基于Vue实现的多条件筛选功能的详解（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}} | </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',
sessionstorage和localstoragedata:list,
methods:{
handle:function(index,key){
var item=this.category[index].items;
item.filter(function(v,i){
if(i==key){
v.active=true;
dition.filter(function(v2,i){
if(v.name==v2.name){
dition.splice(i,1);
count--;
}
});
Vue.set(dition,count++,v);
}
});
},
remove:function(index){
var item=this.category[index].items;
item.filter(function (v1,key) {
v1.active=false;
dition.filter(function(v2,i){
if(v1.name==v2.name){
dition.splice(i,1);
count--;
}
});
});
},
allIn:function(index){
var item=this.category[index].items;
item.filter(function (v,key) {
v.active=true;
dition.filter(function(v2,i){
if(v.name==v2.name){
dition.splice(i,1);
count--;
}
});
Vue.set(dition,count++,v);
});
}
}
});
