Waiting for XPath or CSS elements
Hi, What is the best strategy for waiting XPath and CSS elements to be displayed on a page? They are AJAX generated so I can't rely on page.Wait(). I need to achieve the following...
I usually do a code loop until the object is found or until some sort of safety timeout period is exceeded. I write in VBScript, but hopefully, you can see the intention and create something similar to suit your needs.
'We'll wait for ten seconds
curTime = aqDateTime.Now
endTime = aqDateTime.AddSeconds(curTime, 10)
'Start loop
Do
'Optional delay to space out the attempts to find the element
aqUtils.Delay 250
' QuerySelector will return object or Nothing/null
Set elementOb = Page.QuerySelector("whatever")
Loop Until Not elementOb Is Nothing Or aqDateTime.Compare(aqDateTime.Now, endTime) > -1
' Loops exits if the elementOb is a valid object (not Nothing) or we've passed the set end time
If elementOb Is Nothing Then Log.Error "Failed to find element object."
End Sub
