I need to add a preloading animation for vue.js SPA application meanwhile files in the background are being loaded, using SVG and a progress bar. So instead of user seeing empty screen, he can see an animation. Something like gmail loading animation or https://jsfiddle.net/ Thank you for any advice
VueJS has lifecycles. The most important for that are :
beforeCreate, created, beforeMount, mounted.
So, In your component, below the data, you can write some logic in these lifecycles.
So, for example in beforeCreate or created hook you can display your SVG loader, and then in mounted (inserted in DOM), you hide it.
Example :
//MyComponent.vue
<template>
...
</template
<script>
export default {
data() {
return {
article : {},
user_id: null
},
created() {
//Display your SVG
},
mounted() {
//Hide your SVG
},
methods: {
//etc,etc
}
</script>

I'm working in Angular 8, jqgrid working perfectly.
Is there a way I can alter the drag and drop image when DnD between two grids?
I'm playing with:
this.jqgSource.jqGrid(
'gridDnD',
{
connectWith: this.jqgSelectorTarget,
onstart: (ev, ui) => {
$(this).html("new content here");
},
ondrop: (ev, ui, dragdata) => {
const registrationId = dragdata.registrationId;
const moveToTeamId = this.targetTeamId;
this.swapComplete(registrationId, moveToTeamId);
}
});
but no luck...
Oleg got me going.
To change the content of the dragged object
Instead of:
$(this).html("new content here")
I needed to access the ui.helper:
ui.helper.html("new content here")
I am need a reusable, global dialog/modal component in my vue application. I need to be able to call it from any component and update its header text, body text and callback function once the dismiss button is pressed on the modal. I have tried importing a custom made dialog component into each component where I plan to use it and I have tried creating a global dialog where the values would be set using a mutable values in a modals vuex modal. This latter did not work because vuex will not store functions as values. I am new to vue and am not too sure how to go about this and absolutely any advice on a good way to go about it would help tremendously.
I did something like that before. The main ingredient is the handling of events through the $root because you can't relay in this scenario on the normal component communication.
// In your Global Modal
<script>
export default {
name: 'GlobalModal',
mounted () {
this.$root.$on('callGlobalModal', () => {
this.dialog = true
})
},
data: () => ({
dialog: false,
}),
}
</script>
Then call it frome anywhere using this.$root.$emit('callGlobalModal')
I'm attempting to use Aurelia and the Kendo UI Bridge to display data in a pie chart. Due to project requirements, I've got the pie chart widget loading in a custom element. If my data is available before the page loads, everything works fine.
View Model
export class PieChartCustomElement {
chartData = [];
chartSeries = [{
type: 'pie',
startAngle: 150,
field: 'percent',
categoryField: 'languageName'
}];
// other variables
constructor() {
//if I hard-code the data here, all works fine
this.chartData = [
{ languageName: 'English', percent: 62.5 },
{ languageName: 'Spanish', percent: 35 },
{ languageName: 'Esperanto', percent: 2.5 }
];
}
}
View
<template>
<require from="aurelia-kendoui-bridge/chart/chart"></require>
<h4>pie chart custom element</h4>
<ak-chart k-title.bind="title"
k-legend.bind="legend"
k-series-defaults.bind="chartDefaults"
k-series.bind="chartSeries"
k-data-source.bind="chartData"
k-tooltip.bind="tooltip"
k-widget.bind="pieChart"></ak-chart>
</template>
In reality, my data is fetched from a REST API using a promise, so I don't have the data when the page initially loads. Further, I need to pass a parameter to the REST API that comes in via a #bindable attribute on the element, so I cannot populate my data source in the constructor. Hence, something like this:
#bindable({ defaultBindingMode: bindingMode.oneWay }) someArg;
attached() {
// 'api' is injected and is a simple JS class that calls the REST API
this.api.getChartData(this.someArg).then((results) => {
this.chartData = results;
});
}
I'm pretty sure that this is due to the fact that the pie chart widget has already loaded and does not automatically reload when its backing data is changed. If this is actually the case, how do I get the pie chart to reload when I change its data set? If its not, what am I doing wrong?
Working Gist - Comment/uncomment code in the constructor/activate events as indicated to see the behavior.
I believe the method you are looking for is the setDataSource()
In pie-chart.js in the attached() method in your Gist try changing
this.chartData = languageData;
to
this.pieChart.setDataSource(this.chartData);
I'm developing an application using Angular, Semantic-UI and Animate.
I'm creating a form and I'm experiencing problems with dropdown that overlaps other inputs when it is open.
Here is a Plunker: https://plnkr.co/edit/BTCxfk
As you can see removing animated fadeIn animation from the class of Semantic-UI fields fixes the problem.
Then, what can I do to keep using both Semantic-UI and Animate and having that dropdown menu working with no bugs?
In this case it's recommended to use the built-in fade in animation (transition) in semantic-ui . this won't cause any bug on the dropdown .So first
remove animated fadeIn class , then change your code to the following :
export class App {
constructor() {
jQuery('.fields')
.transition('fade in')
;
setTimeout(() => {
jQuery('.ui.dropdown').dropdown();
}, 1000);)
}
}
Note that you can set parameters for your transition like: duration,callback... ,in transition settings:
jQuery('.fields')
.transition({
animation : 'fade in',
duration : '2s',
onComplete : function() {
alert('done');
}
})
;
For more settings see Docs
Anybody figure out syntax to re-render a template on window resize, using Meteor.js? I tried doing a Meteor.flush(), but that doesn't seem to be the right approach.... :(
window.onresize = function(){
Meteor.flush();
};
Change some session value when resizing the window, and then just have the template listen for that change:
<template name="body">
{{touch}}
</template>
Template.body.touch = function() {
return Session.get("touch");
}
Meteor.startup(function() {
$(window).resize(function(evt) {
Session.set("touch", new Date());
});
});
Meteor docs provides a good example for this scenario, by the way of adding window dimensions as a Client-side global Reactive data source, which could be called on
Template->autorun()
