I am using ArcGIS 3.5 Javascript API and RequireJS I implemented it using this code: <script> var map; require(["esri/map", "dojo/domReady!"], function(Map) { map = new Map("mapDiv", { center: [-96.571541, 39.155622], zoom: 3, basemap: "streets" }); }); }); </script> with this RequireJS Configuration : requirejs.config({ baseUrl: "js/",

I'm currently building a Markdown editor for the web. Markdown tags are previewed in realtime by appending their HTML equivalents via the Range interface. Following code is used, which should be working according to MDN: var range = document.createRange() var selection = window.getSelection() range.setStart(textNode, start) range.setEnd(textNode, end + 2) surroundingElement = document.cr
我目前正在为网络构建一个Markdown编辑器。 Markdown标签可以通过Range界面附加HTML代码实时预览。 以下代码被使用，应该按照MDN工作： var range = document.createRange() var selection = window.getSelection() range.setStart(textNode, start) range.setEnd(textNode, end + 2) surroundingElement = document.createElement('strong') range.surroundContents(surroundingElement) var cursorRange = document.creat
Is there a better way to engineer a sleep in JavaScript than the following pausecomp function (taken from here)? function pausecomp(millis) { var date = new Date(); var curDate = null; do { curDate = new Date(); } while(curDate-date < millis); } This is not a duplicate of Sleep in JavaScript - delay between actions; I want a real sleep in the middle of a function, and not a
有没有更好的方法来设计一个sleep JavaScript比下面的pausecomp函数（从这里取得）？ function pausecomp(millis) { var date = new Date(); var curDate = null; do { curDate = new Date(); } while(curDate-date < millis); } 这不是JavaScript中Sleep的重复 - 动作之间的延迟; 我想在函数中间进行真正的睡眠，而不是执行一段代码之前的延迟。 2017更新 自2009年问这个问题以来，JavaScript已经发
Assuming I have a div that looks like: <div id="testDiv">some stuff in here</div> and I have a script that defines an object literal: var testObject = { testDiv: $("#testDiv"), testDivProperty: this.testDiv }; Why is it when I access testObject.testDiv I get a reference to a jQuery object, ie, [<div id="testDiv">…</div>] but when I access testObject.
假设我有一个div ，如下所示： <div id="testDiv">some stuff in here</div> 我有一个定义对象文字的脚本： var testObject = { testDiv: $("#testDiv"), testDivProperty: this.testDiv }; 为什么当我访问testObject.testDiv我得到一个jQuery对象的引用，即， [<div id="testDiv">…</div>] 但是当我访问testObject.testDivProperty我得到了对实际元素的引用，即， <div id=
How to check if variable contains valid UUID/GUID identifier ? I'm currently interested only in validating types 1 and 4, but it's not limit for your answer. Currently, UUID's are as specified in RFC4122. Therefore to validate a UUID... /^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i ...ensures you have a canonically formatted UUID that is Version
如何检查变量是否包含有效的UUID / GUID标识符？ 我目前只对验证类型1和4感兴趣，但对答案没有限制。 目前，UUID与RFC4122中的规定相同。 因此要验证UUID ... /^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i ...确保您具有版本1至5的标准格式的UUID，并且是根据RFC4122的相应Variant。 注：大括号“{”和“}”不是规范的。 它们是一些系统和用法的产物。 易于修改上述正则表达式以满足
