Button click not triggering javascript function in Chrome but working fine in IE

Button click not triggering javascript function(InsertRecord()) in Chrome but working fine in IE.

<input id="submit" type="button" value="Request Access" onclick="InsertRecord()" style="width:160px;"/>


function InsertRecord()
    {
        var txtUserName = document.getElementById('txtUserName').value;
        var txtDept = document.getElementById('ddlDept').value;
        var txtClass = document.getElementById('txtClass').value;
        var txtRole = document.getElementById('ddlRole').value;
        var txtAccess = document.getElementById('ddlAccess').value;
        if (txtUserName.length != 0 || txtDept.length != 0 || txtClass.length !=0 || txtRole.length !=0 || txtAccess.length !=0)
        {
            var connection = new ActiveXObject("ADODB.Connection");
            var connectionstring = "Data Source=dvuksdcwsql001;Initial Catalog=RP_5500_AppDB;Persist Security Info=True;User ID=CPT_DEV;Password=Cpt%100@123;Provider=SQLOLEDB";
            connection.Open(connectionstring);
            var rs = new ActiveXObject("ADODB.Recordset");
            rs.Open("insert into Range_Plan_Access values('" + txtUserName + "','" + txtDept + "','" + txtClass + "','" + txtRole + "','" + txtAccess + "')", connection);
            alert("Access Requested Successfully!");            

            connection.close();
        }
        else
        {
            alert("Please enter a value for User Name \n Department \n Class \n Role \n Access Required!");
        }
    }  

Could you please let me know the issue here?

Thanks,
