jquery动画背景位置firefox

我得到这个背景图片滑块的东西在chrome和safari工作,但它没有做任何事情在firefox.任何帮助？

$(function(){
    var image= ".main-content";
    var button_left= "#button_left";
    var button_right= "#button_right";
    var animation= "eaSEOutQuint";
    var time= 800;
    var jump= 800;
    var action= 0;

    $(button_left).click(function(){
        right();
    });
    $(button_right).click(function(){
        left();
    });
    $(document).keydown(function(event){
        if(event.keyCode == '37'){
            right();
        }
    });
    $(document).keydown(function(event){
        if(event.keyCode == '39'){
            left();
        }
    });
    function left(){
        if(action == 0){
            action= 1;
            $(image).animate({backgroundPositionX: '-='+jump+'px'},{duration: time,easing: animation});
            setTimeout(anim,time);
        }

    }
    function right(){
        if(action == 0){
            action= 1;
            $(image).animate({backgroundPositionX: '+='+jump+'px'},time);
        }
    }
    function anim(){
        action= 0;
    }
});

我也试过这个,但也没有做

$(image).animate({backgroundPosition: '500px 0px'},800);

解决方法

这里试试这个背景动画,

(function($) {
    if(!document.defaultview || !document.defaultview.getComputedStyle){
        var oldCurCSS = jQuery.curCSS;
        jQuery.curCSS = function(elem,name,force){
            if(name === 'background-position'){
                name = 'backgroundPosition';
            }
            if(name !== 'backgroundPosition' || !elem.currentStyle || elem.currentStyle[ name ]){
                return oldCurCSS.apply(this,arguments);
            }
            var style = elem.style;
            if ( !force && style && style[ name ] ){
                return style[ name ];
            }
            return oldCurCSS(elem,'backgroundPositionX',force) +' '+ oldCurCSS(elem,'backgroundPositionY',force);
        };
    }

    var oldAnim = $.fn.animate;
    $.fn.animate = function(prop){
        if('background-position' in prop){
            prop.backgroundPosition = prop['background-position'];
            delete prop['background-position'];
        }
        if('backgroundPosition' in prop){
            prop.backgroundPosition = '('+ prop.backgroundPosition;
        }
        return oldAnim.apply(this,arguments);
    };

    function toArray(strg){
        strg = strg.replace(/left|top/g,'0px');
        strg = strg.replace(/right|bottom/g,'100%');
        strg = strg.replace(/([0-9\.]+)(\s|\)|$)/g,"$1px$2");
        var res = strg.match(/(-?[0-9\.]+)(px|\%|em|pt)\s(-?[0-9\.]+)(px|\%|em|pt)/);
        return [parseFloat(res[1],10),res[2],parseFloat(res[3],res[4]];
    }

    $.fx.step. backgroundPosition = function(fx) {
        if (!fx.bgPosReady) {
            var start = $.curCSS(fx.elem,'backgroundPosition');

            if(!start){//FF2 no inline-style fallback
                start = '0px 0px';
            }

            start = toArray(start);

            fx.start = [start[0],start[2]];

            var end = toArray(fx.options.curAnim.backgroundPosition);
            fx.end = [end[0],end[2]];

            fx.unit = [end[1],end[3]];
            fx.bgPosReady = true;
        }
        //return;
        var NowPosX = [];
        NowPosX[0] = ((fx.end[0] - fx.start[0]) * fx.pos) + fx.start[0] + fx.unit[0];
        NowPosX[1] = ((fx.end[1] - fx.start[1]) * fx.pos) + fx.start[1] + fx.unit[1];           
        fx.elem.style.backgroundPosition = NowPosX[0]+' '+NowPosX[1];

    };
})(jQuery);

像这样调用它,

$(this).animate({backgroundPosition: '0 0'})
