WebViewJavascriptBridge的用法
- HTML端设置
先申明交互（// < !--申明交互 -->）
function setupWebViewJavascriptBridge(callback) {
if (window.WebViewJavascriptBridge) { return callback(WebViewJavascriptBridge); }
if (window.WVJBCallbacks) { return window.WVJBCallbacks.push(callback); }
window.WVJBCallbacks = [callback];
var WVJBIframe = document.createElement('iframe');
WVJBIframe.style.display = 'none';
WVJBIframe.src = 'wvjbscheme://__BRIDGE_LOADED__';
document.documentElement.appendChild(WVJBIframe);
setTimeout(function () { document.documentElement.removeChild(WVJBIframe) }, 0)
}
Native给JS传值（// < !--处理交互 方法名要和ios内定义的对应-- >）
setupWebViewJavascriptBridge(function (bridge) {
// <!--接收swift传过来的值 -->
bridge.registerHandler('swiftToJs', function (data, responseCallback) {
var res = JSON.parse(data);
vm.msg=res
// 接收到swift传的值后再回调给swift、可不写
responseCallback('js执行过了');
})
})
JS给Native传值（// < !--处理交互 方法名要和ios内定义的对应-- >）
WebViewJavascriptBridge.callHandler('jsToSwift', this.msg.myAnswer, function (response) {
// 处理swift过来的回调
// alert('swift传回的回调：'+response)
})
- iOS端设置
先初始化
let bridge = WKWebViewJavascriptBridge(for: self.webView)
WKWebViewJavascriptBridge.enableLogging()
bridge?.setWebViewDelegate(self)
在ViewDidLoad中注册交互方法（接收js传值）
self.webViewBridge.registerHandler("jsToSwift") { [weak self] (data, responseCallback) in
let dataArray = data as? NSArray
self?.setMyAnswer(answers: dataArray as! [Int])
}
传值给js
self.webViewBridge.callHandler("swiftToJs", data: jsonStr, responseCallback: { (responseData) in
YTLog(responseData)
})
dsBridge的用法
- HTML端设置
先通过cdn引入
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<link rel="stylesheet" href="{% static 'api/css/style.css' %}">
<script src="https://cdn.jsdelivr.net/npm/dsbridge/dist/dsbridge.js"> //</script>
<title>刷题APP</title>
</head>
接收Native传值
bridge.register('courseDetailToJs', function (data) {
let _data = JSON.parse(data)
var list = that.moneyList
list = list.concat(_data["data"])
that.moneyList = that.objInArray(list)
{#responseCallback('js执行过了');#}
})
给Native传值
bridge.call("courseDetailToNative")
- iOS端设置
先初始化（注意：这里的object可以是self也可以是新建的JsApi类，但接收传值方法需能在对应的类中找到）
let webView: DWKWebView = DWKWebView()
webView.addJavascriptObject(self, namespace: nil)
接收js传值
/// Js调用Native 不管h5那边有没有传值, (_ arg: String?)都必须写, 否则找不到该方法
@objc func courseDetailToNative(_ arg: String?) {
ExamCouponView.showCourseCouponView(courseId: _detailModel.uuid, obtainCoupon: { [weak self] (couponArray) in
self?.courseDetailToJs(data: couponArray)
})
}
传值给js
/// Native调用Js
fileprivate func courseDetailToJs(data: [Any]) {
let dataDic = ["data": data]
// js那边需要的参数格式: {data: [{discount: 33300, text: "原价立减"}, {discount: 27300, text: "折上立减"}]}
webView?.callHandler("courseDetailToJs", arguments: [dataDic.formatJSON() as Any])
}
