我有一个字符串数组和一个字符串.我想针对数组值测试此字符串并应用条件结果 - 如果数组包含字符串do"A",否则执行"B".
我怎样才能做到这一点？
我正在查看Mozilla的代码,它为Array添加了一个过滤方法,它有一行代码让我很困惑.
var len = this.length >>> 0;
我以前从未见过用于JavaScript的>>>.
它是什么,它做了什么？
在JavaScript中是否有一种方法可以获得字符串与正则表达式数组匹配的布尔值？
例子是('if'语句代表我想要实现的目标):
var thisExpressions = [ '/something/', '/something_else/', '/and_something_else/'];
var thisString = 'else';
if (matchInArray(thisString, thisExpressions)) {
}
我想做的事情:正如标题中所述,我想设置一个单词的CSS,如果它是一个保留字.
<html>
<body>
<code id="java">
public static void main(String[] args)<br>
{
<pre> System.out.println("Hello World!");</pre>
}
</code>
</body>
</html>
$(document).ready(function()

var code = $("#java").text();
