修改现有的jQuery表排序+过滤函数(子行)

标签: javascript jquery html

好的,我有这个jQuery表函数(https://jsfiddle.net/51Le6o06/7/),可以在同一页面上与多个表完美配合。

我想修改表和函数(new fiddle https://jsfiddle.net/51Le6o06/16/),以便每行(.product-data-row)都带有一个信息行(.product-information-row)[子行]可以看到这个小提琴。

void playSound(){
     float transpose = -4; 
     float note = -1; 
     if (Input.GetKeyDown("a")) note = 0;  // C
     if (Input.GetKeyDown("s")) note = 2;  // D
     if (Input.GetKeyDown("d")) note = 4;  // E
     if (Input.GetKeyDown("f")) note = 5;  // F
     if (Input.GetKeyDown("g")) note = 7;  // G
     if (Input.GetKeyDown("h")) note = 9;  // A
     if (Input.GetKeyDown("j")) note = 11; // B
     if (Input.GetKeyDown("k")) note = 12; // C
     if (Input.GetKeyDown("l")) note = 14; // D

     if (note>=0){ // if some key pressed...
         audio.pitch =  Mathf.Pow(2, (note+transpose)/12.0);
         audio.Play();
}

每个(.product-data-row)现在直接在其下面有一个(.product-information-row),它带有关于(.product-data-row)的信息,现在在上面的示例中它只包含重复信息。

从早期的表/ s函数中继承现有的jQuery函数,页面加载函数应该 - 通过搜索类(.amount)对页面加载的表行进行排序,然后按升序重新排列行,以便最便宜的交易(每月)是第一个。哪个不再有效。

还有一个过滤器通过仅显示带有类(.free)的行来过滤表行(从前一个表继承) - 这也是错误的,因为我希望信息行显示在包含的行旁边( 。免费)。

每个(.product-information-row)特定于上面的(.product-data-row)。如何修改jQuery以适应这种情况。并使表格的功能成为它的前身对额外信息行的作用。

我在这里尝试做的是有一个表格行的隐藏数据,最终会在点击表格行时显示并最终向下滑动,但我似乎无法使其工作类似于DataTables使用的子行,如果有人有任何替代方法或想法,请在评论中告诉我。

来自前任的jQuery(需要修改工作)

<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>

您的代码中存在许多未解决的问题,因此快速修复需要花费超过一小时的时间。尝试通过下面的代码,希望你会得到一些想法(并请下次尝试更准确地提出问题,或者将其分成几个问题,以便得到快速简洁的答案):

jQuery.fn.sortPaging = function(options) {

		var buttonFree = container.find('.filter-free');
		var tableRows = [];

		var filterFree = buttonFree.is(':checked');
		function displayRows() {
			tableBody.empty();
			var displayed = 0;
			$.each(dataRows, function(i, ele) {

					tableBody.append(ele.thisRow).append(ele.nextRow);

				};
			});
			tableBody.find('.product-data-row').on('click', function(e){

		};

        dataRows.sort(function(a, b) {
            return a.amount - b.amount;
        });

        tableRows = tableBody.find("tr");

        buttonMore.on('click', showMore);
