I did this, in some abandoned work. Turns out QWebWhatever didn't do it right
on iOS. It can't return a QVariantMap, you have to stringify it.
Timer {
id: testTimer
interval: 1000
repeat:false
running: false
onTriggered: {
webview.runJavaScript("try {testResult} catch (e)
{'undefined'}", function (result) {
console.log('object', JSON.stringify(result));
});
webview.runJavaScript("try {JSON.stringify(testResult)}
catch (e) {'undefined'}", function (result) {
console.log('stringified',
JSON.stringify(result));
});
}
onRunningChanged: console.log('running', running);
}
WebView {
id: webview
anchors.fill: parent
onLoadProgressChanged: {
console.log('loadProgress', loadProgress)
if (loadProgress == 100) testTimer.running = true;
}
}
