$文檔準備不工作ie8

Question

我有一個小問題，我的JavaScript不工作在IE8。在Firefox，ie9和Chrome中運行良好，但不是ie8。我知道它與ie8中的文檔準備工作不同，但我無法找到答案。見下面的代碼。

// JavaScript Document 
/* Set Opacity to 0 for all list items that do not have class show 
This prevents the gallery animation from jumping around unexpectedly. 
*/ 
function clearShowClass() { 
    setTimeout(timedInterval, 1000); 
}; 

function timedInterval() { 
    $('ul.slideshow li').not('.show').css("opacity", 0); 
    clearShowClass(); 
}; 


function slideShow(speed) { 

    //Call the gallery function to run the slideshow 
    var timer = setInterval('gallery()', speed); 

    //Pause the slideshow on mouse over content 
    $('#footer, ul.slideshow').hover(

    function() { 
      clearInterval(timer); 
    }, 

    function() { 
      timer = setInterval('gallery()', speed); 
    }); 
} // End of slideshow 
/* Slideshow gallery main images */ 

function gallery() { 
    //if no IMGs have the show class, grab the first image 
    var current = ($('ul.slideshow li.show') ? $('ul.slideshow li.show') : $('#ul.slideshow li.first')); 

    //Get next image, if it reached the end of the slideshow, rotate it back to the first image 
    var next = ((current.next().length) ? ((current.next().attr('id') == 'slideshow-caption') ? $('ul.slideshow li:first') : current.next()) : $('ul.slideshow li:first')); 

    //Set the fade in effect for the next image, show class has higher z-index 
    next.css({ 
      opacity: 4.0 
    }).addClass('show').animate({ 
      opacity: 4.0 
    }, 1000); 

    // Hide the current image 
    current.animate({ 
      opacity: 0.0 
    }, 1000).removeClass('show'); 

    //if no thumbnails have the highlight class, grab the first thumbnail 
    var currentThumb = ($('#footer li.highlight') ? $('#footer li.highlight') : $('#footer li:first')); 

    var nextThumb = ($('#footer li:last').hasClass('highlight')) ? $('#footer li:nth-child(1)') : $('#footer li.highlight').next($('#footer li')); 

    nextThumb.addClass('highlight'); 
    currentThumb.removeClass('highlight'); 
}; // End of Gallery 
function thumbInt() { 
    for (i = 1; i <= $('ul.slideshow li').length; i++) { 
      $('#footer .thumbnail' + i).bind('click', { 
        iteration: i 
      }, function (event) { 
        $('ul.slideshow li').removeClass('show').css("opacity", 0).add($('ul.slideshow li:nth-child(' + event.data.iteration + ')').addClass('show').css("opacity", 0.0).animate({ 
          opacity: 1.0 
        }, 1000)); 

        $('#footer li').removeClass('highlight').add($('#footer li:nth-child(' + event.data.iteration + ')').addClass('highlight').add($('#footer li:nth-child(' + event.data.iteration + ') img'))); 
      }); 
    }; 
}; 

var prmEnd = Sys.WebForms.PageRequestManager.getInstance(); 
prmEnd.add_endRequest(function() { 

    thumbInt(); // Assign int to thumbnail list items 
    clearShowClass(); // Prevents multiple li having .show 
    $('#footer img').mouseover(

    function() { 
      $(this).animate({ 
        opacity: 3.7 
      }) 
    }); 

    $('#footer img').mouseout(

    function() { 

      $(this).animate({ 
        opacity: 0.7 
      }) 
    }); 

    //Set the opacity of all images to 0 
    $('ul.slideshow li').css({ 
      opacity: 0.0 
    }); 

    //Get the first image and display it (set it to full opacity) 
    $('ul.slideshow li:first').css({ 
      opacity: 1.0 
    }).addClass('show'); 

    //Get the first thumbnail and change css 
    $('#footer li:first').css({ 
      opacity: 1.0 
    }).addClass('highlight'); 

}); 



$(document).ready(function() { 

    slideShow(6000); 

    thumbInt(); // Assign int to thumbnail list items 
    clearShowClass(); // Prevents multiple li having .show 
    $('#footer img').mouseover(

    function() { 

      $(this).animate({ 

        opacity: 3.7 

      }) 

    }); 


    $('#footer img').mouseout(

    function() { 

      $(this).animate({ 
        opacity: 0.7 
      }) 
    }); 

}); 

此頁面的工作方式是在一個電臺用戶點擊按鈕來觸發_doPostBack並顯示一個圖片庫。問題是，當我做_dopostback文檔就緒代碼不再起作用，但這隻發生在ie8。我正在使用Sys.WebForms.PageRequestManager.getInstance（）;用於在更新面板中更新後運行的代碼。

謝謝。

Answer 1

有同樣的問題。 IE8的document.ready功能甚至沒有發出警報。 我通過將jquery版本從1.10.1更新到1.10.2解決了問題，並且還包括了推薦的遷移js。

Answer 2

我有同樣的問題。通過將腳本類型=「application/javascript」更改爲type =「text/javascript」來解決我的問題
