TypeError：representant为null，无法访问其属性“ company”

Question

正如您在下面看到的那样，我尝试了代表的console.log，它在控制台中为我生成了一个结果对象。该对象中包含公司，服务，contact_name和其他属性。但是，它总是说“ TypeError：代表是空的，无法访问它的属性” company”。

如何将“ typeof”并入此处，如此处所述：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/cant_access_property ....那将是解决方案吗？

jQuery.post(ajaxurl, data, function(response){

        if(response.length > 0){

            var html = '<ul>';

            jQuery.each(response,function( arrayID, representant ){

                html+= '<li><h3>'+representant.company +'</h3>';
                console.log(representant);
                html+='<p><b>Serving: </b>' + representant.serving + '<br />';
                html+='<b>Contact: </b>' + representant.contact_name + '<br/ ></p>';
                html+='<p><b>Address:</b> <br />' + representant.address + '<br />';
                html+= representant.city;
                html+= ', ';
                html+= representant.state_code;
                html+=' ';
                html+= representant.zip_code;
                html+='</p><p><b>Phone: </b>';
                html+= representant.phone;
                html+= '<br /> <b>Email: </b> ';
                html+= representant.email;
                html+='</p></li>';


            });

            html+= '</ul>';

        } else {
            html = 'We are sorry, we didn\'t found any Sales Representative on this area.';
        }

        display_results(html);

    });
}
