ForEach

this.sysCompanies.forEach((item: any)=>{
                    
})

让input框只能输入数字（效果是输入字母，不会显示在input框中）

<el-input v-model="scope.row.postArea" v-if="scope.row.edit" oninput = "this.value=this.value.replace(/[^\d]/g,'')"></el-input> //vue中使用需要加this

点击事件让标签隐藏

<tag v-if="a"></tag>   //点击事件后，将a变成false
