I am facing a problem to submit two forms with one JavaScript function.

In that I have called one ajax file to check the username availability.

The forms are as below

```
<form action="abc.php" method="post" enctype="multipart/form-data" onsubmit="return isValid(this)" class="login_form" style="width:100%;">  

<form action="http://example.com" method="post" enctype="multipart/form-data" onsubmit="return isValid(this)" class="login_form" style="width:100%;" name="form1" id="form1">  

```

In isValid() function when I do 

```
    alert ("hi");
    document.form1.submit();
    alert("bye");

```

Then it submitting the form1 else it does not.
