如何通过jQuery获取<TD>标签具有KK属性的<TR>标签的属性值？

Question

我需要获取TR标签的"pp“属性值，该TR标签有一个具有"KK”属性的TD标签。

<TR pp="I hava to read this.">
    <TD kk >  </TD>
</TR>
<TR pp="Don't want this...">
    <TD > </TD>
</TR>

如何使用单行jQuery命令执行此操作？

Answer 1

试一试

var elem = $("tr td").filter(function(i, el) {
  return $(el).attr("kk") !== undefined
}).parent("tr").attr("pp");

​

var elem = $("tr td").filter(function(i, el) {
  return $(el).attr("kk") !== undefined
}).parent("tr").attr("pp");

console.log(elem)

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table>
<TR pp="I hava to read this.">
    <TD kk>  </TD>
</TR>
