当使用jQuery在同一行中选择另一个选择框时，如何禁用另一个选择框

Question

I want to do disable in another select box when the other selection box is selected (option value = 3) in the same row.

There are many rows in a table. In each row, there has three select box in each column. If I selected the select box in first column and the option value of selected box is 3, I want to make disable the second select box in the same row.

I wrote the code as the followings.

my code is not working when the new row added in the table after I click Add Row button. I need some guideline.

javascript :

<!-- add new row -->
<script>
    $(document).ready(function() {
        var id = 0;

        // Add button functionality
        $("#addrow").click(function() {
            id++;

            /*var master = $(this).parents("table.fancyTable");*/
            var master = $(this).parents("table.stdform");

            // Get a new row based on the prototype row
            var prot = master.find(".prototype").clone();

            prot.attr("class", "");
            /*prot.find(".id").attr("value", id);*/

            master.find(".fancyTable tbody").append(prot);

            $(".fancyTable tbody tr:nth-child(odd)").addClass("odd");
            $(".fancyTable tbody tr:nth-child(even)").addClass("even");
        });

    });
</script>
<!-- change select box -->
<script>
$(document).ready(function() {
    $('.processing_code').bind('change', function(){
    var data = $(this).val();
    alert(data);
    if(data == 3){
        $(this).parent('td').siblings().find(".parameter1").attr("disabled", "true");
    }
});
});
</script>

css :

<style>
 .fancyTable .prototype {
    display:none;
}
.odd{
 background-color: #ddd;
}
.even{
 background-color: #eee;
}
</style>

jsp :

<input type="button"
    name="btn_JobTempReg_addrow" class="mediumbutton"
    value="Add Row" id="addrow" />    
<div class="container_12 ">
        <div class="grid_job_mod height400">

Answer 1

try this..

<script>
$(document).ready(function() {
     $('.processing_code').bind('change', function(){
    var data = $(this).val();
    if(data == 3){
        $(this).parent('td').siblings()
               .find(".parameter1")
               .attr("disabled", "disabled");
    }
});
});
</script>

Answer 2

$('.processing_code').change(function() {
   if($(this).val() ==3)
      $(this).next('select').attr("disabled", "true");
   else
      $(this).next('select').attr("disabled", "false");
});
