js中通过javascriptbBridge调用客户端方法

function connectWebViewJavascriptBridge(callback) {
if (window.WebViewJavascriptBridge) {
callback(WebViewJavascriptBridge)
} else {
document.addEventListener('WebViewJavascriptBridgeReady', function() {
callback(WebViewJavascriptBridge)
}, false)
}
}
connectWebViewJavascriptBridge(function(bridge) {
bridge.init(function(message, responseCallback) {
var data = { 'Javascript Responds':'Wee!' }
responseCallback(data)
})
$("#selectButton").click( function(e) {
e.preventDefault()
bridge.callHandler('onSelect', {}, function(result) {
alert(result);
})
})
});
