I am having issue in image upload from multiple source to sing function and have to insert in array and push to http server.there are almost 8 image upload in different section of page and i have to insert each of them on single array and sent it to the server. Here is the code:

url1;

url2;

element: HTMLImageElement;

fileArray: any;



readUrl(event: any, number) {

    alert("1");

    console.log('readUrl');

    if (event.target.files && event.target.files[0]) {

        var reader = new FileReader();

        reader.onload = (event: any) => {

            console.log('imgurl' + number);

            document.getElementById('imgurl' + number).src = event.target.result;

            let tsnString = (document.getElementById("tsn_list") as HTMLTextAreaElement).value;

            this.fileArray[number] = event.target.result;

            console.log(this.fileArray);

        }

        reader.readAsDataURL(event.target.files[0]);

    }

}

<div class="openBase" *ngIf="aadhar==true">

    <div class="upload_data">

        <div class="upload">

            <div class="center_image">

                    <label for="file-input">

                        <img *ngIf="!url1==true" id="imgurl1" height="60" src="/assets/images/upload.png">

                        <img *ngIf="!url1==false" [src]="url1" height="60">

                    </label>

                    <input id="file-input" type="file" (change)="readUrl($event,'1')" />

                </div>

                <h6 *ngIf="!url1==true" class="font_u">

using single object we can do this

var obj={}; //Declare globally

var obj_name = any+number;

obj.obj_name = event.target.files[0];

before sending it to the server convert the array in to forum data format.

var data = new FormData();

for ( var key in obj) {

    data.append(key, obj[key]);

}

then pass this data to server using ajax.

by making proper changes you can do it in array also.

for ( var key in obj) {

    data.append(key, obj[key]);

}

then pass this data to server using ajax.

by making proper changes you can do it in array also.

using single object we can do this

var obj={}; //Declare globally

var obj_name = any+number;

obj.obj_name = event.target.files[0];

before sending it to the server convert the array in to forum data format.

var data = new FormData();

for ( var key in obj) {

    data.append(key, obj[key]);

}

then pass this data to server using ajax.
