使用 fs 模块创建可读流：

var http = require('http');
var fs = require('fs');

var server = http.createServer(function (req, res) {
    var stream = fs.createReadStream(__dirname + '/data.txt');
    stream.pipe(res);
});
server.listen(8000);

并通过流模块实例化它：

var Readable = require('stream').Readable;

var rs = new Readable;
rs.push('file.txt');
rs.push('boop\n');
rs.push(null);

rs.pipe(process.stdout);

我无法在 Chrome 52.0 中使用此 CORS 解决方法。我的 iframe 和父页面位于不同的子域上。

我的 iframe 的事件监听器：

window.onload = function () {
    window.addEventListener("message", function(event) {
       //doesn't log it
       console.log('message');
       if(event.data === "invokeChildFunction()") {
           childFunction();
       }
    });
    function childFunction() {
        alert('Parent frame just invoked my function')
    }
}

父框架：

var iframeWindow = $('iframe').contentWindow;
var invokeChildFunction = function () {
  iframeWindow.postMessage("invokeChildFunction()", "https://mansion-assessment-sdimoff.c9users.io/CORS/index.html");
}

invokeChildFunction()不在 iframe 页面记录任何内容

我试图围绕git冲突,为什么合并这两个会导致冲突？

分支上的file.txt master:

This is line number one

分支上的file.txt feature:

This is line number one
This is line number two

我很难理解代码的第一部分.我不明白我们追求的combine功能.还有什么办法thisOneCounts？真的,我没有评论的任何事我都不明白.

//count the ancestors over 70
function countAncestors(person, test) {
    //supposed to combine parents recursively
    function combine(person, fromMother, fromFather) {
        //stores people over 70
        var thisOneCounts = test(person);
        //if the person passed the `test` (>70), then 1 is included
        return fromMother + fromFather + (thisOneCounts ? 1 : 0);
    }
    return reduceAncestors(person, combine, 0);
}

//find the percentage of known ancestors, who lived > 70 years
function longLivingPercentage(person) {
    var all = countAncestors(person, function(person) {
        return …

我想添加tres4数组中所有字符串的相应索引,如果它们匹配输入字符串的结尾.然而,我的列表中填充了所有索引1-12,而不是仅匹配输入字符串末尾的那些索引.在这种情况下,只1应该添加到我的List.
