How to turn the previous article to the next article by pressing the keyboard direction keys

This function is used in many Novel sites and picture sites are often used. You can pay attention to it. Let’s talk about the specific modification methods to make DreamWeaver achieve the effect of turning pages up and down:

Implementation steps:

1 , First we open include/arc.archives.class.php and find the following code:

$this->PreNext[&#39;pre&#39;] = "上一篇：<a href=&#39;$mlink&#39;>{$preRow[&#39;title&#39;]}</a> ";

Replace it with the following code:

$this->PreNext['pre'] = "$mlink ";
$this->PreNext[&#39;next&#39;] = "下一篇：<a href=&#39;$mlink&#39;>{$nextRow[&#39;title&#39;]}</a> ";

In this way, the PHP code has been modified and can be saved.

2. Next, we use js to call on the content page. Add the following code:

<script type="text/javascript" language="javascript">
 < !--document.onkeydown = nextpage;
 var prevpage = &#39;{dede:prenext get=&#39;pre &#39;/}&#39;;
 var nextpage = &#39;{dede:prenext get=&#39;next &#39;/}&#39;;
 var index_page = "index.html";
 //var bookpage="index.html";
 function nextpage(event) {
  eventevent = event ? event: (window.event ? window.event: null);
  //if (event.keyCode==13) location=bookpage
  if (event.keyCode == 13) location = index_page
  if (event.keyCode == 37) {
   if (prevpage != &#39;&#39; && prevpage != &#39;上一篇：没有了 &#39;) location = prevpage;
   else alert(&#39;这是第一页&#39;);
  }
  if (event.keyCode == 39) {
   if (nextpage != &#39;&#39; && nextpage != &#39;下一篇：没有了 &#39;) location = nextpage;
   else alert(&#39;已经是最后一页了&#39;);
  }
 }
 //-->
 function getElement(aID) {
  return (document.getElementById) ? document.getElementById(aID) : document.all[aID];
 }
 function makeRequest(url) {
  http_request = false;
  if (window.XMLHttpRequest) { //Mozilla,Safari,...
   http_request = new XMLHttpRequest();
   if (http_request.overrideMimeType) {
    http_request.overrideMimeType(&#39;text/xml&#39;);
   }
  } else if (window.ActiveXObject) { //IE
   try {
    http_request = new ActiveXObject("Msxml2.XMLHTTP");
   } catch(e) {
    try {
     http_request = new ActiveXObject("Microsoft.XMLHTTP");
    } catch(e) {}
   }
  }
  if (!http_request) {
   alert(&#39;Giving up:(Cannot create an XMLHTTP instance)&#39;);
   return false;
  }
  return http_request;
 }
</script>

to the position before 6c04bd5ca3fcae76e30b72ad730ca86d. This completes all modifications.

3. Finally, we can update the document.
