Not able to redirect to "index.html" after doing something with data. Find HERE in my code


#1
<body>
<form id="formId" onsubmit="addStudentData()"></form>
</body>
__
Scripts:
__
function addStudentData() {
    let name = document.getElementById('sname').value;
    let id = document.getElementById('sid').value;
    let year = document.getElementById('syear').value;
    let stream = document.getElementById('sstream').value;

    /* Form validation -- the fields should not be empty. */
    if (name == null || name == "", id == null || id == "", year == null || year == "", stream == null || stream == "") {
        alert("Please fill all required fields.");
        return false;
    }

    /* Making a JSON object using the form values */
    let studentObj = { 'name': name, 'year': year, 'stream': stream };

    /* Pushing record to sessionStorage after stringify JSON Object*/
    sessionStorage.setItem(id, JSON.stringify(studentObj));

    /* Redirecting back to home page*/
    alert("Done. Press OK, redirect to home page.");

    //HERE HERE HERE
    window.location = "index.html";

}

do you have the code linked to your HTML in the first place?
if not use

<script src='script.js'></script>

in your HTML to make it a little bit easier

this:

    let name = document.getElementById('sname').value;
    let id = document.getElementById('sid').value;
    let year = document.getElementById('syear').value;
    let stream = document.getElementById('sstream').value;

suggest there is more code, please provide it in a way we can replicate the problem. There are many sites like jsfiddle where you can share your code

by default, a form will attempt to submit a request to the back-end of the website on the same url. If you don’t want this, you will have to use preventDefault() on event (which can be given as a parameter to the function that needs to execute when form is submitted)

MDN has good documentation about this:
