Question

html structure:

 1,  <input id="edit-field-14sq-und-0-value" name="field_14sq[und][0][value]" value="" size="12" maxlength="10" class="form-text" type="text"></div>


2,  <input id="edit-field-15sq-und-0-value" name="field_14sq[und][0][value]" value="" size="12" maxlength="10" class="form-text" type="text"></div>

5 ,<input id="edit-field-18sq-und-0-value" name="field_14sq[und][0][value]" value="" size="12" maxlength="10" class="form-text" type="text"></div>

现在,如果1、2、3、投入箱具有价值,就可以在4、5中划出任何类型。

if the 4, 5, input box has value. then can t type anything in 1, 2, 3.

the following is my test code. but it can t work.

$(document).ready(function(){

$( #edit-field-14sq-und-0-value ).keyup(function() {
    if ($( #edit-field-16sq-und-0-value ).val().length > 0) {
        alert( you can t type them at the same time );
        $(this).val(  );
        $("#edit-field-15sq-und-0-value").val(  );
    }
})

});

the keyup function is give an error under firebug.

Edit: added "" to escape single quote in alert();
