从带有 jQuery 的页面的标题和 url 中删除元素

Question

I have a Google Instant style search script written in jQuery which pulls results from a PHP script. When a user queries something, their query is displayed in the title of the page as " QUERY - My Search Script" and in the url of the page as # QUERY . However, when you delete all the text from the search box the # still stays in the url and the title says " - My Search Script". How can I make it so when all of the search box content is cleared, the script removed the title and the #?

My jQuery code is:

$(document).ready(function(){
    $("#search").keyup(function(){
        var search=$(this).val();
        var query=encodeURIComponent(search);
        var yt_url='search.php?q='+query+'&category=web';
        window.location.hash=query;
        document.title=$(this).val()+" - My Search Script";

        $.ajax({
            type:"GET",
            url:yt_url,
            dataType:"html",
            success:function(response){
                $("#result").html(response);
            }
        });
    });
});

You can tidy the <title> up easy enough but you won't be able to consistently remove the # from the URL once you've set a hash. The only browser that seems to get rid of it is Firefox.

$(document).ready(function(){
  $("#search").keyup(function(){
    var search=$(this).val();
    var query=encodeURIComponent(search);
    var yt_url='search.php?q='+query+'&category=web';
    window.location.hash=query;
    // You may want to use a better title than '\xa0' (blank)
    document.title = search=='' ? '\xa0' : search+" - My Search Script";

    $.ajax({
      type:"GET",
      url:yt_url,
      dataType:"html",
      success:function(response){
        $("#result").html(response);
      }
    });
  });
});

How about something like this:

$(document).ready(function(){
    $("#search").keyup(function(){
        var search=$(this).val();
        var query=encodeURIComponent(search);
        var yt_url='search.php?q='+query+'&category=web';

        $.ajax({
            type:"GET",
            url:yt_url,
            dataType:"html",
            success:function(response){
                $("#result").html(response);
                if (query == "") {
                    window.location.hash=query;
                    document.title=$(this).val()+" - My Search Script";
                } else {
                    window.location.hash=query;
                    document.title="My Search Script";
                }
            }
        });
    });
});

The changes I made are:

• Don't update the title and hash until the new data is loaded.
• Behave differently if the searched for query is an empty string.

Try this:

$(document).ready(function() {
    $('#search').keyup(function() {
        var search = $(this).val();
        if(search == '') {
            window.location.hash = '';
            document.title = 'My Search Script';
            $('#result').empty();
        }
        else {
            window.location.hash = encodeURIComponent(search);
            document.title = search + ' - My Search Script';

            $.ajax({
                type: 'GET',
                url: 'search.php',
                data: {q: search, category: 'web'},
                dataType: 'html',
                success: function(response){
                    $('#result').html(response);
                }
            });
        }
    });
});

I've used the data option of $.ajax so that you don't need to build the url yourself.

I don't think you can guarantee to get rid of the hash in the URL: Some browsers remove it, others don't.
