Click the return button to close the current page and window in WeChat, Alipay, and Baidu Wallet

Recently, I am using WeChat, Alipay, and Baidu Wallet to implement web payment. If the payment is successful, the page will be automatically closed. If the payment fails, an error message will be displayed. When on the error page, click Return

or the Android physical button to go back, the page will be closed.

In WeChat, Alipay, and Baidu Wallet, they encapsulate page closing. The traditional window.close() is invalid, and their js code must be used to close it. The following are three ways to close mobile apps

:

WeixinJSBridge.call('closeWindow');//微信  
 AlipayJSBridge.call('closeWebview');  //支付宝  
 BLightApp.closeWindow();//百度钱包

Determine which browser it is by the browser header:

var ua = navigator.userAgent.toLowerCase();    
f(ua.match(/MicroMessenger/i)=="micromessenger") {    
      alert("微信客户端");  
} else if(ua.indexOf("alipay")!=-1){    
 alert("支付宝客户端");   
}else if(ua.indexOf("baidu")!=-1){    
 alert("百度客户端");   
}

For return, previous page, and back Monitor and put the current page address in the history:

$(function(){  
            pushHistory();  
            window.addEventListener("popstate", function(e) {  
                  
        }, false);  
            function pushHistory() {  
                var state = {  
                    title: "title",  
                    url: "#"  
                };  
                window.history.pushState(state, "title", "#");  
            }  
});

The complete code for the entire implementation:

$(function(){  
            pushHistory();  
            window.addEventListener("popstate", function(e) {  
                pushHistory();  
                var ua = navigator.userAgent.toLowerCase();    
                if(ua.match(/MicroMessenger/i)=="micromessenger") {    
                     WeixinJSBridge.call('closeWindow');  
                } else if(ua.indexOf("alipay")!=-1){    
                     AlipayJSBridge.call('closeWebview');    
                }else if(ua.indexOf("baidu")!=-1){    
                    BLightApp.closeWindow();  
                }  
                else{  
                    window.close();  
                }  
        }, false);  
            function pushHistory() {  
                var state = {  
                    title: "title",  
                    url: "#"  
                };  
                window.history.pushState(state, "title", "#");  
            }  
        });
