JQuery - 获取单选按钮旁边的 td 值
我有以下困境: 我的 HTML 是这样的(这存在于 PL/SQL 应用程序中。):
<table id="search_result_table">
<tr>
<input type=radio name="pv_select" value="'||lv_spriden_id||'"/>
<font face="Calibri" size=3><td id="spriden_id" name="spriden_id">'||lv_spriden_id||'</td></font>'
<font face="Calibri" size=3><td id="last_name" class="c_last_name" name="last_name">'||lv_spriden_last_name||'</td></font>
<font face="Calibri" size=3><td id="first_name" class = "c_first_name" name="first_name">'||lv_spriden_first_name||'</td></font>
</tr>
</table>
我可以通过以下方式获取选定的单选按钮值:
$("input[name=pv_select]:checked").val()
但是,我希望能够获取“last_name”列单元格的值(它存在于单选按钮旁边的表中)。如何通过 jQuery 检索该值(通过单选按钮获取所选行)?
我已经尝试了几件事,但没有一个起作用:
$("input[name=pv_select]:checked").parent().siblings("td:eq(1)").text());
提前致谢。
I have the following dilemma:
My HTML is as such (this exists within a PL/SQL app.):
<table id="search_result_table">
<tr>
<input type=radio name="pv_select" value="'||lv_spriden_id||'"/>
<font face="Calibri" size=3><td id="spriden_id" name="spriden_id">'||lv_spriden_id||'</td></font>'
<font face="Calibri" size=3><td id="last_name" class="c_last_name" name="last_name">'||lv_spriden_last_name||'</td></font>
<font face="Calibri" size=3><td id="first_name" class = "c_first_name" name="first_name">'||lv_spriden_first_name||'</td></font>
</tr>
</table>
I am able to get at the selected radio button value via:
$("input[name=pv_select]:checked").val()
However, I would like to be able to get the value of the "last_name" column cell (which exists within a table next to the radio button). How can I retrieve this value (for the selected row via the radio button) via jQuery?
I've tried several things, but none are working:
$("input[name=pv_select]:checked").parent().siblings("td:eq(1)").text());
Thanks in advance.

HTML 无效;不确定这是否会弄乱你的 DOM 树,从而在 jQuery 试图遍历损坏的 DOM 树时让 jQuery 感到困惑。
这是有效的 HTML:
和 jQuery,用于获取与选中的单选按钮同一行中的“姓氏”表格单元格的值:(
我说 HTML 是有效的:
id
属性的值是指在 HTML 页面中是唯一的,因此如果有多行表单元格使用相同的 id 属性,这也是无效的。)The HTML is invalid; not sure if that’s mucking up your DOM tree, and thus confusing jQuery as it tries to traverse the broken DOM tree.
Here’s valid HTML:
And jQuery to get the value of the “last name” table cell in the same row as the checked radio button:
(I say the HTML is valid: values for the
id
attribute are meant to be unique within an HTML page, so if you have multiple rows using the same id attributes for the table cells, that’s invalid too.)我刚刚意识到这在 Firefox 中有效,但在 IE 中无效。因此,我将分析可能导致在一种浏览器中失败的原因,而不是在另一种浏览器中。
I just realized that this works in Firefox, yet not in IE. Hence, I shall be analyzing what may be causing for this to fail in one browser and not the other.
您的选择器适用于一个通用表,其中 td 中有一个输入,而另一个 td 中有姓氏文本,
也许您的问题是姓氏是在之后声明的提交,所以你应该尝试修改选择器,其中
我刚刚更改了兄弟的索引(如果我正确地获取了你的表转储,你的 .siblings("td:eq(1)") 是名字,eq( 0) 应该是姓氏)
只是一个建议..

当您发布 html 摘录时,我意识到,您不需要检查无线电父级的同级元素。因为它的父级是 tr 并且表中 tr 的同级只是另一个表行。
您可能会考虑使用遍历函数 .next() ,它会移动到 DOM 中的下一个元素。
遗憾的是,我无法在 FF 中对此进行足够的测试(或者只是因为 Firebug / jquery ext.),但是这是您确切要求的代码(获取无线电输入的下一个元素):
唯一的问题是,下一个元素是 font 元素,我似乎无法在 FF 中正确渲染(并且不' t 驻留在表格行中 - 它直接显示在 FireBug 检查器中的 body 内),因此 .children() 无法找到 或您所在的任何 td试图找到
You selector works on a generic table with an input in td and last name text in another td
maybe your problem is that last name is declared after the submit, so you should try to modify the selector with
where I just changed index of sibling (if I got your table dump correct, your .siblings("td:eq(1)") is First Name, eq(0) should be last name)
Just a suggestion..
EDIT
When you posted your html excerpt, I realized, that you don't need to check sibling elements of radio's parent. As its parent is tr and siblings of tr in table are just another table rows.
What you may consider is using traversing function .next() which moves to next element in the DOM
It's sad, that I cannot test this enough in FF (or just because Firebug / jquery ext.), but this is the code, you exactly asked for (get next element of radio input):
the only problem is, that next element is font element, which I cannot seem to render properly in FF (and doesn't reside in the table row - it displays directly inside body in FireBug inspector), so .children() cannot find or whatewer td you are trying to find
