Question

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>

</tbody>

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;
}

ITs very bad. I know. 🙂

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();
        })
    });

})

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.net/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();
        })
    });

})
