基于Vue实现的多条件筛选功能(类似京东和淘宝功能)

基于Vue实现的多条件筛选功能(类似京东和淘宝功能)，可以支持多选、清空、全选功能，数据源是通过JSon格式的数据封装而成。

实现的效果图：

代码实现如下：

html:

<div id="app">
<template v-if="condition.length">
<div>
<span>已选中:<span>
<span v-for="(item,index) in condition" class="active">{{item.name}}&nbsp;|&nbsp;</span>
</div>
</template>
<template v-if="category.length">
<div class="nav" v-for="(items,index) in category">
<div class="mutil-query-title" v-if="items.name" :key="items.id">{{items.name}}<span style="margin-left: 20px;" @click="allIn(index)">全选</span>|<span @click="remove(index)">清空</span></div>
<ol v-if="items.items.length">
<li v-for="(item,key) in items.items">
<span :class="{"active":item.active}" @click="handle(index,key)" :key="item.id">{{item.name}}</span>
</li>
</ol>
</div>
</template>
</div>

js代码如下：

var list={
category:[
{
name:"品牌",
items:[
{
name:"联想",
active: false
},
{
name:"小米",
active: false
},
{
name:"苹果",
active: false
},
{
name:"东芝",
active: false
}
]
},
{
name:"CPU",
items:[
{
name:"intel i7 8700K",
active: false
},
{
name:"intel i7 7700K",
active: false
},
{
name:"intel i9 9270K",
active: false
},
{
name:"intel i7 8700",
active: false
},
{
name:"AMD 1600X",
active: false

}
]
},
{
name:"内存",
items:[
{
name:"七彩虹8G",
active: false
},
{
name:"七彩虹16G",
active: false
},
{
name:"金士顿8G",
active: false
},
{
name:"金士顿16G",
active: false
}
]
},
{
name:"显卡",
items:[
{
name:"NVIDIA 1060 8G",
active: false
},
{
name:"NVIDIA 1080Ti 16G",
active: false
},
{
name:"NVIDIA 1080 8G",
active: false
},
{
name:"NVIDIA 1060Ti 16G",
active: false
}
]
}
],
condition:[
]
};
var count=0;
var app =new Vue({
el:"#app",
data:list,
methods:{
handle:function(index,key){
var item=this.category[index].items;
item.filter(function(v,i){
if(i==key){
v.active=true;
this.list.condition.filter(function(v2,i){
if(v.name==v2.name){
this.list.condition.splice(i,1);
count--;
}
});
Vue.set(this.list.condition,count++,v);
}
});

},
remove:function(index){
var item=this.category[index].items;
item.filter(function (v1,key) {
v1.active=false;
this.list.condition.filter(function(v2,i){
if(v1.name==v2.name){
this.list.condition.splice(i,1);
count--;
}
});
});
},
allIn:function(index){
var item=this.category[index].items;
item.filter(function (v,key) {
v.active=true;
this.list.condition.filter(function(v2,i){
if(v.name==v2.name){
this.list.condition.splice(i,1);
count--;
}
});
Vue.set(this.list.condition,count++,v);
});
}
}

});
