Remove ads on the web (Baidu, Google, etc.)

The original page, a lot of ads

Processed after the page, no ads, a lot of good mood

Press F12 to paste the following code at the cursor:

Alert (document.getElementsByTagName ("iframe"). length);//Total number of IFRAME for
(var i=20;i>=0;i--) {// You can also use the total number of IFrame obtained above
	var do1=document.getelementsbytagname ("iframe") [i];
	if (Do1 = = null) {
	}else{
		do1.parentNode.removeChild (do1);
		/* document.getElementsByTagName ("iframe") [i].src= ';
		document.getElementsByTagName ("iframe") [i].style.height= "1px";
		document.getElementsByTagName ("iframe") [i].height= "1px";
		*/
	}
}

Press ENTER to see the page, the ad is not

Update code:

Delete iframe ad content
var iframecount=document.getelementsbytagname ("iframe"). Length;
for (Var i=iframecount;i>=0;i--) {
	var do1=document.getelementsbytagname ("iframe") [i];
	if (Do1 = = null) {
	}else{
		//do1.style.display= "None";
		Do1.parentNode.removeChild (DO1);
	}
}
Remove the embedded ad placeholder, and some use the above to remove the IFRAME and occupy a bit, you need to execute the next
var inscount=document.getelementsbytagname ("ins"). Length;
for (Var i=inscount;i>=0;i--) {
	var do1=document.getelementsbytagname ("ins") [i];
	if (Do1 = = null) {
	}else{
		//do1.style.display= "None";
		Do1.parentNode.removeChild (DO1);
	}
}
