I have some code where I update multiple files using a package.
Add / Remove seems to work if I console.log, but if I do a POST request, on server I get all files, even if I delete them.
Example: I add 3 files, I delete 2 of them and I do a POST, on server I get 3 files. (But on console.log it shows me that I have only 1 which is correct).
Also, I find this article , but I am not sure what to do in my case.
This is a short version of my code.
<div id="upload-files-on-update">
<file-upload
:multiple="true"
v-model="certifications"
input-id="certifications"
name="certifications[]"
#input-filter="inputFilter"
ref="upload">
<span class="button">Select files</span>
</file-upload>
</div>
new Vue({
el: '#upload-files-on-update',
data: function () {
return {
certifications: [],
}
},
components: {
FileUpload: VueUploadComponent
},
methods: {
updateFiles(){
let formData = new FormData();
this.certifications.forEach((file, index) => {
if (!file.status && file.blob) {
formData.append("certifications[]",
{
types: this.accept,
certifications_ids: this.certifications_ids,
}
);
this.loadingButton = true;
}
});
axios
.post("<?php echo $link;?>", formData, {
headers: {
"Content-Type": "multipart/form-data"
},
params:{
types: this.accept,
certifications_ids: this.certifications_ids,
}
})
},
inputFilter(newFile, oldFile, prevent) {
if (newFile && !oldFile) {
if (/(\/|^)(Thumbs\.db|desktop\.ini|\..+)$/.test(newFile.name)) {
return prevent()
}
if (/\.(php5?|html?|jsx?)$/i.test(newFile.name)) {
return prevent()
}
}
if (newFile && (!oldFile || newFile.file !== oldFile.file)) {
newFile.blob = ''
let URL = window.URL || window.webkitURL
if (URL && URL.createObjectURL) {
newFile.blob = URL.createObjectURL(newFile.file)
}
newFile.pending = true;
newFile.thumb = ''
if (newFile.blob && newFile.type.substr(0, 6) === 'image/') {
newFile.thumb = newFile.blob
}
}
},
// Remove file from table
removeFile(index) {
this.certifications.splice(index, 1);
},
}
});
I found a solution for this problem.
//I catch ajax request and I make sure that is the request that I want it
var self = this;
$.ajaxSetup({
beforeSend: function (xhr,settings) {
if(settings.type != 'POST'){
return ;
}
if(settings.data.get('controller') != 'wcfm-memberships-registration'){
return ;
}
// Here I set file input as an empty array
settings.data.set('certifications[]',[]);
// Here I add my new files from a VueJS array
self.certifications.forEach((file, index) => {
settings.data.append("certifications[]", file.file);
});
}
});
});

I have installed agora-rtc-sdk from npm.
My plugins/agora.js file looks like this
import Vue from "vue";
import AgoraRTC from 'agora-rtc-sdk';
Vue.use(AgoraRTC);
My nuxt.config.js has plugins declared as:
{
src: "~/plugins/agora.js",
ssr: false
}
The application on loading the page gives AgoraRTC is not defined. How do I add this AgoraRTC to my nuxt.js application?
Agora works only on the client side, fully independent of a server and hence you need to define the mode as client in the nuxt.config.js like this:
{ src: '~/plugins/agora.js', mode: 'client' },
I want to hide the header on scroll in Ionic 4 Beta 5.
I tried all the directives solutions, but none of them work for me.
So, are there any methods that work?
Use below directive
import { IonContent, DomController } from '#ionic/angular';
import { Directive, ElementRef, Input, Renderer2, SimpleChanges } from '#angular/core';
#Directive({
selector: '[scrollHide]'
})
export class ScrollHideDirective {
#Input('scrollHide') config: ScrollHideConfig;
#Input('scrollContent') scrollContent: IonContent;
contentHeight: number;
scrollHeight: number;
lastScrollPosition: number;
lastValue: number = 0;
constructor(private element: ElementRef, private renderer: Renderer2, private domCtrl: DomController) {
}
ngOnChanges(changes: SimpleChanges) {
if(this.scrollContent && this.config) {
this.scrollContent.scrollEvents = true;
let scrollStartFunc = async (ev) => {
const el = await this.scrollContent.getScrollElement();
this.contentHeight = el.offsetHeight;
this.scrollHeight = el.scrollHeight;
if (this.config.maxValue === undefined) {
this.config.maxValue = this.element.nativeElement.offsetHeight;
}
this.lastScrollPosition = el.scrollTop;
};
if(this.scrollContent && this.scrollContent instanceof IonContent) {
this.scrollContent.ionScrollStart.subscribe(scrollStartFunc);
this.scrollContent.ionScroll.subscribe(async (ev) => this.adjustElementOnScroll(ev));
this.scrollContent.ionScrollEnd.subscribe(async (ev) => this.adjustElementOnScroll(ev));
} else if(this.scrollContent instanceof HTMLElement) {
(this.scrollContent as HTMLElement).addEventListener('ionScrollStart', scrollStartFunc);
(this.scrollContent as HTMLElement).addEventListener('ionScroll',async (ev) => this.adjustElementOnScroll(ev));
(this.scrollContent as HTMLElement).addEventListener('ionScrollEnd',async (ev) => this.adjustElementOnScroll(ev));
}
}
}
private adjustElementOnScroll(ev) {
if (ev) {
this.domCtrl.write(async () => {
const el = await this.scrollContent.getScrollElement();
let scrollTop: number = el.scrollTop > 0 ? el.scrollTop : 0;
let scrolldiff: number = scrollTop - this.lastScrollPosition;
this.lastScrollPosition = scrollTop;
let newValue = this.lastValue + scrolldiff;
newValue = Math.max(0, Math.min(newValue, this.config.maxValue));
this.renderer.setStyle(this.element.nativeElement, this.config.cssProperty, `-${newValue}px`);
this.lastValue = newValue;
});
}
}
}
export interface ScrollHideConfig {
cssProperty: string;
maxValue: number;
}
Steps to use:
In your HTML
<ion-header [scrollHide]="headerScrollConfig" [scrollContent]="pageContent">
.
.
.
<ion-content #pageContent>
In your controller: Add config variables
footerScrollConfig: ScrollHideConfig = { cssProperty: 'margin-bottom', maxValue: undefined };
headerScrollConfig: ScrollHideConfig = { cssProperty: 'margin-top', maxValue: 54 };
I want to see what react-native run-androidis doing under the hood. where can I read what this is doing?
React Native is open source, so you can find the code for the CLI on Github: https://github.com/facebook/react-native/blob/master/local-cli/runAndroid/runAndroid.js
If you prefer to check it locally, you can find the code in your RN project under node_modules/react-native/ where the run-android code is in local-cli/runAndroid/runAndroid.js.
