jQuery - find table row containing table cell containing specific text

jquerydom

提问by David

I need to get a trelement which contains a tdelement which contains specific text. The tdwill contain that text and only that text (so I need text = 'foo'not text contains 'foo'logic).

我需要获取一个tr元素,其中包含一个td包含特定文本的元素。在td将包含文本和只有文字(所以我需要text = 'foo'不是text contains 'foo'逻辑)。

So I need the equivalent of the following 'pseudo jQuery':

所以我需要等效于以下“伪 jQuery”:

var tableRow = $(table td[text = 'foo']).parent('tr');

Can anyone provide the correct syntax?

谁能提供正确的语法?

You can use filter()to do that:

您可以使用filter()来做到这一点:

var tableRow = $("td").filter(function() {
    return $(this).text() == "foo";
}).closest("tr");

I know this is an old post but I thought I could share an alternative [not as robust, but simpler] approach to searching for a string in a table.

我知道这是一篇旧帖子,但我想我可以分享另一种[不是那么健壮,但更简单]的方法来搜索表中的字符串。

$("tr:contains(needle)");//where needle is the text you are searching for.

$("tr:contains(needle)");//其中,needle 是您要搜索的文本。

For example, if you are searching for the text 'box', that would be:

例如,如果您要搜索文本“box”,则为:

$("tr:contains('box')");

This would return all the elements with this text. Additional criteria could be used to narrow it down if it returns multiple elements

这将返回带有此文本的所有元素。如果它返回多个元素,则可以使用其他条件来缩小范围

回答by Rezler

$(function(){
    var search = 'foo';
    $("table tr td").filter(function() {
        return $(this).text() == search;
    }).parent('tr').css('color','red');
});

Will turn the text red for rows which have a cell whose text is 'foo'.

将具有文本为“foo”的单元格的行的文本变为红色。

This will search text in all the td's inside each tr and show/hide tr's based on search text

这将在每个 tr 内的所有 td 中搜索文本,并根据搜索文本显示/隐藏 tr

 $.each($(".table tbody").find("tr"), function () {                              

                if ($(this).text().toLowerCase().replace(/\s+/g, '').indexOf(searchText.replace(/\s+/g, '').toLowerCase()) == -1)
                    $(this).hide();
                else
                    $(this).show();
 });

   <input type="text" id="text" name="search">
<table id="table_data">
        <tr class="listR"><td>PHP</td></tr>
        <tr class="listR"><td>MySql</td></tr>
        <tr class="listR"><td>AJAX</td></tr>
        <tr class="listR"><td>jQuery</td></tr>
        <tr class="listR"><td>JavaScript</td></tr>
        <tr class="listR"><td>HTML</td></tr>
        <tr class="listR"><td>CSS</td></tr>
        <tr class="listR"><td>CSS3</td></tr>
</table>

$("#textbox").on('keyup',function(){
        var f = $(this).val();
      $("#table_data tr.listR").each(function(){
            if ($(this).text().search(new RegExp(f, "i")) < 0) {
                $(this).fadeOut();
             } else {
                 $(this).show();
            }
        });
    });

DemoYou can perform by search() method with use RegExp matching text

Demo您可以通过 search() 方法执行使用 RegExp 匹配文本
