I don't know jQuery speicifically, but my experience using Prototype was to have to class the rows <tr>, so that after each insert/delete, the CSS could apply appropriate styling for

tr.odd td

and

tr.even td

etc.

 

by: spulePosted on 2009-08-23 at 01:12:41ID: 25161748

$("#mytable tr:nth-child(2)").after("<tr><td>My</td><td>table</td><td>row</td></tr>"); //insert a new row after the second row
 
$("#mytable").append("<tr><td>My</td><td>table</td><td>row</td></tr>"); //insert a new row after the last row
 
$("#mytable").prepend("<tr><td>My</td><td>table</td><td>row</td></tr>"); //insert a new row before the first row
 
$("#mytable tr:nth-child(2)").remove(); //removes the second row

Oh yes, and for the odd/even styling:

Define the odd-row and even-row classes in your CSS:

#mytable .odd-row{
   background-color: blue;
}
#mytable .even-row{
   background-color: green;
}

After changing the table structure as shown in the above post, update the classes (You can't use the :odd and :even selectors in CSS because they're only in CSS3, but you can use them in jQuery.):

$("#mytable tr:odd").removeClass("even-row").addClass("odd-row");
$("#mytable tr:even").removeClass("odd-row").addClass("even-row");

spule. Very nice example. Should tbody be included in the selectors?

 

by: tankergoblinPosted on 2009-08-25 at 20:34:54ID: 25184233

Hi spule
for my add i have a button. and user will type in something to the text box and click add.
then it will add into the table. can i use method above to do it?

 

by: tankergoblinPosted on 2009-08-25 at 20:36:07ID: 25184236

also for below
$("#mytable tr:nth-child(2)").after("<tr><td>My</td><td>table</td><td>row</td></tr>"); //insert a new row after the second row


this is place at javascript tag or table tag. if table tag why do i need mytable?

 

by: spulePosted on 2009-08-26 at 00:22:05ID: 25185037

Yes, you can use that method. Try the code from the following snippet. Put it in the javascript tag.
I'm already involved in a very similar question and I've posted a full HTML page as an example. Please try it out: http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_24654655.html#25166292

$(document).ready(function(){ //this insures that the code is executed after the page is loaded
  $("#mybutton").click(function(){ //this binds the function to your button
    $("#mytable").append("<tr><td>"+$("#mytextbox").val()+"</td><td>table</td><td>row</td></tr>");
  });
});
