在IE8中不工作window.onload [英] Does not work window.onload in IE8

问题描述

我有一个非常简单的图像切换器，用于手动图像切换器和传送带。在IE 8中，它很奇怪。在轮播场景中，图像只切换一次，然后死亡。但是（！）当我实现Firebug Lite并试图追踪 - 它运行良好，只有在上使用了萤火虫...我尝试了一些技巧，我发现，但这完全没有目的。我不知道是什么导致了这种行为。如何解决它？

js

 函数toSlide（wrapper，选项）{
 var active = $（'＃'+ wrapper +'div.active'）; 
 var slide; 
 var direction; 
 
 if（active.length === 0）{
 active = $（'＃'+ wrapper +'div：last'）; 
} 
 
 if（options === null）{
 options = {}; 
 options.reverse = false; 
 options.animate = false; 
} else {
 options.reverse = options.reverse === null？ false：options.reverse; 
 options.animate = options.animate === null？ false：options.animate; 
} 
 
 direction = options.reverse === true？ active.prev（）：active.next（）; 
 
 slide = direction.length？方向：$（'＃'+ wrapper +'div：first'）; 
 
 if（options.animate === true）{
 active.addClass（'last-active'）; 
 
 slide.addClass（'active'）
 .css（{opacity：0.0}）
 .animate（{opacity：1.0}，1000，function（）{
 active.removeClass（'active last-active'）; 
}）; 
} else {
 slide.addClass（'active'）; 
 active.removeClass（'active'）; 
 
 
 
函数startSlideShow（）{
 setInterval（function（）{toSlide（'slideshow'，{'animate'：true}）;}， 5000）; 
}; 
 
 window.onload = function（）{
 if（document.location.pathname =='/'）{startSlideShow（）;}; 
};

解决方案

原因是IE8中的非函数window.onload 。我做了正确的伎俩，但犯了一个愚蠢的错误。所以我解决了这个问题：

是

 <！ -  -  [如果IE 8]> 
< script defer src =ie_onload.js>< / script> 
<！[endif]  - > 
  

现在是

 <！ -  [if IE 8]> 
< script defer src ={{MEDIA_URL}} js / ie_onload.js>< / script> 
<！[endif]  - > 
  

in ie_onload.js

  document.body.onload = function（）{
 imageViewer（）; 
 //和其他函数
}; 
  

I have a pretty simple image switcher, which I use for manual images switcher and for carousel. In IE 8 it works strange. In carousel scenario image switches just once, thereafter it's dies. But (!) when I implemented Firebug Lite and try to trace - it's works well, only with firebug on... I tried some tricks, I found, but it's all to no purpose. I have no idea what caused this kind of behavior. How to fix it?

js

function toSlide(wrapper, options){
    var active = $('#' + wrapper + ' div.active');
    var slide;
    var direction;

    if (active.length === 0){
        active = $('#' + wrapper + ' div:last');
    }

    if (options === null) {
        options = {};
        options.reverse = false;
        options.animate = false;
    } else {
        options.reverse = options.reverse === null ? false : options.reverse;
        options.animate = options.animate === null ? false : options.animate;
    }

    direction = options.reverse === true ? active.prev() : active.next();

    slide = direction.length ? direction : $('#' + wrapper + ' div:first');

    if (options.animate === true){
        active.addClass('last-active');

        slide.addClass('active')
            .css({opacity:0.0})
            .animate({opacity:1.0}, 1000, function() {            
                active.removeClass('active last-active');
        });
    } else {        
        slide.addClass('active');
        active.removeClass('active');
    }
}

function startSlideShow() {
    setInterval(function(){ toSlide('slideshow', {'animate': true}); }, 5000);
};

window.onload = function() {  
    if (document.location.pathname == '/'){startSlideShow();};
};

<script src="{{ MEDIA_URL }}js/plugins.js"></script>
<script src="{{ MEDIA_URL }}js/script.js"></script>
<!-- end concatenated and minified scripts-->

解决方案

The cause was non-functional window.onload in IE8. I did right trick but made stupid mistake. So, I fixed it:

was

<!--[if IE 8 ]>
    <script defer src="ie_onload.js"></script>
<![endif]-->

is now

<!--[if IE 8 ]>  
    <script defer src="{{ MEDIA_URL }}js/ie_onload.js"></script>
<![endif]-->

in ie_onload.js

document.body.onload = function() {
    imageViewer();
    // and other functions
};
