Jquery- Get the value of first td in table

Question

I am trying to get the value of first td in each tr when a users clicks \"click\".

The result below will output aa ,ee or ii. I was thinking about using closest(\'t

Answer 1

This should work:

$(".hit").click(function(){    
   var value=$(this).closest('tr').children('td:first').text();
   alert(value);    
});

Explanation:

• .closest('tr') gets the nearest ancestor that is a <tr> element (so in this case the row where the <a> element is in).
• .children('td:first') gets all the children of this element, but with the :first selector we reduce it to the first <td> element.
• .text() gets the text inside the element

As you can see from the other answers, there is more than only one way to do this.

Answer 2

In the specific case above, you could do parent/child juggling.

$(this).parents("tr").children("td:first").text()

Answer 3

$(this).parent().siblings(":first").text()

parent gives you the <td> around the link,

siblings gives all the <td> tags in that <tr>,

:first gives the first matched element in the set.

text() gives the contents of the tag.

Answer 4

$(".hit").click(function(){
   var values = [];
   var table = $(this).closest("table");
   table.find("tr").each(function() {
      values.push($(this).find("td:first").html());
   });

   alert(values);    
});

You should avoid $(".hit") it's really inefficient. Try using event delegation instead.

Answer 5

Install firebug and use console.log instead of alert. Then you will see the exact element your accessing.

Answer 6

If you need to get all td's inside tr without defining id for them, you can use the code below :

var items = new Array();

$('#TABLE_ID td:nth-child(1)').each(function () {
      items.push($(this).html());
});

The code above will add all first cells inside the Table into an Array variable.

you can change nth-child(1) which means the first cell to any cell number you need.

hope this code helps you.
