Sort element by numerical value of data attribute
提问by JayDee
I have multiple elements with the attribute: data-percentage, is there a way of sorting the elements into ascending order with the lowest value first?

Use Array.sort:
使用Array.sort:
var $wrapper = $('.testWrapper');
$wrapper.find('.test').sort(function(a, b) {
return +a.dataset.percentage - +b.dataset.percentage;
})
.appendTo($wrapper);
Here's the fiddle: http://jsfiddle.net/UdvDD/

If you're using IE < 10, you can't use the datasetproperty. Use getAttributeinstead:
如果您使用的是 IE < 10,则不能使用该dataset属性。使用getAttribute来代替:
var $wrapper = $('.testWrapper');
$wrapper.find('.test').sort(function(a, b) {
return +a.getAttribute('data-percentage') - +b.getAttribute('data-percentage');
})
.appendTo($wrapper);

$('.testWrapper').find('.test').sort(function (a, b) {
return $(a).attr('data-percentage') - $(b).attr('data-percentage');
})
.appendTo('.testWrapper');

For some reason, on Firefox 64.0.2, none of the answers worked for me. This is what worked in the end, a mixture of Joseph Silber and Jeaf Gilbert's answers:
出于某种原因,在 Firefox 64.0.2 上,没有一个答案对我有用。这就是最终奏效的方法,结合了 Joseph Silber 和 Jeaf Gilbert 的答案:
var $wrapper = $('.testWrapper');
$wrapper.find('.test').sort(function(a, b) {
return +$(a).data('percentage') - +$(b).data('percentage');
})
.appendTo($wrapper);

I think that the Tinysort Jquery plugin should be an option, you can get it i here: http://tinysort.sjeiti.com/
我认为 Tinysort Jquery 插件应该是一个选项,你可以在这里得到它:http://tinysort.sjeiti.com/
I did not tried it but the code should look like this:
我没有尝试过,但代码应该是这样的:
$("#test > div").tsort("",{attr:"data-percentage"});
hope this will help
希望这会有所帮助

A more robust option, this function can allow you to sort elements based on multiple options.
更强大的选项,此功能可以让您根据多个选项对元素进行排序。

// This calls the function
DOYPSort('#wrapper', '.element', value, order);
// Parameters must be strings
// Order of must be either 'H' (Highest) or 'L' (Lowest)
function DOYPSort(wrapper, elementtosort, AttrToSort, orderof) {
$(wrapper).find(elementtosort).sort(function (a, b) {
if (orderof === 'H') {
return +b.getAttribute(AttrToSort) - +a.getAttribute(AttrToSort);
}
if (orderof === 'L') {
return +a.getAttribute(AttrToSort) - +b.getAttribute(AttrToSort);
}
}).appendTo(wrapper);
}
