element.value and fireEvent still won't work in VUE or React

[wolfccb]

Thank you very much for this great project! I am working with a VUE (or React, or both, not sure) login form in Chrome, and tried the following code in VBA:

Set userName=chrome.getElementsByQuery("input[class='el-inputinner']")(1) Set passWord=chrome.getElementsByQuery("input[class='el-inputinner']")(2) Set btnLogin=chrome.getElementsByQuery("button[type='button']")(1) userName.value="testuser" userName.fireEvent ("input") passWord.value="password" passWord.fireEvent ("input") btnLogin.click

I can see from the Chrome page that the values have been correctly shown in the form, and the InputEvents have been successfully triggered (which behave just like I dispatch the events in Chrome console). The btnLogin.click works, too.

But the webpage still tells me that both userName and passWord are empty. This can be solved by clicking the values in the input boxes. I tried some methods in console such as userName.focus(), .click(), or dispatch several events, the problem still exists.

I know that you have made a Sendkeys method, but unfortunately I have to make my VBA run with Task scheduler, which means it is hidden.

Is there a way to simulate user input?

Thank you and good luck!

Hi there, thanks for the comment. Are you able to reproduce the problem somewhere that I can test on? And how come you are unable to use the SendKeys method with running VBA from Task Scheduler?

Thanks for the quick reply. I am afraid I am not able to put it online because it's an intranet website. As for task scheduler, if we want it to run a task even when user is not logged in Windows, we have to tell Windows password to it, and it will run the task invisibly. There seems no option on this behavior. I searched a lot during the past days and tried in Chrome console, but I still cannot login the website in automated way, not even in console. Any suggestion is appreciated. Thanks again!

I am not an expert, but have you tried to set the innerText property instead of value? Sometimes this works for me.

It is hard for me to help you since the issue is not recreatable for me to test. Anyway at best I can only suggest the followings:

• Carefully review the html structure of that input element and its siblings to see if you are also meant to send value any other hidden elements to fully trigger the data input of that field.
• Test if the SendKey method works. If it does, try to creatively redesign your solution to allow the execution of the method and walk-around the resitrictions.

Thanks @longvh211 @MitsOmitsaras . Problem solved. Here it is:

Set userName=chrome.getElementsByQuery("input[class='el-inputinner']")(1) Set passWord=chrome.getElementsByQuery("input[class='el-inputinner']")(2) Set btnLogin=chrome.getElementsByQuery("button[type='button']")(1) userName.value="testuser" userName.fireEvent ("focus") userName.fireEvent ("input") userName.fireEvent ("change") userName.fireEvent ("blur") passWord.value="password" passWord.fireEvent ("focus") passWord.fireEvent ("input") passWord.fireEvent ("change") passWord.fireEvent ("blur") btnLogin.click

It seems this website requires such series of event to validate user input. Maybe it's a good idea to add some notes to the project demo.

Good luck!

Thanks a lot for the update buddy. It is unusual to require that many events for just a single input field. Usually only one among those should be enough (such as "change" or "blur") I think.
