How to use if to find a substring inside a string with JavaScript or jQuery, using TamperMonkey and possibly an array? -
so i'm writing tampermonkey script use on facebook (as might tell on id's & classes) , i've run wall. total writers block. i'm trying figure out how can write if statement allow me find specific strings in existing string. now, i've looked around ideas , regular expressions aren't working me, nor .test or .match working me either. i'm little confused , needing insight might able do. love use array if possible since i'm going searching many strings.
here snippet of code need help:
var checkname = setinterval(function() { if ($("span[id^='fb-timeline-cover-name']").length) { var str = document.getelementbyid("fb-timeline-cover-name").innertext; var res = str.tolowercase(); if (res.substring(0,3) == "ssg") { $("button[id^='u_0_12']").click(); } clearinterval(checkname); } }, 50);
instead of:
if(res.substring(0,3) == "ssg") {
i'd able simple like:
if(res.match(this_array)) {
but i'm sure that's wrong syntax together. anyone? help? in advance!
it seems string/match can useful.
but not sure this_array
referring here.
hope snippet useful
var str = document.getelementbyid("fb-timeline-cover-name").innertext; var res = str.match(/asdfssgasdf/g); document.write('<pre>'+res+'</pre>');
edit
another string method can handy string includes.
it retuns boolean value, true or false
