javascript - 图像在 safari 和 chrome 中缩放，但在 ff 和 opera 中不缩放

Question

我正在使用名为 jb gallery 3.0 的图像 slider - 使用 jQuery 运行。

它只是一个普通的图像 slider ，但它具有检测浏览器大小然后将图像缩放到浏览器大小的功能，即。如果您在 iPad 上查看，它会给您一个较小的图像，以便您仍然可以看到整个图片。

每次在 slider 中加载图像时都会调整大小，因此如果您在幻灯片之间调整窗口大小，则下次加载图像时它将被缩放...无需刷新页面。

这一切在 safari 和 chrome 中都可以正常工作，但在 firefox 和 opera (12.14) 中却不行，它只提供裁剪后的全尺寸图像...

我对这里发生的事情做了一个 js fiddle - http://jsfiddle.net/ktvvW/5/ - 尝试调整 chrome 或 safari 中“结果”面板的大小，看看会发生什么。

知道为什么这在 ff 或 opera 中不起作用吗？

干杯

在 jbgallery-3.0.js 脚本上强制执行 webkit 行为似乎可以解决这个问题。 请参阅下面的选项，我强制 webkit 为 true(忽略 userAgent)。 我已经在 FF 和 Opera 上对此进行了测试，功能符合预期，图像以与 Chrome 中相同的缩放比例显示。

$(".jbgallery").jbgallery({  
    style    : "zoom",       //"centered"|"zoom"|"original" - image style  
    menu     : "simple",         //false|"numbers"|"simple"|"slider" - menu type  
    shortcuts: [37, 39],         //[prev,next] - keyboard code shortcuts  
    slideshow: true,            //true|false - autostart slideshow  
    fade     : true,             //true|false - disable all fade effects  
    popup    : false,            //true|false - modal box & traditional popup hack to display multiple gallery (3.0 : fullscreen:false)  
    randomize: 0,                //0|1|2 - randomize first image (1) or randomize "slideshow" (2) - blackout: http://www.grayhats.org  
    caption  : false,             //true|false - show/disable internal caption system  
    autohide : false,            //true|false - auto hide menu & caption  
    clickable: false,            //true|false - "image click & go"  
    current  : 1,                //number     - set initial photo (modal "hack" - see demo. don't use "hash". jbgallery use "location.hash" only in popup mode)  
//    webkit   : (navigator.userAgent.toLowerCase().search(/webkit/) != -1),  //boolean - used for specific browser hack. if you want, you can force disable this flag & try to find crossbrowser solution  
    webkit   : true,
    ie6      : (/MSIE 6/i.test(navigator.userAgent)), //boolean - IDEM  
    ie7      : (/MSIE 7/i.test(navigator.userAgent)), //boolean - IDEM  
    labels   : {                 //labels of internal menu  
        play : "play",  
        next : "next",  
        prev : "prev",  
        stop : "stop",  
        close: "close",  
        info : "info"  
    },  
    timers   : {                 //timers   
        fade    : 1000,           //fade duration  
        interval: 3000,          //slideshow interval  
        autohide: 7000           //autohide timeout  
    },  
    delays: {                    //delays (timers) to improve usability and reduce events  
        mousemove: 200,          //used by autohide. cancel autohide timeout every XXXms.   
        resize   : 10,          //used by ie6 to reduce events handled by window.resize  
        mouseover: 800           //used by tooltip. show tooltip only if the mouse STAY over thumb for XXXms  
    },  
    close    : function(){},     //callback handled by menu's button close. see demo. example : close : function(){window.close()}  
    before   : function(){},     //callback handled BEFORE image gallery loaded  
    after    : function(ev){},   //callback(ev) handled AFTER image gallery loaded. receive the native load event.  
    load     : function(ev){},   //callback(ev) handled AFTER native image load event. receive the native load event.  
    ready    : function(el){$('.jbg-menu').hide(); $('.jbg-loading').remove(); $('.jbg-caption').remove(); $('.jbg-menu-opacity').remove();},   //callback(el) handled AFTER jbgallery render. receive the HTML element.  
    fullscreen: false,            //true|false : the most important feature of jbgallery 3.0. now jbgallery can "stay in a box" and have multiple istance in one page.  
    push      : function(o){},   //callback handled by push public method (JBGALLERY API). receive the object/string/array of objects/array of strings passed from external. useful for external menu system  
    unshift   : function(o){},   //callback handled by unshift public method (JBGALLERY API). receive the object/string/array of objects/array of strings passed from external.  
    shift     : function(){},    //callback handled by shift public method   
    pop       : function(){},    //callback handled by pop public method   
    empty     : function(){}     //callback handled by empty public method   
});
