如何在浏览器刷新上加载特定的页面
我有一个HTML页面，当按下“ Reset ”button时，我总是加载一个特定的页面（ control.html ）。
我不想要Resetbutton，而是在浏览器刷新时执行相同的操作。
我怎么做？ 似乎没有浏览器刷新的键码在整个浏览器中是通用的。 另外这个post是没有帮助的。
我正在使用一个nodejs服务器。 服务器代码如下：
var http = require('http'); var fs = require('fs'); var url = require("url"); var path = require("path"); var ent = require('ent'); //below creates the server functionality. //You shouldn't need to change this. var server = http.createServer(function(request, response) { var uri = url.parse(request.url).pathname , filename = path.join(process.cwd(), uri); var contentTypesByExtension = { '.html': "text/html", '.css': "text/css", '.js': "text/javascript", '.jpg': "image/jpeg", '.png': "image/png" }; //deal with post requests: if (request.method == 'POST') { var body = ''; request.on('data', function (data) { body += data; // Too much POST data, kill the connection! if (body.length > 1e6) request.connection.destroy(); }); request.on('end', function () { try { var post = JSON.parse(body); deal_with_post_data(request,post); response.writeHead(200, {"Content-Type": "text/plain"}); response.end(); return; }catch (err){ response.writeHead(500, {"Content-Type": "text/plain"}); response.write("Bad Post Data. Is your data a proper JSON?\n"); response.end(); return; } }); } //grab out REST requests and handle those, otherwise work as a normal file server. else if(uri=='/rest'){ try { rest_request(url.parse(request.url,true).query); response.writeHead(200, {"Content-Type": "text/plain"}); response.end(); return; }catch (err){ response.writeHead(500, {"Content-Type": "text/plain"}); response.write("Bad REST request.\n"); response.end(); return; } }else{ //return an error if a page is requested that does not exist. fs.exists(filename, function(exists) { if(!exists) { response.writeHead(404, {"Content-Type": "text/plain"}); response.write("404 Not Found\n"); response.end(); return; } //by default, if no page is requested, serve index.html if (fs.statSync(filename).isDirectory()) filename += '/index.html'; //read the requested file and serve it up. fs.readFile(filename, "binary", function(err, file) { if(err) { response.writeHead(500, {"Content-Type": "text/plain"}); response.write(err + "\n"); response.end(); return; } var headers = {}; var contentType = contentTypesByExtension[path.extname(filename)]; if (contentType) headers["Content-Type"] = contentType; response.writeHead(200, headers); response.write(file, "binary"); response.end(); }); }); } }); // Loading socket.io var io = require('socket.io').listen(server); io.sockets.on('connection', function (socket) { // When a "message" is received (click on the button), it's logged in the console socket.on('message', function (message) { console.log(' Received:' + message); socket.broadcast.emit('C', message); }); socket.on('wrong', function (message) { console.log(' Received:' + message); //signal all the clients there were some malicious attempts socket.broadcast.emit('W', message); }); //messages related to GT socket.on('messageGT', function (message) { console.log(' Received:' + message); socket.broadcast.emit('mGT', message); }); socket.on('wrongGT', function (message) { console.log(' Received:' + message); //signal all the clients there were some malicious attempts in GT socket.broadcast.emit('wGT', message); }); }); server.listen(8080);
刷新基本上是页面加载。
所以，如果你需要页面加载处理程序：
document.addEventListener('DOMContentLoaded', function(e) { // your reset button handler here });
或者，如果您需要页面离开：
document.addEventListener('onbeforeunload', function(e) { // your reset button handler here });
