then its value automatically set to the text box & text box become read only…that’s ok..It’s my target..But I have little bit problem when I select a option (One,Two or Three).. If I again select the default value “===select option===” then automatically read only text field is not come normally(means read & write mode)…I want if I select “===select option===” option then text field will be automatically become normal mode….Can any one fix this problem by editing this code…thanxx in advanced…..

This works:

$(document).ready(function(e) {
    $("#myOption").change(function(){
        var textval = $(":selected",this).val(); 
        $('input[name=student_mark]').val(textval);
        myTestForm.student_mark.disabled=(!textval)?false:true;
    })
});​
