                  v-for=&quot;item in options&quot;
                  :key=&quot;item.value&quot;
                  :label=&quot;item.name&quot;
                  :value=&quot;item.value&quot;
                  @click=&quot;check_exist_variables(item)&quot;
                &gt;&lt;/el-option&gt;
              &lt;/el-select&gt;&lt;/el-form-item&gt;
  &lt;/el-form&gt;
  </code></pre>

  <pre><code>check_exist_variables: function (item) {
        //...
        this.$refs.form.reason.blur();
        // or 
        this.$refs.reason.blur();
      },
  </code></pre>
