Chrome.ahk Getting stuck on Evaluate() in a loop

[Penguin]

Hi all,
I'm running into some trouble reading a table with Chrome.ahk in a loop. It seems to randomly stop in the loop and different spots and never get through the entire loop. I have a function that is writing to a txt file and the code stops at PageInstance.Evaluate(some Java Script).value. I see the log file write the retrieving message, but not the retrieved message. The loop does not continue and no errors are thrown.

Any help would be great

Here's my code

Code: Select all

getJobNumberURLs(iframeRef) {
	iframeRef := "document.getElementsByClassName('isView reportsReportBuilder')[0].contentWindow."
	sleep, 5000
	PageInstance := Chrome.GetPageByTitle("Parse Report", "StartsWith")

	js := iframeRef "document.getElementsByClassName('data-grid-table data-grid-full-table')[0].rows.length"
	rowCount := PageInstance.Evaluate(js).value
	PageInstance.Disconnect()

	loopCount := rowCount -2
	loop %loopCount%
	{
		PageInstance := Chrome.GetPageByTitle("Parse Report", "StartsWith")
		PageInstance.WaitForLoad()
		PageInstance.Call("Console.enable")
		
		if (!IsObject(PageInstance)) {
		  MsgBox Not A Page Object
		}
		
		progressBarPercent := A_Index * (100 / loopCount)
        Progress, %progressBarPercent%, File Wait Status , %A_Index%  of  %loopCount%, File Wait
		sleep 1000

		jobNumberJS := iframeRef "document.getElementsByClassName('data-grid-table data-grid-full-table')[0].rows[" A_Index "].cells[1].innerText"
		
		WriteToLogFile("Retrieving Job Number " A_Index)
		jobNumber := PageInstance.Evaluate(jobNumberJS).value
		if (StrLen(jobNumber) < 1) {
			MsgBox Failure 1
		}
		WriteToLogFile("Retrieved Job Number " A_Index)
		
		jobNumberLinkJS := iframeRef "document.getElementsByClassName('data-grid-table data-grid-full-table')[0].rows[" A_Index "].cells[1].querySelector('a').href"
		WriteToLogFile("Retrieving Job Link " A_Index)
		jobNumberLink := PageInstance.Evaluate(jobNumberLinkJS).value
		if (StrLen(jobNumberLink) < 1) {
			MsgBox Failure 2
		}
		WriteToLogFile("Retrieved Job Link " A_Index)
		
		taskNumberJS := iframeRef "document.getElementsByClassName('data-grid-table data-grid-full-table')[0].rows[" A_Index "].cells[2].innerText"
		WriteToLogFile("Retrieving Task Number " A_Index)
		taskNumber := PageInstance.Evaluate(taskNumberJS).value
		if (StrLen(taskNumber) < 1) {
			MsgBox Failure 3
		}
		WriteToLogFile("Retrieved Task Number " A_Index)
		
		taskNumberLinkJS := iframeRef "document.getElementsByClassName('data-grid-table data-grid-full-table')[0].rows[" A_Index "].cells[2].querySelector('a').href"
		WriteToLogFile("Retrieving Task Link " A_Index)
		taskNumberLink := PageInstance.Evaluate(taskNumberLinkJS).value
		if (StrLen(taskNumberLink) < 1) {
			MsgBox Failure 4
		}
		
		typeJS := iframeRef "document.getElementsByClassName('data-grid-table data-grid-full-table')[0].rows[" A_Index "].cells[7].innerText"
		WriteToLogFile("Retrieving Job Type " A_Index)
		jobType := PageInstance.Evaluate(typeJS).value
		if (StrLen(jobType) < 1) {
			MsgBox Failure 5
		}
		WriteToLogFile("Retrieved Job Type " A_Index)
		
		jobNumberLink := StrReplace(jobNumberLink, ".", "`.")
		taskNumberLink :=  StrReplace(taskNumberLink, ".", "`.")
		jobEntry := jobNumber ", " jobNumberLink ", " taskNumber ", " taskNumberLink ", " jobType
		FileAppend, %jobEntry% `n, C:\Users\parse\Desktop\ParsingFiles\Jobs.csv
		
		PageInstance.Disconnect()
	}

	return
}

I will add it seems to happen once we get about 6 in our loop

try this
it work for me

in chrome.ahk version 1.2

line 227
Call(DomainAndMethod, Params:="", WaitForResponse:=True)
{
....
....
; Wait for the response
this.responses[ID] := False
i:=0
while (!this.responses[ID]) {
if(i>100){
this.ws.Send(Chrome.Jxon_Dump({"id": ID
, "params": Params ? Params : {}
, "method": DomainAndMethod}))
i:=0
}
Sleep, 50
i++
}
....
....
}
