If I have an html document whose rough structure is
<html>
<head>
</head>
<body class="bodyclass" id="bodyid">
<div class="headerstuff">..stuff...</div>
<div class = "body">
<form action="" id="login_form" method="post">
<div class="form_section">You can login here</div>
<div class="form_section">
<input xmlns="" class="text" id="username"
name="session[username_or_email]" tabindex="1" type="text" value="" />
</div>
<div class="form_section">etc</div>
<div xmlns="" class="buttons">
<button type="submit" class="" name="" id="go" tabindex="3">Go</button>
<button type="submit" class="" name="cancel"
id="cancel" tabindex="4">Cancel</button>
</div>
</form>
</div>
</body>
</html>
You can see that there is a username field and a Go button. How would I, using Javascript, fill in the username and press Go...?
I would prefer to use plain JS, rather than a library like jQuery.

Reset to default 79document.getElementById('username').value="moo";
document.forms[0].submit();
Accessed through the document object.
document.getElementById('username').value = 'foo';
document.getElementById('login_form').submit();
You can try something like this:
<script type="text/javascript">
function simulateLogin(userName)
{
var userNameField = document.getElementById("username");
userNameField.value = userName;
var goButton = document.getElementById("go");
goButton.click();
}
simulateLogin("testUser");
</script>
It would be something like:
document.getElementById("username").value="Username";
document.forms[0].submit()
Or similar edit: you guys are too fast ;)
This method helped me doing this task
document.forms['YourFormNameHere'].elements['NameofFormField'].value = "YourValue"
document.forms['YourFormNameHere'].submit();
<html>tag. – user1385191 Commented Jan 13, 2011 at 17:53<input type="submit" />? Your form will not work if JS is disabled. – Felix Kling Commented Jan 13, 2011 at 17:54
