一、uniapp输入框禁止输入汉字

<u-form-item label="****" prop="****"><u-input v-model="绑定值" type="text" @input="limitInput"/>
</u-form-item>limitInput(e) {this.$nextTick(() => {绑定值 = e.replace(/[\u4E00-\u9FA5]|\s/g,'')})
}

二、手动触发uni-app form表单某项检验

<u-form-item label="****" ref="testRef" prop="****">
</u-form-item>
this.$refs.testRef.onFieldChange();
