dojo

I have a dijit.form.Select widget. It's tied to a data store, if that matters. It's filled with several options already. All I want to do is programmatically set its value. I can get its value using myWidget.attr('value') but if I try to do myWidget.attr('value', 5) for example (where 5 is one of the valid values), all it does is reset the widget to select the very first option, no matter what value I give it. This seems to be a bug, and there aren't any tests or documentation which show how to accomplish what I want to. But is there some way, even if it's a dirty hack? I'm using Dojo 1.4.0.

I have a simple Dojo application, that does only one require call, loading all the dependencies. The trouble is, while it is extremely simple, it still ends up loading ~100 files from server. I tried to solve that problem using Dojo build system, but seems I don't have a deep enough understanding. So my question is - given a list of dependencies, like the following: ["dojo/parser", "dijit/registry", "dojo/dom", "dojo/on", "dojo/query", "dojo/dom-class", "dojo/request", "dijit/form/ValidationTextBox", "dijit/form/Select", "dijit/form/NumberSpinner", "dijit/form/CheckBox", "dijit/layout

The Problem JSFiddle : http://jsfiddle.net/missingno/Gz8Pe/2/ I have some code that looks like this: var d = new Deferred(); d.resolve(17); return d.then(function(){ //do some stuff... }) .then(function(){ var obj = a_funtion_that_returns_null_on_IE(); var x = obj.some_property; //BOOM! }); The problem is that when I am on IE all I can see are 'obj' is null or not an object errors, without any reference to the corresponding line number and without the debugger halting at the offending line (like I wish it would). This kind of issue is making the code a pain to debug and the only solutions I

ArcGIS for javascript开发心得 本次实例中采用ArcGIS for javascript3.24版本，由于版本3与4在API等存在较大区别，就不一一列举，详细区别看 官方解释 arcgis for js4.7版本能够自动创建layer、graphs等类，而不像3.24版本需要在图形渲染前重新new 新的类。然而，查找大量文件资料，网上有关ArcGIS forjavascript的资料甚少，更不用说通过vueJS+arcGIS开发出一套可视化平台，在不断查看官方文档和实际操作,总结自己的构思和使用心得。 技术采用： vueJS + vuetify + axios + arcGIS3.24 + echarts 如图所示：可视化界面采用三层三文治结构，从server（后台，非online server）读取数据，vueJS负责数据驱动，ArcGIS与echarts负责数据的图形化。同时引入浏览器的web sql db本地数据库进行海量数据缓存 ArcGIS API for Javascript 是由美国 Esri 公司推出， 基于 dojo框架和 REST 格式的一套编程接口（目前最新版本为 3.3， dojo1.8。 通过 ArcGIS API for Javascript可以对 ArcGIS for Server 进行访问调用，并将 ArcGIS for

I'm looking for a neat way to detect whether postMessage in the browser supports the sending and receiving of objects or just strings. I figure that someone out there must have wrote something that does this but I have not managed to find a solution. I'm using postMessage to send data to/from a WebWorker. Whilst detecting whether the browser supports workers is straight-forward, detecting whether objects can be send via postMessage has proved more difficult. I'd like to write a simple detection function. So, if the browser supports the sending of objects to use that. If only strings are

1. 先在官网上ArcGIS API for JavaScript download page（需要有账户）下载最新的API：arcgis_js_v26_api.zip（ 点击直接下载 ）和 SDK: arcgis_js_v26_sdk.zip（ 直接下载 ）； 2. 将下载下来的 arcgis_js_v26_api.zip 和 arcgis_js_v26_sdk.zip 分别解压，将各自文件夹下的的 arcgis_js_api 文件夹拷贝到 C:\inetpub\wwwroot 下，因为拷贝的文件夹名称都为arcgis_js_api，因此当拷贝第二个文件夹时选择覆盖即可； 3. 将 C:\inetpub\wwwroot\arcgis_js_api\library\2.6\jsapi\js\esri 下的 esri.js 文件 C:\inetpub\wwwroot\arcgis_js_api\library\2.6\jsapi\js\dojo\dojo 下的 dojo.xd.js 及 dojo.xd.js.uncompressed.js 两个文件 中的 "[HOSTNAME_AND_PATH_TO_JSAPI] 替换为 djConfig.url + "/arcgis_js_api/library/2.6/jsapi/ （注意别少了冒号） 同理将 C:\inetpub\wwwroot
