Input type=file, restrict to .rpt only

I'm using tag <input type="file" accept="application/x-rpt, magnus-internal/rpt"/> to only allow .rpt files to be uploaded, but it's unsuccessful. User still can upload whatever they want.

What's wrong here? Please help me. Thank you so much.

Put the following script in head

<script type="text/javascript">
    function ValidateForm() {
        var fileBox = document.getElementById("fileBox");
        var val = fileBox.value;
        var splittedValue = val.split(".");
        //alert(splittedValue.length);

        //for (var i = 0; i < splittedValue.length; i++) {
        //    alert(splittedValue[i]);
        //}

        var NthElementIndex = splittedValue.length - 1;
        var nThElement = splittedValue[NthElementIndex];

        if (nThElement != "jpg"
            && nThElement != "rpt") {
            alert("Please select valid rpt file");
        }
    }
</script>

Now Use the following information for id in input tag

<input type="file" id="fileBox" />
<input type="button" onclick="ValidateForm()" value="Validate" />
