IBM Worklight - How to pass parameters from the application to the adapter?

Question

I want to pass parameters from the application to the adapter; I want the users of the app to enter these options.

Right now I am passing the parameters like this in ada

Answer 1

You can pass the parameters using simple JavaScript.
For example:

HTML

First name: <input type="text" id="firstname"/>
Last name: <input type="text" id="lastname"/>
<input type="button" onclick="submitName()" value="Submit Name"/>

App JS

function submitName() {
    var invocationData = {
            adapter : 'exampleAdapter',
            procedure : "showParameters",
            parameters : [$('#firstname').val(),$('#lastname').val()]
    };
    
    var options = {
            onSuccess : success,
            onFailure : failure
    };
    
    WL.Client.invokeProcedure(invocationData, options);
}


function success() {
    alert ("success");
}

function failure() {
    alert ("failure");
}

Adapter XML

<procedure name="showParameters"/>

Adapter implementation

function showParameters(firstname, lastname) {
    WL.Logger.info  ("The submitted parameters are: '" + firstname + "' and '" + lastname + "'");
}

To actually see the logged line you'll need to:

1. Open the Servers view in Eclipse

2. Expend the Worklight Development Server entry

3. Double-click on Server Configuration

4. Click on Logging

5. Change the Console log leve from AUDIT to INFO (using the dropdown)
