Jquery 你能在不影响历史的情况下使用哈希导航吗

恐怕它可能是impossible，但是有没有办法更改URL without leaving an entry in the browser's history和without reloading的散列值呢？还是做同样的事？

As far as specifics go, I was developing some basic hash navigation along the lines of:

//hash nav -- works with js-tabs
var getHash = window.location.hash;
var hashPref = "tab-";
function useHash(newHash) {
    //set js-tab according to hash
    newHash = newHash.replace('#'+hashPref, '');
    $("#tabs li a[href='"+ newHash +"']").click();
}
function setHash(newHash) {
    //set hash according to js-tab
    window.location.hash = hashPref + newHash;

    //THIS IS WHERE I would like to REPLACE the location.hash
    //without a history entry

}
    // ... a lot of irrelavent tabs js and then....

    //make tabs work
    $("#tabs.js-tabs a").live("click", function() {
        var showMe = $(this).attr("href");
        $(showMe).show();
        setHash(showMe);
        return false;
    });
    //hash nav on ready .. if hash exists, execute
    if ( getHash ){
        useHash(getHash);
    }

Using jQuery, obviously. The idea is that in this specific instance 1) making the user go back over every tab change could effectively 'break the back button' by piling up needless references, and 2) not retaining which tab they're currently on if they hit refresh is an annoyance.
