我正在使用语义UI反应
https://react.semantic-ui.com/collections/form/#shorthand-subcomponent-id
在我的示例中,表单有两个字段。我还完成了必需的验证。当我单击button
时,如果字段为空,则显示red border
到字段。我希望焦点将移至第一个错误字段字段中有错误
这是我的代码
https://codesandbox.io/s/8yyqvvvj18
validateForm = () => {
const { subscriberFirstName, subscriberMiddleName } = this.state,
obj = { ...this.state };
/* Empty validation*/
let formError = false;
if (!subscriberFirstName) {
obj.subscriberFirstNameError = true;
obj.formErrorMessage = "mandatory";
formError = true;
} else {
obj.subscriberFirstNameError = false;
}
if (!subscriberMiddleName) {
obj.subscriberMiddleNameError = true;
obj.formErrorMessage = "mandatory";
formError = true;
} else {
obj.subscriberMiddleNameError = false;
}
if (formError) {
this.setState(preState => ({
...preState,
...obj,
formError: true
}));
} else {
this.setState(
preState => ({
...preState,
...obj,
formError: false,
formErrorMessage: ""
}),
() => {
// this.saveForm(false);
}
);
}
};
当用户单击按钮时,我希望焦点将移至第一个错误字段。
如果表单焦点出现错误,则会移至第一个错误字段
