prettify实现html页面黑色高亮代码

2017-06-18 阅读：2887 类型：后端分类：html 标签： html

头部引入prettify样式和js：

<link href="/public/static/index/css/prettify.css" rel="stylesheet">    
<!-- note_detail end -->    
<script src="/public/static/index/css/prettify.js"></script>

给body加onload="prettyPrint()"方法

<body onload="prettyPrint()">

底部script代码：

<script>    
window.onload = function ()    
{      
	prettyPrint();    
}    
$(function() {
  prettyPrint();
  $('pre').addClass("prettyprint linenums");
})     
</script>

效果：

var currentTime = Math.floor(parseInt(audio.currentTime)/60)+":"+(parseInt(audio.currentTime)%60/100).toFixed(2).slice(-2); 
    console.log(Math.floor(parseInt(currentTime)/60)+":"+(parseInt(currentTime)%60/100).toFixed(2).slice(-2));
    $("#current").html(currentTime);
}

pre标签代码换行样式：
