Question

我有 ~~a jsFiddle set up~~ ，我一直在努力解决我的问题。

$('.docAdminFormSubmit').click(function() {
    buttonClicked = $(this).attr('name');

    if (buttonClicked == 'submitAddClassesToDoc') {
        AddClassesToDoc();
        return false;
    }
});

function AddClassesToDoc() {
    // Check if doc selected in dropdown
    var selectedDocID = '';
    if ($('select#docsList option:selected').val() == 0) {
        alert('No document selected');
        // No doc selected
        return false;
    } else {
        selectedDocID = $('select option:selected').val();
        //alert('selected Doc ID: ' + selectedDocID);
    }

    alert('Selected doc ID: ' + selectedDocID);

    // Check if any classes selected and add them to the array
    var classesToAddToDoc;
    if ($('input.chkAddClass:checked').length) {
        // At least one class checked
        // Get the id(s) of the checked class(es) that aren't already assigned to the selected document
        classesToAddToDoc = $('#classesTable input[name="classesToAddToDoc[]"]:checked').map(function() {
            var currentClassNumber = $(this).parent('td').next().text();

            alert('Current classID: ' + $(this).val() + ', currentClassNumber: ' + currentClassNumber );
            
            var found = false;

            $('#docsTable a[name="' + selectedDocID + '"]').parent().parent().parent().find('tr.docClassesRow').each(function() {
                alert('Doc\'s current class number: ' + $(this).find('td').last().html());

                if ($(this).find('td').last().html() == currentClassNumber ) {
                    alert('Class number ' + currentClassNumber + ' already assigned');
                    found = true;
                }
            })

                    alert('Adding ' + $(this).val() + ' to array');
                    return $(this).val();
                }

        }).get();
    } else {
        // No classes checked
        alert('No classes checked');

        return false;
    }

    alert('classesToAddToDoc: ' + classesToAddToDoc);
}

我需要能够将在表中检查的项目数组合在一起，但前提是选中的项目尚未与下拉列表中选择的内容相关联。不确定这对你是否有意义，但是当你看到小提琴时你应该明白我的意思。

最终，单击该按钮时，函数中的最终警报应仅显示在下拉列表中选择的文档的docTable中尚未列出的类的value属性。

OP在编辑中写道：

感谢至少检查一下，Levi。对不起，我不清楚解释应该发生什么。

然而，我终于按照需要开始工作了。 Here is a new working jsFiddle。（我搞砸了原来的一个并最终将其删除。）

$(function () {
    // create the chart
    $('#container').highcharts({
        chart: {
            events: {
                addSeries: function() {
                    alert ('A series was added, about to redraw chart');
                }
            }
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },

        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
        }]
    });


    // activate the button
    $('#button').click(function() {
        var chart = $('#container').highcharts();

        chart.addSeries({
            data: [216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5]
        });

        $(this).attr('disabled', true);
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>

<div id="container" style="height: 400px"></div>
<button id="button">Add series</button>

这是应该发生的事情：   用户从下拉列表中选择一个项目，然后检查下表中的框以指示他希望将哪些项目添加到文档中。顶部表格显示了当前为每个文档分配的类。

Fiddle的目的是将底部表格中的一组类ID放在一起，以添加到所选文档，但是如果用户选中了底部表格中的项目，并且已经为所选文档列出了该项目在顶部表中，不应将该类ID添加到数组中。

正如我所说，上面链接的小提琴是一个有效的例子。

如何根据另一个表的数据获取特定的表格单元格数据
