I am using Ionic 4 and i want to trigger slideNext() in my custom function but I don't know how to call slideNext(). Can anyone help me. This is my html code.
<ion-slides pager="true">
<ion-slide class="step-one">
<ion-img src="/assets/icon/favicon.png"></ion-img>
<h1>Heading 1</h1>
<p>Text</p>
</ion-slide>
<ion-slide class="step-two" *ngIf = "verificationCodeSent == 1">
<ion-img src="/assets/icon/favicon.png"></ion-img>
<h1>Heading 2</h1>
<p>Text</p>
</ion-slide>
<ion-slide class="step-three" *ngIf = "verificationDone == 1">
<ion-img src="/assets/icon/favicon.png"></ion-img>
<h1>Heading 3</h1>
<p>Text</p>
<ion-button (click)="finish()">FINISH TUTORIAL!</ion-button>
</ion-slide>
</ion-slides>
heres one example of how to use it
.html
<ion-slides pager="true" #theSlides>
<ion-slide class="step-one" (click)="move(theSlides)">
<ion-img src="/assets/icon/favicon.png"></ion-img>
<h1>Heading 1</h1 >
<p>Text</p>
</ion-slide>
<ion-slide class="step-two" >
<ion-img src="/assets/icon/favicon.png"></ion-img>
<h1>Heading 2</h1>
<p>Text</p>
</ion-slide>
<ion-slide class="step-three" >
<ion-img src="/assets/icon/favicon.png"></ion-img>
<h1>Heading 3</h1>
<p>Text</p>
<ion-button (click)="finish()">FINISH TUTORIAL!</ion-button>
</ion-slide>
.ts
move(slides){
console.log(slides)
slides.slideTo(2)
}
Pass a reference (#theSlides) to the slide in the custom function (move(theSlides))

Please check code below, I want to flip my slides but this won't getting applied.I am new in Ionic and trying hard to get it resolve but no effects getting applied.
<ion-slides pager #mainslider [effect]=flip>
<ion-slide>
<h1>Slide 1</h1>
</ion-slide>
<ion-slide>
<h1>Slide 2</h1>
</ion-slide>
<ion-slide>
<h1>Slide 3</h1>
</ion-slide>
<button type="submit" ion-button color="primary" class="btnNext" (click)="next()">Next holiday</button>
<button type="submit" ion-button color="primary" class="btnNext" (click)="prev()">Next holiday</button>
</ion-slides>
next() {
this.slides.slideNext();
}
prev() {
this.slides.slidePrev();
}
ionViewWillEnter() {
this.slides.onlyExternal = true;
this.slides.effect = 'flip';
this.slides.paginationType = 'fraction';
this.slides.pager = false;
}
You should use effect property like this effect="flip"
<ion-slides pager #mainslider effect="flip">
<ion-slide style="background-color: aquamarine">
<h1>Slide 1</h1>
</ion-slide>
<ion-slide style="background-color:lightblue;">
<h1>Slide 2</h1>
</ion-slide>
<ion-slide style="background-color:darkcyan;">
<h1>Slide 3</h1>
</ion-slide>
</ion-slides>
I am using ionic 3 while placing 3 swiper sliders on same page i am unable to control their behavior separately i am bit new for angular js as well ts and ionic
here is code
<ion-slides style="height: 30%;" pager>
<ion-slide style="background-color: green" *ngFor="let post of posts">
<h1>{{post.title}}</h1>
<img [src]="post.image" />
</ion-slide>
</ion-slides>
<ion-slides style="height: 30%;" pager>
<ion-slide style="background-color: green" *ngFor="let post of posts">
<h1>{{post.title}}</h1>
<img [src]="post.image" />
</ion-slide>
</ion-slides>
ts is
#ViewChild(Slides) slides: Slides;
goToSlide() {
this.slides.slideTo(2, 500);
}
ngAfterViewInit() {
//this.slides.freeMode = true;
this.slides .slidesPerView=3,
this.slides.spaceBetween=5;
//this.slides.loop=true;
}
Instead of ViewChild, you can use ViewChildren to get all the instances of the slider in that page (Angular docs). Please take a look at this working plunker. The end result would be something like this:
Like you can see in the plunker, we get all the instances of the slider, and then we just get the target instance by using its index:
import { Component, ViewChildren, QueryList } from '#angular/core';
import { NavController, Content, Slides } from 'ionic-angular';
#Component({...})
export class HomePage {
#ViewChildren(Slides) slides: QueryList<Slides>;
constructor() {}
public move(index: number): void {
this.slides.toArray()[index].slideNext(500);
}
}
An then in the view:
<ion-header>
<ion-navbar>
<ion-title>Ionic Demo</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<ion-slides style="height: 75px" pager>
<ion-slide><h1>Slide 1</h1></ion-slide>
<ion-slide><h1>Slide 2</h1></ion-slide>
<ion-slide><h1>Slide 3</h1></ion-slide>
</ion-slides>
<ion-slides style="height: 75px" pager>
<ion-slide><h1>Slide 1</h1></ion-slide>
<ion-slide><h1>Slide 2</h1></ion-slide>
<ion-slide><h1>Slide 3</h1></ion-slide>
</ion-slides>
<ion-slides style="height: 75px" pager>

Is there any way to make my first row bigger than the second? I've been watching many tutorials but it seems that the flexbox solutions doesn't help me.
Actually you can just add a height in the first row.
<ion-grid>
<ion-row wrap style="background-color: #25dfc3; height: 300px;">
<ion-col>
<ion-slides pager>
<ion-slide>
<h1>Slide 1</h1>
</ion-slide>
<ion-slide>
<h1>Slide 2</h1>
</ion-slide>
<ion-slide>
<h1>Slide 3</h1>
</ion-slide>
<ion-slide>
<h1>Slide 4</h1>
</ion-slide>
</ion-slides>
</ion-col>
</ion-row>
<ion-row style="background-color: #ffffff;">
<ion-col>Amethyst!</ion-col>
</ion-row>
</ion-grid>

}
to{

}
}
}
screenshot 1
Then I copied the same code to another app, however, the result is different. It seem like the flex is not working...
screenshot 2
<ion-content >
<ion-slides loop #Slides>
<ion-slide >
<h2>Slide 1</h2>
</ion-slide>
<ion-slide >
<h2>Slide 2</h2>
</ion-slide>
<ion-slide >
<h2>Slide 3</h2>
</ion-slide>
</ion-slides>
<button ion-button full>login</button>
</ion-content>
When I use the code above, I have to scroll down to see the button.
Is there any way to force all the components to be on the same page ?
Add this to your page SCSS:
.scroll-content {
display: flex;
flex-direction: column;
ion-slides {
display: flex;
}
}
