js例外被抛出且未被接住

        var form = $("<form>");
        form.attr(‘style‘, ‘display:none‘);
        form.attr(‘target‘, ‘‘);
        form.attr(‘method‘, ‘post‘);
        form.attr(‘action‘, path);
        var input1 = $(‘<input>‘);
        input1.attr(‘type‘,‘hidden‘);
        input1.attr(‘name‘, ‘wjjson‘);
        input1.attr(‘value‘,‘11112d‘);
        $(‘body‘).append(form);        
        form.append(input1);
        form.submit();
        form.remove();
