# Restrict special characters using Javascript

I have a small requirement where I want to validate some text with special characters whether the text contain any special character or not.

If its contain any of the special character except alphanumeric then I need to define the proper action accordingly.

And here is the code snippet for you,

var regExpression = /[`~!@#\$%^&*()_|+-=?;:'",.<>{}[]/]/gi; // don't use any additional double quote here
var isContainSplChar = regExpression.test(searchedText);
if (isContainSplChar ) {

//my action should define here
return false;
}
