trafficinc / stristr.js
Created November 7, 2019 20:30
JavaScript, finds first occurrence of a string within another, case insensitive. Inspiration from the similar PHP function.
function stristr (haystack, needle, bool) {
var pos = 0;
haystack += '';
pos = haystack.toLowerCase().indexOf((needle + '').toLowerCase());
if (pos == -1) {
return false;
} else {
if (bool) {
return haystack.substr(0, pos);
