Hi Anoop,\
\
You can search sub [string](https://www.mindstick.com/articles/1527/string-split-in-c-sharp) in a string using search() method of Javascript\
\
Here is the example,\

```
var mainString = 'Hello world'; if (mainString.search('world') >= 0)        alert('Exist');
```

Hop this will solve your problem.
