First of all i want to thank you for spending time reading this post. I am quite new to programming and i am learning ALOT. Sorry in advance for my incompetence.

Currently working on a webapp. This app has the function to basicly access the file system, and then upload the file selected. When clicking the upload button i have created, i get different results depending on weather or not im using PC or my iPhone.
When clicking the button on my iPhone the photo will be submitted to my storage on google cloud, but it will redirect me to the link of the picture.
On PC it does not redirect, and it still manages to upload the picture like it should.
I have an idea of when this problem occurs, i think it happens when submitting the form? The phone does not redirect back to the original page.
How do i get the iPhone result to be the same as my PC, so it doesnt redirect and stay on the page of my picture.

Also, all my code is in correct tags, i just copy pasted it into this website without script tags etc, cause there is a bunch of other code irrelevant to this one i had to manuever around.

<form id="BilledeUpload" action="" method="POST" enctype="multipart/form-data">

<input type="file"accept="image/*" name="file"class="">

<button form="BilledeUpload" name ="SendpictoDBbtn"onclick="indsaetIdb()">Upload</button>

 </form>



 function indsaetIdb(){

    let randomnummer = Math.floor(Math.random()*999999999)+1;      

    var billedenavn = document.getElementById("BilledeUpload");

    var url = "https://storage.googleapis.com/randombucketname/nottoday/"+randomnummer



    document.cookie="linket="+url;

    //document.getElementById("BilledeUpload").reset();

    console.log(findCookieBeskrivelse("linket"));



}
