新浪微博中的广告虽说不多，但是看着不舒服。写了个chrome插件去除了一部分，代码如下：
manifest.json：
{
"name": "clear taobao from weibo",
"version": "1.0",
"manifest_version": 2,
"description": "clear taobao from weibo",
"permissions": [ "http://weibo.com/*"],
"content_scripts": [ {
"all_frames": true,
"exclude_globs": [ ],
"exclude_matches": [ ],
"include_globs": [ ],
"js": ["help.js"],
"matches": [ "http://weibo.com/*"],
"run_at": "document_idle"
} ]
}
help.js：
function withjQuery(callback, safe) {
if (typeof (jQuery) == "undefined") {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://img3.douban.com/js/packed_jquery.min9556435062.js";
if (safe) {
var cb = document.createElement("script");
cb.type = "text/javascript";
cb.textContent = "jQuery.noConflict();(" + callback.toString()
+ ")(jQuery, window);";
script.addEventListener('load', function() {
document.head.appendChild(cb);
});
} else {
var dollar = undefined;
if (typeof ($) != "undefined")
dollar = $;
script.addEventListener('load', function() {
jQuery.noConflict();
$ = dollar;
callback(jQuery, window);
});
}
document.head.appendChild(script);
} else {
setTimeout(function() {
// Firefox supports
callback(jQuery, typeof unsafeWindow === "undefined" ? window
: unsafeWindow);
}, 30);
}
}
// 要进行的操作
withjQuery(
function($, window) {
$('div[ad-data^="id=ads_"]').attr('ad-data', '');
}, true);
