IOS javascript 与 Swift 代码交互

原生代码与 JS 的相互交互

原生代码调用 js handler

• html中或业务 js 中 添加 js handler

ZHWVBridge.Core.registerJsHandler(
          "Device.updateAppVersion",
          function (version) {
            document.getElementById("native-version-container").textContent = version;
            return "js get version: " + version;
          });

ZHWVBridge.Core.registerJsHandler(handlerName, callback)

• 原生代码调用 js handler

bridge.callJsHandler(
            "Device.updateAppVersion",
            args: ["1.2"],
            callback: { (data:AnyObject?) in
                // here data should be "js get version: 1.2"
                ...
        })

ZHWVBridge.Core.callNativeHandler(handlerName, 传递给原生handler的参数数组, 成功回调, 失败回调)

Js 调用原生 handler

• 原生代码中, bridge 注册 native handler

bridge.registerHandler("Image.updatePlaceHolder") { (args:[AnyObject]) -> (Bool, [AnyObject]?) in
            return (true, ["place_holder.png"])
        }

ZHWVBridge.Core.registerJsHandler(handlerName, callback)

• js 调用原生 handler

ZHWVBridge.Core.callNativeHandler(
            "Image.updatePlaceHolder",
            [],
            function(placeHolder) {
              var items = document.getElementsByTagName('img');
              for (var i = 0, count = items.length; i < count; ++i) {
                var item = items[i];
                if (item.src.toLocaleLowerCase() == "file:///default_cover") {
                  item.src = placeHolder;
                }
              }
            });

ZHWVBridge.Core.callNativeHandler(handlerName, 传递给原生handler的参数数组, 成功回调, 失败回调)
