spinner: ‘el-icon-loading’,

background: ‘rgba(0, 0, 0, 0.7)’

})

2。指定区域遮盖

const loading1 = this.$loading({

lock: true,

text: ‘生成并加载中，请稍后。。。’,

spinner: ‘el-icon-loading’,

target: document.querySelector(“#submit-form1”), //找到当前的位置，遮盖

background: ‘rgba(0, 0, 0, 0.7)’

})

3.关闭遮罩层

//关闭遮罩层
loadingInstance.close();
