Javascript 如何为List.js编写排序函数？

我使用list.js对表中的数据进行简单排序。排序功能工作正常，但我想修改它的初始行为。当用户第一次看到该表时，他/她应该将某个特定值的记录放在一列的顶部（本例中使用我的本地货币）。就在最初，以后的排序应该以标准方式工作

让我们看看代码：

<table id="accountsList">
<thead>
    <tr>
        <th scope="col" class="sort" data-sort="currency-td" aria-role="button"><span>Currency</span></th>
        <th scope="col" class="sort" data-sort="accountNo-td" aria-role="button"><span>Account number</span></th>
        <th scope="col" class="sort td-centered" data-sort="used-td" aria-role="button"><span>Used</span></th>
    </tr>
</thead>
<tbody class="list">
    <tr>
        <td class="currency-td">EUR</td>
        <td class="accountNo-td">53106010151036926643566665</td>
        <td class="used-td td-centered">
            <input type="checkbox" checked>
        </td>
    </tr>
     <tr>
        <td class="currency-td">PLN</td>
        <td class="accountNo-td">83106010151036926643522665</td>
        <td class="used-td td-centered">
            <input type="checkbox">
        </td>
    </tr>
     <tr>
        <td class="currency-td">PLN</td>
        <td class="accountNo-td">59996010151036926643566665</td>
        <td class="used-td td-centered">
            <input type="checkbox" checked>
        </td>
    </tr>
     <tr>
        <td class="currency-td">USD</td>
        <td class="accountNo-td">33106010151036999643566675</td>
        <td class="used-td td-centered">
            <input type="checkbox">
        </td>
    </tr>
</tbody>

你有什么想法吗？：）

尝试使用List.js的字母表功能，如：

var options = {
    valueNames: ['currency-td', 'accountNo-td', 'used-td']
};

var accountsList = new List('accountsList', options);

accountsList.sort("currency-td", { alphabet: "PLNABCDEFGHIJKMOQRSTUVXYZplnabcdefghijkmoqrstuvxyz" }
);

这里有记录

我是这样想的：

accountsList.sort('currencyTd', {
        order: 'asc',
        sortFunction: function (a, b) {
            if ((a.currencyTd === 'PLN') != (b.currencyTd === 'PLN')) {
                return a.currencyTd === 'PLN' ? 1 : -1;
            }
            return a.currencyTd > b.currencyTd ? 1 :
                   a.currencyTd < b.currencyTd ? -1 : 0;
        }
    });

accountsList.sort（'currencyTd'{
订单：“asc”，
sortFunction:函数（a，b）{
如果（（a.currencyTd=='PLN'）！=（b.currencyTd=='PLN'））{
返回a.currencyTd==‘PLN’？1:-1；
}
返回a.currencyTd>b.currencyTd？1：
a、 currencyTd

建议的解决方案如下：

我认为这确实会将“PLN”记录放在首位，但恐怕它也有副作用。例如，在本例中，“NGN”将位于“JPY”之前。我只需要“PLN”例外。

var options = {
    valueNames: ['currency-td', 'accountNo-td', 'used-td']
};

var accountsList = new List('accountsList', options);

accountsList.sort("currency-td", { alphabet: "PLNABCDEFGHIJKMOQRSTUVXYZplnabcdefghijkmoqrstuvxyz" }
);

accountsList.sort('currencyTd', {
        order: 'asc',
        sortFunction: function (a, b) {
            if ((a.currencyTd === 'PLN') != (b.currencyTd === 'PLN')) {
                return a.currencyTd === 'PLN' ? 1 : -1;
            }
            return a.currencyTd > b.currencyTd ? 1 :
                   a.currencyTd < b.currencyTd ? -1 : 0;
        }
    });
