DOJO和DIJIT不能两次分析相同的ID？ [英] DOJO and DIJIT can not parse same ID twice?

问题描述

我在使用DOJO时遇到问题，在这里我会动态地加载一些内容的div，然后运行parser.parse（dom.byId（mainDiv））;与各自的要求。而且第一次美妙地工作。然而，第二次，我最终遇到一个问题，它只显示内容不再被激活或风格。

在第二次运行我做的是删除所有的HTML在div中，然后用基本的未解析文本替换html，然后再次解析。现在我猜测它必须用dijit.registry做一些事情，但是我找不到确切的问题，因为我已经尝试清除这一点，也没有效果。您的帮助将不胜感激。

解决方案

Dojo会跟踪指定ID所创建的对象/小部件。如果你在同一个id的对象上再次运行解析器，dojo会尝试创建一个第二个实例，但是已经有一个实例，所以应该在你的js控制台中抛出一个错误（请检查）。

您可以将该ID留空，然后dojo / parse应为您创建一个ID。
Dojo允许您通过类属性找到dom元素，这样就可以将div元素传递给parse（）函数，而不给它一个明确的id。

另一方面是在再次解析div元素之前，摧毁创建的小部件/对象，看看这里：

I am having a problem while working with DOJO where I will dynamically load a div with some content and then run parser.parse(dom.byId("mainDiv")); with the respective requires. And that works beautifully the first time. The second time however I end up running into a problem where it just shows the content no longer activated or styled.

On a second run what I do is remove all the html in the div and then replace the html with basic unparsed text and then I parse it again. Now I am guessing it has to do something with dijit.registry however I can not find exactly what the issue is as I have tried clearing that out as well to no avail. Your help would be much appreciated.

解决方案

Dojo keeps track of the objects / widgets it creates by the specified id. If you run the parser again on an object with the same id, dojo tries to create a second instance, but there is already one, so it should throw an error in your js console (please check).

You could leave the id blank, then dojo / parse should create an id for you. Dojo allows you to find dom elements by class attributes, that way you could pass your div-element to the parse() function without giving it an explicit id.

Anotherway would be to destroy the created widget/object before you parse the div-element again, take a look here for that:

Quote from http://livedocs.dojotoolkit.org/dojo/parser#parse

"If you try to parse the same content twice, or parse content mentioning id's of existing widgets, it will cause an exception about duplicate id's"
