javascript中将Object转换为String函数代码 (json str)
本文介绍了JavaScript中如何将Object转换为String函数，详细的代码如下文所示：
代码如下:
function obj2str(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+":"+obj2str(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(obj2str(o[i]))
r="["+r.join()+"]"
}
return r;
}
return o.toString();
} 利用原生JSON对象，将对象转为字符串
[javascript]
- var jsObj = {};
- jsObj.testArray = [1,2,3,4,5];
- jsObj.name = 'CSS3';
- jsObj.date = '8 May, 2011';
- var str = JSON.stringify(jsObj);
- alert(str);
从JSON字符串转为对象
[javascript]
- var jsObj = {};
- jsObj.testArray = [1,2,3,4,5];
- jsObj.name = 'CSS3';
- jsObj.date = '8 May, 2011';
- var str = JSON.stringify(jsObj);
- var str1 = JSON.parse(str);
- alert(str1);
