HTML 中 href、src 区别

阅读更多关于 HTML 中 href、src 区别

HTML 中 href、src 区别@ TOC href 是 Hypertext Reference 的缩写，表示超文本引用。用来建立当前元素和文档之间的链接。常用的有：link、a。例如： <link href="reset.css" rel=”stylesheet“/> 浏览器会识别该文档为 css 文档，并行下载该文档，并且不会停止对当前文档的处理。这也是建议使用 link，而不采用 @import 加载 css 的原因。 src 是 source 的缩写，src 的内容是页面必不可少的一部分，是引入。src 指向的内容会嵌入到文档中当前标签所在的位置。常用的有：img、script、iframe。例如: <script src="script.js"></script> 当浏览器解析到该元素时，会暂停浏览器的渲染，直到该资源加载完毕。这也是将js脚本放在底部而不是头部得原因。简而言之，src 用于替换当前元素；href 用于在当前文档和引用资源之间建立联系。来源： CSDN 作者： weixin_45760431 链接： https://blog.csdn.net/weixin_45760431/article/details/103613702

阅读更多关于 webkit / Chrome history.back(-1) onclick vs href

问题 Everybody knows that but I'll repeat the problem: <a href="#" onClick="history.go(-1)">Back</a> Will not work in WebKit based browsers (Chrome, Safari, Mxthon, etc.) Another approach (should work) that won't work is: <a href="#" onclick="javascript:window.history.back(-1);">Back</a> You could do this - works! (but that's showing JS in url hint) <a href="javascript:window.history.back(-1);">Back</a> To use JS in onclick event you could do this (works, but see comments below): <a onclick=

dc.js permalink or href to share the visualisation filter state?

阅读更多关于 dc.js permalink or href to share the visualisation filter state?

问题 I am working on a dataviz with dc.js (http://edouard-legoupil.github.io/3W-Dashboard/) The main limitation is that when users find a specific fact while they explore the data, it is not easy to reproduce the exact filters they used in order to share their findings with other users (and initiate a discussion). A solution could be to have permalinks for each filter state. dc.js has already the "dc.redrawAll();" to reset all filter but is there any capacity to freeze a certain filters state and

how to use the href attribute in django templates

阅读更多关于 how to use the href attribute in django templates

问题 When I try to use a link in my Django template from /appname/index/ to get to /appname/detail/### I am instead getting to /appname/index/detail/### which is not what I'm trying to get so my app can't find it in the urlconf of course.

问题 I found applying the following function to a links onclose works to close Fancybox from within an iFrame: parent.$.fancybox.close(); I want to take this further and have the link take the parent page to a new url. I've tried the following but it doesn't work: <a onclick="location.href='http://www.domain.com/page/';parent.$.fancybox.close();"> Close and go to page</a> using a href doesn't work either as the onclose takes precedence. 回答1: Very simple solution... can't believe I didn't think of
