vue+ant-design-vue+electron 表单卡顿？

Question

调用handlePoliceSituation方法时页面卡住。
form为组件 v-if显示出来的
@blur="handlePoliceSituation"
方法里面什么都没写，只写了个alert，alert提示过后页面就卡主了。

<Form
            autoComplete="off"
            class="p-f enter-x"
            :model="formData"
            ref="formRef"
            @keypress.enter="handleSubmit"
            :label-col="{ span: 5 }"
            :wrapper-col="{ span: 17 }"
            :selfUpdate="true"
          >
            <FormItem name="barzjhm" class="enter-x" label="身份证号：">

                placeholder="请输入身份证号"
