如何查找和更改 n 与 n 之间的乘法类n

我有一些表结构:

    <tr class="row-2"><tr>
    <tr class="row-3">..<tr>
    <tr class="row-4">..<tr>
    <tr class="row-5">..<tr>
    <tr class="row-6">..<tr>
    <tr class="row-7"><tr>
    <tr class="row-8">..<tr>
    <tr class="row-9">..<tr>
    <tr class="row-10">..<tr>
    <tr class="row-11">..<tr>
...etc

对于此示例,具有类“row-2”和“row-7”的 TR 是展开子行的父产品链接。

<script>
$(function() {
    $('tr.parent')
        .css("cursor","pointer")
        .css("color","red")
        .attr("title","Click to expand/collapse")
        .click(function(){
            $(this).siblings('.child-'+this.id).toggle();
        });
    $('tr[@class^=child-]').hide().children('td');
});
</script>

行 -3...-6 是行 2 的子行行-8...-11是行7的子行

我怎样才能找到行2,行7等,然后添加第二类“父”和ID类似的类(id =“row” -2”、id=“row-7”等)?另外,我需要在 row-2row-7 类之间添加等于上一个父行的每个 TR 。归根结底,我需要这样的东西:

        <tr class="row-2 parent" id="row-2"><tr>
        <tr class="row-3 child-row2">..<tr>
        <tr class="row-4 child-row2">..<tr>
        <tr class="row-5 child-row2">..<tr>
        <tr class="row-6 child-row2">..<tr>
        <tr class="row-7 parent" id="row-7"><tr>
        <tr class="row-8 child-row7">..<tr>
        <tr class="row-9 child-row7">..<tr>
        <tr class="row-10 child-row7">..<tr>
        <tr class="row-11 child-row7">..<tr>
..etc

I have some table structure:

    <tr class="row-2"><tr>
    <tr class="row-3">..<tr>
    <tr class="row-4">..<tr>
    <tr class="row-5">..<tr>
    <tr class="row-6">..<tr>
    <tr class="row-7"><tr>
    <tr class="row-8">..<tr>
    <tr class="row-9">..<tr>
    <tr class="row-10">..<tr>
    <tr class="row-11">..<tr>
...etc

for this example TR with classes "row-2" and "row-7" is parrent product link wich expand child rows.

<script>
$(function() {
    $('tr.parent')
        .css("cursor","pointer")
        .css("color","red")
        .attr("title","Click to expand/collapse")
        .click(function(){
            $(this).siblings('.child-'+this.id).toggle();
        });
    $('tr[@class^=child-]').hide().children('td');
});
</script>

Rows -3...-6 is child of row-2
and
Rows -8...-11 is child of row-7

How can I find row-2, row-7, etc then add second class "parent" and ID similar class (id="row-2", id="row-7", etc)? Also I need add in each TR between row-2 and row-7 class equal previous parent row. In bottom line I need something like this:

        <tr class="row-2 parent" id="row-2"><tr>
        <tr class="row-3 child-row2">..<tr>
        <tr class="row-4 child-row2">..<tr>
        <tr class="row-5 child-row2">..<tr>
        <tr class="row-6 child-row2">..<tr>
        <tr class="row-7 parent" id="row-7"><tr>
        <tr class="row-8 child-row7">..<tr>
        <tr class="row-9 child-row7">..<tr>
        <tr class="row-10 child-row7">..<tr>
        <tr class="row-11 child-row7">..<tr>
..etc

一种方法是对所有行执行两次传递,以设置所需的类和 ID。在第一遍中,添加与类名相同的 id,并将 parent 类添加到 row-2 和 row-7。在第二遍中,找到每个 .parent 行,并将 child- 类添加到其同级,直到下一个父级。这不是对 row-2 和 row-7 的值进行硬编码,而是假设所有标头项都包含在 元素内,而不是 < /代码> 元素。

这是一些代码: http://jsfiddle.net/vYTW2/

/**
 * Do a two pass on all rows to set them up.
 * In the first pass, add the same id as class, and
 * add the "parent" class to the row.
 *
 * Assuming all product header rows contain a
 * <th> element
 */
$('table tr th').each(function() {
    var row = $(this).parent('tr');
    var id = row.attr('class');
    row.attr('id', id);
    row.addClass('parent');
});

/**
 * In the second pass, run through all header rows
 * (that have the class parent) and mark all next siblings
 * with class "child-rowX" until we see the next parent row.
 */
$('tr.parent').each(function() {
    var id = $(this).attr('id');
    var className = 'child-' + id;
    $(this).nextUntil('.parent').addClass(className);
});

One way is to do a two-pass on all rows, to set up the required classes and id's. In the first pass, add an id same as the class name, and also add the parent class to row-2, and row-7. In the second pass, find each .parent row, and add child-<id> class to their siblings until the next parent. Instead of hard-coding the values for row-2 and row-7, this assumes that all header items are contained inside a <th> element, instead of a <td> element.

Here's some code: http://jsfiddle.net/vYTW2/

/**
 * Do a two pass on all rows to set them up.
 * In the first pass, add the same id as class, and
 * add the "parent" class to the row.
 *
 * Assuming all product header rows contain a
 * <th> element
 */
$('table tr th').each(function() {
    var row = $(this).parent('tr');
    var id = row.attr('class');
    row.attr('id', id);
    row.addClass('parent');
});

/**
 * In the second pass, run through all header rows
 * (that have the class parent) and mark all next siblings
 * with class "child-rowX" until we see the next parent row.
 */
$('tr.parent').each(function() {
    var id = $(this).attr('id');
    var className = 'child-' + id;
    $(this).nextUntil('.parent').addClass(className);
});
