Question

I have two checkboxes. each one have a sub form that is disable when the checkbox isn’t marked. i want on marking each checkbox its sub form get enabled.

I try this code but this works even the checkbox is not checked:

$("#form1").click(function(){
    if(":checked",this) { ..... }

 });

 $("#form2").click(function(){
    if(":checked",this) { ..... }

 });

would you help me?

You can use the jQuery is method:

if($(this).is(":checked")) {
    //It's checked!
}

What you have currently will always evaluate to true, because this will always be something truthy (not undefined or null for example).

Note that you need to pass this into jQuery because it will be a reference to the clicked DOM element itself, not a jQuery-wrapped element.
