从＃id = 3333获取参数值

Question

I have this,

var stateObj = { foo: "foo" };
function change_my_url()
{
    if (window.history && window.history.pushState){
        history.pushState(stateObj, "page 2", "foo.html?id=3333");
    }else{
        location.hash = '#id=3333'
    }
}

In case window.history isnt supported, it will be #id=3333. Now if you load the page and it has a location.hash, it $.post request to file.php with it:

$.post('do_something.php', { hash: hash }, function(result) { $('#photos').html(result); });

in do_something im grabbing it with $_POST['hash'];. Now $_POST['hash'] will contain #id=3333. How can i divide in params and grab the value, '3333' ?

Answer 1

There are many ways to turn the string #id=3333 into the string 3333 .

Split on '=':

$parts = explode('#', $inputString);
$value = $parts[1];

Remove the first four chars:

$value = substr($inputString, 3);
