I want to show an imagen taken with the camera and it's saved in file:///storage/emulated/0/Android/data/myapp.example/cache/1569223935056.jpg
getImage() {
this.data = localStorage.getItem("photoTakenPath")
var filename = this.data.substring(this.data.lastIndexOf('/') + 1);
var path = this.data.substring(0, this.data.lastIndexOf('/') + 1);
this.file.readAsDataURL(path, filename).then(res => {
this.cop = res;
});
console.log(this.cop)
}
And in my HTML
<ion-thumbnail slot="start">
<img [src]="cop" alt="Image" />
</ion-thumbnail>
But when I saw this:

i am trying to upload and preview image using jquery. But getting this
Error
Property 'result' does not exist on type 'EventTarget'.
reader.onload = function (e) {
$('#blah').attr('src', e.target.result);
}
page.ts
function readURL(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#blah').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
$('#file').on('change', function () {
readURL(this);
});
page.html
<label for="file" class="lbl"><i class="fa fa-plus-circle"></i> Add Attachment</label>
<input type="file" id="file" style="visibility: hidden">
<img src="#" id="blah">
what will be the solution?? i think this code is correct but just the problem is 'result' property. Thanks in advance
Some time ago, I used the following code to preview an image in Ionic.
In HTML:
<input type="file" value="" (change)="fileChange($event)">
<img *ngIf="img1" [src]="img1"/>
In JavaScript:
fileChange(event) {
if (event.target.files && event.target.files[0]) {
let reader = new FileReader();
reader.onload = (event:any) => {
this.img1 = event.target.result;
}
reader.readAsDataURL(event.target.files[0]); // to trigger onload
}
let fileList: FileList = event.target.files;
let file: File = fileList[0];
console.log(file);
}
Improvements are welcome
for ionic 4
In html
<img class="logo" src="{{img_new}}" *ngIf="img_new!=''"/>
<input type="file" name="image" accept="image/*" (change)="changeListener($event)">
In ts
changeListener($event): void {
this.file = $event.target.files[0];
console.log(this.file);
let reader = new FileReader();
reader.onload = ($event:any) => {
this.img_new = $event.target.result;
}
reader.readAsDataURL($event.target.files[0]);
}
I am developing an app using ionic v1.
I placed ion-slide-page in ion-slides and ion-scroll in ion-slide-page as shown below. This ion-scroll contains an image.
What I want to do is to keep the slide from moving left and right when the image is enlarged. (Like Facebook)
If I enlarge the image, I cannot scroll the image in X-axis.
Template:
<ion-slides options="options" slider="data.slider">
<ion-slide-page ng-repeat="image in post.imgs">
<ion-scroll
direction="xy"
scrollbar-x="false" scrollbar-y="false"
zooming="true" min-zoom="1" max_zoom="3"
overflow-scroll="false" locking="false" has-bouncing="true"
style="width: 100%; height: 100%" class="vertical-center"
delegate-handle="scrollHandle{{$index}}"
on-release="updateSlideStatus()">
<image style="width: 100%; height: 100%" ng-src="{{image}}"></image>
</ion-scroll>
</ion-slide-page>
</ion-slides>
Contorller:
$scope.$on("$ionicSlides.sliderInitialized", function(event, data){
console.log('ionic slides initialized');
$scope.slider = data.slider;
$scope.activeIndex = 0;
$scope.isSwipeLocked = false;
});
$scope.$on("$ionicSlides.slideChangeStart", function(event, data){
console.log('Slide change is beginning');
});
$scope.$on("$ionicSlides.slideChangeEnd", function(event, data) {
console.log('ionic slides change end');
$scope.activeIndex = data.slider.activeIndex;
$scope.previousIndex = data.slider.previousIndex;
});
$scope.updateSlideStatus = function() {
var zoom = $ionicScrollDelegate.$getByHandle('scrollHandle' + $scope.activeIndex).getScrollPosition().zoom;
if (zoom === 1) {
if ($scope.isSwipeLocked == true) {
$scope.slider.unlockSwipes();
$scope.isSwipeLocked = false;
}
} else {
if ($scope.isSwipeLocked == false) {
$scope.slider.lockSwipes();
$scope.isSwipeLocked = true;
}
}
};
Is there any idea?

I'm trying to load an image from a JSON file into my ionic application.
I can load messages/strings from the JSON file but can't get images to work.
I've created a codepen:
http://codepen.io/beefman/pen/aOpKgL?embed-id=15603
HTML:
<img class="full-image" ng-src="{{item.source}}">
Javscript:
.controller('announcementCtrl', function($scope, $http) {
$scope.data = [];
$scope.infiniteLimit = 1;
$scope.doRefresh = function() {
$http.get('')
.success(function(data) {
$scope.data = data;
$scope.$broadcast('scroll.refreshComplete');
})
.error(function() {
$scope.data = [];
$scope.$broadcast('scroll.refreshComplete');
});
}
Try ng-src=... instead of src=... in the image tag since it's an angular directive.

i have tried loading from a backup file but the problem persists.
You will need to find out why you got this error.
If you are running in a macro AND you are in WebForms mode, you can add ?umbDebugShowTrace=true (or ?umbDebug=true) at the url. (first check if the umbracoDebugMode appsetting in the web.config is true).
If this is not working, check the App_Data/Logs/ folder for any log files. You should see the complete error there. If you have an older version, check also the umbracoLog database table.
Best thing to do is to look in /App_Data/Logs/UmbracoTraceLog.txt which will show you the logs recorded for today.
This will reveal the root of the error and full stack trace.
