js detects keywords in the title and description and replaces or jumps to other pages when found

Keywords General

The title cannot contain words like crack, key, serial number, or keygen. Otherwise, it should be redirected or replaced with other words.

var mflag=false;
var mtit=document.title;
var mcont=document.getElementsByName('description')[0].content;

var arr=['crack','key','serial number','registration machine'];

for(x in arr){
if (encodeURI(tit).indexOf(arr[x]) != -1){
			flag=true;
		}
	if (encodeURI(cont).indexOf(arr[x]) != -1){
			flag=true;
		}
	}
	if(flag){
		/*$('body').html('Sorry, this page has been deleted!').css({
					"font-size": "20px",
					"padding-top": "20px"
				});
		$('html').hide();		
		$('html').text('Sorry, this page has been deleted!');*/
		window.location.href = "https://yourdomain/404.htm";
	}

Keyword Encryption

var mflag=false;
var mtit=document.title;
var mcont=document.getElementsByName('description')[0].content;

var arr=['%E7%A0%B4%E8%A7%A3','key','%E5%BA%8F%E5%88%97%E5%8F%B7','%E7%89%B9%E5%88%AB%E7%89%88'];

for(x in arr){
if (encodeURI(tit).indexOf(arr[x]) != -1){
			flag=true;
		}
	if (encodeURI(cont).indexOf(arr[x]) != -1){
			flag=true;
		}
	}
	if(flag){
		/*$('body').html('Sorry, this page has been deleted!').css({
					"font-size": "20px",
					"padding-top": "20px"
				});
		$('html').hide();		
		$('html').text('Sorry, this page has been deleted!');*/
		window.location.href = "https://yourdomain/404.htm";
	}

That is to say, it increases the difficulty of reading, but the idea is good but it is not easy for others to find it.

Mainly using indexOf and JavaScript encodeURI() function

JavaScript encodeURI() Function

Definition and Usage

The encodeURI() function encodes a string as a URI.

grammar

encodeURI(URI string)

Return Value

A copy of URIstring with some characters replaced by hexadecimal escape sequences.

illustrate

This method does not encode ASCII letters and numbers, nor does it encode these ASCII punctuation characters: - _ . ! ~ * ' ( ) .

The purpose of this method is to fully encode the URI, so encodeURI() function will not escape the following ASCII punctuation characters that have special meanings in URIs: ;/?:@&=+$,#

Tips and Notes

Tip: If the URI components contain separators, such as ? and #, you should encode each component separately using the encodeURIComponent() method.

Examples

In this example, we will use encodeURI() to encode the URI:

Output

%E8%84%9A%E6%9C%AC%E4%B9%8B%E5%AE%B6
