How to validate Spaces, between alphanumeric inputs

I am validating my text box input using regEx. I have my condition like,"it may take either only characters or both alphanumeric inputs" but it should not take only numbers.

I am using this code for validation:

var regex=/^[0-9]*?[a-zA-Z]+|[a-za-Z]+?[0-9]*$/;

if(!regex.test(city)){
    $("#error").html("Please enter a city details Correctly");
}

Its works fine for my condition but the issue is, this even takes spaces between alphanumeric/characters'. How to avoid spaces for my above condition.Please help me to get out from this.

Thanks in advance.

Try this,

var regex=/^(?:(?:[0-9]*?[a-zA-Z]+)|(?:[a-zA-Z]+?[0-9]*))$/;
var city = "bangalore east";
if(!regex.test(city)){
    alert("Please type valid city");
} else {
    alert(city);
}

try out this :

var regex = /^([\d]*?[a-zA-Z]+[a-zA-Z\d]*|[a-zA-Z]+?[a-zA-Z\d]*)$/;

You can use:

var regex=/^(\d*[a-zA-Z]+|[a-zA-Z]+\d*)$/;

Just put your regex into capturing or non-capturing group, so that it would do an exact line match or otherwise, it would do a partial match like your's.

^([0-9]*?[a-zA-Z]+|[a-zA-Z]+?[0-9]*)$

^(?:(?:[0-9]*?[a-zA-Z]+)|(?:[a-zA-Z]+?[0-9]*))$

Try this.See demo.
