Example

In this example, we will use function methodCall to add a new div element in the document body by getting document object using resolveJSName function.

Code Equivalent

// Create div element
var div = document.createElement("div");

// Add some attribute to the div
div.className = "class";

// Add to the body
document.body.appendChild(div);

Steps

1. Drag a button component into the canvas and open the Action tab. Select the press event of the button and drag the setVar function to the event flow.

2. On setVar function var param add div as the value and on it's value param add a subflow and drag a function methodCall.

3. On it's context param add a subflow and drag a function resolveJSName, on it's name param add the value document.

   
4. On it's method param add a subflow and drag a function objectAttr, on it's object param add a subflow and drag a function resolveJSName, on it's name param add the value document. Back on the function objectAttr on it's attr param add the value createElement.

   
5. On it's arguments param add a subflow and drag a function toArray, on it's value1 param add the value div.

   
6. Back to main flow, drag the setObjectAttr function to the event flow, on it's object param add a subflow and drag a function getVar, on it's var param add the value div. As for the attr param add the value className and for the value param add the value class.

   
7. Back to main flow, drag the methodCall function to the event flow, on it's context param add a subflow and drag a function resolveJSName, on it's name param add the value document.body.

   
8. On it's method param add a subflow and drag a function objectAttr, on it's object param add a subflow and drag a function resolveJSName, on it's name param add the value document.body. Back on the function objectAttr on it's attr param add the value appendChild.

   
9. On it's arguments param add a subflow and drag a function toArray, on it's value1 param add a subflow and drag a function getVar, on it's var param add the value div.

   

Result

1. Now click the button in preview, check the inspector, you will see a new div element being added on the body
