默认排序
价格（低-高）
价格（高-低）
{properties.all%中的项的%s}
{%endfor%}

这些值是从后端动态生成的。

您可以使用Javascript（对DOM元素重新排序）或从服务器获得的响应来实现这一点

JS:

下面的代码完全符合我的要求

$(document).on("change", ".price-sorting", function() {

var sortingMethod = $(this).val();

if(sortingMethod == 'l2h')
{
    sortProductsPriceAscending();
}
else if(sortingMethod == 'h2l')
{
    sortProductsPriceDescending();
}

});
function sortProductsPriceAscending()
{
    var products = $('.product');
    products.sort(function(a, b){
    return $(a).data("price") - $(b).data("price")});
    $(".products-grid").html(products);

}

function sortProductsPriceDescending()
{
    var products = $('.product');
    products.sort(function(a, b){ return $(b).data("price") - $(a).data("price")});
    $(".products-grid").html(products);

}
