vue实现限制input只能输入中文

input增加参数

@keyup.native="inputChange($event)" @keydown.native="inputChange($event)"

增加方法

inputChange(event) {const val = event.target;val.value = val.value.replace(/[^\u4E00-\u9FA5]/g, '');this.name = val.value;},

源代码：

<el-input v-model="formValue.supplier.name" @keyup.native="inputChange($event)" @keydown.native="inputChange($event)"></el-input>

inputChange(event) {const val = event.target;val.value = val.value.replace(/[^\u4E00-\u9FA5]/g, '');this.formValue.supplier.name = val.value;},
