The last several challenges covered the basic ways to pass props to child components. But what if the child component that you're passing a prop to is an ES6 class component, rather than a stateless functional component? The ES6 class component uses a slightly different convention to access props.
Anytime you refer to a class component within itself, you use the this
keyword. To access props within a class component, you preface the code that you use to access it with this
. For example, if an ES6 class component has a prop called data
, you write {this.props.data}
in JSX.
Render an instance of the ReturnTempPassword
component in the parent component ResetPassword
. Here, give ReturnTempPassword
a prop of tempPassword
and assign it a value of a string that is at least 8 characters long. Within the child, ReturnTempPassword
, access the tempPassword
prop within the strong
tags to make sure the user sees the temporary password.
class ReturnTempPassword extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
{ /* Change code below this line */ }
<p>Your temporary password is: <strong></strong></p>
{ /* Change code above this line */ }
</div>
);
}
};
class ResetPassword extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h2>Reset Password</h2>
<h3>We've generated a new temporary password for you.</h3>
<h3>Please reset this password from your account settings ASAP.</h3>
{ /* Change code below this line */ }
{ /* Change code above this line */ }
</div>
);
}
};
My Solution:
class ReturnTempPassword extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
{ /* Change code below this line */ }
<p>Your temporary password is:
<strong>{this.props.tempPassword}</strong>
</p>
{ /* Change code above this line */ }
</div>
);
}
};
class ResetPassword extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h2>Reset Password</h2>
<h3>We've generated a new temporary password for you.</h3>
<h3>Please reset this password from your account settings ASAP.</h3>
{ /* Change code below this line */ }
<ReturnTempPassword tempPassword={"Mcfuzzin"} />
{ /* Change code above this line */ }
</div>
);
}
};
Tests:
- The
ResetPassword
component should return a singlediv
element. - The fourth child of
ResetPassword
should be theReturnTempPassword
component. - The
ReturnTempPassword
component should have a prop calledtempPassword
. - The
tempPassword
prop ofReturnTempPassword
should be equal to a string of at least 8 characters. - The
ReturnTempPassword
component should display the password you create as thetempPassword
prop withinstrong
tags.
