What is “(program)” in Chrome debugger’s profiler?

什么是Chrome调试器功能列中的“(程序)”? (program) is Chrome itself, the root of the tree calling all other code...it's there because the jump from native code to JavaScript, resource loading, etc. has to start somewhere :) You can see examples of the treeview in the Chrome developer tool docs. I believe (program) is native code, not the root of the tree. See this thread: https://bugs

Chrome调试器的分析器中的“(程序)”是什么?

什么是Chrome调试器功能列中的“(程序)”? (program)是Chrome本身,调用所有其他代码的树的根...它在那里,因为从本地代码跳转到JavaScript,资源加载等必须从某处开始:) 您可以在Chrome开发人员工具文档中查看树视图的示例。 我相信(程序)是本地代码,而不是树的根。 看到这个主题: https://bugs.webkit.org/show_bug.cgi?id=88446 所以,比起main()更像系统调用。 显然它包括空闲时间。 另外,一些(程序)

Allow for zero

Short-circuit evaluation determines if the first value is falsey. If so, return the second value, as follows: var x = y || z; // if y is falsey return z Is there a way to disregard zero-values as being falsey when using short-circuit evaluation without resorting to if/else statements or ternary operators? 您可以将您的号码包裹到一个Number对象中并检查; var x = new Number(0) || console.log("neve

允许为零

短路评估确定第一个值是否有误。 如果是,则返回第二个值,如下所示: var x = y || z; // if y is falsey return z 如果不使用if / else语句或三元运算符进行短路评估,有没有办法忽略零值为假的? 您可以将您的号码包裹到一个Number对象中并检查; var x = new Number(0) || console.log("never gets printed"); console.log(parseInt(x)); //or console.log(x.valueOf()); 编辑: 如果z是一个数字,你可以使用这样的

How can I find the highest poker hand from a 9 card hand between 4 players?

I've tried to look through several sources online and they all deal with 5 card and 7 card hands. Also, I'm not really looking for the code, I'll try to do that on my own (although perhaps if you're willing, I'm looking to implement this in either Python or JavaScript). I just want someone to explain to me the steps involved in finding such a hand (using pseudocode). Basic

我如何从4名牌手之间的9张牌中找到最高的牌手?

我试图在网上查看几个来源,他们都处理5张牌和7张牌。 另外,我并没有真的在寻找代码,我会自己尝试这样做(尽管如果你愿意的话,我希望用Python或JavaScript来实现)。 我只是想让别人向我解释找到这样一只手的步骤(使用伪代码)。 基本上,我问的是:我怎样才能从9名牌手中找到4名选手中最高的牌手? 我是否应该将所有最高的扑克牌手数字分配到排名中,然后解析每个玩家的手牌并查看他们的手牌是否包含该数字? 这似乎

Expectimax Algorithm for 2048 Not Performing Expectation as Intended?

I wrote an Expectimax solver for 2048 using the heuristics noted on the top ranking SO post "Optimal AI for 2048". However, my expectimax algorithm performs maximization correctly but when it hits the expectation loop where it should be simulating all of the possible tile spawns for a move (90% 2, 10% 4) - it does not seem to function as intended. game2048.prototype.ai = function (th

2048年Expectimax算法不能达到预期目标?

我使用在排名最高的SO帖子“Optimisation AI for 2048”中提到的启发式方法编写了2048年的Expectimax求解器。 然而,我的expectimax算法正确地执行了最大化,但是当它达到预期循环时,它应该模拟一个移动的所有可能的tile产生(90%2,10%4) - 它似乎没有像预期的那样工作。 game2048.prototype.ai = function (theState, depth, playerOne, alpha) { var state = this.clone(theState); var moves = this.validMoves(

How to match and highlight all terms in any order from an array of strings?

The requirements are: Find strings from an array (from here on called options) that include ALL the terms in ANY order Correctly highlight the matching terms - ie. insert a string before and after each matching term - I'm using <u> and </u> here Both the search query and options can be "anything" For the sake of simplicity answers can concentrate on case-insensi

如何从字符串数组中按任何顺序匹配和突出显示所有术语?

要求是: 从数组中查找字符串(从这里称为选项),其中包含任何顺序的所有术语 正确突出显示匹配的术语 - 即。 在每个匹配词语前后插入一个字符串 - 我在这里使用<u>和</u> 搜索查询和选项都可以是“任何” 为了简单起见,答案可以专注于通过仅包括ASCII字符的列表进行不区分大小写的搜索,并假定术语分隔符是简单的空格 - 即。 作为“Foo bar baz”输入的查询意味着搜索条件是['foo', 'bar',

Most efficient way to calculate Fibonacci sequence in Javascript

I'm attempting to get better with optimizing algorithms and understanding big-o, etc. I threw together the below function to calculate the n-th Fibonacci number. This works (for a reasonably high input). My question is, how can I improve this function? What are the drawbacks of calculating the Fibonacci sequence this way? function fibo(n) { var i; var resultsArray = [];

最有效的方法来计算Javascript中的斐波那契数列

我正在尝试通过优化算法和理解big-o等方面做得更好。 我把下面的函数放在一起来计算第n个斐波那契数。 这有效(对于相当高的输入)。 我的问题是,我该如何改进这个功能? 用这种方法计算斐波纳契数列有什么缺点? function fibo(n) { var i; var resultsArray = []; for (i = 0; i <= n; i++) { if (i === 0) { resultsArray.push(0); } else if (i === 1) {

从iframe创建PDF文件

我想保存一个包含IFrame内容的PDF文件。 我正在使用jsPDF。 当我点击调用该函数的按钮时,该脚本创建一个空的PDF页面。 该框架的内容如下所示:https://jsfiddle.net/ss6780qn/ 我正在使用以下脚本: <script src="../jspdf/plugins/standard_fonts_metrics.js"></script> <script type="text/javascript"> function toPDF(){ var pdf = new jsPDF('p', 'in', 'letter'); // sourc

How can i update two slice with same silde in nrrd loader

I am new to Javascript and NRRD Loader , in nrrd loader we can change the index value of a slice using the slider sliceY = volume.extractSlice('y', Math.floor(volume.RASDimensions[1]/2)); scene3.add(sliceY.mesh); gui.add(sliceY, 'index', 0, volume.RASDimensions[1], 1).name('indexY').onChange(function () { sliceY.repaint.call(sliceY); }); Consider I need update value of slicesX at same time w

如何在nrrd加载器中使用相同的silde更新两个片

我是Javascript和NRRD Loader ,在nrrd loader中,我们可以使用滑块更改切片的索引值 sliceY = volume.extractSlice('y', Math.floor(volume.RASDimensions[1]/2)); scene3.add(sliceY.mesh); gui.add(sliceY, 'index', 0, volume.RASDimensions[1], 1).name('indexY').onChange(function () { sliceY.repaint.call(sliceY); }); 考虑我需要使用相同的滑块同时更新slicesX的值 sliceX = volume.extractSlice('x', Math.floo

How to stop clearQueue() from clearing in

I have a button, upon clicking on which a div is shown in 500ms and then after 500ms class shake is added onto that div. This shake classe is then removed after 2 seconds with delay . What I want is if user keep pressing on button then all callbacks become canceled except the last one. Problematic code if click is pressed many time: $("button").click(function() { $(".content").show({

如何阻止clearQueue()清除

我有一个按钮,点击哪个div显示在500毫秒,然后在500毫秒之后,类别摇动被添加到该div。 然后在2秒后delay删除此摇动类别。 我想要的是,如果用户一直按住按钮,那么除最后一个以外,所有回调都会被取消。 如果按下多次按下有问题的代码: $("button").click(function() { $(".content").show({ duration: 500, done: function() { $(".content").addClass("shake"); var time = parseFloat($(".
