ExtJS 4 Combobox event for selecting selected value
提问by Dawid Mazur
For some reason I need to know when user has selected value from combobox even if it is already selected. "Select" event works only if user selects unselected item. I don't see any event like "itemclick" in the docs for combobox or picker. Any ideas?
出于某种原因，我需要知道用户何时从组合框中选择了值，即使它已经被选中。“选择”事件仅在用户选择未选择的项目时才起作用。我在组合框或选择器的文档中没有看到任何类似“itemclick”的事件。有任何想法吗？

ComboBoxuses BoundListfor representing dropdown list. BoundListfires itemclickevent. You can use ComboBox's listConfigconfig in order to setup BoundListlisteners:
ComboBox使用BoundList表示下拉列表。BoundList触发itemclick事件。您可以使用ComboBox的listConfig配置来设置BoundList侦听器：
Ext.create('Ext.form.ComboBox', {
// ...
listConfig: {
listeners: {
itemclick: function(list, record) {
alert(record.get('name') + ' clicked');
}
}
}
}
Check out the demo.
