}How do I check if a string contains another string in Swift
let string = "hello Swift"
if string.contains("Swift") {
print("exists")
}if str contains jquery
if (str.indexOf("Yes") >= 0)
//case insensitive version
if (str.toLowerCase().indexOf("yes") >= 0)string check javascript
if (typeof myVar === 'string') { /* code */ };check for substring javascript
const string = "javascript";
const substring = "script";
console.log(string.includes(substring)); //truejavascript string contains
var string = "foo",
substring = "oo";
console.log(string.includes(substring));check if string contains substring
Like this:
if (str.indexOf("Yes") >= 0)
...or you can use the tilde operator:
if (~str.indexOf("Yes"))
This works because indexOf() returns -1 if the string wasn't found at all.
Note that this is case-sensitive.
If you want a case-insensitive search, you can write
if (str.toLowerCase().indexOf("yes") >= 0)
Or:
if (/yes/i.test(str))Copyright © 2021 Codeinu
