Which function do I use to find out if str1 contains str2?

Javascript Solutions

Solution 1 - Javascript

You can use javascript's indexOf function.

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

Solution 2 - Javascript

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

sttr1.search(str2);

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

Solution 3 - Javascript

Please try:

str1.contains(str2)

Solution 4 - Javascript

I use,

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

Solution 5 - Javascript

If you are worrying about Case sensitive change the case and compare the string.

 if (stringvalue.toLocaleLowerCase().indexOf("mytexttocompare")!=-1)
        {
            
            alert("found");
        }
