AutoHotKey JavaScript Link

问题

I'm not familiar with JavaScript and web development, as my experience is in Java and C++ primarily, and I'm even new to that. I'm using AutoHotKey to automate data entry for the company I work for, and in order to get into the form that to fill out a new item, I have to click a link. I've had no problem when the links all had URLs for href values, but now I'm running into one that is a JavaScript link, and I don't know how to click it... here is the code for the link.

<a href="javascript:" 
tabindex="7"
onclick="this.parentNode.parentNode._skip=true;$find('ctl00_MainContent_view1Extender').executeAction('ActionBar',0,null,0);return false;"
onfocus="$showHover(this,&quot;ctl00_MainContent_view1Extender$0$ActionGroup$0&quot;,&quot;ActionGroup&quot;,2)" 
title="New Reimbursement" 
onblur="$hideHover(this)">New Reimbursement</a>

And I'm not sure what to do with it, despite a days worth of Googling.

Thanks in advance!

More then one way get to an element without a ID or Name, but one of the easy ones are to loop over the elements on the page until you get to the one you need.

Example Function:

LoopElements(Elements, String, attribute="title")
{
try
Loop % Elements.Length ; check each element
    If instr((Elements[A_Index-1])[Attribute], String) ; if the Attribute text is what we need
        return Elements[A_Index-1] ; return Element
}

Most of the time the .click() method will work but with the newest versions of IE I have seen a need to use other methods like dispatchEvent to make a mouseevent object

Usage example:

site := "ahkscript.org"

wb := ComObjCreate("InternetExplorer.Application")
wb.visible := true
wb.navigate(site)

while wb.readyState!=4 || wb.document.readyState != "complete" || wb.busy
    continue

links := wb.document.getElementsByTagName("A")

linkElement := LoopElements(links, "GNU General Public License", "innertext")

if (linkElement)
{
    msgbox % "Element found it was #" linkElement.sourceindex "`n`nLets click it!"
    linkElement.click()
}
else
    msgbox % "no Element found"
return



LoopElements(Elements, String, attribute="title")
{
try
Loop % Elements.Length ; check each element
    If instr((Elements[A_Index-1])[Attribute], String) ; if the Attribute text is what we need
        return Elements[A_Index-1] ; return Element
}

You can also call the function the onclick event is doing but try this first then later you can try other ways as you get the need...

Hope it helps
