ios与html5交互 简书,IOS与H5交互(WKWebView)
先上H5代码
未设置密码/忘记密码？
function _password_jump(){
var rd_type = "password";
if(isiOSPlatform()){
var shopping_ios = { name: "view_record",type : rd_type};
window.webkit.messageHandlers.main_onItemClick.postMessage(shopping_ios);
}
}
function isiOSPlatform() {
var ua = navigator.userAgent.toLowerCase();
if (/iphone|ipad|ipod/.test(ua)) {
return true;
} else {
return false;
}
}
function payResult(str){
if(str == "123"){
window.location.href='https://www.hao123.com/';
}
}
window.payResult = function(){
window.location.href='https://www.baidu.com/';
}
继续OC代码
