在开发一个页面的时候常常会有这么一个小功能，就是分享该页面中的信息。

常见的分享代码有百度分享， JiaThis分享插件，bshare分享插件等，我主要分享一下自定义分享代码，如下：

function dofristshare(type) {
var title = encodeURIComponent("新年快乐,马年吉祥");
var link = encodeURIComponent('http://www.baidu.com');
var image = encodeURIComponent('http://www.baidu.com/img/bdlogo.gif');

if (type == "sina") {
window.open("http://v.t.sina.com.cn/share/share.php?url=" + link + "&title=" + title + "&content=utf8&pic=" + image);
}

if (type == "tx") {
window.open("http://v.t.qq.com/share/share.php?url=" + link + "&title=" + title + "&pic=" + image);
}

if (type == "qzone") {

}

if (type == "rr") {
window.open("http://widget.renren.com/dialog/share?resourceUrl=" + link + "&title=" + title + "&pic=" + image);
}

if (type == "douban") {
window.open("http://www.douban.com/recommend/?url=" + link + "&title=" + title + "&image=" + image);
}

return false;

}
