本文基于 SyntaxHighlighter 3.0.83 (July 02 2010)
工作需要简单的定制一下SyntaxHighlighter,在代码块首行显示代码的编程语言名.
效果:
重点:
SyntaxHighlighter.toolbar.items.list此变量存放需要toolbar元素,默认有['expandSource', 'help']- 自定义toolbar元素可以参加官方的expandSource元素实现,主要要实现getHtml或execute方法.
- getHtml返回值将会添加到页面
div.toolbar里 - execute用于点击getHtml返回Html所执行的代码
- 没有getHtml方法时,将会调用defaultGetHtml要方法
- getHtml返回值将会添加到页面
官方的expandSource代码
expandSource: {
getHtml: function(highlighter) {
if (highlighter.getParam('collapse') != true) return '';
var title = highlighter.getParam('title');
return sh.toolbar.getButtonHtml(highlighter, 'expandSource', title ? title : sh.config.strings.expandSource);
},
execute: function(highlighter) {
var div = getHighlighterDivById(highlighter.id);
removeClass(div, 'collapsed');
}
}
如果有用到jQuery,把调用SyntaxHighlighter.all();你改成SyntaxHighlighter.highlight();应该是更好的选择,因为默认SyntaxHighlighter.all();是需要用的是window.onload,要等页面和图片都加载完才会调用SyntaxHighlighter.highlight();高亮;你可以改用$.ready
如果需要高亮页面后生成的html,也只要调用SyntaxHighlighter.highlight();即可
实现代码:
//自定义配置
function my_syntax_highlighter() {
SyntaxHighlighter.config.stripBrs = true;
SyntaxHighlighter.config.useScriptTags = false;
SyntaxHighlighter.defaults.toolbar = true;
SyntaxHighlighter.highlight();
}
//统一显示代码名,而不是显示brush name短名称

if (result === null) return brush_name;

function custom_syntax_highlighter_toolbar() {

SyntaxHighlighter.toolbar.items.codeName = {
