我正在尝试使用Jquery编辑按钮单击时引导表的值。我从这篇文章中获得了参考资料，使行可编辑而且效果非常好。我遇到的唯一问题是双击按钮进入编辑模式。这是我的代码片段
$('.editbtn').click(function () {
var currentTD = $(this).parents('tr').find('td');
if ($(this).html() == 'Edit') {
currentTD = $(this).parents('tr').find($("td").not(":nth-child(1)"));
$.each(currentTD, function () {
$(this).prop('contenteditable', true).css({
'background':'#fff',
'color':'#000'
})
});
} else {
$.each(currentTD, function () {
$(this).prop('contenteditable', false).removeAttr("style");
});
}
$(this).html($(this).html() == 'Edit' ? 'Save' : 'Edit')
if ($(this).html() == 'Save'){
$(this).prop('contenteditable',false)
}
});<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

</table>在这里，我禁用了编辑一列中的数据。正如您所看到的，当我们单击第一行中的编辑按钮时，只需要单击一次，但对于其余行，则需要多次单击。在多次单击后，它将处于编辑模式下单击，直到刷新页面。我不知道我错过了哪里。我将感谢你的帮助。
问题是这一行：在执行$(this).html()时，它考虑了line。
<button type="button" class="btn btn-primary editbtn" >
Edit
</button>
为什么它在下次点击时起作用，因为在您的代码中，您更改为编辑
$(this).html($(this).html() == 'Edit' ? 'Save' : 'Edit')
您可以尝试以下操作：
使用$(this).text().trim()或更正行：
<button type="button" class="btn btn-primary editbtn" >Edit</button>
