Is it possible to display an element based on specific queryParams included in the URL?
For example:
ngOnInit() {
this.route.queryParams.subscribe(params => {
console.log(params);
});
}
If I want to achieve something similar to this:
<div *ngIf="queryParams = 'query_name'"></div>
To utilize a specific query parameter in a condition, you must first assign it to a property and then reference that property within the *ngIf directive.
queryParameter;
ngOnInit() {
this.route.queryParams.subscribe(params => {
this.queryParam = params['yourParamName'];
});
}
In your HTML markup:
<div *ngIf="queryParam == 'yourCondition'"></div>
When working in a .ts file, you can set up query parameters like this:
private queryParams:string ='';
ngOnInit() {
this.route.queryParams.subscribe(params => {
this.queryParams= params['parameterName'];
});
}
To clarify, if the route is "/userId" the code should look like this:
this.queryParams= params['userId'];
When working in a .html file, you can use the following code snippet to check for specific query parameter values:
<div *ngIf="queryParams.toLowerCase() === 'queryName'.toLowerCase()"></div>
For example, if the intended string is "userName," the code would look like this:
<div *ngIf="queryParams.toLowerCase() === 'userName'.toLowerCase()"></div>
