【问题描述】：
好的，所以我有这个 jQuery 表函数 (https://jsfiddle.net/51Le6o06/7/)，它可以完美地与同一页面上的多个表一起使用。
我想修改表格和函数（新小提琴https://jsfiddle.net/51Le6o06/16/），以便每一行（.product-data-row）携带一个信息行（.product-information-row）[子行]，如您所见在这个小提琴中。
<tr class="product-data-row">
<td>data</td>
<td>data</td>
<td>data</td>
<td><span class="handsetcost">£364.00 upfront</span>
<br><span class="amount">£10.10 per month</span></td>
</tr>
<tr class="product-information-row">
<td colspan="100%">£364.00 upfront<br>£10.10 per month</td>
</tr>
现在，每个 (.product-data-row) 在其下方都有一个 (.product-information-row)，其中包含有关 (.product-data-row) 的信息，目前在上面的示例中，它只包含重复的信息。
从早期的表函数继承现有的 jQuery 函数，页面加载函数应该 - 通过搜索类 (.amount) 在页面加载时对表行进行排序，然后按升序重新排列行，以便最便宜的交易（每月）是第一位的。哪个不再起作用了。
还有一个过滤器通过仅显示具有类 (.free) 的行来过滤表行（从上一个表结转） - 这也是错误的，因为我希望信息行与包含 ( .free)。
每个 (.product-information-row) 都特定于其正上方的 (.product-data-row)。我如何修改 jQuery 以适应这一点。并使表格的功能与它的前身一样，使用额外的信息行。
我在这里要做的是隐藏表格行的数据，最终将在单击表格行时显示并最终向下滑动，但我似乎无法让它像 DataTables 的子行一样工作用途，如果有人有任何替代方法或想法，请在 cmets 中告诉我。
前身的 jQuery（需要修改才能工作）
jQuery.fn.extend({
sortPaging: function() {
return this.each(function() {
var container = $(this);
var dataRows = [];
/**
* Create an array of all rows with its value (this assumes that the amount is always a number.
* You should add error checking!!
* Also assumes that all rows are data rows, and that there are no header rows. Adjust selector appropriately.
*/
container.find('.internalActivities > tbody > tr').each(function(i, j) {
dataRows.push({
'amount': parseFloat($(this).find('.amount').text().replace(/£/, "")),
'row': $(this)
});
})
//Sort the data smallest to largest
dataRows.sort(function(a, b) {
return a.amount - b.amount;
});
//Remove existing table rows. This assumes that everything should be deleted, adjust selector if needed :).
container.find('.internalActivities > tbody').empty();
//Add rows back to table in the correct order.
dataRows.forEach(function(ele) {
container.find('.internalActivities > tbody').append(ele.row);
})
var trs = container.find(".internalActivities tbody tr");
var btnMore = container.find(".seeMoreRecords");
var btnLess = container.find(".seeLessRecords");
var trsLength = trs.length;
var currentIndex = 4,
page = 4;
trs.hide();
trs.slice(0, currentIndex).show();
checkButton();
btnMore.click(function(e) {
e.preventDefault();
trs.slice(currentIndex, currentIndex + page).show();
currentIndex += page;
checkButton();
});
btnLess.click(function(e) {
e.preventDefault();
trs.slice(currentIndex - page, currentIndex).hide();
currentIndex -= page;
checkButton();
});
function checkButton() {
var currentLength = trs.filter("tr:visible").length;
if (currentLength >= trsLength) {
btnMore.hide();
} else {
btnMore.show();
}
if (trsLength > page && currentLength > page) {
btnLess.show();
} else {
btnLess.hide();
}
}
container.find('.filter-free').change(function() {
var $all = container.find(".internalActivities tbody tr").hide();
trs = this.checked ? $all.has('.free') : $all;
trsLength = trs.length;
trs.slice(0, page).show();
currentIndex = page;
});
container.find('.filter-free').click(function() {
container.find('.seeLessRecords').hide();
});
})
}
});
$('.sort_paging').sortPaging();
