如何解决Cognos 11 - 搜索和选择提示 - 重置选择、输入关键字和结果
我需要在单击按钮时重置提示，在我的情况下是“RESET”按钮，如下面的屏幕截图所示。我可以在 customControl 中使用 clearValues() JavaScript API 清除 Month-Year 和 Order-Method VALUE 提示，但使用 Search and Select 提示 clearValues() 函数仅清除 SnS 提示中结果窗格中的选定值，但我们需要清除结果窗格中的输入关键字和结果，我可以通过设置输入标签的 .value（用于关键字）并重置包含结果选项的 Div 的 html 来清除它们，但是当页面重新加载之前选择的关键字，结果选择重新出现，例如在您重置然后将年份从 2011 年切换到 2012 年或反之亦然后，之前搜索的输入关键字和结果会重新出现在 SnS 提示中。
