how can I do 5 photos instead of 3, how to change their size, how to do that they will be change automatically becouse now I have to press play to start?
html:
<script>
$(function () {
// Unstyled Example
$.monte('#example1');
// Styled Buttons Example
// (see the CSS in the above style block)
$.monte('#example2', {auto:false});
// Callback Example
// Format and append the HTML:
$('#example3 > img').each(function(){
$(this)
.wrap('<div style="position:relative"/>')
.parent()
.append('<div><p>' + $(this).attr('alt') + '</p></div>')
.append('<img src="frame.png" alt="" class="frame"/>');
});
// Hide the text on all but the center slide:
$('#example3 div div').css({opacity: 0}).eq(0).css({opacity: 0.8});
// Using the callbacks to reveal and hide the text:
$.monte('#example3', {
auto:false,
callbackIn: function () {
$(this[0]).find('div').animate({opacity: 0.8}, 450);
},
callbackAway: function () {
$(this[0]).find('div').animate({opacity: 0}, 450);
}
});
});
</script>

I am new to vuejs, I am trying to make my search component to replace my fixed-top navbar when the searchdiv hit the top of the screen while scrolling down, and when I scroll up, the navbar will only appear when the user is on top. I have seen this kind of functionaliy like google search. please see:
This is the normal view:
This is the scrolled view:
and this is mine:
Here is my code:
created() {
window.addEventListener('scroll', this.handleScroll);
},
destroyed() {
window.removeEventListener('scroll', this.handleScroll);
},
mounted() {
console.log("HomeLandingComponent mounted");
},
methods: {
handleScroll() {
let scrollY = window.scrollY
if (scrollY > this.startY) {
this.navbar_visible = false;
} else {
this.navbar_visible = true;
}
this.startY = scrollY;
}
}
what is does is just basically hide the navbar when scroll down and show navbar on scroll up. Is there a way on how to achieve it?
Simple.
Ensure that the search bar comes after the navbar and that the search bar is not nested; then on the search bar, position fixed; z-index: 1; you can use JavaScript to add a new class to give background a new colour.
Shouldn't be too hard. I'll write the code once I'm on my PC.
I am using webamp to show the map created in ArcGIS (Javascript API in PHP website). In the map, a popup also appears when clicking on the layer's points. Recently I have updated the version 4.14 from 4.13. After updating it, the popup is not working properly. I have a custom popup template. After research in the documentation, I came to know there required a return function to show the custom div on the popup. The below code I have added to show my custom popups.
var template = { content: function(){ var div = document.createElement("div"); div.className = "myClass"; div.innerHTML = "<span>My custom content!</span>"; return div; } }
layers[layerIndex].popupTemplate = template;
Now the popup appears fine. But I have to show the field values on the popup. I have used the required field attributes in double brackets eg: {Name}. But in the latest version, the field values are not appearing when I used the same.
The code I have used in version 4.13 and it was working,
popupTemplate = {
title: "{Name}",
content: '<div id="popup_address">{Address}</div><div class="right"><div href="#" id="popupRight" class="toggle"><p onClick="openPopupDetails({FACILITYID})">+</p></div></div>' };
layers[layerIndex].popupTemplate = popupTemplate;
Please help me to fix this issue.
Thanks.

I have modified the code,

var template = {
title: "{Name}",
content: function() {
var div = document.createElement("div");
div.innerHTML =
'<div id="popup_address">{Address}</div><div class="right"><div href="#" id="popupRight" class="toggle"><p onClick="openPopupDetails({FACILITYID})">+</p></div></div>';
return div;
}
};
layers[i].popupTemplate = template;
console.log(layer[i]);
}
When I apply custom div, the {Address} part is not rendering. It appears like {Address} itself.
I think you are a bit confuse, you still can use a string, or you can use a function for the content of the popup template. So if you want to use a function, you can use something like this,
popupTemplate = {
title: "{Name}",
content: popupContentChange
}
layers[layerIndex].popupTemplate = template;
function popupContentChange(feature) {
let div = document.createElement("div");
div.className = "myClass";
div.innerHTML = "<span>"+feature.graphic.attributes.Address+"</span>";
return div;
}
There are several examples in the API documentation, take a look there. Just to reference one, ArcGIS JavaScript API Examples - Intro to Popups
Here an example I made for you taking your code as base adding some fixes to display what you want.

If you want to use a function as content, you have to set the outFields parameter to include the fields you want to use in the function. The selected feature is pass as a parameter to the function, and inside you use feature.graphic.attributes to access the attributes. This should work,
var template = {
title: "{Name}",
// content: "<span>Address: {Address}</span>"
content: function(feature) {
console.log(feature);
var div = document.createElement("div");
div.className = "myClass";
div.innerHTML = "<span>Address:"+feature.graphic.attributes.Address+"</span>";
return div;
},
outFields: ["Name", "Address"]
};
featureNavigationEnabled is deprecated as of version 4.15. Use Popup.visibleElements.featureNavigation instead.

For a button, by default Bootstrap 4 allow you to set default button "size" between : xs, sm, md, lg, xl.
So, in my code, small screen first, i use sm size for screen <576px :
<button type="button" class="btn btn-success btn-sm"></button>
But for xl screen ≥1200px, need i to change size attribute or something else with Bootstrap to adjust button size ?
I don't really understand Bootstrap responsive behavior for button and 'size' attribute between small and large screen.
Thanks.
I don't think there's anything built out of the box for responsive buttons in bootstrap, you'd probably be better off extending the existing bootstrap button sizes in sass/media queries ie
.responsive-button {
#media (min-width: 576px) { #extend .btn-sm }
#media (min-width: 768px) { #extend .btn-md }
}
I haven't tested this so may need to research a bit further but hopefully this gets you on track :)
According to the Vue.js documentation, i had finally computed my CSS class dynamically according to window.onresizeevent call in mounted () function.
Example :
Here is my Bootstrap button :
<b-button :size="nsize" variant="outline-success" class="my-2 my-sm-0">
<font-awesome-icon icon="search"/>
</b-button>
Here is my function in App.vue file:
<script>
export default {
name: 'topnavbar',
data () {
return {
nsize: "sm",
mediaWidth: Math.max(document.documentElement.clientWidth, window.innerWidth || 0)
}
},
mounted () {
if (window.addEventListener) {
window.addEventListener("resize", this.updateSize, false);
} else if (window.attachEvent) {
window.attachEvent("onresize", this.updateSize);
}
},
methods : {
updateSize: function (){
let sizeEl = "md";
let width = Math.max(document.documentElement.clientWidth, window.innerWidth || 0);
if(width <= 576){
sizeEl = "sm";
}
this.nsize = sizeEl;
}
}
}
</script>

I am using vue-chartjs to render graphs on a webapp. I know you can print charts if you are using the original library. However I have no idea on how to do it with the vue version of the library.
I have my charts variable on an external charts.js file
import {Bar, mixins } from 'vue-chartjs'
Chart.defaults.global
let chartOptions = Chart.defaults.global;
const { reactiveProp } = mixins
export default {
extends: Bar,
mixins: [reactiveProp],
props: ['options'],
mounted () {
let that = this;
that.chartOptions = {
scales: {
yAxes: [{
ticks: {
suggestedMin: 0,
fontFamily: "'Overpass_Mono', 'Monaco', monospace",
fontColor: "rgba(254, 255, 248, 0.5)"
},
gridLines: {
color: 'rgba(255, 80, 248, 0.08)',
zeroLineColor: 'rgb(168, 119, 181)',
zeroLineWidth: 2
},
}],
xAxes: [{
ticks: {
suggestedMin: 0,
fontColor: "rgb(168, 119, 181)"
},
gridLines: {
color: 'rgba(255, 80, 248, 0.08)',
zeroLineColor: 'transparent',
}
}],
},
legend: {
labels: {
fontColor: 'rgb(168, 119, 181)',
}
}
},
this.renderChart(this.chartData, that.chartOptions)
}
}
Then on my component template I have:
<template>
<div class="report">
<charts v-if="todaySelected"
:chart-id="'total_visits_chart_bar'"
:height="chartsHeight"
:options="chartOptions"
:chart-data="datacollection"
></charts>
<div v-if="todaySelected">
<button #click="printChart(charts)">Print chart</button>
</div>
</template>
<script>
import charts from './chart_0.js'
components: {
charts,
},
data() {
return{
datacollection: {"datasets":[{"label":"Entries Today","data":[15,15,15,0]},{"label":"Currently Inside","data":[2,2,2,0]}],"labels":[]}
}
}.
methods: {
printChart(charts) {
charts.print();
},
}
</script>
Any help would be appreciated.
The answer is: Yes, it is. Your print method in the components' script could be:
methods:{
printChart() {
var canvasEle = document.getElementById('total_visits_chart_bar');
var win = window.open('', 'Print', 'height=600,width=800');
win.document.write("<br><img src='" + canvasEle.toDataURL() + "' />");
setTimeout(function(){ //giving it 200 milliseconds time to load
win.document.close();
win.focus()
win.print();
win.location.reload()
}, 200);
},
}
You can also add this to your component's style:
#media print{
#page {
size: landscape
}
}
vue-chartjs is based on chart.js and not canvas.js, thus it does not have a "build-in" way of printing.
You have to do it with some custom logic and the native javascript printing functions.
You can however grab the canvas element inside your chart component and generate for example an image and then print that image.
It will get a bit tricky, because you only have access to the canvas inside your chart component. So you will need to maybe wait for an event or prop to trigger the toDataURL call and then emit the image to your parent component where you can print it. If you want to trigger the print in your parent component.
methods: {
print () {
// grab the canvas and generate an image
let image = this.$refs.canvas.toDataURL('image/png')
// Emits an event with the image
this.$emit('chart:print', image)
}
}
In your parent component:
<template>
<your-chart #chart:print="handlePrint"
<template/>
....
...
methods: {
handlePrint(image) {
const win = window.open('', 'Print', 'height=600, width=800')
win.document.write(`<br><img src='${image}' />`)
win.print()
win.close()
}
}
It seems like the library is based on chartjs not canvasjs https://www.chartjs.org/docs/latest/ you might want to look into how to print a window Quick Print HTML5 Canvas, and remember you have access to the canvas element where your graph is drawn:
methods: {
printChart() {
const canvasEle = this.$el.querySelector('canvas');
//now your chart image is on canvasEle
},
}
If you are not against using export to pdf format, you can implement this task using jsPDF library, for example:
<template>
<div class="report">
<charts v-if="todaySelected"
:chart-id="'total_visits_chart_bar'"
:height="chartsHeight"
:options="chartOptions"
:chart-data="datacollection"
></charts>
</div>
</template>
<script>
import jsPDF from 'jspdf'; //for PDF printing
methods: {
pdfThatThing : function(){
//Default export is a4 paper, portrait, using milimeters for units
let pdfName = 'test';
var doc = new jsPDF();
doc.text("Header", 20, 20); //at x,y at def.units 2cm
//chart element
let canvasEle = document.getElementById('total_visits_chart_bar');
let chartURL = canvasEle.toDataURL(); //transform path
//a4 page is 209mm, adds at 4cm top, 2cm left, for 15cm in size
doc.addImage(chartURL, 'PNG', 20, 40, 150, 150 )
doc.save(pdfName + '.pdf');
},
}
</script>
There is also option to auto show print dialog in pdf viewer:
doc.autoPrint({variant: 'non-conform'})
I'm trying to use Magnific Popup in collaboration with elevateZoom, I have it working to a point where I have bound a click handler to the zoom container, which in this case is the .product-image-gallery div.
If I pass a single image src, e.g. $j('.product-image-gallery .gallery-image').attr('src'); as the src: argument then I get a popup with an image, but as soon as I pass a more general selector such as the .gallery-image on its own, i get a 'The image could not be loaded' message.
The aim is to have the popup let me cycle through all the avaliable product images.
HTML:
<div class="product-image-gallery">
<img id="image-main" class="gallery-image visible" src="example1.jpg" alt="Title" title="Title" />
<img id="image-0" class="gallery-image" src="example1.jpg" data-zoom-image="example1.jpg" />
<img id="image-1" class="gallery-image" src="example2.jpg" data-zoom-image="example2.jpg" />
<img id="image-2" class="gallery-image" src="example3.jpg" data-zoom-image="example3.jpg" />
</div>
JS ($j because jQuery is in noConflict mode):
$j.magnificPopup.open({
items: {
src: '.gallery-image',
type: 'image',
gallery: {
enabled: true
}
}
});
I ended up building an object then passing that to magnific-popup, my solution:
$j('.product-image-gallery').bind('click', function(){
galleryObj = [];
$j('.product-image-gallery .gallery-image').not('#image-main').each(function() {
var src = $j(this).data('zoom-image'),
type = 'image'; // it's always an image :)
image = {};
image ["src"] = src;
image ["type"] = type;
galleryObj.push(image);
});
// open the popup
$j.magnificPopup.open({
items: galleryObj,
gallery: {
enabled: true
},
});
});
