IE.au3 and Javascript :Wait page AND javascript fully loaded

7 posts in this topic

#1 ·  Posted (edited)

Hi guys.

First of all, i hope u will understand my problem as i'm French and i'm not very good in English.

I got a trouble with my simulation.

I want to create a script that do some actions on a webpage. I use IE.au3, but the page is a full javascript application, so when IE is fully loaded (and _IELoadWait() ends) some content is still created dynamically by Javascript.

Before i can do my job and click on a button with DOM functions, i need to really WAIT javascript's work is finished.

Is there a way to do it?

Thx for ur help,

Tim

Is there a way to do it?

I doubt it. Here are two things that MIGHT work:

Look around the page and find an element that is dynamically created.

Then, using IE.au3, continuously poll for data about this element. When it succeeds/gives-empty data, you know the page exists and the Javascript is loaded, as Javascript created that element in the first place.

Option 2:

Use a hard coded timer or user input. This may work depending on the complexity of the javascript, operating environment etc.

I currently use your option 2 with sleeps, but i want to do better as i need to make a general solution (because i generate these simulations automatically and don't know how many sleeps i need to put in seach simulation).

Furthermore, i need to get the exact time the simulation takes (monitoring/supervision task) and with sleeps i can't have a good timer.

Your option 1 would be great but like in my first sentence i must do as if i didn't know the relevant page. Hence i can't say ok i wait for THIS element to be load. But maybe is it possible to add myself an element at the end of the page with Javascript and wait for him to answer? I don't think so cause he will be inserted by another Javascript thread regardless to the javascript running by IE, but maybe someone can have an idea.

So you know enough about the pages to be able to manipulate them after they are loaded, but not enough to know what dynamic elements you can look for on the page? This sounds strange - perhaps you need to explain in more detail.

There is no general answer to your question. The Ajax processing is asyncronous and there is no way for the browser to know whether it is complete or not. You'll need to apply your knowledge about the pages to devise a scheme that works for you.

Would it be possible to get the HTML source every second or so and search the source (string) for whatever dynamic elements are available?

I mean i can manipulate the page after she is loaded because my scenario does it. But This scenario is generated by a robot. The human (who don't know anything about Autoit) say : I want to do this and this on this page.So my scenario does these actions after the page is loaded.That could work if i asked my user to say to my robot : "The last element loading is ..." but generally he won't be able because he dosn't know anything in development.

That's why i asked a 'general solution' so that my robot wait with _IeLoadWait and do some actions to verify the page is well loaded and then do what the user asked.

But it seems impossible so i'll open a support for each scenario : If there is a problem i'll correct the scenaio manually myself.

Edit : Or something i could do using GMK idea is : The first time scenario is launch, he wait some time with Sleep() for example, each second he get the DOM source and see which element is the last (or at least in the lasts), write it and then use this element next.

      For the below form, I am able to automate using below code for textboxes.

      #include <IE.au3> Local $oIE = _IEAttach("http://localhost:18170/MartAdmin/", "url") _IELoadWait($oIE) $Search = _IEGetObjById($oIE,"x-auto-16-input") _IEPropertySet($Search, 'innerText','Uday KIran') $Search = _IEGetObjById($oIE,"x-auto-18-input") _IEPropertySet($Search, 'innerText','Uday KIran') But for the Login button, there is no id or name.
      The html code when I click on Inspect element in browser, shown below.
      <button tabindex="0" class="x-btn-text" style="width: 64px; position: relative;" type="button">Log In</button> Please let me know how to click this.?

      I am trying to script the opening of multiple tabs in IE with each tab having a separate login/password. I have been able to make a successful script that will open 3 separate IE sessions with the correct webpage and login or a script that will open 3 tabs in one session (which I want) but will not login. I have tried _IECreate, IEAttach etc. This is the script I am currently using . 
      #include <IE.au3> Const $navOpenInNewTab = 0x0800 Dim $oIE = _IECreate('http://asag.xxxxxxx.com/AAAA/index.htm') ;$o_IE.Navigate2('http://asag.xxxxxxx.com/apps/yyyyyyy/LogInSAG/login.asp', $navOpenInNewTab) ;$o_IE.Navigate2('http://asag.xxxxxxx.com/apps/yyyyyyy/LogInSAG/login.asp', $navOpenInNewTab) Call ("YYYYYYYSignIn") Func YYYYYYYSignIn () Local $username = _IEGetObjByName ($oIE,"uname") Local $password = _IEGetObjByName ($oIE,"pword") $oIE.Navigate2('http://asag.xxxxxxx.com/apps/xxxxxxx/LogInSAG/login.asp',2048) _IEFormElementSetValue ($username, "xxxxxxx") _IEFormElementSetValue ($password, "xxxxxxx") Send('{Enter}') EndFunc Call ("xxxxxxxSignIn") Func xxxxxxxSignIn () __IENavigate($oIE, "https://soa1gui.xxxxxxx.biz/gateway/NFServlet;jsessionid=1E3B8F6520DE0A1EC914A8ABB7E86341?NFH_MessageId=&NFH_Page=%2fpages%2fsearch%2fsearch.jsp", 1, 0x800) Local $domain = _IEGetObjByName ($oIE,"NF_CustomerID") Local $User_Name = _IEGetObjByName ($oIE,"NF_UserName") Local $Password = _IEGetObjByName ($oIE,"NF_Password") _IEFormElementSetValue ($domain, xxxxxxx") _IEFormElementSetValue ($User_Name, "xxxxxxx") _IEFormElementSetValue ($Password, "xxxxxxx") ;Send('{Enter}') EndFunc

      How can I check if element is focused in Firefox using FF.au3 UDF?
      This is my try:
      I have prepared a function that checks if the object is focused:
       
      _FFCmd('FFau3.isfocused=function isfocused(a){try{return (a === document.activeElement)}catch(e){return}}') $oElm = _FFXPath("//*[@id='someId']") ConsoleWrite(_FFIsFocused($oElm)) Func _FFIsFocused($sElement = "") Local $isFoc = _FFCmd("FFau3.isfocused(" & $sElement & ")") Return $isFoc EndFunc ;==>_FFIsFocused Now, the javascript part is tested and it does return successfully.
      After a lot of try/fails I inserted an alert box in order to display the object being compared.
      Here is what I got
       
      The focused object is: [object XULElement]
      The object that I send for comparing is [object HTMLInputElement]
      Why is that?

      Internet Explorer 11, AutoIt 3.3.14.2
      I want to download many files which are published with hyperlink on a web page. I use AutoIt and when there is a few files, it works even if It's on a website with secured links.
      I have a script to download link items with the object method (I gave a partial sample), but when the number of link exceed the web page, there is not an auto scroll, then the links which are not on displayed without scroll are not downloaded.
      Thank you
      From France
