Swift版本WebViewJavascriptBridge—SwiftWebViewBridge
For Swift
Generate a bridge with associated webView and default handler to deal with messages from js
public class func bridge(webView: UIWebView, defaultHandler handler: SWVBHandler?) -> SwiftWebViewBridge
Generate a bridge with associated webView and default handler to deal with messages from js without specifying designated handler
self.bridge = SwiftWebViewBridge.bridge(webView, defaultHandler: { data, responseCallback in
print("Swift received message from JS: \(data)")
// Actually, this responseCallback could be an empty closure when javascript has no callback, saving you from unwarping an optional parameter = )
responseCallback("Swift already got your msg, thanks")
})
Register a handler for JavaScript calling
self.bridge.registerHandlerForJS(handlerName: "printReceivedParmas", handler: { [unowned self] jsonData, responseCallback in
// if you used self in any bridge handler/callback closure, remember to declare weak or unowned self, preventing from retaining cycle!
// Because VC owned bridge, brige owned this closure, and this cloure captured self!
self.printReceivedParmas(jsonData)
responseCallback(["msg": "Swift has already finished its handler", "returnValue": [1, 2, 3]])
})
调用js方法
private func printReceivedParmas(data: AnyObject) {
print("Swift recieved data passed from JS: \(data)")
}
Sent data to JS simply
self.bridge.sendDataToJS(["msg": "Hello JavaScript, My name is 小明", "gift": ["100CNY", "1000CNY", "10000CNY"]])
