I am trying to override onRender event in ExtJS 3.4.0 but this gives a script error: object does not support callParent. My objective is to enable or disable buttons based on the rights from session object.
Ext.override(Ext.Button, {
onRender: function () {
this.callParent();
console.log('do something');
}
});
I have resolved with these lines of code:
Ext.onReady(function () {
Ext.QuickTips.init();
// get rights here
if (roles.length > 0) {
Ext.override(Ext.Button, {
initComponent: function () {
//filter rights here with matching text
// if length is greater than 0, then enable disable buttons
if (buttonRights.length > 0) {
if (this.text == buttonRoles[0].ItemText) {
this.setDisabled(!roles[0].IsAllowed);
}
}
}
});
}
});
