I have slider with swiper js, how it can return to first slide when we click Next Button on end of slide ?
http://idangero.us
You can set the loop parameter. For example:
var mySwiper = new Swiper ('.swiper-header', {
loop: true, //this should allow the last next button to return to the beginning
nextButton: '.swiper-button-next',
prevButton: '.swiper-button-prev',
});
i made function like this:
.swiper-next is: navigation - nextEl
var changed = false;
$(".swiper-next").on('click', function () {
if (changed === true) {
changed = false;
faqSwiper.slideTo(0);
}
if (faqSwiper.isEnd) changed = true;
})
You may use "click" event from Swiper API.
Note: setTimeout is needed to correctly determine slide index
const swiper_instance = new Swiper('.swiper-container', {
// ...
});
swiper_instance.on('click', function (swiper, event) {
const is_next_click = event.target === swiper.navigation.nextEl,
is_prev_click = event.target === swiper.navigation.prevEl,
is_end = this.isEnd,
is_beginning = this.isBeginning;
// slide to begin
if (is_next_click && is_end) {
setTimeout(() => swiper.slideTo(0))
}
// slide to end
if (is_prev_click && is_beginning) {
setTimeout(() => swiper.slideTo(swiper.slides.length))
}
});

the problem with the script I have is it starts out playing and then pauses when button is pressed I need the opposite. Plus I need the sound to be in sync with the length of the images in the array and both the image sequence and the sound file should play in a loop and start out as paused and play when the button is pressed.
HTML
<div>
<button id="bt1" onclick="togglePlay();toggle()"></button>
</div>
<script>
var myAudio = document.getElementById("myAudio");
var isPlaying = false;
let
loop,
index = 0,
images = [
"cat/1.svg", "cat/2.svg", "cat/3.svg", "cat/4.svg", "cat/5.svg", "cat/6.svg", "cat/7.svg", "cat/8.svg",
"cat/9.svg", "cat/10.svg", "cat/11.svg", "cat/12.svg", "cat/13.svg", "cat/14.svg", "cat/15.svg", "cat/16.svg",
"cat/17.svg", "cat/18.svg"
];
function startLoop() {
loop = setInterval(() => {
document.querySelector('img').src = images[index];
index++;
// Loop images array
if (index % images.length === 0) {
index = 0;
}
}, 100);
}
function toggle() {
if (loop) {
clearInterval(loop);
loop = null;
} else {
startLoop();
}
}
startLoop();
function togglePlay() {
isPlaying ? myAudio.pause() : myAudio.play();
};
myAudio.onplaying = function() {
isPlaying = true;
};
myAudio.onpause = function() {
isPlaying = false;
};
</script>
I have a vue function call which is triggered when selecting a radio button but it seems that my code inside my $nextTick is running before my previous line of code is finished. I don't want to use setTimout as I don't know how fast the user connection speed is.
findOrderer() {
axios.post('/MY/ENDPOINT')
.then((response) => {
this.orderers = response.data.accounts;
console.log('FIND_ORDER', this.orderers)
...OTHER_CODE
}
rbSelected(value) {
this.findOrderer();
this.newOrderList = [];
this.$nextTick(() => {
for (var i = 0, length = this.orderers.length; i < length; i++) {
console.log('FOR')
if (value.srcElement.value === this.orderers[i].accountType) {
console.log('IF')
this.newOrderList.push(this.orderers[i]);
}
}
this.$nextTick(() => {
this.orderers = [];
this.orderers = this.newOrderList;
console.log('orderers',this.orderers)
})
})
}
Looking at the console log the 'FINE_ORDERER' console.log is inside the 'findOrderer' function call so I would have expected this to be on top or am I miss using the $nextTick
That's expected, since findOrderer() contains asynchronous code. An easy way is to simply return the promise from the method, and then await it instead of waiting for next tick:
findOrderer() {
return axios.post('/MY/ENDPOINT')
.then((response) => {
this.orderers = response.data.accounts;
console.log('FIND_ORDER', this.orderers);
});
},
rbSelected: async function(value) {
// Wait for async operation to complete first!
await this.findOrderer();
this.newOrderList = [];
for (var i = 0, length = this.orderers.length; i < length; i++) {
console.log('FOR')
if (value.srcElement.value === this.orderers[i].accountType) {
console.log('IF')
this.newOrderList.push(this.orderers[i]);
}
}
this.orderers = [];
this.orderers = this.newOrderList;
console.log('orderers',this.orderers)
}
I am working with angular 6 and ngx-chart and I need on clicking the legend item, the corresponding data from the chart should show/hide
The ng-chart library does have this functionality and my client requests it.
Edit01:
I have almost everything working but I have a problem when applying axisFormat. once I remove an item from the legend it reformats the x-axis and doesn't literally put how the data comes without applying the AxisFormat. Any solution?
onSelect (event) {
let temp = JSON.parse(JSON.stringify(this.multi));
this.sourceData = JSON.parse(JSON.stringify(this.multi2));
if (this.isDataShown(event)) {
//Hide it
temp.some(pie => {
const pie2 = pie.name[0] + ',' + pie.name[1];
// console.log('pie', pie[0], event, pie2);
if (pie2 === event) {
pie.series = [];
return true;
}
});
} else {
//Show it back
console.log('Entramos en el ELSE');
const pieToAdd = this.sourceData.filter(pie => {
const pie2 = pie.name[0] + ',' + pie.name[1];
return pie2 === event;
});
temp.some(pie => {
const pie2 = pie.name[0] + ',' + pie.name[1];
if (pie2 === event) {
pie.series = pieToAdd[0].series;
return true;
}
});
}
console.log('log temp: ' + JSON.stringify(temp));
this.multi = temp;
// this.axisFormat(this.multi);
}
isDataShown = (name) => {
const selectedPie = this.multi.filter(pie => {
const pie2 = pie.name[0] + ',' + pie.name[1];
return pie2 === name && pie.series[0] !== undefined;
});
return selectedPie && selectedPie.length > 0;
}
axisFormat(val) {
const options = { day: 'numeric', month: 'short', hour: '2-digit', minute: '2-digit' };
// Esto funciona pero al hacer timeline no pone horas val.toLocaleDateString("es-ES", options);
console.log('val:', val.toLocaleDateString('es-ES', options));
return val.toLocaleDateString('es-ES', options);
}

Hello,
I have already managed to solve the problem adding an example in case it can help other people.
https://stackblitz.com/edit/click-lengd-ngx-charts
I am kinda new to Stack Overflow, but i think you should specify your answer more and show us what you already tried. Nevertheless I will try to help you.
You should give your chart a (select)="onClickFunction ($event)" in HTML. In your TS you then call the onClickFunction(event). I always start with giving it a console.log(event) to see what i get from clicking on the legend.
After clicking on the legend, you get the label of the element you clicked on. You can then search for this label in your data and remove this data out of the array you use for filling the chart.
If you provide a stackblitz or plunker wtih your code, I will gladly show you how to do it.
This is how we can achieve it for ngx-pie-chart. With the help of select event, capture it, identify the item from the data and make it zero. Next, on the next click, add the value back from the source copy. See it working here ngx-pie-chart label-filter
onSelect (event) {
let temp = JSON.parse(JSON.stringify(this.single));
if (this.isDataShown(event)) {
//Hide it
temp.some(pie => {
if (pie.name === event) {
pie.value = 0;
return true;
}
});
} else {
//Show it back
const pieToAdd = this.sourceData.filter(pie => {
return pie.name === event;
});
temp.some(pie => {
if (pie.name === event) {
pie.value = pieToAdd[0].value;
return true;
}
});
}
this.single = temp;
}
isDataShown = (name) => {
const selectedPie = this.single.filter(pie => {
return pie.name === name && pie.value !== 0;
});
return selectedPie && selectedPie.length > 0;
}
I am trying to implement a drag and drop solution in react-native and I want to make my flatlist scroll if I drag an item in the upper 10 percent and bottom 10 percent of the view. So far the only way i can get it to happen is by calling a function that recursively dispatches a this._flatList.scrollToOffset({ offset, animated: false });. The recursive call stops when a certain condition is met but the scrolling effect is choppy. Any advice on making that smoother?
// on move pan responder
onPanResponderMove: Animated.event([null, { [props.horizontal ? 'moveX' : 'moveY']: this._moveAnim }], {
listener: (evt, gestureState) => {
const { moveX, moveY } = gestureState
const { horizontal } = this.props
this._move = horizontal ? moveX : moveY;
const { pageY } = evt.nativeEvent;
const tappedPixel = pageY;
const topIndex = Math.floor(((tappedPixel - this._distanceFromTop + this._scrollOffset) - this._containerOffset) / 85);
const bottomIndex = Math.floor(((tappedPixel + (85 - this._distanceFromTop) + this._scrollOffset) - this._containerOffset) / 85);
this.setTopAndBottom(topIndex, bottomIndex);
this.scrolling = true;
this.scrollRec();
}
}),
// recursive scroll function
scrollRec = () => {
const { activeRow } = this.state;
const { scrollPercent, data, } = this.props;
const scrollRatio = scrollPercent / 100;
const isLastItem = activeRow === data.length - 1;
const fingerPosition = Math.max(0, this._move - this._containerOffset);
const shouldScrollUp = fingerPosition < (this._containerSize * scrollRatio); // finger is in first 10 percent
const shouldScrollDown = !isLastItem && fingerPosition > (this._containerSize * (1 - scrollRatio)) // finger is in last 10
const nextSpacerIndex = this.getSpacerIndex(this._move, activeRow);
if (nextSpacerIndex >= this.props.data.length) { this.scrolling = false; return this._flatList.scrollToEnd(); }
if (nextSpacerIndex === -1) { this.scrolling = false; return; }
if (shouldScrollUp) this.scroll(-20);
else if (shouldScrollDown) this.scroll(20);
else { this.scrolling = false; return; };
setTimeout(this.scrollRec, 50);
}
/
Yeah, pass an options object to your Animated.event with your listener with useNativeDriver set to true
Animated.event([
null,
{ [props.horizontal ? "moveX" : "moveY"]: this._moveAnim },
{
listener: ...,
useNativeDriver: true
}
]);
Should make things significantly smoother.
edit: I feel I should add that there is probably a saner way to accomplish this, are you only using a FlatList because of it's "infinite" dimensions?

can someone help me with this issue
The issue is with changeDetection for the component.
I have removed the changeDetection:ChangeDetectionStrategy.OnPush from my component its started working
