Problem: Select element not responding to click events
When I was working on crossplatform mobile application using Cordova, I was trying to create a popup element. Below is the CSS and HTML markup
border:1px solid #CCC;
padding:20px 5px 20px 5px;
border:1px solid #FFF;
border-width: 0px 0px 1px 0px;

HTTP OPTIONS Request; Modifying HTTP Headers –
When we modify and send headers from client side, initially browser requests server with OPTIONS method to know if the specified Headers are valid or not. Depending upon the response, new request is sent to server with proper headers.
Server Calls in Cordova App-
To fetch data from Server is very commonly used in almost every Cordova Application. Using desktop web browser either with file protocol or using some server to run and test html pages written for Cordova App will result in more complications. You might see CORS error in browser console. Requests will be blocked. I’ve wasted a day trying to test in web browser. Finally (luckily infact) I gave a shot running on android device with faintest hope. To my utter surprise, everything was running just as expected.
Device specific issues- If you have not installed “cordova-plugin-whitelist” plugin, server calls will fail with 404 code locally without actually checking for that file/api in devices with newer version of Android (faced this issue in lollipop devices). Use below command to install the plugin-
cordova plugin add cordova-plugin-whitelist
Difficulty Running Cordova App on old devices –
Note that Cordova version is different from platform version. Each platform like Android, IOS will have different versions. You can update them using this command-
cordova platform update firstname.lastname@example.org
(Here 4.0.2 is the desired version of android platform). As of cordova-android-4.1.0, minSDKVersion is 14.
