How to replace element's attr href with each ? // strip url

问题

im trying to change href with each method,

here is demo, inspect a, you'll see there is no change

html:

<a href="#/news">News</a>
<a href="#/news/detail">Detail</a>
<a href="#/sport">Sport</a>
<a href="#/sport/football">Football</a>​​​​​​​​​​​​

jQuery:

$('a').each(function() {
  $(this).attr('href').replace('#/',''); //tried to erase #/ from all hrefs
});​

回答1:

The code you posted will get the value as a string then properly replace the values but it immediately discards the result. You need to pass in the replaced value to attr. Try the following

$('a').each(function() {
  var value = $(this).attr('href');
  $(this).attr('href', value.replace('#/',''));
});​

回答2:

var href = $(this).attr('href');
$(this).attr('href', href.replace('#/',''));

回答3:

You can also check href value and make condition

<script type="text/javascript">
$('a').each(function() {
    var value = $(this).attr('href');
    if(value=='http://google.com')
    {
        $(this).attr('href', 'http://youtube.com');
    }
});​
</script>
