Right. I put the failed attempts in as comments to be comprehensive for others to see what I tried.

OIC... that wasn't clear to me at first.

@horphi Can you show us a working example?

horphi · May 18, 2018

It´s really simple.

The interaction with the frame will be automatically initiated by the web driver. You only need to pass the right ID of the Frame. On my page i have only 1 Frame and that means = 0.

_WD_Window($sSession, 'frame', '{"id":0}')
    $sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, '//p')
    _WD_ElementAction($sSession, $sElement, 'click')

What i try as next step is to select the text inside the Frame, but still no success... ;-)

I was reading the W3C specs the other day and it appears that you can also pass an element reference id. I will have to do some manual testing with this to confirm that it works as expected and that the value being returned by _WD_FindElement is correct.

I don´t know, why the WD does not return the string that i placed

1. i switch into the iframe

2.i execute the JS Script to receive the Text...

value is anytime NULL

Func _pasteIntoText() ;im Editor Texte markieren
    $sSearchtext = GUICtrlRead($Input1);--> document.getElementsByTagName('p')[0].innerHTML;
    $sStrategy = GUICtrlRead($Input2) ;--> empty

    _WD_Window($sSession, 'frame', '{"id":0}')

    $sElemtent = _WD_ExecuteScript($sSession, $sSearchtext, $sStrategy)

    _WD_Window($sSession, 'parent', '{"id":0}')
EndFunc   ;==>_pasteIntoText

<iframe allowfullscreen="true" src="javascript:false" style="width: 508px; height: 311px;" tabindex="3" frameborder="0">

  <head>
    <style>.ie * {min-height: auto !important} .ie table td {height:15px}</style>

You aren't returning a value from your script. Therefore, the result is null.

Your´re right...forgot to state "return"

return document.getElementsByTagName('p')[3].innerHTML;

__WD_Post: URL=HTTP://127.0.0.1:4444/session/b15514ad-6d2e-4c76-94b4-b35a542620b6/execute/sync; $sData={"script":"return document.getElementsByTagName('p')[3].innerHTML; ", "args":[]}
__WD_Post: StatusCode=200; ResponseText={"value":"[attach]"}

Did you tested to get a array back instead of a string? If i look for a specific value, then i need to execute the script several times, until i find the right one..

Or lets say, @ the END i will "select" the given value.

Normally:

return document.getElementsByTagName('p')[3].select;

--> but nothing happens... :-(

No, I haven't. Can you provide an example that shows what you are attempting to do?

P.S. If you are trying to return an array of elements, then you should look at _WD_FindElement

BobMerit · May 23, 2018

Have I found an error in the code? I am under the impression that WD_FindElement will return an array so I am assuming that part might work at least it was stated by the code author. But using $_WD_LOCATOR_ByClassName seems incomplete. WD_Post doesn't seem to have a clue how to process the request. My project is 90% complete and I can't get past this point. I have to find some way to generate a list of elements and somehow sequence through them. Thanks for any help.

$checkboxarray = _WD_FindElement($sSession, $_WD_LOCATOR_ByClassName, "x-tree-checkbox")

_ArrayDisplay($checkboxarray)

__WD_Post: URL=HTTP://127.0.0.1:4444/session/56d9c46d-6959-473b-980c-22830313d944/element; $sData={"using":"class name","value":"x-tree-checkbox"}
__WD_Post: StatusCode=400; ResponseText={"value":{"error":"invalid argument","message":"Unknown locator strategy class name","stacktrace":""}}
_WD_FindElement: {"value":{"error":"invalid argument","message":"Unknown locator strategy class name","stacktrace":""}}
_WD_FindElement ==> Webdriver Exception: HTTP status = 400

Danp2 · May 24, 2018

Not an error in the code, per se. Looking at the latest W3C specs, these are the only supported locator strategies --

Quote

State Keyword
CSS selector "css selector"
Link text selector "link text"
Partial link text selector "partial link text"
Tag name "tag name"
XPath selector "xpath"

So, passing one of the other locator constants will result in the error you received.

I'll need to do some research to determine if these need to be removed or if they are valid in other instances.

Actually, it will return an array, but only if $lMultiple is True. If not, then it returns a single element id.

Here's one way that you could try rewriting your code to use xpath --

$checkboxarray = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, ".x-tree-checkbox", "", True)
_ArrayDisplay($checkboxarray)

BobMerit · May 24, 2018

I certainly appreciate your response. It did change the error message. I seem to be pushing the limit of what can be done.

$checkboxarray = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, ".x-tree-checkbox", "", True)
_ArrayDisplay($checkboxarray)

Not really... just have to get the syntax right. I likely steered you in the wrong direction because that's actually a CSS selector. Try changing $_WD_LOCATOR_ByXPath to $_WD_LOCATOR_ByCSSSelector.

If that doesn't work, then you should probably share more details about the element(s) you are attempting to locate (show us the associated HTML).

BobMerit · May 24, 2018

Oooooo oooo oooo i got a bite. This might work.

$checkboxarray = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, ".x-tree-checkbox", "", True)
_ArrayDisplay($checkboxarray)

BobMerit · May 24, 2018

Thank you!! I was able to pick the array id from the $checkboxarray[1] and use that to check the box. I didn't think that was going to work at all. lol Huh Very interesting.

grzesiek · May 24, 2018

I tried the example code with chrome and received error when testing timeouts 'SetTimeout unknown error: 'ms' must be a double'.

Danp2 · May 24, 2018

@grzesiek Thanks for the report. I'll look into it when I have a moment.

Edit: This appears to be an issue with the ChromeDriver implemenation. See here for more details.

Hi,

i´m irritated

this works

_WD_ExecuteScript($sSession, 'return  document.getElementsByTagName('p')[1].innerHTML;')

__WD_Post: URL=HTTP://127.0.0.1:4444/session/fc4b43b3-2c7b-4ce1-92fb-660e2d017aab/execute/sync; $sData={"script":"return  document.getElementsByTagName('p')[1].innerHTML; ", "args":[[]]}
__WD_Post: StatusCode=200; ResponseText={"value":"test2"}
_WD_ExecuteScript: {"value":"test2"}

But this not LINK

_WD_ExecuteScript($sSession, 'document.getElementsByTagName('p')[1].select;')

__WD_Post: URL=HTTP://127.0.0.1:4444/session/fc4b43b3-2c7b-4ce1-92fb-660e2d017aab/execute/sync; $sData={"script":" document.getElementsByTagName('p')[1].select; ", "args":[[]]}
__WD_Post: StatusCode=200; ResponseText={"value":null}
_WD_ExecuteScript: {"value":null}

Can someone explain to me what i don´t understand again???

Many thanks

horphi

Danp2 · May 24, 2018

@horphi It's not clear what you are trying to accomplish. Please state your goal so that we can better assist you.

P.S. Please post your general support questions in this thread --

grzesiek · May 24, 2018

@horphi

Try this:

_WD_ExecuteScript($sSession, 'document.getElementsByTagName('p')[1].select();')

State	Keyword
CSS selector	"`css selector`"
Link text selector	"`link text`"
Partial link text selector	"`partial link text`"
Tag name	"`tag name`"
XPath selector	"`xpath`"
