Enter Key Sending Only One Form - html

Question

I've two forms in different divs. One is search form and another is login form.
Here is my problem: When I click search bar, type something and hit enter, form submits.
But when I enter my login information and press enter, nothing happens.
Here is the HTML code:
<div id="xxxx">
<form action="xxxxx.php" method="get" name="xxxxx">
<table>
<tr>
<td><input type="text" size="xxx" maxlength="xxxx" name="xxxx" id="xxxx"></td>
<td><input type="button" value="Ara"></td>
</tr>
</table>
</form>
</div>
<div id="xxxxxxx"><form name="xx" action="xxxxxx.php" method="post">
<table>
<tr>
<td>Kullanıcı Adı:</td>
<td><input type="text" name="xxxx" id="xxx" maxlength="xx" size="xx"></td>
<td>Şifre:</td>
<td><input type="password" name="xxxx" id="xxx" maxlength="xx" size="xx"></td>
<td><input type="button" name="xxxx" id="xxx" value="Oturum Aç"></td>
</tr>
</table>
</form></div>
Don't mind the xxx's
EDIT:
I'm calling a simple JS function to submit so I can't use input type submit.
Here is JS
function tik()
{
//after a few controls
document.forms["formName"].submit();
}
Of course formname changes for different forms

Answer 1

You have to simply change your <input type="button" ../> to <input type="submit" .../> and everything should works

Answer 2

I think it should work with <input type="submit"/>, initialize onsubmit attribute to call tik()
<div id="xxxx">
<form action="xxxxx.php" method="get" name="xxxxx" onsubmit="tik()">
<table>
<tr>
<td>
<input type="text" size="xxx" maxlength="xxxx" name="xxxx" id="xxxx">
</td>
<td>
<input type="submit" value="Ara">
</td>
</tr>
</table>
</form>
</div>
<div id="xxxxxxx">
<form name="xx" action="xxxxxx.php" method="post" onsubmit="tik()">
<table>
<tr>
<td>Kullanıcı Adı:</td>
<td><input type="text" name="xxxx" id="xxx" maxlength="xx" size="xx"></td>
<td>Şifre:</td>
<td><input type="password" name="xxxx" id="xxx" maxlength="xx" size="xx"></td>
<td><input type="submit" name="xxxx" id="xxx" value="Oturum Aç"></td>
</tr>
</table>
</form>
</div>

Answer 3

edit
Make sure to utilize <input type="submit">
Also:
Make sure the ID of your two buttons are different. Looks like in the first button you don't have an ID set.
make sure the "xxx.php" actions on the forms are not mixed up.
and lastly, make sure your form names are different (looks like they are given the amount of x's in each name value).
