ElementUI Tag功能实现多标签生成

做项目过程中需要通过选择内容实现Tag多标签功能，效果如下：

ElementUi官方给出的的示例：

 1 <el-tag
 2   :key="tag"
 3   v-for="tag in dynamicTags"
 4   closable
 5   :disable-transitions="false"
 6   @close="handleClose(tag)">
 7   {{tag}}
 8 </el-tag>
 9 <el-input
10   class="input-new-tag"
11   v-if="inputVisible"
12   v-model="inputValue"
13   ref="saveTagInput"
14   size="small"
15   @keyup.enter.native="handleInputConfirm"
16   @blur="handleInputConfirm"
17 >
18 </el-input>
19 <el-button v-else class="button-new-tag" size="small" @click="showInput">+ New Tag</el-button>
20 
21 <style>
22   .el-tag + .el-tag {
23     margin-left: 10px;
24   }
25   .button-new-tag {
26     margin-left: 10px;
27     height: 32px;
28     line-height: 30px;
29     padding-top: 0;
30     padding-bottom: 0;
31   }
32   .input-new-tag {
33      90px;
34     margin-left: 10px;
35     vertical-align: bottom;
36   }
37 </style>
38 
39 <script>
40   export default {
41     data() {
42       return {
43         dynamicTags: ['标签一', '标签二', '标签三'],
44         inputVisible: false,
45         inputValue: ''
46       };
47     },
48     methods: {
49       handleClose(tag) {
50         this.dynamicTags.splice(this.dynamicTags.indexOf(tag), 1);
51       },
52 
53       showInput() {
54         this.inputVisible = true;
55         this.$nextTick(_ => {
56           this.$refs.saveTagInput.$refs.input.focus();
57         });
58       },
59 
60       handleInputConfirm() {
61         let inputValue = this.inputValue;
62         if (inputValue) {
63           this.dynamicTags.push(inputValue);
64         }
65         this.inputVisible = false;
66         this.inputValue = '';
67       }
68     }
69   }
70 </script>

但是实际项目中Tag显示的内容是需要弹框选择的，代码如下：

 1 <div class="formTime">
 2             <el-tag
 3               :key="tag"
 4               v-for="tag in dynamicTags"
 5               closable
 6               :disable-transitions="false"
 7               @close="handleClose(tag)">
 8               {{tag}}
 9             </el-tag>
10             <el-dialog
11               width="30%"
12               append-to-body
13               :visible.sync="inputVisible">
14               <el-time-picker
15                 is-range
16                 v-model="tagTime"
17                 format="HH:mm:ss"
18                 value-format="HH:mm:ss"
19                 range-separator="至"
20                 start-placeholder="开始时间"
21                 end-placeholder="结束时间"
22                 placeholder="选择时间范围">
23               </el-time-picker>
24               <span slot="footer" class="dialog-footer">
25                 <el-button @click="inputVisible = false">取 消</el-button>
26                 <el-button type="primary" @click="tagTimeClick(tagTime)">确 定</el-button>
27               </span>
28             </el-dialog>
29 
30             </el-input>
31             <el-button class="button-new-tag" size="small" @click="showInput" icon="el-icon-plus"/>
32           </div>

data中加入：

1 dynamicTags: [],
2 inputVisible: false,
3 inputValue: "",
4 tagTime: [new Date(), new Date()]

methods方法中代码如下：

 1 handleClose(tag) {
 2       this.dynamicTags.splice(this.dynamicTags.indexOf(tag), 1);
 3     },
 4     showInput() {
 5       this.inputVisible = true;
 6     },
 7     tagTimeClick(tagTime) {
 8       console.log(tagTime, "tegTime");
 9       let inputValue = tagTime[0] + "-" + tagTime[1];
10       console.log(inputValue);
11       if (inputValue) {
12         this.dynamicTags.push(inputValue);
13       }
14       this.inputVisible = false;
15     },
