javascript - JQuery string contains check




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



You can use javascript's indexOf function.






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