How to get the value in td tag with jquery

jQuery is a popular JavaScript library that can easily manipulate HTML elements through simple syntax. Sometimes we need to get the value in the TD tag in a table, then jQuery can help a lot.

In jQuery, you can use a selector to get HTML elements. Selectors are one of the core features of jQuery, and elements can be obtained based on the syntax of CSS selectors. We can use the following code to get the TD elements in a table:

$('table td')

$('table tr:eq(0) td')
$('table tr td:eq(0)')

The first piece of code will get all the TD elements in the first row of the table, and the second piece of code will get All TD elements in the first column of the table. Among them, :eq(0) means selecting the first element.

After obtaining the TD element, we can use jQuery's .text() or .html() method to obtain the text or HTML content in the TD element:

$('table td').text();
$('table td').html();

The above code will The text or HTML content of the TD element is returned as a string. If we just need to get the value of a certain TD element, we can use the following code:

$('table td:eq(0)').text();

The above code will get the text content of the first TD element in the table.

If you need to get the attribute value of the TD element, you can use the .attr() method:

$('table td').attr('data-id');
