Here's the problem: I have a form that is rendered with the Zend Framework form class, which has an ajax radio button selection. Clicking one of these radio buttons will send an ajax request to another controller, which has no layout, just a rendered form. The ajax request will then populate a div with the new form options. Problem is, when I replace the innerHTML of the div with the

Dojo version compatibility

问题 I started working on a web application that currently uses version 0.4. How would I go about upgrading to the latest version, 1.5? I don't think it's backward compatible? Would I make a sub-directory in the "js" dir, call it v1.5, and add new code using a new tag that references the new version? Then, over time, refactor the old code to use the new version? 回答1: There are a lot of changes from 0.4 to the current version (1.5). There used to be some porting guides available on the Dojo site,

arcgis for javascript之ArcGISDynamicMapServiceLayer图层控制的实现

阅读更多关于 arcgis for javascript之ArcGISDynamicMapServiceLayer图层控制的实现

图层控制是非常多GIS系统里面必须的一个小功能，本文就说说arcgis for javascript下ArcGISDynamicMapServiceLayer图层控制的实现方式。首先看图：实现效果重点有下面两点：1、获取ArcGISDynamicMapServiceLayer的图层；2、控制图层的显示。图层的获取可通过layerInfos实现，图层的显示通过setVisibleLayers实现，源码例如以下： <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"/> <title>Simple Map</title> <link rel="stylesheet" href="http://localhost/arcgis_js_api/library/3.9/3.9/js/esri/css/esri.css"> <style type="text/css"> @import "http://localhost/arcgis_js_api/library/3.9/3.9/js

上层建筑——DOM元素的特性与属性（dojo/dom-attr）

阅读更多关于上层建筑——DOM元素的特性与属性（dojo/dom-attr）

　　上一篇返本求源中，我们从DOM基础的角度出发，总结了特性与属性的关系。本文中，我们来看看dojo框架是如何处理特性与属性的。dojo框架中特性的处理位于dojo/dom-attr模块属性的处理为与dojo/dom-prop模块中。 attr.set（）　　方法的函数签名为： require(["dojo/dom-attr"], function(domAttr){ result = domAttr.set("myNode", "someAttr", "value"); }); 　　“someAttr”代表特性名称，但有时候也可以是一些特殊的属性名，如：‘textContent’：　　　　可以看到上图中使用attr设置innerText只会在html标签中增加innerText这个自定义特性，而无法改变文本，使用textContent却能够达到改变文本的目的。其中缘由就是因为在attr模块建立了forceProps字典，在此字典中的key全部使用prop模块来设置： forcePropNames = { innerHTML: 1, textContent:1, className: 1, htmlFor: has("ie"), value: 1 } 　　set（）方法中主要处理以下几件事： “someAttr”除了可以是字符串外，还可以是key-value对象
