我可以通过下面的代码升序排序
function getSorted(selector, attrName) {
return $($(selector).toArray().sort(function(a, b){
var aVal = parseInt(a.getAttribute(attrName)),
bVal = parseInt(b.getAttribute(attrName));
return aVal - bVal;
}));
}
var sorthtml = getSorted('.instrument', 'data-sortpopular');
$(".vddl-list").html(sorthtml);
但是无法将其降序排序,我尝试了如下所示的操作
sorthtml.toArray().reverse();
$(".vddl-list").html(sorthtml);
如评论中所问:以下是示例html
<div class="vddl-list" data-sortpopular="12">
something
</div>
<div class="vddl-list" data-sortpopular="2">
something
</div>
<div class="vddl-list" data-sortpopular="3">
something
</div>
最佳答案
您的getSorted
函数已损坏,这里有个修复程序,它将可以正常工作!
如果要升序,只需注释最后两行,否则,您将获得反向版本(降序);)
希望这可以帮助!
function getSorted(selector, attrName) {
return $(selector).toArray().sort(function(a, b){
var aVal = parseInt(a.getAttribute(attrName)),
bVal = parseInt(b.getAttribute(attrName));
return aVal - bVal;
});
}
var sorthtml = getSorted('.instrument', 'data-sortpopular');
$(".vddl-list").html(sorthtml);
sorthtml.reverse();
$(".vddl-list").html(sorthtml);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="instrument" data-sortpopular="12">
something 12
</div>
<div class="instrument" data-sortpopular="2">
something 2
</div>
<div class="instrument" data-sortpopular="3">
something 3
</div>
<div class="vddl-list"></div>
