vue button 防重复点击添加loading

在data里面添加状态

loading: false,

在提交按钮上添加元素:loading="loading"

<el-button :loading="loading" size="mini" style="width:75px;" class="mt20" type="primary" @click="handleSubmit()">提交</el-button>

提交时变换状态:
点击提交按钮，loading显示:this.loading = true
提交成功或者失败，loading消失:this.loading = false
