Uses a script to trigger a click event on a button after the page loads and a specified timeout period.

```html
<script appdrag-embed="true">
      //Wait for jquery to load before executing code
    addEventListener('JqueryLoaded', function(e) {
      setTimeout(function() {
        $("#MyPopupButton").trigger("click");
      }, 3000)
  }, false);

Parses a JSON response and saves the email and token to local storage if no error is present.

```javascript
var obj = JSON.parse(response);
if (obj.payload.error = = "EMAIL_ALREADY_USED") {
  $(".email-field").append("<p class=\"error-message\">Email already used</p>");
} else {
  localStorage.setItem("email", obj.payload.email);
  localStorage.setItem("token", obj.payload.token);
}
```

### Insert Row and Retrieve ID

var cloudbackend = require('appdrag-cloudbackend');  
cloudbackend.init(APIKey, appID);   
cloudbackend.sqlSelect("INSERT INTO Users (name, email, password) "   
+"values('john doe', 'john@doe.com', 'Test97_626p'); SELECT LAST_INSERT_ID() as newUserID;")   
.then( function(response) {   
var result = JSON.parse(response);   
var newUserID = result.Table[0].newUserID;   
callback(null, newUserID); //return the newUserID   
});
```
