I have an option in my application where users can deactivate their profiles. Only admin can activate them again.
I have a class ActivateProfile with two methods
userExist(userName)that checks if user with that userName exists and his/her profile is deactivated- and
activateAccountByUser(userName)that activate the profile of the user again
I call a JavaScript function on the click event of an input type button. This code works fine on Chrome and Mozilla, but on Internet Explorer I get this error:
SCRIPT438: Object doesn't support property or method userExist
function activateProf() {
var userName=document.getElementById("userName").value;
if (userName == "") {
alert("Полето е задолжително");
} else {
alert(userName + "1");
ActivateProfile.userExist(userName, { callback:function(exist) {
if (userName) {
ActivateProfile.activateAccountByUser(userName);
alert("User is activated");
} else {
alert("User does not exist");
}
}});
}
}
Here is the code for Activate profile class
public void activateAccountByUser(String userName) {
try {
Connection c = DBComm.getInstance().getConnection();
Statement s = c.createStatement();
ResultSet set = s.executeQuery("select * from accounts where userName = '" + userName + "' and isauthorized='2'");
if (set.next()) {
Statement st = c.createStatement();
st.executeUpdate("update accounts set isauthorized='1' where userName='" + userName + "' and isauthorized='2'");
}
s.close();
c.close();
} catch (Exception ex) {
java.util.logging.Logger.getLogger(ActivateProfile.class.getName()).log(Level.SEVERE, null, ex);
}
}
public boolean userExist(String userName) throws SQLException {
//true exist
//false does not exist
boolean existEmbg = false;
try {
Connection c = DBComm.getInstance().getConnection();
Statement s = c.createStatement();
ResultSet set = s.executeQuery("select * from accounts where userName = '" + userName + "' and isauthorized='2'");
if (set.next()) {
existEmbg = true;
} else {
existEmbg = false;
}
s.close();
c.close();
} catch (Exception ex) {
java.util.logging.Logger.getLogger(ActivateProfile.class.getName()).log(Level.SEVERE, null, ex);
}
return existEmbg;
}
