我目前正在尝试模仿enyo.Popup的行为。我在github上看过,但很难理解它。
尤其是这是我遇到麻烦的代码:
handlers: {
//...
onRequestShow: "requestShow",
onRequestHide: "requestHide"
},
//* @public
events: {
//* Fires after the popup is shown.
onShow: "",
//* Fires after the popup is hidden.
on
在教程中使用以下方法提取数据库数据:
install.packages('RODBC')
require(RODBC)
myNewDB=odbcConnect("QV Training")
我得到了一个错误:
In odbcDriverConnect("DSN=QV Training")
Data source name not found and no default driver specified
In odbcDriverConnect("DSN=QV Training") : ODBC connection faile
