function writeObj(obj){
var description = "";
for(var i in obj){
var property=obj[i];
description+=i+" = "+property+"\n";
}
console.log("obj:"+description);
}
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
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();
} 獲取value的值： var mes= document.getElementById(‘mes‘);
for(i in pstrWord ){
alert(i); //獲得屬性
alert(pstrWord[i]); //獲得屬性值
}
1、js輸出object對象方法如下：
function writeObj(obj){
var description = "";
for(var i in obj){
var property=obj[i];
description+=i+" = "+property+"\n";
}
console.log("obj:"+description);
}
2、object對象轉換為string字符串方法如下：
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
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();
} 獲取value的值： var mes= document.getElementById(‘mes‘);
