javascript - 如何使用JavaScript检查URL中的＃哈希？(How can you check for a #hash in a URL using JavaScript?)

Question

I have some jQuery/JavaScript code that I want to run only when there is a hash ( # ) anchor link in a URL.(我有一些jQuery / JavaScript代码，仅在URL中有哈希（ # ）锚链接时才要运行。)

How can you check for this character using JavaScript?(如何使用JavaScript检查此字符？) I need a simple catch-all test that would detect URLs like these:(我需要一个简单的包罗万象的测试，该测试可以检测如下URL：)

• example.com/page.html#anchor
• example.com/page.html#anotheranchor

Basically something along the lines of:(基本上是这样的：)

if (thereIsAHashInTheUrl) {        
    do this;
} else {
    do this;
}

If anyone could point me in the right direction, that would be much appreciated.(如果有人能指出我正确的方向，那将不胜感激。)
