What kind of validation you want to do on textbox to search record?

Try this. Use the OR Operator.

var reg1 = new RegExp('^[a-zA-Z]+$');
var reg2 = new RegExp('^[a-zA-Z0-9]+$');

if (!reg1.test(Name) || !reg1.test(regno))
{
alert('"Invalid Input Value");
return false;
}

Dear Sanjay,

Replace your code as below:

JavaScript

function validateField() {
    var name = document.getElementById("txt_name").value;
    var regNo = document.getElementById("txt_reg_no").value;
    if ((name == null || name == "") && (regNo == null || regNo == "")) {
        alert("Your Message");
        return false;
    }
}
