我用_IEAction($oLink, "focus"),后面加个Send("{Enter}")可以实现代码如下,问题是_IEAction($oLink, "click"),为何会出现对话框一闪而过呢?

#include <IE.au3>

$oIE = _IECreate("http://www.sciencedirect.com/science/article/pii/B9780122841514500002")

Local $sMyString = "pdf"
Local $oLinks = _IELinkGetCollection($oIE)
For $oLink In $oLinks
        Local $sLinkText = _IEPropertyGet($oLink, "innerText")
        If StringInStr($sLinkText, $sMyString) Then
                _IEAction($oLink, "focus")
               
                ExitLoop
        EndIf
Next
Send("{Enter}")
