Allow alphanumeric with spanish regex in javascript?

Question

Hi I tried the following code in javascript,

if(/[^0-9a-zñáéíóúü]/i.test(string))
{
    alert("oK WITH THE INPUT");
}
else
{
    alert("error");
}

But I am getting a result OK , even I entered the @ characters in my string. I dont why.

My aim is to allow alphanumeric(English and spanish).

Please help me in this.

Thanks in advance.

if(/^[0-9a-zñáéíóúü]+$/i.test(string))
{
    alert("oK WITH THE INPUT");
}
else
{
    alert("error");
}

• Make the regex match more than one character with the + quantifier
• Make it match the entire input with ^ and $ anchors
• Don't negate the character class (remove the ^ )
