本篇文章主要介绍vue添加标签，废话不多说了，下面上具体代码
效果如下：
html
<div id="app">
<div style="margin-bottom: 4px;">
<span class="selectedItem" v-for="item in selectedItems">{{item.name}} <i class="red fa fa-close (alias)"
v-on:click="deleteSelectedItem($index)"></i></span>
<input v-model="inputItem" type="text" v-on:focus="showDropmenu" v-on:keyup.enter="addItem">
</div>
<div v-show="isShowDropmenu">
<button v-for="item in cataName" v-on:click="showCataList($index)">{{item.name}}</button>
<button v-on:click="hideDropmenu"><i class="red fa fa-close (alias)"></i></button>
<div v-for="item in cataList" v-show="item.isShow">
<span v-for="one in item.items" class="item" v-on:click="addByClick(one)">{{one}}</span>
</div>
</div>
</div>
</div>
js
new Vue({
el:'#app',
data:{
selectedItems: [{
name: 'NodeJs'
}],
isShowDropmenu: false,
inputItem:'',
cataName:[{name:'开发语法'}, {name: '系统设备'}],
cataList:[{
isShow: true,
items:['js','c++','java']
},{
isShow: false,
items:['windows','chrome','linux']
}]
},
methods:{
showDropmenu: function(event){
console.log('showDropmenu');
this.isShowDropmenu = true;
},
hideDropmenu: function(event){
this.isShowDropmenu = false;
console.log('hideDropmenu');
},
test: function(){
console.log('test');
},
addItem: function(){
this.selectedItems.push({name: this.inputItem});
this.inputItem = "";
},
deleteSelectedItem: function(index){
this.selectedItems.splice(index, 1);
},
showCataList: function(index){
var i = this.cataList.length;
while(i--){
i === index ? this.cataList[i].isShow = true: this.cataList[i].isShow = false;
}
},
addByClick: function(name){
var i = this.selectedItems.length;
while(i--){
if(this.selectedItems[i].name === name){
return;
}
}
this.selectedItems.push({name: name});
}
}
});
</div>
