Extjs 下拉树 单击+会隐藏下拉树问题

 

问题：单击+会隐藏下拉树问题

解决：重载ComboBox

Ext.override(Ext.form.ComboBox, {
onViewClick : function(doFocus) {
var index = this.view.getSelectedIndexes()[0], s = this.store, r = s.getAt(index);
if (r) {
this.onSelect(r, index);
} else if (s.getCount() === 0) {
this.collapse();
}
if (doFocus !== false) {
this.el.focus();
}
}
});
