Requirement: We need to send some data from HTML input fields to Apex.
We have used JS remoting method to acheive this.
In a VF page, we have html input field. Submit button call a JS function which executes Remote method of Apex.
It is working well .
Problem we are facing is that we have a container VF page, through which we display dynamic content for page.
And page shows at site level.
Now, while same html input fields we are adding in container VF and submit button on click is calling javascript, then Remote action is not executing.


Error: TypeError: b is undefined

Our HTML:
<form class="cmxform" id="signUpForm" >
<fieldset class="ui-widget ui-widget-content ui-corner-all">
<legend class="ui-widget ui-widget-header ui-corner-all">Please provide your information in the form below to sign up</legend>
<p>
<label>Firstname</label>
<input name="Firstname" id="Fname" type="text" maxlegth="15" size="60" />
</p>
<p>
<label>Last Name</label>
<input name="Lastname" id="Lname" type="text" size="60" />
</p>
<p>
<input type="button" onClick="signUp();" value="Submit" class="button" />

</p>
</fieldset>
</form>

JS remote script:

function signUp()
{
alert("MFS");
var firstName = document.getElementById('Fname').value;
var lastName = document.getElementById('Lname').value;

alert("MFS : "+firstName+"::"+lastName);
Visualforce.remoting.Manager.invokeAction(
'{!$RemoteAction.MyController.myMethod}',
firstName,lastName,
function(result, event){
alert("MFS function called"+event.status);
if (event.status) {
alert("MFS event.status"+event.status);
} else if (event.type == 'exception') {
alert("MFS exception: "+event.message+event.where);

} else {
alert("MFS else ");
}
},
{escape: true}
);
}
</script>
