I wrote the code for login page,when i am running on desktop using phonegap desktop it working perfectly,but while i build that using phonegap build and when i tried to open in my phone the submit button is not working.Here is my code:
<script>
$(document).ready(function(){
});
function btnclick(){
debugger;
$.ajax({
type:"GET",
url: url/"+$('#useName').val()+"/"+$('#Password').val(),
contentType: "application/javascript",
jsonpCallback: "Login",

<input id="Password" type="password" placeholder="Password" />
<input type="submit" value="submit" id="btnclick" onclick="btnclick()" />
</form>

The only thing I can think of that is causing you troubles is the whitelist configuration needed for navigating external sources.
you should add on your config.xml something like:
<access origin = "*" />
<allow-navigation href="http://*/*" />
you can modify them to fit your needs but do try it out fist with a global access to verify that this is your problem.
Also add the cordova whitelist plugin
<gap:plugin name="cordova-plugin-whitelist" source="npm" version="1.0.0"/>
