Apologies for the oversight. Let's modify the example to follow best practices by creating a tour service with dynamic functionality. This will allow us to separate the tour logic and make it reusable across different components.
Create a new Angular service for the tour:
shell
Copy code
ng generate service tour
Open the src/app/tour.service.ts file and update it with the following code:
typescript
Copy code
import { Injectable } from '@angular/core';
import introJs, { IntroOptions } from 'intro.js';
startTour(steps: introJs.Step[], options?: IntroOptions): void {
this.introInstance = introJs();
this.introInstance.setOptions(options);
this.introInstance.setOptions({
steps: steps,
// Add more options as per your requirements
});
this.introInstance.start();
}
nextStep(): void {
if (this.introInstance) {
this.introInstance.nextStep();
}
}
exitTour(): void {
if (this.introInstance) {
this.introInstance.exit();
}
}
}
Open the src/app/tour/tour.component.ts file and update it with the following code:
typescript
Copy code
import { Component, OnInit } from '@angular/core';
import { TourService } from '../tour.service';
import { introJs } from 'intro.js';
ngOnInit(): void {
const steps: introJs.Step[] = [
{
element: '#step1',
intro: 'Welcome to Step 1! This is a description of the first step.',
},
{
element: '#step2',
intro: 'Step 2 is here! You can provide instructions or explanations for this step.',
},
{
element: '#step3',
intro: 'Step 3 is all about this specific element. Highlight its importance and usage.',
},
{
element: '#step4',
intro: 'You made it to the final step! Feel free to provide any additional information or guidance.',
},
];
this.tourService.startTour(steps);
}
nextStep(): void {
this.tourService.nextStep();
}
exitTour(): void {
this.tourService.exitTour();
}
}
Open the src/app/tour/tour.component.html file and update it with the following code:
html
Copy code
<button (click)="nextStep()">Next Step
<button (click)="exitTour()">Exit Tour
Step 1 Element
Step 2 Element
Step 3 Element
Step 4 Element
Open the src/app/app.module.ts file and update it with the following code:
typescript
Copy code
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { TourComponent } from './tour/tour.component';
@NgModule({
declarations: [
AppComponent,
TourComponent
],
imports: [
BrowserModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Open the src/app/app.component.html

how do you know the tarhet elements in tour steps they are not dynamic
ChatGPT
Apologies for the confusion. If you want to dynamically determine the target elements for the tour steps, you can modify the code as follows:
Update the TourComponent to retrieve the target elements dynamically using ElementRef and ViewChild. Modify the ngOnInit method as shown below:
typescript
Copy code
import { Component, OnInit, AfterViewInit, ElementRef, ViewChild } from '@angular/core';
import { TourService } from '../tour.service';
import { introJs } from 'intro.js';
ngAfterViewInit(): void {
const steps: introJs.Step[] = [
{
element: this.step1Ref.nativeElement,
intro: 'Welcome to Step 1! This is a description of the first step.',
},
{
element: this.step2Ref.nativeElement,
intro: 'Step 2 is here! You can provide instructions or explanations for this step.',
},
{
element: this.step3Ref.nativeElement,
intro: 'Step 3 is all about this specific element. Highlight its importance and usage.',
},
{
element: this.step4Ref.nativeElement,
intro: 'You made it to the final step! Feel free to provide any additional information or guidance.',
},
];
this.tourService.startTour(steps);
}
nextStep(): void {
this.tourService.nextStep();
}
exitTour(): void {
this.tourService.exitTour();
}
}
Update the src/app/tour/tour.component.html file to add template reference variables for the target elements:
html
Copy code
<button (click)="nextStep()">Next Step
<button (click)="exitTour()">Exit Tour
<div #step1Ref id="step1">Step 1 Element
<div #step2Ref id="step2">Step 2 Element
<div #step3Ref id="step3">Step 3 Element
<div #step4Ref id="step4">Step 4 Element
Now, the target elements for the tour steps will be dynamically retrieved based on the template reference variables (step1Ref, step2Ref, step3Ref, step4Ref). Make sure to assign appropriate IDs to the target elements in your actual application for this to work correctly.
With these modifications, the tour will use the dynamically retrieved target elements for each step.
