目前我正在編寫某種網絡應用程序,我想隱藏iOS設備上的地址欄,最好也在Android設備上隱藏地址欄。
通常我做這與隱藏地址欄不起作用 - 需要防彈手段

window.addEventListener('load', function() { 
    setTimeout(function() { 
    window.scrollTo(0, 1); 
    }, 0); 
}); 

但由於頁面有沒有足夠的內容進行滾動,這將不是現在的工作。
現在我知道這是一個常見問題,我知道有多種解決方案,但我更喜歡小型的防彈解決方案。
其實我還是挺高興的時候,我發現這樣一個問題:http://stackoverflow.com/questions/9678194/cross-platform-method-for-removing-the-address-bar-in-a-mobile-web-app

其中該代碼被張貼:

function hideAddressBar() 
{ 
    if(!window.location.hash) 
    { 
     if(document.height < window.outerHeight) 
     { 
      document.body.style.height = (window.outerHeight + 50) + 'px'; 
     } 

     setTimeout(function(){ window.scrollTo(0, 1); }, 50); 
    } 
} 

window.addEventListener("load", function(){ if(!window.pageYOffset){ hideAddressBar(); } }); 
window.addEventListener("orientationchange", hideAddressBar); 

不幸的是,這並沒有爲我工作。我發現發生了一些情況,因爲某些以百分比設置的元素padding-top向下移動,但地址欄保持不變。

當然,我也做了谷歌搜索,並嘗試了很多我發現的片段。有些什麼都沒做,有的只是將padding-top的元素向下移動了一下。
我發現的唯一的工作代碼是這樣的:

var page = document.getElementById('page'), 
    ua = navigator.userAgent, 
    iphone = ~ua.indexOf('iPhone') || ~ua.indexOf('iPod'), 
    ipad = ~ua.indexOf('iPad'), 
    ios = iphone || ipad, 
    // Detect if this is running as a fullscreen app from the homescreen 
    fullscreen = window.navigator.standalone, 
    android = ~ua.indexOf('Android'), 
    lastWidth = 0; 

if (android) { 
    // Android's browser adds the scroll position to the innerHeight, just to 
    // make this really difficult. Thus, once we are scrolled, the 
    // page height value needs to be corrected in case the page is loaded 
    // when already scrolled down. The pageYOffset is of no use, since it always 
    // returns 0 while the address bar is displayed. 
    window.onscroll = function() { 
    page.style.height = window.innerHeight + 'px' 
    } 
} 
var setupScroll = window.onload = function() { 
    // Start out by adding the height of the location bar to the width, so that 
    // we can scroll past it 
    if (ios) { 
    // iOS reliably returns the innerWindow size for documentElement.clientHeight 
    // but window.innerHeight is sometimes the wrong value after rotating 
    // the orientation 
    var height = document.documentElement.clientHeight; 
    // Only add extra padding to the height on iphone/ipod, since the ipad 
    // browser doesn't scroll off the location bar. 
    if (iphone && !fullscreen) height += 60; 
    page.style.height = height + 'px'; 
    } else if (android) { 
    // The stock Android browser has a location bar height of 56 pixels, but 
    // this very likely could be broken in other Android browsers. 
    page.style.height = (window.innerHeight + 56) + 'px' 
    } 
    // Scroll after a timeout, since iOS will scroll to the top of the page 
    // after it fires the onload event 
    setTimeout(scrollTo, 0, 0, 1); 
}; 
(window.onresize = function() { 
    var pageWidth = page.offsetWidth; 
    // Android doesn't support orientation change, so check for when the width 
    // changes to figure out when the orientation changes 
    if (lastWidth == pageWidth) return; 
    lastWidth = pageWidth; 
    setupScroll(); 
})();

但我不是這個解決方案真的很高興,因爲我不是UA嗅探的朋友。

你有什麼建議可以嘗試使它在沒有UA嗅探的情況下工作嗎?它可能是我的HTML導致我發佈的一些腳本的問題?

不知道它是否防彈,但它可以在一堆設備上工作。如果您發現警告,請告訴我。

if (((/iphone/gi).test(navigator.userAgent) || (/ipod/gi).test(navigator.userAgent)) && 
    (!("standalone" in window.navigator) && !window.navigator.standalone)) { 
    offset = 60; 
    $('body').css('min-height', (window.innerHeight + offset) + 'px'); 
    setTimeout(function(){ window.scrollTo(0, 1); }, 1); 
} 

if ((/android/gi).test(navigator.userAgent)) { 
    offset = 56; 
    $('html').css('min-height', (window.innerHeight + offset) + 'px'); 
    setTimeout(function(){ window.scrollTo(0, 1); }, 0); 
} 
+0

嘿,感謝你的答案 - 良藥苦口,呵呵;-)不幸的是,我還沒有找到一個真的* *滿足此解決方案。目前最大的警告是iOS 7,我認爲,如果我沒有弄錯地址欄,就不可能再隱藏地址欄,這會使任何解決方案都無用。 – Sven 2013-10-18 18:02:08
