在JS中序列化JSON

SerializeJsonToStr : function( oJson )
{
if( oJson == null )
return "null";
if( typeof(oJson) == typeof(0) )
return oJson.toString();
if( typeof(oJson) == typeof('') ||
oJson instanceof String )
{
oJson = oJson.toString();
oJson = oJson.replace( //r/n/, '//r//n');
oJson = oJson.replace( //n/, '//n');
oJson = oJson.replace( //"/, '//"');
return '"' + oJson + '"';
}
if( oJson instanceof Array )
{
var strRet = "[";
for( var i = 0; i < oJson.length; i++)
{
if( strRet.length > 1 )
strRet += ",";
strRet += ExternalInterface.SerializeJsonToStr(oJson[i]);
}
strRet += "]";
return strRet;
}
if( typeof(oJson) == typeof({}) )
{
var strRet = "{";
for( var p in oJson )
{
if( strRet.length > 1 )
strRet += ",";
strRet += p.toString() + ':' + ExternalInterface.SerializeJsonToStr(oJson[p]);
}
strRet += "}";
return strRet;
}
}
