JQuery string contains check

Question

I need to check whether a string contains another string or not?

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

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

Answer 1

Check out JavaScript's indexOf function. http://www.w3schools.com/jsref/jsref_IndexOf.asp

Answer 2

Below code you can check "hello" string is exit or not in given string.

if (our_string.indexOf('hello') > -1)
{
  alert("hello found inside our_string");
}

I hope this answer is useful for you.

Answer 3

I use,

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

Answer 4

This is working for me

if (~str.indexOf("Yes"))

Answer 5

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

 if (stringvalue.toLocaleLowerCase().indexOf("mytexttocompare")!=-1)
        {

            alert("found");
        }

Answer 6

Please try:

str1.contains(str2)
