Find a way to don't match urls containing @ in regex

I have a regex for validation of urls. But I don't want to match urls containing the character "@". How can 开发者_运维知识库I solve that?

regexp = /((ftp|http|https):\/\/)?(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/; 

Well, you can always first check if your url contains @ using indexOf(), a string method. If it returns a number other than -1, your url contains @. If it doesn't, proceed using your regex.

Edit: you can use this code:

if( myString.indexOf('@') == -1 && myString.match(regexp)) { 
    return true; 
} 
else { 
    return false; 
}

Which can be further shortened to:

return myString.indexOf('@') == -1 && myString.match(myString);

Thanks goes to @idealmachine for providing this code faster than me.

That should do:

regexp = /((ftp|http|https):\/\/)?[^\/:\s]+(:[0-9]+)?(\/[^@]*)?/;
