- `webView:registerCallback(name, function)`: Register a Lua function that can be called from JavaScript
- `webView:on(eventName, listener)`: Listen for events from JavaScript
- `webView:send(eventName, data)`: Send data to WebView
- `webView:injectJS(script)`: Inject JavaScript code into WebView
How to use:
```lua
local myWebView = native.newWebView(
display.contentCenterX,
display.contentCenterY,
display.actualContentWidth,
display.actualContentHeight
)
webView:registerCallback("getDeviceInfo", function(data)
return {
platform = system.getInfo("platform"),
version = system.getInfo("architectureInfo"),
language = system.getPreference("locale", "language"),
deviceModel = system.getInfo("model")
}
end)
webView:on("buttonClicked", function(data)
print("Button clicked in WebView: " .. data.buttonId)
-- Respond to WebView
webView:send("buttonResponse", {message = "Received click for button " .. data.buttonId})
end)
local function injectJS()
webView:injectJS[[
function updateDeviceInfo() {
NativeBridge.callNative("getDeviceInfo").then(info => {
document.getElementById("deviceInfo").innerHTML =
`Platform: ${info.platform}<br>
Version: ${info.version}<br>
Language: ${info.language}<br>
Model: ${info.deviceModel}`;
});
}
document.getElementById("updateButton").addEventListener('click', function() {
updateDeviceInfo();
NativeBridge.sendToLua("buttonClicked", {buttonId: "update"});
});
document.getElementById("greetButton").addEventListener('click', function() {
NativeBridge.sendToLua("buttonClicked", {buttonId: "greet"});
});
NativeBridge.on("buttonResponse", function(data) {
document.getElementById("response").textContent = data.message;
});
]]
end
local function webListener( event )
if event.type == "loaded" then
injectJS()
end
end
webView:request( "index.html", system.ResourceDirectory )
webView:addEventListener( "urlRequest", webListener )
```
Here's an example HTML file that works with the above Lua and JavaScript code:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>WebView Example</title>
<style>
body { font-family: Arial, sans-serif; padding: 20px; }
button { margin: 10px 0; }
</style>
</head>
<body>
<h1>WebView Communication Example</h1>
<div id="deviceInfo"></div>
<button id="updateButton">Update Device Info</button>
<button id="greetButton">Send Greeting</button>
<p id="response"></p>
</body>
</html>
```
Now we will call window.onNativeBridgeLoaded on page loaded.
Use this feature in html:
```html
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
<p>This is a simple HTML page.</p>
</body>
<script>
window.onNativeBridgeLoaded = function() {
// NativeBridge.callNative(method, args)
// NativeBridge.sendToLua(event, data)
// NativeBridge.on(event, callback, options)
}
</script>
</html>
```
…BridgeReady.
Now we will call window.onNativeBridgeReady on page loaded.
Use this feature in html:
```html
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
<p>This is a simple HTML page.</p>
</body>
<script>
window.onNativeBridgeReady = function() {
// NativeBridge.callNative(method, args)
// NativeBridge.sendToLua(event, data)
// NativeBridge.on(event, callback, options)
}
</script>
</html>
```
