问题 I've used DomDocument to to GetElementById. It has selected a div. I need to replace all the header tags within that div with the h4 tag. 回答1: You have not made clear in your question what the concrete problem is you run into.

Javascript createElement no end tag

由 牧云@^-^@ 提交于 2019-12-30 10:00:13
问题 I'm trying to use document.createElement('circle') to work with svgs but Chrome creates a end tag to circle giving <circle></circle> which results of an error. How can I create an element without an ending that? 回答1: You might want to take a look at this article SVG Scripting with JavaScript Part 1: Simple Circle The method you're looking for is: var circle = document.createElementNS("http://www.w3.org/2000/svg", "circle"); Edit: Credit where credit is due Stackoverflow: Creating SVG graphics

问题 Is there a flash based document viewer? I am looking for something similar to iPaper that Scribd.com uses. 回答1: There's a great open source viewer for PDF2SWF: http://www.devaldi.com/?page_id=260 回答2: I've used PDF2SWF in the past to do basic document conversion/viewing in Flash: http://www.swftools.org/pdf2swf.html although I don't think they are as full featured as the iPaper and Scribd viewers - although it is entirely free to use. You can download from here: http://www.swftools.org

Create a DOM document from string, without JQuery

由 故事扮演 提交于 2019-12-28 12:17:42
问题 We're looking for ways to create a DOM document in javascript from a string, but without using Jquery. Is there a way to do so? [I would assume so, since Jquery can do it!] For those curious, we can't use Jquery, becase we're doing this in the context of a Chrome application's content script, and using Jquery would just make our content script too heavy. 回答1: In case you're still looking for an anwer, and for anyone else coming accross it, I just have been trying to do the same thing myself.
