嗯,标题说明了一切。我正在做的是创建一个特色产品模块。使用JSON填充下拉列表的大小,我使用把手来渲染html。我无法控制JSON文件。我尝试按选项标签中的实际文本对选项值进行排序,但我意识到之后选项值是错误的。所以现在我试图通过它们的值属性对选项进行排序,但还没有想出来。我想做这样的事情:
var selectList = $('#featuredSelectField option');
var newList = [];
var theNewNew = [];
for(var i=0; i<selectList.length; i++){
newList[i]=(selectList[i].value);
}
newList.sort();
for(var i=0; i<newList.length; i++){
theNewNew[i] = $('#featuredSelectField option[value="'+newList[i]+'"]');
selectList[i] = theNewNew[i];
}
这是html:
<select id="featuredSelectField" name="addid7617843" size="1">
<option value="" data-value="">Select an option</option>

var selectList = $('#featuredSelectField option');
selectList.sort(function(a,b){
a = a.value;
b = b.value;
return a-b;
});
$('#featuredSelectField').html(selectList);

$(function() {
// choose target dropdown
var select = $('select');
select.html(select.find('option').sort(function(x, y) {
// to change to descending order switch "<" for ">"
return $(x).text() > $(y).text() ? 1 : -1;
}));
// select default item after sorting (first item)
// $('select').get(0).selectedIndex = 0;
});

const sort = (arr, p, o = "asc") => arr.sort((a, b) => {
if (o !== "asc")[a, b] = [b, a];
const isNum = typeof b[p] === "number";
return (isNum ? Number(a[p]) - b[p] : String(a[p]).localeCompare(b[p]));
});
$.fn.sortChildren = function(op) {
op = $.extend({

}, op);
return this.each(function() {
const i = $(this).prop("selectedIndex");
$(this).html(sort($(this).children(), op.by, op.order)).prop({selectedIndex: i});
});
};
// 1. example: sorting by value, order "asc" (default)
$("#test_1").sortChildren({by: "value"});
// 2. example: sorting by textContent (default), order "desc"
$("#test_2").sortChildren({order: "desc"});
