Question

i got a table which has fields in each row . if field is empty i want the particular row with red border around it.

<table cellpadding="3" cellspacing="5" >
<tr>
<td class="cellformatting"><label>first name*</label></td>
<td class="cellformatting"><input id="fname" type="text" class="required searchfields" />
</td>
</tr>
<tr>
 <td class="cellformatting"><label>last name*</label></td>
<td class="cellformatting"><input id="lname" type="text" class="searchfields" /></td>
</tr>
</table>

i jst want the script if suppose last name is empty it should add some css around that particular row of table in which last name is shown.

Answer 1

How about something like this:

$(function(){

    checkBorder();

    $("table tr input").change(function(){
       checkBorder(); 
    });

});
function checkBorder(){
 $("table tr").each(function(){
    if ($(this).find("input").val() == ""){
       $(this).attr("class", "border");   
    }
});   
}

Here is a version which works without “Normalized CSS”, but the cell-spacing had to be removed:
