In my HTML head I first include jquery.min.js, jquery.couch.js and twitter-bootstrap js (in that order) and then I have a function called logmein() as follows:
<script>
$.couch.urlPrefix = "http://127.0.0.1:5984"
function logmein() {$.couch.login({
name: "testuser",
password: "test",
success: function() { alert("Success!") },
error: function() { alert("Login failed") }
});
}
</script>
With username and password hard-coded for testing.
I then have a button:
<button id="submit" class="btn btn-primary" onClick="logmein()">Sign in</button>
When I try and click submit, I get this error:
jquery.couch.js:216 TypeError: 'null' is not an object (evaluating 'resp.error')
However, if I type logmein() directly into Safari's web developer console, it works just fine! What am I doing wrong here?
Edit: I think it maybe related to this: https://stackoverflow.com/a/6792725/637562 though I don't quite understand why (to my knowledge, I was running it on the same protocol/host).
You can try changing your logmein function to run on the click event of #submit:
$('#submit').click(function(){
$.couch.urlPrefix = "http://127.0.0.1:5984";
$.couch.login({
name: "testuser",
password: "test",
success: function() { alert("Success!") },
error: function() { alert("Login failed") }
});
});
Also, it seems that the urlPrefix should be inside the logmein() function
function logmein()
{
$.couch.urlPrefix = "http://127.0.0.1:5984";
$.couch.login({
name: "testuser",
password: "test",
success: function() { alert("Success!") },
error: function() { alert("Login failed") }
});
}
"Solved"
If anyone else is having this issue, I'm still not exactly sure what caused the problem. Google Chrome gave a more detailed error message, suggesting the same origin policy had been violated, even though I don't believe this to be the case.
Despite this, there's a much simpler solution all without Javascript: the CouchDB Session API.
<form action="http://127.0.0.1:5984/_session/" method="post">
<input type="text" name="name">
<input type="password" name="password">
<button id="submit">Sign in</button>
Where 127.0.0.1 is a local couchdb instance, and should be replaced with your couchdb server address....
