A basic hidden field for storing hidden values in forms that need to be passed in the form submit.
+ *This creates an actual input element with type="submit" in the DOM. While its label is + * {@link #hideLabel not rendered} by default, it is still a real component and may be sized according to + * its owner container's layout.
+ *Because of this, in most cases it is more convenient and less problematic to simply + * {@link Ext.form.action.Action#params pass hidden parameters} directly when + * {@link Ext.form.Basic#submit submitting the form}.
+ *Example:
+ *new Ext.form.Panel({
+ title: 'My Form',
+ items: [{
+ xtype: 'textfield',
+ fieldLabel: 'Text Field',
+ name: 'text_field',
+ value: 'value from text field'
+ }, {
+ xtype: 'hiddenfield',
+ name: 'hidden_field_1',
+ value: 'value from hidden field'
+ }],
+
+ buttons: [{
+ text: 'Submit',
+ handler: function() {
+ this.up('form').getForm().submit({
+ params: {
+ hidden_field_2: 'value from submit call'
+ }
+ });
+ }
+ }]
+});
+ * Submitting the above form will result in three values sent to the server:
+ * text_field=value+from+text+field&hidden_field_1=value+from+hidden+field&
hidden_field_2=value+from+submit+call
