Js array combined with strings for search (blocking advertisement judgment url, etc.) _ javascript skills

This article mainly introduces how to use arrays in js to search by using strings (shielding advertisements to determine URLs, etc.). For more information, see 1. Ad shielding

Sometimes our ad pages are controlled by js in a unified manner, and some pages do not want to display part of the ads, so we only need the id of the Article. Pure string search is simple and effective, and the script house is also in use.

Var ad_softlist = ', 133015,155868, 146429,'; if ("undefined "! = Typeof softid) {// judge whether the article id exists. if it does not exist, it is not executed. Generally, var softid = 45465 is defined on the page. if (softid! = Null & ad_softlist.indexOf (',' + softid + ',') =-1) {// display advertisement, softid is the article id}

Function checkurl (urls) {if (urls! = "") {If (urls. indexOf ('HTTP: // http ')! =-1) | urlcheck (urls )! = True) {alert ("there is a problem with the URL. You can check the newly added URL") ;}} function urlcheck (str) {var urlall = "http: //, https: //, ed2k: //, thunder: //, flashget: //, ftp: // "; var urlarr = urlall. split (","); for (var I = 0; I
 
  
-1) {return true;} return false ;}
