# JsBridge
-----
Inspired and modified from [this](https://github.com/jacin1/JsBridge) and WeChat jsBridge file, with some bug fixes and feature enhancements.
This project makes a bridge between Java and JavaScript.
It provides a safe and convenient way to call Java code from JavaScript and call JavaScript code from Java.
## How JsBridge Works
## Demo
## Usage
## JitPack.io
I strongly recommend [JitPack.io](https://jitpack.io)
```groovy
repositories {
// ...
maven { url "https://jitpack.io" }
}
dependencies {
compile 'com.github.lzyzsd:jsbridge:1.0.4'
}
```
## Use it in Java
Add `com.github.lzyzsd.jsbridge.BridgeWebView` to your layout, it is inherited from WebView.
### Register a Java handler function so that JavaScript can call
```java
webView.registerHandler("submitFromWeb", new BridgeHandler() {
@Override
public void handler(String data, CallBackFunction function) {
Log.i(TAG, "handler = submitFromWeb, data from web = " + data);
function.onCallBack("submitFromWeb exe, response data from Java");
}
});
```
JavaScript can call this Java handler method "submitFromWeb" through:
```javascript
WebViewJavascriptBridge.callHandler(
'submitFromWeb'
, {'param': str1}
, function(responseData) {
document.getElementById("show").innerHTML = "send get responseData from java, data = " + responseData
}
);
```
You can set a default handler in Java, so that JavaScript can send messages to Java without an assigned handlerName
```java
webView.setDefaultHandler(new DefaultHandler());
```
```javascript
window.WebViewJavascriptBridge.doSend(
data
, function(responseData) {
document.getElementById("show").innerHTML = "responseData from java, data = " + responseData
}
);
```
### Register a JavaScript handler function so that Java can call
```javascript
WebViewJavascriptBridge.registerHandler("functionInJs", function(data, responseCallback) {
document.getElementById("show").innerHTML = ("data from Java: = " + data);
var responseData = "Javascript Says Right back aka!";
responseCallback(responseData);
});
```
Java can call this JavaScript handler function "functionInJs" through:
```java
webView.callHandler("functionInJs", new Gson().toJson(user), new CallBackFunction() {
@Override
public void onCallBack(String data) {
}
});
```
You can also define a default handler using the init method, so that Java can send messages to JavaScript without an assigned handlerName
For example:
```javascript
window.WebViewJavascriptBridge.init(function(message, responseCallback) {
console.log('JS got a message', message);
var data = {
'Javascript Responds': 'Wee!'
};
console.log('JS responding with', data);
responseCallback(data);
});
```
```java
webView.send("hello");
```
will print 'JS got a message hello' and 'JS responding with' in webview console.
### Persistent Callbacks (New Feature)
By default, callbacks are deleted after first use. However, you can now use persistent callbacks that can be reused multiple times:
#### Java Side
```java
// Use persistent callback that won't be deleted after first use
webView.callHandlerPersistent("functionInJs", data, new OnBridgeCallback() {
@Override
public void onCallBack(String data) {
// This callback can be called multiple times
Log.d(TAG, "Persistent callback called: " + data);
}
});
```
#### JavaScript Side
```javascript
// Use persistent callback
WebViewJavascriptBridge.callHandlerPersistent("javaHandler", data, function(response) {
// This callback can be reused multiple times
console.log("Persistent callback response: " + response);
});
// Register and manually manage persistent callbacks
var callbackId = "my_persistent_callback";
WebViewJavascriptBridge.registerPersistentCallback(callbackId, function(data) {
console.log("Persistent callback called: " + data);
});
// Remove persistent callback when no longer needed
WebViewJavascriptBridge.removePersistentCallback(callbackId);
```
This feature is useful when you need to maintain a long-term communication channel between Java and JavaScript, such as for real-time updates or event notifications.
### Switch to CustomWebView
* activity_main.xml
```xml
<com.github.lzyzsd.jsbridge.example.CustomWebView
android:id="@+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</com.github.lzyzsd.jsbridge.example.CustomWebView>
```
* MainActivity.java
Change BridgeWebView class to CustomWebView:
```java
CustomWebView webView = (CustomWebView) findViewById(R.id.webView);
```
## Notice
This library will inject a WebViewJavascriptBridge Object to the window object.
You can listen to the `WebViewJavascriptBridgeReady` event to ensure `window.WebViewJavascriptBridge` exists, as the below code shows:
```javascript
if (window.WebViewJavascriptBridge) {
//do your work here
} else {
document.addEventListener(
'WebViewJavascriptBridgeReady'
, function() {
//do your work here
},
false
);
}
```
Or put all JsBridge function call into `window.WVJBCallbacks` array if `window.WebViewJavascriptBridge` is undefined, this task queue will be flushed when `WebViewJavascriptBridgeReady` event triggered.
Copy and paste setupWebViewJavascriptBridge into your JS:
```javascript
function setupWebViewJavascriptBridge(callback) {
if (window.WebViewJavascriptBridge) {
return callback(WebViewJavascriptBridge);
}
if (window.WVJBCallbacks) {
return window.WVJBCallbacks.push(callback);
}
window.WVJBCallbacks = [callback];
}
```
Call `setupWebViewJavascriptBridge` and then use the bridge to register handlers or call Java handlers:
```javascript
setupWebViewJavascriptBridge(function(bridge) {
bridge.registerHandler('JS Echo', function(data, responseCallback) {
console.log("JS Echo called with:", data);
responseCallback(data);
});
bridge.callHandler('ObjC Echo', {'key':'value'}, function(responseData) {
console.log("JS received response:", responseData);
});
});
```
It's the same as [WebViewJavascriptBridge](https://github.com/marcuswestin/WebViewJavascriptBridge), which makes it easier for you to define the same behavior across different platforms between Android and iOS, while writing concise code.
