+</span> * @class Ext.form.field.Hidden
+ * @extends Ext.form.field.Base
+ * <p>A basic hidden field for storing hidden values in forms that need to be passed in the form submit.</p>
+ * <p>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.</p>
+ * <p>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}.</p>
+ * <p>Example:</p>
+ * <pre><code>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'
+ }],
- // private
- onRender : function(){
- Ext.form.Hidden.superclass.onRender.apply(this, arguments);
- },
+ buttons: [{
+ text: 'Submit',
+ handler: function() {
+ this.up('form').getForm().submit({
+ params: {
+ hidden_field_2: 'value from submit call'
+ }
+ });
+ }
+ }]
+});</code></pre>
+ * <p>Submitting the above form will result in three values sent to the server:
+ * <code>text_field=value+from+text+field&hidden_field_1=value+from+hidden+field&<br>hidden_field_2=value+from+submit+call</code></p>
+ *
