English 我有一些jQuery / JavaScript代码，仅当#URL中有哈希（）锚链接时才要运行。如何使用JavaScript检查此字符？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#anchorexample.com/page.html#anotheranchor基本上是这样的：
if (thereIsAHashInTheUrl) {
do this;
} else {
do this;
}
如果有人能指出我正确的方向，那将不胜感激。
sometimes you get the full query string such as "#anchorlink?firstname=mark"
this is my script to get the hash value:
var hashId = window.location.hash;
hashId = hashId.match(/#[^?&\/]*/g);
returns -> #anchorlink
var requestedHash = ((window.location.hash.substring(1).split("#",1))+"?").split("?",1);
function getHash() {
if (window.location.hash) {
var hash = window.location.hash.substring(1);
if (hash.length === 0) {
return false;
} else {
return hash;
}
} else {
return false;
}
}
window.location.hash
will return the hash identifier
输入以下内容：
<script type="text/javascript">
if (location.href.indexOf("#") != -1) {
// Your code in here accessing the string like this
// location.href.substr(location.href.indexOf("#"))
}
</script>
if(window.location.hash) {
var hash = window.location.hash.substring(1); //Puts hash in variable, and removes the # character
alert (hash);
// hash found
} else {
// No hash found
}
This is a simple way to test this for the current page URL:
