javascript调试必备代码：打印对象或数组函数 vardump()

function vardump(obj,objname,deep){ deep = deep||1; if(deep > 5) return ""; deep++; /* 不是对象也不是数组 */ if(typeof(obj) != 'object' && typeof(obj) != 'array'){ document.writeln("<div>"+objname+"不是对象或者数组["+typeof(obj)+"]</div>"); return ''; } /* 开始打印 */ document.writeln("<ul>"); for(var i in obj){ document.write("<li>"); document.write(objname+'['+i+'] = '+obj[i]); if(typeof(obj[i]) == 'object' || typeof(obj[i]) == 'array'){ document.write('<b style="font-size:13px;cursor:pointer;" mce_style="font-size:13px;cursor:pointer;" onclick="if(this.textContent==/'[展开]/'){this.textContent=/'[折叠]/';this.nextSibling.style.display=/'block/';}else{this.textContent=/'[展开]/';this.nextSibling.style.display=/'none/';}">[折叠]</b>'); vardump(obj[i],objname+"["+i+"]",deep); } document.write("</li>"); } document.writeln('</ul>'); }
