Question

the script i’ve pieced together so far looks like this:

<script type="text/javascript">
/* KEYNAV */
document.onkeydown = function(e) {
if (! e) var e = window.event;
var code = e.charCode ? e.charCode : e.keyCode;
if (! e.shiftKey && ! e.ctrlKey && ! e.altKey && ! e.metaKey) {
if (code == Event.KEY_LEFT) {
if ($('previous_page_link')) location.href = $('previous_page_link').href;
} else if (code == Event.KEY_RIGHT) {
if ($('next_page_link')) location.href = $('next_page_link').href;}
}
}); 
</script>

and my html looks like this:

<p>
{block:PreviousPage}
<a id="previous_page_link" href="{PreviousPage}">PREVIOUS PAGE</a> 
{/block:PreviousPage}

{block:NextPage}
<a id="next_page_link" href="{NextPage}">NEXT PAGE</a>
{/block:NextPage}
</p>

the {PreviousPage} / {NextPage} code represents dynamic page links which are different depending on which page you are on. this particular question is specific to tumblr, but generally as well:

is there a way to get my left and right arrow keys to trigger these dynamic links?

thank you for reading and any help with this is greatly appreciated.

Answer 1

function leftArrowPressed() {
   // Your stuff here
}

function rightArrowPressed() {
   // Your stuff here
}

document.onkeydown = function(evt) {
    evt = evt || window.event;
    switch (evt.keyCode) {
        case 37:
            leftArrowPressed();
            break;
        case 39:
            rightArrowPressed();
            break;
    }
};
