我不知道什么应该是一个简单的任务:

http://jsfidle.net/elen/7agUc/3/

$(document).on("change", td[col=cat_id] select ,function() {
    var v = $(this).val();
    var tr = $(this).parent().parent(); // getting parent row

    var tr_id = tr.attr( primary_key );
    var d = tr.childern( td[col=Artist ).html(); // getting text in the specific cell of the same row

    alert(d);

});

上述代码投出错误 - “ 子女方法不支持 ”

下列作品:

var d = $("tr[primary_key="+tr_id +"] td[col=Artist]").text();

但为何我不能只使用 childs () 或 find () : :

var d = tr.find( td[col=Artist ).text();

还是我漏掉了什么?

Answer 1

您有一个打字符: 将 chiltern 替换为 children 。

Answer 2

固定下行:

var d = tr.childern( td[col=Artist ).html();

收件人:

var d = tr.children( td[col=Artist] ).html();

Answer 3

在选择器里你少了一个, 加上你拼错孩子的拼法。尝试使用 :

 tr.children( td[col=Artist] ).html()

Answer 4

尝试此 - & gt;

$(document).on("change", td[col=cat_id] select ,function() {
    var v = $(this).find( option:selected ).val();
    var tr = $(this).parent().parent();

    var tr_id = tr.attr( primary_key );
    var d = tr.find( td[col=Artist] ).html();

    alert(d);

});
