jQuery attribute disable not working

I'm try to disable (and remove) some attributes in jQuery, but it seems not working when value is changed and set to "disabled" some fields. This script runs when a value of drop-down box is changed.

Here code below:

$(".tipo_frete").change(function(){
    if($(this).val()  == "FOB" ){
        $(".id_transp").attr("disabled");
        $(".id_transp").val("");
        $(".nome_transp").attr("disabled");
        $(".nome_transp").val("");
        $(".valor_frete").attr("disabled");                     
        $(".valor_frete").val("");                      
    }else{
        $(".id_transp").removeAttr("disabled");
        $(".valor_frete").removeAttr("disabled");           
        $(".nome_transp").removeAttr("disabled");           
    }
});

Did I do something wrong here?

In jQuery when you want to get attribute value, must be use .attr('key') or .prop('key') with one argument, But when you want to set a value to an attribute, you must set two arguments like as .attr('key', 'value') or .prop('key', 'value')

$(".id_transp").attr("disabled", "disabled");

//OR

$(".id_transp").prop("disabled", true);

use prop()

disable

$(".id_transp").prop("disabled",true);

enable

$(".id_transp").prop("disabled",false);

NOTE : $(".id_transp").attr("disabled"); you have to pass 2 arguments like $(".id_transp").attr("disabled",true)

simplify your code

$(".tipo_frete").change(function () {
    if ($(this).val() == "FOB") {
        $(".id_transp,.nome_transp,.valor_frete").val("").prop("disabled", true);
    } else {
        $(".id_transp,.nome_transp,.valor_frete").prop("disabled", false);
    }
});

Yes, you are missing another parameter in attr() property.
Try this:

$(".tipo_frete").change(function(){
    if($(this).val()  == "FOB" ){
        $(".id_transp").attr("disabled","disabled");
        $(".id_transp").val("");
        $(".nome_transp").attr("disabled","disabled");
        $(".nome_transp").val("");
        $(".valor_frete").attr("disabled","disabled");                      
        $(".valor_frete").val("");                      
    }else{
        $(".id_transp").removeAttr("disabled");
        $(".valor_frete").removeAttr("disabled");           
        $(".nome_transp").removeAttr("disabled");           
    }
});

But when you remove those attibutes, you keep only one parameter inside and it will be removed.

element equal to selector '.id_transp';

  var $element = $(...);
        $element.prop('disabled', true);
        $element.attr('disabled', true); 

        // The following do not require jQuery
        $element.get(0).disabled = true;
        $element.get(0).setAttribute('disabled', true);
        $element[0].disabled = true;
        $element[0].setAttribute('disabled', true);
