A friend of mine got bitten by the all too famous 'anonymous functions in loop' javascript issues. (It's been explained to death on SO, and I'm actually expecting someone to my question as a duplicate, which would probably be fair game). The issue amounts to what John Resig explained in this tutorial : http://ejohn.org/apps/learn/#62 var count = 0; for ( var i = 0; i < 4
我的一位朋友被所有过于着名的'循环'javascript问题中的匿名函数所困扰。 （它已被解释为死亡，我实际上期待有人把我的问题视为重复，这可能是公平的游戏）。 这个问题相当于John Resig在本教程中解释的内容： http://ejohn.org/apps/learn/#62 var count = 0; for ( var i = 0; i < 4; i++ ) { setTimeout(function(){ assert( i == count++, "Check the value of i." ); }, i * 200); } 对于一
I have two web page(a.php & b.php). They have very similar logic but distinct UI. I wrote two javascript. They both look like: aUI = { displayMessage = function ... showDetails = function ... } function foo() { aUI.displayMessage(); aUI.showDetails(); // and other things about aUI.displayMessage() and aUI.showDetails()... } foo(); aUI.displayMessage() is different
我有两个网页（a.php＆b.php）。 他们有非常相似的逻辑，但不同的UI。 我写了两个JavaScript。 他们都是这样的： aUI = { displayMessage = function ... showDetails = function ... } function foo() { aUI.displayMessage(); aUI.showDetails(); // and other things about aUI.displayMessage() and aUI.showDetails()... } foo(); aUI.displayMessage（）与bUI.displayMessage（）不同。 但
I have an object: myObject = { 'a': 1, 'b': 2, 'c': 3 } I am looking for a native method, similar to Array.prototype.map that would be used as follows: newObject = myObject.map(function (value, label) { return value * value; }); // newObject is now { 'a': 1, 'b': 4, 'c': 9 } Does JavaScript have such a map function for objects? (I want this for Node.JS, so I don't care about cross-b
我有一个对象： myObject = { 'a': 1, 'b': 2, 'c': 3 } 我正在寻找一个本地方法，类似于Array.prototype.map ，它的使用方法如下： newObject = myObject.map(function (value, label) { return value * value; }); // newObject is now { 'a': 1, 'b': 4, 'c': 9 } JavaScript是否具有这种对象的map功能？ （我想要Node.JS，所以我不在乎跨浏览器的问题。） 没有本地map到Object对象，但是这个如何： Object.keys(
Does anybody know of a script that will let me diplay image results in the way that Google Image Search does (image grid view) with hover to enlarge and details? Something that I can just "plug-and-play" so to speak. 看看砌体http://masonry.desandro.com/ First, you need to put all images inside a container element: <div class="parent"> <img src=""> <img src=""&
是否有人知道一个脚本，它可以让我以Google图片搜索的方式显示图片结果（图片网格视图），并将鼠标悬停为放大和细节？ 一些我可以“即插即用”的东西可以这么说。 看看砌体http://masonry.desandro.com/ 首先，您需要将所有图像放入容器元素中： <div class="parent"> <img src=""> <img src=""> <img src=""> </div> 然后你需要确保图像显示在一行中。 这可以通过例如float: lef
I'm trying to make a generic javascript dialog-class based on JQuery to create div-popups centered on the screen. Achieving this in all the common browsers was plain vanilla. For mobile platforms, the issue of the viewport arises; the difference of the visible viewport (which is your current "viewing window" of the site as you see it, zoomed in or not) and the layout viewport (t
我试图制作一个基于JQuery的通用JavaScript对话框类来创建屏幕上居中的div-popups。 在所有常见的浏览器中实现这一点是普通的香草。 对于移动平台而言，出现了视口问题; 可见视口（这是您当前看到的，放大或缩小的网站的“查看窗口”）和布局视口（底层页面的尺寸，换句话说，CSS视口）之间的差异。 对于Iphone，我已经能够使用DOM属性window.innerWidth和window.innerHeight来调整缩放的居中，pageXOffset / pageYOffset用
I'm trying to work with Jquery and Svg together. But I don´t want to use any plugin. The problem I am dealing now is that when I try to work using the traditional append mode to add a child to the svg document, the object is not rendered. Let´s check out what I tried to do: /* Creating the svg container using pure JS */ var container = document.getElementById("svg_space"); mySvg = docume
我正在尝试与Jquery和Svg一起工作。 但我不想使用任何插件。 我现在处理的问题是，当我尝试使用传统的追加模式向svg文档添加子项时，该对象未呈现。 让我们看看我试图做的事情： /* Creating the svg container using pure JS */ var container = document.getElementById("svg_space"); mySvg = document.createElementNS("http://www.w3.org/2000/svg", "svg"); mySvg.setAttribute("version", "1.2"); mySvg.setAttribute

I put together a plugin for an app some months ago with phonegap 2.7 and it worked perfectly. The plugin basically opens up the users phonebook and returns to my app the details of the contact the user selects. I have recently upgraded to Phonegap 3.0 and I am trying to convert my plugin to 3.0; However I can't get the plugin to work now that it's all 3.0....here is what I have Cont
