close extjs window after form submission - extjs

Question

I have an extjs2 formpanel:
var fsf = new Ext.FormPanel({
labelWidth: 75, // label settings here cascade unless overridden
frame:true,
id: 'formPanel',
title: 'Simple Form with FieldSets',
bodyStyle:'padding:5px 5px 0',
width: 550,
items: [{
xtype:'fieldset',
checkboxToggle:true,
title: 'User Information',
autoHeight:true,
defaults: {width: 210},
defaultType: 'textfield',
collapsed: true,
items :[{
fieldLabel: 'First Name',
name: 'first',
allowBlank:false
},{
fieldLabel: 'Last Name',
name: 'last'
},{
fieldLabel: 'Company',
name: 'company'
}, {
fieldLabel: 'Email',
name: 'email',
vtype:'email'
}
]
},{
xtype:'fieldset',
title: 'Phone Number',
collapsible: true,
autoHeight:true,
defaults: {width: 210},
defaultType: 'textfield',
items :[{
fieldLabel: 'Home',
name: 'home',
value: '[phone]'
},{
fieldLabel: 'Business',
name: 'business'
},{
fieldLabel: 'Mobile',
name: 'mobile'
},{
fieldLabel: 'Fax',
name: 'fax'
}
]
}],
buttons: [{
text: 'Save',
handler: function(){
var form = Ext.getCmp('formPanel').getForm();
if(form.isValid())
form.submit({
waitMsg:'Loading...',
url: 'RepeatSession.jsp',
success: function(form,action) {
//we have to close the window here!!
},
failure: function(form,action){
Ext.MessageBox.alert('Erro',action.result.data.msg);
}
});
}
},{
text: 'Cancel'
}]
});
and a window:
win = new Ext.Window(
{
layout: 'fit',
width: 500,
height: 300,
modal: true,
closeAction: 'hide',
items: fsf
});
win.show();
As you can see, the form panel is inside the window as an item. I have to close the window after a successful form submission but I have no idea how to access the window object inside my success handler.
How can i hide the window after successful form submission?

Answer 1

Just save a reference to the window or one of its children before creating the form. For example you can use the button paremeter that the handler function gets passed:
handler: function(button, e){
[...]
success: function(form,action) {
button.up('.window').close();
},
Or, as you apparently already have the window in a variable (win), you can just use that to close the window:
win.close();
but that depends on the variable win being available inside the success function, which we cannot assume from the code you gave.
