如果我有这样的表：
<td class="search-unit-custom-control-calendar-day search-unit-custom-control-calendar-day--not-this-month">
<time class="search-unit-custom-control-calendar-day__number">--</time>
</td>
<td class="search-unit-custom-control-calendar-day search-unit-custom-control-calendar-day--unavailable">
<time class="search-unit-custom-control-calendar-day__number">--</time>
</td>
<td class="search-unit-custom-control-calendar-day search-unit-custom-control-calendar-day">
<time class="search-unit-custom-control-calendar-day__number">--</time>
</td>
<td class="search-unit-custom-control-calendar-day search-unit-custom-control-calendar-day">
<time class="search-unit-custom-control-calendar-day__number">--</time>
</td>
<td class="search-unit-custom-control-calendar-day search-unit-custom-control-calendar-day">
<time class="search-unit-custom-control-calendar-day__number">--</time>
</td>
如何选择可用日期，例如：
`tbody.search-unit-custom-control-calendar__table__page tr td[class*=calendar-day-]:not([class*='unavailable'] && [class*='--not-this-month']))`
当我使用它时它不起作用，有人可以帮忙吗？

我认为您只需要添加第二个:not条件，而不是将它们与&&连接起来。
像这样：
tbody.search-unit-custom-control-calendar__table__page tr td[class*=calendar-day]:not([class*='unavailable']):not([class*='--not-this-month'])

css选择器不正确，父选择器var app = require("express")();
var express = require("express");
var server = require("http").Server(app);
var p2pserver = require("socket.io-p2p-server").Server;
var io = require("socket.io")(server);
var ss = require("socket.io-stream");
var path = require("path");
app.use(express.static(__dirname));
io.use(p2pserver);
var peerNum = 0;
io.on("connection", function(socket) {
console.log("Peer " + peerNum + " connected");
io.emit("peer-num", peerNum);
peerNum++;
ss(socket).on("file", function(stream, data) {
var filename = path.basename(data.name);
var parts = [];
stream.on("data", function(data) {
parts.push(data);
});
stream.on("end", function() {
socket.broadcast.emit("file", parts);
});
});
});
server.listen(8080, function () {
console.log("Listening on 8080")
});
排除所有没有合成类的// Browserified
var P2P = require("socket.io-p2p");
var io = require("socket.io-client");
var ss = require("socket.io-stream");
var socket = io();
var opts = {autoUpgrade: true, peerOpts: {numClients: 10}};
var p2p = new P2P(socket, opts);
var $ = require("jquery");
p2p.on("peer-num", function(num) {
console.log("You are peer number " + num);
$(".peerNum").html( "Number " + num );
});
p2p.on("file", function(stream) {
console.log(stream);
var img = document.createElement("img");
img.src = (window.URL || window.webkitURL).createObjectURL(new Blob(stream));
document.getElementById("receivedImages").appendChild(img);
});
$(function() {
$("#file").change(function(e) {
ss.forceBase64 = true;
var file = e.target.files[0];
var stream = ss.createStream();
ss(socket).emit("file", stream, {size: file.size,name:file.name});
var blobStream = ss.createBlobReadStream(file);
var size = 0;
blobStream.on("data", function(chunk) {
size += chunk.length;
console.log(Math.floor(size / file.size * 100) + "%");
});
blobStream.pipe(stream);
});
});
（类名后没有破折号）所以它离开了排出最后四个细胞。请看this working example。
