JS_常用处理函数

 

１.ＰＨＰ时间戳转换

 

/*转换时间，计算差值*/ function comptime(beginTime,endTime){ var secondNum = parseInt(((new Date).getTime()-beginTime*1000)/1000);//计算时间戳差值 if(secondNum>=0&&secondNum<60){ return secondNum+'秒前'; } else if (secondNum>=60&&secondNum<3600){ var nTime=parseInt(secondNum/60); return nTime+'分钟前'; } else if (secondNum>=3600&&secondNum<3600*24){ var nTime=parseInt(secondNum/3600); return nTime+'小时前'; } else{ var nTime = parseInt(secondNum/86400); return nTime+'天前'; } } t = comptime(timestamp);//timestamp为PHP通过ajax回传的时间戳

 

2.格式化URL对象内容

 

function parseURL(url) { var a = document.createElement('a'); a.href = url; return { source: url, protocol: a.protocol.replace(':',''), host: a.hostname, port: a.port, query: a.search, params: (function(){ var ret = {}, seg = a.search.replace(/^/?/,'').split('&'), len = seg.length, i = 0, s; for (;i<len;i++) { if (!seg[i]) { continue; } s = seg[i].split('='); ret[s[0]] = s[1]; } return ret; })(), file: (a.pathname.match(///([^//?#]+)$/i) || [,''])[1], hash: a.hash.replace('#',''), path: a.pathname.replace(/^([^//])/,'/$1'), relative: (a.href.match(/tps?:////[^//]+(.+)/) || [,''])[1], segments: a.pathname.replace(/^///,'').split('/') }; } //用法 var myURL = parseURL('http://abc.com:8080/dir/index.html?id=255&m=hello#top'); myURL.file; // = 'index.html' myURL.hash; // = 'top' myURL.host; // = 'abc.com' myURL.query; // = '?id=255&m=hello' myURL.params; // = Object = { id: 255, m: hello } myURL.path; // = '/dir/index.html' myURL.segments; // = Array = ['dir', 'index.html'] myURL.port; // = '8080' myURL.protocol; // = 'http' myURL.source; // = 'http://abc.com:8080/dir/index.html?id=255&m=hello#top'
