【问题描述】：
所以让我告诉你我在做什么。这是我正在做的一些作业，现在已经卡住了。我正在创建一个页面，您可以在其中从一堆不同的复选框中进行选择。根据复选框，您可以单击我已编程的“显示资源”按钮以打开一个新窗口，其中包含相应的复选框以显示它们的值，它们的值也是这些特定资源的 URL。听起来很容易对吧？这是事物的基本结构。
//this is the main function that is making an array of the checked check boxes and displying them on the new window, problem is I am only able to set the href attibute to only the first array item...
$(function() {
$(":checkbox").change(function() {
var arr = $(":checkbox:checked").map(function() { return $(this).val(); }).get();
$("#messagepop").html('<a id="resourceLink">' + arr.join('</a><br><a id="resourceLink">') + '</a>');
for (var i = 0; i < arr.length; i++){
$("#resourceLink").attr('href', arr[i]);
}
});
});
//these are functions for the new window
function deselect(e) {
$('.pop').slideFadeToggle(function() {
e.removeClass('selected');
});
}
$(function() {
$('#contact').on('click', function() {
if($(this).hasClass('selected')) {
deselect($(this));
} else {
$(this).addClass('selected');
$('.pop').slideFadeToggle();
}
return false;
});
$('.close').on('click', function() {
deselect($('#contact'));
return false;
});
});
$.fn.slideFadeToggle = function(easing, callback) {
return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};.messagepop {
background-color:#FFFFFF;
border:1px solid #999999;
cursor:default;
display:none;
margin-top: 15px;
position:absolute;
text-align:left;
width:394px;
z-index:50;
padding: 25px 25px 20px;
}
label {
display: block;
margin-bottom: 3px;
padding-left: 15px;
text-indent: -15px;
}
.messagepop p, .messagepop.div {
border-bottom: 1px solid #EFEFEF;
margin: 8px 0;
padding-bottom: 8px;

<div class="messagepop pop">
<p><a class="close" href="/">Close</a></p>
<div id="messagepop" >
</div>
</div>
<a href="/contact" id="contact">Show Resources</a>
</div>所以我遇到的问题是我无法在新的 div 窗口中显示的新 <a> 标记上正确设置 href 属性。所有这一切的关键是我必须用选中的复选框创建一个数组，并让它们链接到相应的资源。
所以真正的问题是，我错过了什么？我可以看到该数组具有正确的元素链接，那么为什么它们没有出现在其余显示的元素上。希望这是有道理的，如果我在这里向您展示的内容令人困惑或需要澄清，请告诉我，谢谢！
