我有一些jQuery/JavaScript代码,我想只在URL中有一个散列(#)锚链接时运行。如何使用JavaScript检查这个字符?我需要一个简单的全方位测试,可以检测到如下url:

example.com/page.html #锚 example.com/page.html # anotheranchor

基本上是这样的:

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

当前回答

$('#myanchor').click(function(){
    window.location.hash = "myanchor"; //set hash
    return false; //disables browser anchor jump behavior
});
$(window).bind('hashchange', function () { //detect hash change
    var hash = window.location.hash.slice(1); //hash to string (= "myanchor")
    //do sth here, hell yeah!
});

这将解决问题;)

有时您会得到完整的查询字符串,例如“#anchorlink?”firstname =马克”

这是我获取哈希值的脚本:

var hashId = window.location.hash;
hashId = hashId.match(/#[^?&\/]*/g);

returns -> #anchorlink

下面是定期检查哈希值变化的方法,然后调用一个函数来处理哈希值。

var hash = false; 
checkHash();

function checkHash(){ 
    if(window.location.hash != hash) { 
        hash = window.location.hash; 
        processHash(hash); 
    } t=setTimeout("checkHash()",400); 
}

function processHash(hash){
    alert(hash);
}
$('#myanchor').click(function(){
    window.location.hash = "myanchor"; //set hash
    return false; //disables browser anchor jump behavior
});
$(window).bind('hashchange', function () { //detect hash change
    var hash = window.location.hash.slice(1); //hash to string (= "myanchor")
    //do sth here, hell yeah!
});

这将解决问题;)

写上以下内容:

<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>
var requestedHash = ((window.location.hash.substring(1).split("#",1))+"?").split("?",1);
