
}
<p class="fr product-total">¥<span>{{getTotal.totalPrice}}</span></p>
<p class="fr check-num">
<span>{{getTotal.totalNum}}</span>件商品总计(不含运费):
</p>
computed: {
isSelectAll:function(){
return this.productList.every(function (val) { return val.select});
},
getTotal:function(){
var _proList=this.productList.filter(function (val) { return val.select}),totalPrice=0;
for(var i=0,len=_proList.length;i<len;i++){
totalPrice+=_proList[i].pro_num*_proList[i].pro_price;
}
return {totalNum:_proList.length,totalPrice:totalPrice}
}
},
代码很简单,html 根据 getTotal 返回值显示数据,getTotal 依赖 productList 的数据,只要productList改变,返回值会改变,视图也会改变!
步骤 3 全选
点击全选按钮(箭头指向部分),会自动的对产品进行全选或者取消全选,下面的总计也会发生改变。
做到这一步,大家应该知道,全选或者取消全选,就是改变记录的 select。
但是怎么知道现在的列表有没有全选呢? 不需要在操作函数(全选与取消全选函数)里面遍历,大家应该还记得第二步的计算属性isSelectAll(为true就是全选,否则不是全选),把这个传进操作函数就好,然后操作函数,根据参数,决定执行全选,还是取消全选操作。代码如下!
<div class="td-check fl">
<span class="check-span fl check-all"
:class="{'check-true':isSelectAll}"
@click="selectProduct(isSelectAll)">
</span>全选
</div>
methods: {
selectProduct:function(_isSelect){
for (var i = 0, len = this.productList.length; i < len; i++) {
this.productList[i].select = !_isSelect;
}
}
},
步骤 4 删除
点击删除产品,会删除已经选中的,全选按钮和下面的总计,都会变化!点击每条记录后面的删除,会删除当前的这条记录。全选按钮和下面的总计,也都会变化! 首先,点击删除产品,删除已经选中。 这个大家知道了怎么做了!就是遍历 productList,如果哪条记录的select为true,就删除。
然后,点击每条记录后面的删除,删除当前的这条记录。
这个在 html 遍历 productList 的时候。
顺便带上索引,然后把索引当成参数,传进操作函数,然后根据索引参数,删除 productList 的哪一条记录。即可实现!
代码如下:
<tr v-for="(item,index) in productList">
<td class="td-check"><span class="check-span" @click="item.select=!item.select" :class="{'check-true':item.select}"></span></td>
<td class="td-product"><img :src="item.pro_img" width="98" height="98">
<div class="product-info">
<h6>{{item.pro_name}}</h6>
<p>品牌:{{item.pro_brand}} 产地:{{item.pro_place}}</p>
<p>规格/纯度:{{item.pro_purity}} 起定量:{{item.pro_min}}</p>
<p>配送仓储:{{item.pro_depot}}</p>
</div>
<div class="clearfix"></div>
</td>
<td class="td-num">
<div class="product-num">
<a href="javascript:;" class="num-reduce num-do fl" @click="item.pro_num--"><span></span></a>
<input type="text" class="num-input" v-model="item.pro_num">
<a href="javascript:;" class="num-add num-do fr" @click="item.pro_num++"><span></span></a>
</div>
</td>
<td class="td-price">
<p class="red-text">¥<span class="price-text">{{item.pro_price.toFixed(2)}}</span></p>
</td>
<td class="td-total">
<p class="red-text">¥<span class="total-text">{{item.pro_price*item.pro_num}}</span>.00</p>
</td>
<td class="td-do"><a href="javascript:;" class="product-delect" @click="deleteOneProduct(index)">删除</a></td>
</tr>
...
<a class="delect-product" href="javascript:;" @click="deleteProduct"><span></span>删除所选商品</a>
deleteProduct:function () {
this.productList=this.productList.filter(function (item) {return !item.select})
},
deleteOneProduct:function (index) {
this.productList.splice(index,1);
},
