我有一个覆盖脚本，当链接如下时弹出：

<a id="b1" href="page.html">link</a>

用来。问题是我需要多个链接但不能使用相同的 ID。

这是代码：

$(function(){

$('#b1').frameWarp();

});

我尝试用 .b1 和 a.b1 替换 #b1 并使用类而不是 ID。这在第一个链接上工作正常，但任何后续点击的链接都会导致点击的第一页再次打开。我认为与覆盖脚本中已经使用的类存在冲突。

有没有办法我可以使用 onclick in 让它以同样的方式工作？

该脚本来自一个插件，但其余部分如下：

(function($){

// Private varialble deffinitions

var body = $('body'),
    win = $(window),
    popup, popupBG;

var frameCache = {};
var frameCacheDiv = $('<div class="frameCacheDiv">').appendTo('body');
var currentIframe;

// The main plugin code

$.fn.frameWarp = function(settings){

    // Supplying default settings

    settings = $.extend({
        cache: false,
        url: '',
        width:600,
        height:500,
        closeOnBackgroundClick: true,
        onMessage:function(){},
        onShow:function(){}
    }, settings);

    this.on('click',function(e){

        e.preventDefault();

        var elem = $(this),
            offset = elem.offset();

        // The center of the button
        var buttonCenter = {
            x: offset.left - win.scrollLeft() + elem.outerWidth()/2,
            y: offset.top - win.scrollTop() + elem.outerHeight()/2
        };

        // The center of the window
        var windowCenter = {
            x: win.width()/2,
            y: win.height()/2
        };

        // If no URL is specified, use the href attribute.
        // This is useful for progressively enhancing links.

        if(!settings.url && elem.attr('href')){
            settings.url = elem.attr('href');
        }

        // The dark background

        popupBG = $('<div>',{'class':'popupBG'}).appendTo(body);

        popupBG.click(function(){

            if(settings.closeOnBackgroundClick){
                hide();
            }

        }).animate({    // jQuery++ CSS3 animation
            'opacity':1
        },400);


        // The popup

        popup = $('<div>').addClass('popup').css({
            width   : 0,
            height  : 0,
            top     : buttonCenter.y,
            left    : buttonCenter.x - 35
        });

        // Append it to the page, and trigger a CSS3 animation
        popup.appendTo(body).animate({
            'width'                 : settings.width,
            'top'                   : windowCenter.y - settings.height/2,
            'left'                  : windowCenter.x - settings.width/2,
            'border-top-width'      : settings.height,
            'border-right-width'    : 0,
            'border-left-width'     : 0
        },200,function(){

            popup.addClass('loading').css({
                'width': settings.width,
                'height': settings.height
            });

            var iframe;

            // If this iframe already exists in the cache
            if(settings.cache && settings.url in frameCache){
                iframe = frameCache[settings.url].show();
            }
            else{

                iframe = $('<iframe>',{
                    'src' : settings.url,
                    'css' : {
                        'width' : settings.width,

试试这个：

<a href="javascript:this.onclick=framewrap()">link1</a>
<a href="javascript:this.onclick=framewrap()">link2</a>
<a href="javascript:this.onclick=framewrap()">link3</a>

没试过，但应该可以
