其他人刚刚发布了同样的问题! :)
您应该使用commandButton 的
oncomplete
属性而不是onclick
。 Click javascript 事件发生在页面回发之前,可能会导致您的对话框由于页面重新加载而不会出现。oncomplete="dlg3.show()"
将在回发后显示对话框。Somebody else just posted the same problem! :)
You should use the
oncomplete
attribute instead ofonclick
of the commandButton. The click javascript event occurs before the page posts back, likely causing your dialog not to appear because of the page reloading.oncomplete="dlg3.show()"
will display the dialog AFTER the postback.
