IE 11 cannot submit an HTML form

Question

I have this HTML form

Click to copy

<form name="nextform" action="anotherpage.php" method="post" enctype="multipart/form-data">
    <input name="pinid" id="pinid" type="hidden">
    <input type="submit" name="submit" id="post" value="Lets Go" class="formButtonMap">
</form>

pinid dynamically gets a value using JavaScript. When it gets a value I alert it and it works.

But, when I click the Lets Go button, nothing happens. I see the Internet Explorer loading for a couple of minutes and then I get the message “The webpage does not respond”. If I hit refresh it goes to anotherpage.php but the values from the form did not arrive to the server.

Rarely shows this message:

Visual Studio Just-In-Time Debugger

An unhandled win32 exception occured in iexplorer.exe [688]

Possible Debuggers :

New Instance of Microsoft Visual Studio 2012

This behavior is observed only in Internet Explorer 11.0.2. The form works in older versions of Internet Explorer and also in Chrome and Firefox. I get no errors in IE’s console.

Here is the JavaScript code, placed above the form:

Click to copy

// called when another button is clicked - basicaly is websockets
function save() {
    var so = new WebSocket("ws://localhost:8000");
    so.onerror = function (evt) {
        alert('problem');
    }

    if (sara == 'LINES') {
        so.onopen = function() {
            so.send(JSON.stringify({
                command: 'insertAll',
                name: document.getElementById('name').value
            }));
        }
    }

    if (sara == 'POLY') {
        so.onopen = function() {
            so.send(JSON.stringify({
                command: 'insertHalf',
                name: document.getElementById('name').value
            }));
        }
    }

    so.onmessage = function (evt) {
        var received_msg = evt.data;

        document.getElementById("next").style.display = "block";
        document.getElementById("name").value = "";
        document.getElementById("descr").value = "";
        clearLinks();

        document.getElementById("pinid").value = received_msg;
        alert(document.getElementById("pinid").value); // works

        so.close();
    }
}

I tried to edit the code using document.getElementById("nextform").submit();, problem is still there.

Is it me? Is it a bug? What am I missing?

Answer 1

I believe this is a bug when setting form values to empty in IE.

• IE Bug Report

I would suggest trying a different method to resetting the form values, I have used this method in the past:

Click to copy

document.getElementById('name').parentNode.innerHTML = '';
