var toUrl = 'saveNews.php';
var method = 'POST';
var paramSerial = 'name1=value1&name2=value2&name3=value3';

jQuery使用utf8.所以提交中文需要用到escape（都是utf-8就不用了）
var toUrl = 'saveNews.php';
var method = 'POST';
var paramSerial = 'name1=' + escape('value1') + '&name2=' + escape('value2');
$.ajax({
type: method,
url: toUrl,
data: paramSerial
});
