对象是object将其转化为字符串类型,然后就可以打印出来了:
- function obj2string(o){
- var r=[];
- if(typeof o=="string"){
- return "\""+o.replace(/([\'\"\\])/g,"\\$1").replace(/(\n)/g,"\\n").replace(/(\r)/g,"\\r").replace(/(\t)/g,"\\t")+"\"";
- }
- if(typeof o=="object"){
- if(!o.sort){
- for(var i in o){
- r.push(i+":"+obj2string(o[i]));
- }
- if(!!document.all&&!/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)){
- r.push("toString:"+o.toString.toString());
- }
- r="{"+r.join()+"}";
- }else{
- for(var i=0;i<o.length;i++){
- r.push(obj2string(o[i]))
- }
- r="["+r.join()+"]";
- }
- return r;
- }
- return o.toString();
- }
另外当你需要将object对象直接通过alert弹窗打印出来的时候,
- function writeObj(obj){
- var description = "";
- for(var i in obj){
- var property=obj[i];
- description+=i+" = "+property+"\n";
- }
- alert(description);
- }
