Example

To execute this example, the page must contain the DictionaryBox component named dictionaryBox (see Example of creating the DictionaryBox component ). Show the imported attribute with the ID UNITS_SYSTEM_DESCRIPTION in the MDM dictionary, and define key of the attribute, to which it is linked:

// Get MDM dictionary
var source = dictionaryBox.getSource()[0];
// Get borrowed attribute
var lookUpAttribute = source.getAttribute(null, "UNITS_SYSTEM_DESCRIPTION");
// Show the attribute
var attrs = source.getAttributes();
for (var i in attrs) {
    if (attrs[i].getKey() == lookUpAttribute.getKey()) {
        attrs[i].setVisible(true);
    };
};
console.log("Key of the lookup attribute for borrowed attribute: %s", lookUpAttribute.getLookUpKey());
// Refresh the tree of dictionary elements
dictionaryBox.getDataArea().getActiveDictTree().refreshAll();

After executing the example the dictionary shows borrowed attribute with the UNITS_SYSTEM_DESCRIPTION identifier:

The browser console shows key of the lookup attribute for borrowed attribute:

Key of the lookup attribute for borrowed attribute: 2174
