正则表达式

Posted 2022-12-09 viana37

看完下面这个例子，估计正则表达式你就记起来了，而且能举一反三。

function a(url)
	var parse_url = /^(?:([A-Za-z]+):)?(\\/0,3)([0-9.\\-A-Za-z]+)(?::(\\d+))?(?:\\/([^?#]*))?(?:\\?([^#]*))?(?:#(.*))?$/;
	 
	var result = parse_url.exec(url);
	var names = ['url','scheme','slash','host','port','path','query','hash'];
	var blanks = '            ';
	var i;

	   for(i = 0; i < names.length; i++)
	
		document.write(names[i] + ':' + blanks.substring(names[i].length), result[i] + '<br/>');
	
	
	a('http:///www.ora.com:80/goodparts?q#fragment');
