我正在尝试构建一个函数来减轻元素的一些手动方面。客户向我提供了一个 Excel 列表，我已将其转换为表格(感谢 Notepad++ 和一些漂亮的 jQuery 脚本)。
我的目标是制作所有列的单独列表，每个列都包含列标题和 “X” 单元格，但是“X” 单元格中的文本将与第一个 <td> 匹配每行。
我尝试了一下但失败了，所以我希望有人能看到我的目标并指出我的缺陷。
我采用的方法是将所有内容放入一个整齐定向的数组中，然后我将遍历该数组以创建 <div><ul><li>Column Header</li><li>text from first Row (X replaced)</li> etc...</ul></div>
我怀疑我的行迭代和列迭代是倒退的，但我们将不胜感激。
This StackOverflow post有我需要的要点，但没有我想要的那么全面。
$('td').each(function() {
var currentHTML = $(this).html().toString();
if (currentHTML === " ") {
$(this).text("").addClass('nonX');
}
});
var columnIteration = $('tr:eq(0)').find('td').length;
console.log(columnIteration);
var corespondingTD = [];
for (i = 1, z = columnIteration; i < z; i++) {
$('tr').each(function() {
var rowIterated = [];
var columnHeader = $('tr:eq(0)').find($('td').eq(i)).text();
var xTD = $(this).find($('td').eq(i)).not($('td.nonX'));
rowIterated.push(columnHeader);
rowIterated.push(xTD);
corespondingTD.push(rowIterated);
});
}table {
border: solid 1px #000;
border-collapse: collapse;
}
td {
border: solid 1px #000;

</table>最佳答案
这是一个最小的例子，它有一个更简单的表，它创建一个对象，该对象包含与 x 标识的列标题相对应的属性，其值是相应行标题的数组。我在那里留下了一些日志记录行，这样您就可以看到代码发生了什么，因为它计算出每个 x 的行和列标题值:
var lists = {};
buildLists();
console.log(JSON.stringify(lists, null, 2));
function buildLists() {
$('#data tbody tr td').each(function() {
var columnIndex = $(this).parent().children().index($(this));
var rowIndex = $(this).parent().parent().children().index($(this).parent());
if ($(this).html() == 'x') {
var columnHeader = getTableCellValue('data', 0, columnIndex);
var rowHeader = getTableCellValue('data', rowIndex, 0);
//console.log('hit at ' + rowIndex + ' ' + columnIndex);
//console.log(getTableCellValue('data', rowIndex, columnIndex));
//console.log(columnHeader + ' : ' + rowHeader);
if (!lists[columnHeader]) {
lists[columnHeader] = [];
}
lists[columnHeader].push(rowHeader);
};
});
};
function getTableCellValue(tableId, rowIndex, columnIndex) {
var cell = $('#' + tableId + ' tr').eq(rowIndex).find('td').eq(columnIndex)
return cell.text();
}table {
border: solid 1px #000;
border-collapse: collapse;
}
td {
border: solid 1px #000;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<body>
<table id="data">
<tbody>
<tr>
<td></td>
<td>foo</td>
<td>bar</td>
<td>baz</td>
</tr>
<tr>
<td>A</td>
<td>x</td>
<td></td>
<td></td>
</tr>
<tr>
<td>B</td>
<td>x</td>
<td></td>
<td>x</td>
</tr>
<tr>
<td>C</td>
<td></td>
<td>x</td>
<td>x</td>
</tr>
</tbody>
</table>
</body>使用你的表(我给它一个 id="data")，它仍然有效，但我认为你需要稍微修改一下解决方案，让你的对象属性名称少一些详细:
var lists = {};
buildLists();
console.log(JSON.stringify(lists, null, 2));
function buildLists() {
$('#data tbody tr td').each(function() {
var columnIndex = $(this).parent().children().index($(this));
var rowIndex = $(this).parent().parent().children().index($(this).parent());
if ($(this).html() == 'x') {
var columnHeader = getTableCellValue('data', 0, columnIndex);
var rowHeader = getTableCellValue('data', rowIndex, 0);
//console.log('hit at ' + rowIndex + ' ' + columnIndex);
//console.log(getTableCellValue('data', rowIndex, columnIndex));
//console.log(columnHeader + ' : ' + rowHeader);
if (!lists[columnHeader]) {
lists[columnHeader] = [];
}
lists[columnHeader].push(rowHeader);
};
});
};
function getTableCellValue(tableId, rowIndex, columnIndex) {
var cell = $('#' + tableId + ' tr').eq(rowIndex).find('td').eq(columnIndex)
return cell.text();
}table {
border: solid 1px #000;
border-collapse: collapse;
}
td {
border: solid 1px #000;
