A strange js code to decrypt-CodePudding

Need to decrypt, a piece of code is as follows:
<script type="text/javascript">
$(function () {
FillHtmlContent ();
});

The function fillHtmlContent () {
SetTimeout (function () {
The eval (function (p, a, c, k, e, d) {e=function (c) {return (c
;
$(" book_content "). The addClass (" book - content - show ");
}, 0);
}
</script>

Find a decoding online website, https://www.sojson.com/jsjiemi.html, the decoding result:
$(function () {
FillHtmlContent ();
});

The function fillHtmlContent () {
SetTimeout (function () {
The eval (' $(". Book_content "). The HTML (" & lt; Input id=\ "doctype " type=\ "hidden " value=https://bbs.csdn.net/"img " & gt;

" ); ')

;
$(" book_content "). The addClass (" book - content - show ");
}, 0);
} & lt;/script>

Get the desired results, wanted to call decoding https://www.sojson.com/jsjiemi.html online interface, but this website is encrypted, even can't use F12, don't know how to do?
