javascript - ExpandCollapse table rows with nested rows

I want to create a table with the following structure:
Row1 datacolumn1 datacolumn2 datacolumn2
SubRow1 datacolumn1 datacolumn2 datacolumn2
SubRow2 datacolumn1 datacolumn2 datacolumn2
SubRow3 datacolumn1 datacolumn2 datacolumn2

I want to the subrows to expand/collapse on click. I just cant seem to make it work with tables. I know lists would be a better option but tables are much easier to maintain.

<tbody>
    <tr class="row1 head1">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr class="row1 head2 closed">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr class="row1 head3">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr class="row1 head4">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr class="row1 head5">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr class="row2 head1">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>

    <tr class="row2 head4">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr class="row2 head5">
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr>
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>
    <tr>
        <td>Cash and Equivalents</td>
        <td>000,000</td>
        <td>000,000</td>

    </tr>

on row click, i call the following function:

holdingsTree: function(that){
    var stack = '',
        classes = ba.splitClasses(that.attr('class')),
        nextRow = ba.getClassNumber(classes[1], "head");

    if (that.next().hasClass('head'+nextRow)){
        if (that.next().hasClass(classes[0]) && that.next().hasClass('open')){
            that.nextUntil('.head1').hide().addClass('closed').removeClass('open');
        } else if (that.next().hasClass(classes[0])){
            stack = that.nextUntil('.head1');
            $.each(stack, function(i, item){ if ($(item).hasClass('head' + (nextRow))){ $(this).show().addClass('open').removeClass('closed'); } });
        }
    } else if (that.next().hasClass('head'+ (nextRow+1))){
        if (that.next().hasClass(classes[0]) && that.next().hasClass('open')){
            that.nextUntil('.head1').hide().addClass('closed').removeClass('open');
        } else if (that.next().hasClass(classes[0])){
            stack = that.nextUntil('.head1');
            $.each(stack, function(i, item){ if ($(item).hasClass('head' + (nextRow+1))){ $(this).show().addClass('open').removeClass('closed'); } });
        }
    } else if (that.next().hasClass('head'+ (nextRow+2))){
        if (that.next().hasClass(classes[0]) && that.next().hasClass('open')){
            that.nextUntil('.head1').hide().addClass('closed').removeClass('open');
            return;
        } else if (that.next().hasClass(classes[0])){
            stack = that.nextUntil('.head'+ (nextRow+3));
            $.each(stack, function(i, item){ if ($(item).hasClass('head' + (nextRow+2))){ $(this).show().addClass('open').removeClass('closed'); } });
            //stack.find('.head'+(nextRow+2)).show().addClass('open').removeClass('closed');
        }
    } else if (that.next().hasClass('head'+ (nextRow+3))){
        if (that.next().hasClass(classes[0]) && that.next().hasClass('open')){
            that.nextUntil('.head1').hide().addClass('closed').removeClass('open');
        } else if (that.next().hasClass(classes[0])){
            stack = that.nextUntil('.head1');
            $.each(stack, function(i, item){ if ($(item).hasClass('head' + (nextRow+3))){ $(this).show().addClass('open').removeClass('closed'); } });
        }
    } else if (that.next().hasClass('head'+ (nextRow+4))){
        if (that.next().hasClass(classes[0]) && that.next().hasClass('open')){
            that.nextUntil('.head1').hide().addClass('closed').removeClass('open');
        } else if (that.next().hasClass(classes[0])){
            that.nextUntil('.head1').show().addClass('open').removeClass('closed');
        }
    } 

},

splitClasses: function(names){
    var names = names.split(' ');
    return names;
},

getClassNumber: function(name, pretext){
    var result = name.split(pretext);
    console.log(parseInt(result[1]) + 1);
    return parseInt(result[1]) + 1;
}

You can have a class for the rows you call parents, and a class for the rows you call children, and toggle their display.

Here's how:

$(document).ready(function() {

    function getChildren($row) {
        var children = [];
        while($row.next().hasClass('child')) {
             children.push($row.next());
             $row = $row.next();
        }            
        return children;
    }        

    $('.parent').on('click', function() {

        var children = getChildren($(this));
        $.each(children, function() {
            $(this).toggle();
        })
    });

})

Check this fiddle for the plete running code http://jsfiddle/T8t2r/3/ And please accept the answer if this solves your problem!

Good luck!

EDIT: to work on more levels one way is to have a level attribute. So here is the updated version which should work on any number of levels. http://jsfiddle/T8t2r/9/

$(document).ready(function() {

    function getChildren($row) {
        var children = [], level = $row.attr('data-level');
        while($row.next().attr('data-level') > level) {
             children.push($row.next());
             $row = $row.next();
        }            
        return children;
    }        

    $('.parent').on('click', function() {

        var children = getChildren($(this));
        $.each(children, function() {
            $(this).toggle();
        })
    });

})

It's hard to make out what you are trying to do from that example.

What you are trying to do should be fairly simple - what I'd do is rewrite from scratch, using the following concepts:

Give each clickable item (row) it's own ID, but have them all in one 'clickable' class
Give each sub row a class based off of the ID of the clickable parent - such as '[id]-sub'
Set up a click event on the 'clickable' class, where you determine the clicked Item ID, and use that to toggle (hide/show) all rows with class '[clicked ID]-sub'

Doing it that way, you should have much less code, and it should be much more readable.

Hope this helps...

You could do this:

$('.mySelectorOfNOTSubRow').toggle(
    function(){
        $(this).nextUntil('.mySelectorOfNOTSubRow').show();
    }, function(){
        $(this).nextUntil('.mySelectorOfNOTSubRow').hide();
});

HTML:

<table>
<tbody>
<tr class="head"><td></td></tr>
     <tr class="sub"><td></td></tr>
     <tr class="sub"><td></td></tr>
     <tr class="sub"><td></td></tr>
<tr class="head"><td></td></tr>
     <tr class="sub"><td></td></tr>
     <tr class="sub"><td></td></tr>
     <tr class="sub"><td></td></tr>
<tr class="head"><td></td></tr>
     <tr class="sub"><td></td></tr>
     <tr class="sub"><td></td></tr>
     <tr class="sub"><td></td></tr>
...
</tbody>
</table>

CSS:

.sub{display: none;}

Fiddle

As you are already using jQuery, you could go with the plugin datatales.

As you can see in the example section of the page, theres exactly what you are trying to achieve with your code.
