Basically, I'm doing this:
var phone = $("#phone").val();
Then I want to check if:
1) Phone contains only numbers
2) Phone contains at least 10 digits
But the problem is, from my experience, using $("something").val()
returns it as a string so isNaN() fails. But I don't want use parseInt() either since it will change strings into numbers as well and then isNaN() will always pass.
Thoughts?
You could use a regular expression like this one:
if (phone.match(/^\d{10,}$/)) {
// the input contains at least 10 digits
}
Like @Andrew said you can use reg ex to do the check like this.
var regExp = new RegExp("^"+pattern+"$","");
return regExp.test(value);
Place the above in a function and pass the patern into it to make it re-useable.
Replace pattern with the one that matches your requirements. The one from @Andrew looks like it'll work.
