Is there a function in jQuery or JavaScript that does the same as strstr() in PHP?
I have an AJAX response that should be 1,2,3,12,13,23 or 123. I want to check if 1 exists, then if 2 exists then if 3 exists.

The strstr() function searches for the first occurrence of a string inside another string. Note: This function is binary-safe. Note: This function is case-sensitive. For a case-insensitive search, use stristr() function.
Substr in PHP This function is present in almost in all language and have the similar syntax and meaning. String – This is the input string which we need to split and a mandatory field. Start – This is the starting Position from which we need to return the substring it can be positive, negative and zero.
The C library function char *strstr(const char *haystack, const char *needle) function finds the first occurrence of the substring needle in the string haystack. The terminating '\0' characters are not compared.
Note: This function is case-sensitive. For case-insensitive searches, use stristr().
Try using this:
function strstr(haystack, needle, bool) {
// Finds first occurrence of a string within another

var pos = 0;
haystack += "";
pos = haystack.indexOf(needle); if (pos == -1) {
return false;
} else {
if (bool) {
return haystack.substr(0, pos);
} else {
return haystack.slice(pos);
}
}
}

Overall phpjs is pretty phenomenal.
