```javascript// 键盘与最后展示页
function createPageHTML(_nPageCount, _nCurrIndex, _sPageName, _sPageExt) {
var hbo1;
var dissss = document.getElementById("div2");
var pic = document.getElementById("scroll");
var pic1 = document.getElementById("cont");
if (_nPageCount == null || _nPageCount <= 1) {
return;
}
var nCurrIndex = _nCurrIndex || 0;
if (nCurrIndex === 0) {
hbo1 = _sPageName + "_" + (nCurrIndex + 1) + "." + _sPageExt;
document.getElementById("nexttt").href = hbo1;
} else if (nCurrIndex === 1) {
if (_nPageCount === 2) {
hbo1 = _sPageName + "." + _sPageExt;
document.getElementById("preee").href = hbo1;
} else {
hbo1 = _sPageName + "_" + (nCurrIndex + 1) + "." + _sPageExt;
document.getElementById("preee").href = hbo1;
}
} else {
hbo1 = _sPageName + "_" + (nCurrIndex + 1) + "." + _sPageExt;
}
document.getElementById("nexttt").onclick = function() {
pic.style.display = "none";
dissss.style.display = "block";
};
document.getElementById("preee").onclick = function() {
pic.style.display = "none";
};
}
```
根据提供的内容，我完成了以下内容重构：
```javascript
if (nCurrIndex === 0) {
document.getElementById("preee").href = _sPageName + "." + _sPageExt;
document.getElementById("nexttt").href = _sPageName + "_" + (nCurrIndex + 1) + "." + _sPageExt;
} else if (nCurrIndex === (_nPageCount - 1)) {
document.getElementById("preee").href = _sPageName + "_" + (nCurrIndex - 1) + "." + _sPageExt;
document.getElementById("nexttt").onclick = function() {
pic.style.display = "none";
dissss.style.display = "block";
pic1.style.display = "none";
};
} else {
document.getElementById("preee").href = _sPageName + "_" + (nCurrIndex - 1) + "." + _sPageExt;
document.getElementById("nexttt").href = _sPageName + "_" + (nCurrIndex + 1) + "." + _sPageExt;
}
```
请注意，我已经将代码进行了格式化，以提高可读性。
这段代码是 JavaScript 代码，用于实现分页功能。其中 `document.getElementById("nexttt").href` 和 `document.getElementById("preee").href` 分别用于获取下一页和上一页的链接地址。`_sPageName`、`_nCurrIndex` 和 `_sPageExt` 是变量，分别表示当前页面名称、当前页码和页面扩展名。`keyUp(e)` 函数用于处理键盘事件，当按下右箭头键时，跳转到下一页；当按下左箭头键时，跳转到上一页。最后，调用 `createPageHTML(2,0,"t20150416_518336401","shtml")` 函数创建第 2 页的内容。
