Cordova - window.history.back() 不适用于 iOS 9 中的 HTML 后退按钮 [英] Cordova - window.history.back() not working on HTML back button in iOS 9

问题描述

在我的应用程序中，我使用 window.history.back 导航回上一个视图

In my application I am using window.history.back to navigate back to previous View

返回按钮的声明

 <div class="back_icon"  id="verification_back_icon"><a href="#" data-rel="back"  data-transition="slidedown"><img src="images/back_btn.png" width="23"/></a></div>

按钮操作:

$( "#verification_back_icon" ).on( "click", function ( e ) {
    if ( checkDirtyVacation() ) {
        e.preventDefault();
        if ( backbtnAlt == false ) {
            backbtnAlt = true;
            confirm( "All data will be lost. Do you want to continue?",
                function ( r ) {
                    if ( r ) {
                        //onBackKeyDown();
                        clearVacationvalues();
                        window.history.back();//this is not working in iOS 9
                    } else {

                    }
                    backbtnAlt = false;
                } );
        }
    }
    else {
        e.preventDefault();
        if ( $( ".vaction_location" ).hasClass( "chkSelect" ) ) {
            $( ".vaction_location" ).removeClass( "chkSelect" );
            $( ".vaction_location" ).addClass( "chkUnSelect" );
        }


        window.history.back();
    }
} );

这在 iOS 8.4 之前一直有效.在 iOS 9 中，此导航不起作用.

This worked perfectly till iOS 8.4. In iOS 9 this navigation is not working.

我使用的是 Apache Cordova 本机平台版本 3.8.0.

如果有人遇到类似问题，请给我建议.我试过 history.back 没有不能在使用 Cordova 的 iOS 上工作，但没有运气

If anyone facing the similar problem please suggest me. I have tried with history.back doesn't work on iOS using Cordova, but no luck

谢谢.

推荐答案

解决方案:

这一行解决了我的问题:

This line resolved my issue :

 history.go(0); 

我已经用 history.go(0);

现在它在 iOS 9 中运行良好

Now it is working fine for me in iOS 9

在 index.html

   <script type="text/javascript">$.mobile.hashListeningEnabled = false;</script>

在 onDeviceReady 函数中添加:

function onDeviceReady() {
    if ( device.platform === "iOS" && parseInt( device.version ) === 9 ) {
        $.mobile.hashListeningEnabled = false;
    }

    if ( !( $.mobile.hashListeningEnabled &&
        $.mobile.path.isHashValid( location.hash ) &&
        ( $( hashPage ).is( ":jqmData(role='page')" ) ||
            $.mobile.path.isPath( hash ) ||
            hash === $.mobile.dialogHashKey ) ) ) {

        // make sure to set initial popstate state if it exists
        // so that navigation back to the initial page works properly
        if ( $.event.special.navigate.isPushStateEnabled() ) {
            $.mobile.navigate.navigator.squash( path.parseLocation().href );
        }

        $.mobile.changePage( $.mobile.firstPage, {
            transition: "none",
            reverse: true,
            changeHash: false,
            fromHashChange: true
        } );
    } else {
        // trigger hashchange or navigate to squash and record the correct
        // history entry for an initial hash path
        if ( !$.event.special.navigate.isPushStateEnabled() ) {
            $window.trigger( "hashchange", [true] );
        } else {
            // TODO figure out how to simplify this interaction with the initial history entry
            // at the bottom js/navigate/navigate.js
            $.mobile.navigate.history.stack = [];
            $.mobile.navigate( $.mobile.path.isPath( location.hash ) ? location.hash : location.href );
        }
    }
}

设备操作系统版本验证(因为 history.go(0) 仅适用于 iOS 9) 在 iOS 9 版本之前 window.history.back() 工作完美

Validation for device OS version (as history.go(0) is working only with iOS 9) Prior to iOS 9 version window.history.back() working perfectly

现在添加这段代码代替 window.history.back()

if ( device.platform === "iOS" && parseInt( device.version ) === 9 ) {
    console.log( "version" + device.version );
    console.log( "iOS 9" );
    history.go( 0 );
    //write your code here                 
}
else {
    window.history.back();
}

要修复此消息无法加载网页并出现错误:CDVWebViewDelegate:当 state=1 时导航开始"在控制台中添加以下代码在 CDVWebViewDelegate.m

To fix this Message "Failed to load webpage with error: CDVWebViewDelegate: Navigation started when state=1" in console add below code in CDVWebViewDelegate.m

在 - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType

In - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType

方法注释这段代码如下所示:

Method Comment this piece of code shown below:

/*if ([_delegate respondsToSelector:@selector(webView:didFailLoadWithError:)]) {
    NSDictionary* errorDictionary = @{NSLocalizedDescriptionKey : description};
    NSError* error = [[NSError alloc] initWithDomain:@"CDVWebViewDelegate" code:1 userInfo:errorDictionary];
    [_delegate webView:webView didFailLoadWithError:error];
}*/
