JQuery string contains check [duplicate]

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
    console.log(str2 + " found");
}

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";

sttr1.search(str2);

it will return the position of the match, or -1 if it isn't found.

Please try:

str1.contains(str2)

I use,

var text = "some/String"; text.includes("/") <-- returns bool; true if "/" exists in string, false otherwise.
