PhantomJSで指定したURLのHTMLに含まれる自ドメインのリンクリストを返却する

Last updated at Posted at 2014-07-17

filterはIE8だと利用できないです。

links.js
var  page = require('webpage').create()
	,system = require('system')
	,ua, url;

if (system.args.length != 3) {
	console.log('[Error] Invalid Argument...');
	phantom.exit();
} else {
	url = system.args[1];
	ua = system.args[2];
	
	page.settings.userAgent = ua;
	page.open(url, function (status) {
		if (status !== 'success') {
			console.log('[Error] Unable to load the [' + url + '] ...');
		} else {
			var ret = page.evaluate(function () {
				var aTag = document.links;
				var aTagList = [];
				var domain = location.href.match(/^[httpsfile]+:\/{2,3}([0-9a-z\.\-:]+?):?[0-9]*?\//i)[1];
				
				for (var i = 0, len = aTag.length; i < len; i++) {
					if (aTag[i].href.indexOf(domain) == -1) continue;
					aTagList.push(aTag[i].href);
				}
				
				var aTagUniqueList = aTagList.filter(function (x, index, self) {
					return self.indexOf(x) === index;
				});
				return aTagUniqueList.join("\n");
			});
			console.log(ret);
		}
		phantom.exit();
	});
}
