B4J Question How to access Javascript's Variable

[jinyistudio]

Hi

Following is HTML code. Could i use the variable of "graphic" in B4J ?

var container = document.getElementById('container');

    // Create a graphic instance over the container
    var graphic = archer.create(container);

    // Tell the graphic where assets (e.g. images) are located
    graphic.document.setAssetRoot(assetUrl);

    // Load graphic and configuration
    graphic.loadUrl(graphicUrl, configUrl);

    // Wait until files are loaded
    graphic.on('ready', function () {

        // Make graphic fit into container bounds
        graphic.view.zoomToFit();

        // Enable zoom / pan with mouse
        graphic.view.enableMouse(true, true);

        // Set variable values
        graphic.setValue('TempUnit', false);
        graphic.setValue('TempValue', '1.2');

        // Add event listeners

    });

I assume that this JS runs inside a WebView. You can inject JS that will interact with this object. You cannot use this object outside of the WebView.

Hi

I use following code. It's OK.

B4J

ws.RunFunction("HmiSetValue",Array As Object("TempValue",s1))

HTML

function HmiSetValue(na,va) {
    graphic.setValue(na,va);
};

function HmiGetValue(na) {
    return graphic.getValue(na);
};
