SCRIPT438: Object doesn't support property or

Question

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;
}

Answer 1

I forgot to use var on my item variable

Incorrect code:

var itemCreateInfo = new SP.ListItemCreationInformation();
item = list.addItem(itemCreateInfo); 
item.set_item('Title', 'Haytham - Oil Eng'); 

Correct code:

var itemCreateInfo = new SP.ListItemCreationInformation();
var item = list.addItem(itemCreateInfo);  
item.set_item('Title', 'Haytham - Oil Eng');

Answer 2

I have added var for all the variables in the corrosponding javascript. That solved the problem in IE.

Previous Code

billableStatus = 1 ;
var classStr = $(this).attr("id").split("_");  
date = currentWeekDates[classStr[2]]; // Required    

activityNameId = "initialRows_" + classStr[1] + "_projectActivityName";
activityId = $("#"+activityNameId).val();        

var projectNameId = "initialRows_" + classStr[1] + "_projectName" ;
projectName = $("#"+projectNameId).val();        

var timeshitEntryId = "initialRows_"+classStr[1]+"_"+classStr[2];     
timeshitEntry = $("#"+timeshitEntryId).val();   

New Code

var billableStatus = 1 ;
var classStr = $(this).attr("id").split("_");  
var date = currentWeekDates[classStr[2]]; // Required    

var activityNameId = "initialRows_" + classStr[1] + "_projectActivityName";
var activityId = $("#"+activityNameId).val();        

var projectNameId = "initialRows_" + classStr[1] + "_projectName" ;
var projectName = $("#"+projectNameId).val();        

var timeshitEntryId = "initialRows_"+classStr[1]+"_"+classStr[2];     
var timeshitEntry = $("#"+timeshitEntryId).val();   

Answer 3

After some days searching the Internet I found that this error usually occurs when an html element id has the same id as some variable in the javascript function. After changing the name of one of them my code was working fine.

Answer 4

In my case I had code like this:

function.call(context, arg);

I got error message under IE

TypeError: Object doesn't support property or method 'error'

In the body of 'function' I had "console.error" and it turns that console object is undefined when your console is closed. I have fixed this by checking if console and console.error are defined
