javascript - Check if a string has a certain piece of text





Possible Duplicates:
Check if text is in a string
JavaScript: string contains






I'm trying to check if a string I import into my application has a certain piece of text. I know how to do this with jQuery, but how do I do it with straight up JavaScript?


Answer



Here you go: ES5




var test = 'Hello World';
if( test.indexOf('World') >= 0){
// Found world
}


With ES6 best way would be to use includes function to test if the string contains the looking work.



const test = 'Hello World';

if (test.includes('World')) {
// Found world
}
