小编ECM*_*ipt的帖子

当我试图在Jetbrains Webstorm中创建一个项目时,会创建一个名为的文件夹.idea.如果我删除它可以吗？它会影响我的项目吗？

我正在尝试为网站制作用户脚本以添加自定义表达.但是,我遇到了很多错误.

这是功能:

function saveEmotes() {
    removeLineBreaks();
    EmoteNameLines = EmoteName.value.split("\n");
    EmoteURLLines = EmoteURL.value.split("\n");
    EmoteUsageLines = EmoteUsage.value.split("\n");

    if (EmoteNameLines.length == EmoteURLLines.length && EmoteURLLines.length == EmoteUsageLines.length) {
        for (i = 0; i < EmoteURLLines.length; i++) {
            if (checkIMG(EmoteURLLines[i])) {
                localStorage.setItem("nameEmotes", JSON.stringify(EmoteNameLines));
                localStorage.setItem("urlEmotes", JSON.stringify(EmoteURLLines));
                localStorage.setItem("usageEmotes", JSON.stringify(EmoteUsageLines));
                if (i == 0) {
                    console.log(resetSlot());
                }
                emoteTab[2].innerHTML += '<span style="cursor:pointer;" onclick="appendEmote(\'' + EmoteUsageLines[i] + '\')"><img src="' + EmoteURLLines[i] + '" /></span>';
            } else {
                alert("The maximum emote(" + EmoteNameLines[i] + ") size is (36x36)");
            } …

操作系统:Ubuntu 16.04

Swift版本:3.0预览版6

我正在关注这个入门页面

在 greeter.swift

func sayHello(name: String) {
  print("Hello, \(name)!")
}

在 main.swift

if Process.arguments.count != 2 {
    print("Usage: hello NAME")
} else {
    let name = Process.arguments[1]
    SayHello(name: name)
}

我收到错误

我正在尝试添加一个锚标记，并在标记周围添加 URL。我不知道该怎么做，我已经被难住了好几个小时了..

给出这段代码时:

while(true){
 ...
}

可以异步执行多少次？

我已经写了这个来测试以及它如何与Google的JavaScript V8引擎交互,并且一次只有一个while循环处于活动状态.

var cycles = 0;
var counter = new Date();
var OpsStore = [];
var threads = [];

for(var i = 0; i < 10; i++){
  setTimeout(newThread(i),0);
}
function renew(){
    if (secondPassed(counter, new Date())){
        counter = new Date();
        Ops();
    }
    cycles++;
}

function newThread(id){
    threads.push({id: id, active: true});
    return function(){
        while(true){
            console.log(id);
            threads[id].active = true;
            renew();
        }
    }
}

    OpsStore.push(cycles);
    console.log(cycles, ' avg: ', getAvgOps());
    console.log(threads);
