JS用JSON作为参数

function getAjaxData(urlstr, callback_func, options){
var myurl = AJAX_HEADER + urlstr + AJAX_TAIL;
var isAsync = true;//初始化是否同步的属性设置
var nTimeout = AJAX_TIMEOUT;//初始化请求超时的数据
var errorCallback = null;
//利用JSON对象options来修改默认初始化的属性，这样一个参数可以设置多个属性
if (options)
{
if (options.sync)         	//sync这个参数就是JSON的对象
{
isAsync = (options.sync === true) ? false : true;
}
if (options.timeout)
{
nTimeout = parseInt(options.timeout);
if (isNaN(nTimeout))
nTimeout = AJAX_TIMEOUT;
}
errorCallback = options.errorCB;
}
