在IE中停止JS

Question

如何停止在IE8/9中運行以下腳本？出於某種原因，有時候這些部分會消失，有時候不會，所以我更喜歡在IE8/9中關閉它。

$(document).ready(function() { 

    /* Every time the window is scrolled ... */ 
    $(window).scroll(function(){ 

     /* Check the location of each desired element */ 
     $('.hideme').each(function(i){ 

      var bottom_of_object = $(this).position().top + $(this).outerHeight(); 
      var bottom_of_window = $(window).scrollTop() + $(window).height(); 

      /* If the object is completely visible in the window, fade it it */ 
      if(bottom_of_window > bottom_of_object){ 

       $(this).animate({'opacity':'1'},1500); 

      } 

     }); 

    }); 

});

您可以使用此功能

function IEVersion() { 
    var userAgent = navigator.userAgent.toLowerCase(); 
    var msie = userAgent.indexOf("msie "); 

    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer, return version number 
      return parseFloat((userAgent.match(/.*(?:rv|ie)[\/: ](.+?)([ \);]|$)/) || [])[1]); 

    return false; 
} 

檢測MS IE版本，您可能會發現細節上低於微軟支持網站：

，你必須使用它與你的代碼如下

function IEVersion() { 
    var userAgent = navigator.userAgent.toLowerCase(); 
    var msie = userAgent.indexOf("msie "); 

    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer, return version number 
      return parseFloat((userAgent.match(/.*(?:rv|ie)[\/: ](.+?)([ \);]|$)/) || [])[1]); 

    return false; 
} 

$(document).ready(function() { 

    /* Every time the window is scrolled ... */ 
    var ie = IEVersion(); 
    if(ie == false or (ie != 8 and ie != 9)) 
     your_code(); 

    function your_code() { 
    $(window).scroll(function(){ 

     /* Check the location of each desired element */ 
     $('.hideme').each(function(i){ 

      var bottom_of_object = $(this).position().top + $(this).outerHeight(); 
      var bottom_of_window = $(window).scrollTop() + $(window).height(); 

      /* If the object is completely visible in the window, fade it it */ 
      if(bottom_of_window > bottom_of_object){ 

       $(this).animate({'opacity':'1'},1500); 

      } 

     }); 

    }); 
    } 

});
