Jquery插件不适用于多个元素

Question

提前感谢您的帮助。我对jquery和插件整体比较陌生。我做了一些研究，并且至少在3周内一直在努力使用这个插件。

问题是我试图让多个元素与一个插件一起工作 插件代码如下

    ;(function($){
$.fn.zoom = function(options){
    //
    var _option = {
        align: "left",              // 
        thumb_image_width: 300,     // 
        thumb_image_height: 400,    // 
        source_image_width: 900,    // 
        source_image_height: 1200,  // 
        zoom_area_width: 600,       // 
        zoom_area_height: "justify",// 
        zoom_area_distance: 10,     // 
        zoom_easing: true,          //
        click_to_zoom: false,
        zoom_element: "auto",
        show_descriptions: true,
        description_location: "bottom",
        description_opacity: 0.7,
        small_thumbs: 3,            //
        smallthumb_inactive_opacity: 0.4,   // 
        smallthumb_hide_single: true,       // 
        smallthumb_select_on_hover: false,
        smallthumbs_position: "bottom",     //
        show_icon: true,
        hide_cursor: false,         // 
        speed: 600,                 // 
        autoplay: true,             // 
        autoplay_interval: 6000,    // 
        keyboard: true,
        right_to_left: false,
    }

            $bzoom_magnifier.find('div').css({width:_option.thumb_image_width*scalex, height:_option.thumb_image_height*scaley});
        }

        // 大图

            if(xpos < _option.thumb_image_width/2){
                magx = xpos > magwidth/2 ? xpos-magwidth/2 : 0;
            }else{
                magx = xpos+magwidth/2 > _option.thumb_image_width ? _option.thumb_image_width-magwidth : xpos-magwidth/2;
            }
            if(ypos < _option.thumb_image_height/2){
                magy = ypos > magheight/2 ? ypos-magheight/2 : 0;
            }else{
                magy = ypos+magheight/2 > _option.thumb_image_height ? _option.thumb_image_height-magheight : ypos-magheight/2;

            $bzoom_magnifier.css({'left':magx, 'top':magy});
            $bzoom_magnifier_img.css({'left':-magx, 'top': -magy});

            $bzoom_zoom_img.css({'left': -bigposx, 'top': -bigposy});
        }).mouseenter(function(event){
            autoPlay.stop();

            $bzoom_zoom_img.attr("src", $(this).find('.bzoom_big_image').attr('src'));
            $bzoom_zoom_area.css({"background-image":"none"}).stop().fadeIn(400);

            $ul.find('.bzoom_thumb_active').stop().animate({'opacity':0.5}, _option.speed*0.7);
            $bzoom_magnifier.stop().animate({'opacity':1}, _option.speed*0.7).show();
        }).mouseleave(function(event){
            $bzoom_zoom_area.stop().fadeOut(400);
            $ul.find('.bzoom_thumb_active').stop().animate({'opacity':1}, _option.speed*0.7);
            $bzoom_magnifier.stop().animate({'opacity':0}, _option.speed*0.7, function(){
                $(this).hide();
            });

            autoPlay.start();
        })
    }
}
    })(jQuery);

要使用插件，我明白我必须像这样触发它

$("#bzoom").zoom({
zoom_area_width: 400,
autoplay_interval :7000,
small_thumbs : 4,
autoplay : true});

但我想要做的是使用多个元素，这样我可以有两个不同的元素显示这样的图像

$("#bzoom, #bzoom2").zoom({
zoom_area_width: 400,
autoplay_interval :7000,
small_thumbs : 4,
autoplay : true});

这不起作用。它只适用于一个元素而不是两个元素。我不知道该怎么做。

会发生什么，每当我包含第二个元素时，第一个元素也会停止工作。好像在某处发生了冲突。

我的HTML是这样的

    <div class="bzoom_wrap" style="margin-left:60px">
    <ul id="bzoom"> 
        <li>
            <img class="bzoom_thumb_image" src="../images/500_thumb1.jpg" title="first img" />
            <img class="bzoom_big_image" src="../images/1000_big1.jpg"/>
        </li>
        <li>
    </ul>
</div>


            <div class="bzoom_wrap" style="margin-left:60px">
    <ul id="bzoom2"> 
        <li>
            <img class="bzoom_thumb_image2" src="../images/500_thumb1.jpg" title="first img" />
            <img class="bzoom_big_image2" src="../images/1000_big1.jpg"/>
        </li>
        <li>
    </ul>
</div>

非常感谢任何帮助。

Answer 1

您可以在插件中使用each循环：

$.fn.zoom = function(options){
    $(this).each(function(eachElement){
         //code here
    });
}

Answer 2

尝试each循环

<强> JS：

$("[id^=bzoo]").each(function() {
        $(this).zoom({
            zoom_area_width: 400,
            autoplay_interval: 7000,
            small_thumbs: 4,
            autoplay: true
        });
});
