是否可以键入数字以使用Javascript在页面之间导航？

Question

I am trying to find out whether it is possible using javascript or jQuery to navigate a Wordpress site using your numerical keypad.

For a Flash example, see here: http://elevenfilm.com/ - type in one of the 3 digit numbers to go to that page.

Can anyone help? Thanks.

Answer 1

Here is an simple example

HTML

<input type="text" />
<div class="page page120">You're on page 120</div>
<div class="page page240">You're on page 240</div>
<div class="page page360">You're on page 360</div>

JS

$('input').keyup(function() {
   $('.page').hide();
   $('.page'+$(this).val()).show(); 
});

Edit

An ajax call might look like this, depending on your dom structure. You can set a hashtag to show the page in the url there as well.

$('input').keyup(function () {
    $.ajax({
        url: "http://yourblog.com/page/"+$(this).val()
    }).done(function (data) {
        location.hash = $(this).val();
        $('.content').html(data);
    });
});

Sven's edit would work, however a simpler (AJAX free) approach would be:

$(document).keyup(function (e) {
    var charCode = (96 <= e.which && e.which <= 105) 
        ? e.which - 48 
        : e.which;
    var keyVal = String.fromCharCode(charCode);
    if (!isNaN(parseInt(keyVal)))
        window.location.href = '/?pageId=' + keyVal
});

This will simply redirect the browser to www.domain.com/?pageId=<NumberPressed> . Without more information, it is difficult to improve this answer.

EDIT: Here's a basic JSFiddle

Answer 3

This is an extension to @DerFlatulator's answer that allows you to enter a 3 digit number before navigating to the page

// keys and loc should be outside the scope of your event handler
// a list of valid keys and their values (0-9 and 0-9 on numberpad)
var keys = { "48": 0, "49": 1, "50": 2, "51": 3, "52": 4, "53": 5, "54": 6, "55": 7, "56": 8, "57": 9, "96": 0, "97": 1, "98": 2, "99": 3, "100": 4, "101": 5, "102": 6, "103": 7, "104": 8, "105": 9 };
// used to hold the page being typed
var loc = []; 

$(document).keyup(function(e) {
    if (keys[e.keyCode]) {
        if (keys.push(keys[e.keyCode]) == 3) {
            document.location.href = "/?pageId=" & loc.join("");
        }
    }
});
