Save the Address bar file name a small tool with sequential pictures or web pages

How to use:

Paste the code into the console, then enter, and a button will appear in the upper-left corner to switch to the next page by clicking the button. Although the method may be low, but I really do not want to change the address bar that number, too bad choice.

function last () {    var href=window.location.href;    var line=href.lastindexof ('/');    var dot=href.lastindexof ('. ');    var con=href.slice (0,line+1);    var last=href.slice (dot);    var num=href.slice (Line+1,dot)/1+1;    Console.log (con+num+last);    Window.location.href=con+num+last;} function Appchild () {    var btn = document.createelement ("input");//js new element    Btn.onclick = last;//Add a click event to an element    btn.setattribute ("type", "button");//element plus attribute    btn.setattribute ("value", "next");//Add attribute    to Element btn.style.position = "fixed";//js set style    btn.style.top = "20px";//js set style    Btn.style.left = "20px";//js set style    btn.style.width= "100px";//js set style    btn.style.height = "30px";//js set style    btn.style.fontSize = "20px";// JS Set style    Btn.style.color = "Red";//js set style    btn.style.fontWeight = "bold";//js set style    Document.body.appendChild (BTN);//Put the element into the body tag inside the}appchild ();
