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：

<el-tag
  :key="tag"
  v-for="tag in dynamicTags"
  closable
  :disable-transitions="false"
  @close="handleClose(tag)">
  {{tag}}
</el-tag>
<el-input
  class="input-new-tag"
  v-if="inputVisible"
  v-model="inputValue"
  ref="saveTagInput"
  size="small"
  @keyup.enter.native="handleInputConfirm"
  @blur="handleInputConfirm"
>
</el-input>
<el-button v-else class="button-new-tag" size="small" @click="showInput">+ New Tag</el-button>

<style>
  .el-tag + .el-tag {
    margin-left: 10px;
  }
  .button-new-tag {
    margin-left: 10px;
    height: 32px;
    line-height: 30px;
    padding-top: 0;
    padding-bottom: 0;
  }
  .input-new-tag {
    width: 90px;
    margin-left: 10px;
    vertical-align: bottom;
  }
</style>

<script>
  export default {
    data() {
      return {
        dynamicTags: ['标签一', '标签二', '标签三'],
        inputVisible: false,
        inputValue: ''
      };
    },
    methods: {
      handleClose(tag) {
        this.dynamicTags.splice(this.dynamicTags.indexOf(tag), 1);
      },

      showInput() {
        this.inputVisible = true;
        this.$nextTick(_ => {
          this.$refs.saveTagInput.$refs.input.focus();
        });
      },

      handleInputConfirm() {
        let inputValue = this.inputValue;
        if (inputValue) {
          this.dynamicTags.push(inputValue);
        }
        this.inputVisible = false;
        this.inputValue = '';
      }
    }
  }
</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：

<div class="formTime">
            <el-tag
              :key="tag"
              v-for="tag in dynamicTags"
              closable
              :disable-transitions="false"
              @close="handleClose(tag)">
              {{tag}}
            </el-tag>
            <el-dialog
              width="30%"
              append-to-body
              :visible.sync="inputVisible">
              <el-time-picker
                is-range
                v-model="tagTime"
                format="HH:mm:ss"
                value-format="HH:mm:ss"
                range-separator="至"
                start-placeholder="开始时间"
                end-placeholder="结束时间"
                placeholder="选择时间范围">
              </el-time-picker>
              <span slot="footer" class="dialog-footer">
                <el-button @click="inputVisible = false">取 消</el-button>
                <el-button type="primary" @click="tagTimeClick(tagTime)">确 定</el-button>
              </span>
            </el-dialog>

            </el-input>
            <el-button class="button-new-tag" size="small" @click="showInput" icon="el-icon-plus"/>
          </div>

data中加入：

dynamicTags: [],
inputVisible: false,
inputValue: "",
tagTime: [new Date(), new Date()]        

methods方法中代码如下：

handleClose(tag) {
      this.dynamicTags.splice(this.dynamicTags.indexOf(tag), 1);
    },
    showInput() {
      this.inputVisible = true;
    },
    tagTimeClick(tagTime) {
      console.log(tagTime, "tegTime");
      let inputValue = tagTime[0] + "-" + tagTime[1];
      console.log(inputValue);
      if (inputValue) {
        this.dynamicTags.push(inputValue);
      }
      this.inputVisible = false;
    },
