Answer 1

看这样一段函数定义的代码就明白了function json_to_format_string(obj,deep){ var html = ""; var blank_string = ""; for (var i = 0; i < deep; i++) { blank_string += " "; }; for(var name in obj){ if (typeof(obj[name])=="object") { html += blank_string + name +": "+ "
"; html += json_to_format_string(obj[name],deep+1); }else{ html += blank_string + name +": "+ obj[name]+"
"; } } return html;}
