Question

这个javascript与php一起工作，当用户试图离开页面时向用户显示广告（我知道的令人讨厌的功能......不是我的选择）。

用户尝试离开后所需的事件顺序为：
1. Onbeforeunload：显示广告 - The Ad before choice
2。一个。如果他们离开：没什么
b。如果它们停留：调用adDisplayed（）在用户留下的数据库中标记。
3。如果他们点击广告，则另一个功能会标记他们点击了广告。

这适用于Chrome和IE，但在Firefox中，“2. a。”永远不会发生相反，“2. b。”无论他们是留下还是离开都会发生 onunload函数成功阻止adDisplayed（）在离开时实际执行，但在Firefox中除外。

var markSeen = 0;

function regularChatDisplay(e) {
    //This is called just before the page unloads      
    if(validNavigation == false && windowInteraction == true){   
        isDone = true;  
        window.onbeforeunload = null;
        window.pagehide = null;  

        showAd();    
        AdHasDisplayed = 1; 

        //Setting this on a timout enables us to execute this only if the user stays                                
        markSeen  = setTimeout("adDisplayed();", 800);        
        return "Wait! Want to see other offers you may be interested in? Please stay to see an additional offer.";           
    }      
} 
function noTimeout() {   
    //This prevents adDisplayed() if the user leaves instead of staying when presented with the dialogue box 
    clearTimeout(markSeen);
}            

function setOnBeforeUnloadEvent() {                       
    if (!isDone) {                                    
        window.onbeforeunload = regularChatDisplay;    
        window.pagehide = regularChatDisplay;    
        window.onunload = noTimeout;
    }      
}
function adDisplayed(){
    //Placing something here will cause it to be executed after the user chooses to stay on the page after having been prompted  
    $("#seenSpan").load('pages/adSeen.php');     
}                         
setOnBeforeUnloadEvent();

我已经在这方面工作了一段时间，我一直都在寻找答案，所以任何帮助都会很棒。谢谢！

我找到了解决方法。它并不完美，但它确实有效：

function regularChatDisplay(e) {    
    //This is called just before the page unloads      
    if(validNavigation == false && windowInteraction == true){   
        isDone = true;  
        window.onbeforeunload = null;
        window.pagehide = null;  

        showAd();    
        AdHasDisplayed = 1; 

        //Setting this on a timout enables us to execute this only if the user stays
        if(browserType != "Firefox"){
            markSeen  = setTimeout("adDisplayed();", 800);  
        }
        else{  
            window.onbeforeunload = adDisplayed;    
        }                                                     
        return "Wait! Want to see other offers you may be interested in? Please stay to see an additional offer.";           
    }      
}

缺点是它在你选择停留的时候并没有真正开火，但是如果你离开它就会开火，它仍然有效。

我会离开这个，以防它对其他人有帮助。

Onbeforeload之后的Firefox Onunload
