javascriptjquery

提问by Vlad

I have this code in jQuery:

我在 jQuery 中有这个代码:

children('table').children('tbody').children('tr').children('td')

Which gets all table cells for each row. My question is: how can I get the text value in each cell in each row?

它获取每行的所有表格单元格。我的问题是:如何获取每行每个单元格中的文本值?

Should I use .each()to loop trough all children('td')? How can I get the text value of each td?

我应该.each()用来循环遍历所有children('td')吗?如何获取每个的文本值td

First of all, your selector is overkill. I suggest using a class or ID selector like my example below. Once you've corrected your selector, simply use jQuery's .each()to iterate through the collection:

首先,你的选择器是矫枉过正的。我建议使用类或 ID 选择器,如下例所示。一旦你更正了你的选择器,只需使用 jQuery 的.each()来遍历集合:

ID Selector:

ID选择器:

$('#mytable td').each(function() {
    var cellText = $(this).html();    
});

Class Selector:

类选择器:

$('.myTableClass td').each(function() {
    var cellText = $(this).html();    
});

Additional Information:

附加信息:

Take a look at jQuery's selector docs.

You can use .map: http://jsfiddle.net/9ndcL/1/.

您可以使用.maphttp: //jsfiddle.net/9ndcL/1/

// array of text of each td

var texts = $("td").map(function() {
    return $(this).text();
});

I would give your tds a specific class, e.g. data-cell, and then use something like this:

我会给你的 tds 一个特定的类,例如data-cell,然后使用这样的东西:

$("td.data-cell").each(function () {
    // 'this' is now the raw td DOM element
    var txt = $(this).html();
});

$(document).ready(function() {
  $('td').on('click', function() {
    var value = $this.text();
  });
});

$(".field-group_name").each(function() {
        console.log($(this).text());
    });
