数字输入框禁止输入字母

如：

<v-text-field v-model="editedItem.passing" type="number"

                            value="0"

                            min="0"

                            onKeypress="return(/[\d\.]/.test(String.fromCharCode(event.keyCode)))" :label="$t('message.examPagePassing')" :rules="[v => !!v || $t('message.required')]" :disabled="editedDisable" required></v-text-field>

添加这个属性

onKeypress="return(/[\d\.]/.test(String.fromCharCode(event.keyCode)))"
