Calling function in React
0
I have this function:
public getPermissions() {
const { listItems } = this.state;
{listItems.length > 0 && listItems.map((item: Project) => {
let web = new Web(item.ListUrl);
web.getCurrentUserEffectivePermissions().then(perms => {
if (web.hasPermissions(perms, PermissionKind.ViewPages)) {
return item.Title
} else {
return console.log('NOT Access');
}
}
I try to call this function inside a React component:
public render() {
return (
<div> ///error message
{this.getPermissions()}
</div>
)
}
However, I get an error message for the first div:
"[ts]
Type '{ children: void; }' is not assignable to type 'DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>'.
Type '{ children: void; }' is not assignable to type 'HTMLAttributes<HTMLDivElement>'.
Types of property 'children' are incompatible.
Type 'void' is not assignable to type 'ReactNode'.
(property) JSX.IntrinsicElements.div: React.DetailedHTMLProps<React.HTMLAttributes<HTMLDivElement>, HTMLDivElement>"
What does this error mean? How can I call the getPermissions function in the render function?

you arent returning a jsx element. un the render return you need to return jsx

That would solve the error message... however,getPermissionhas syntax errors by itself. You only need to wrap code into curly brackets when they are wrapped within JSX (beside the scope thing, but that's not that relevant now) :)

This method doesn't return JSX. You should call these kinds of events on lifecycle methods or you can simply call it before return of render() method like:
render() {
this.getPermissions();
return (...)
}
or in componentDidMount lifecyle like:
class YourComponent extends Component {
constructor(props) {
super(props);
this.state = { listItems: ... };
}
componentDidMount(){
this.getPermissions();
}
getPermissions = () => {
const { listItems } = this.state;
{listItems.length > 0 && listItems.map((item: Project) => {
let web = new Web(item.ListUrl);
web.getCurrentUserEffectivePermissions().then(perms => {
if (web.hasPermissions(perms, PermissionKind.ViewPages)) {
return item.Title
} else {
return console.log('NOT Access');
}
}
}
render() {
return (...)
}
}
