Unable to type and extract value on web page

Posted on by jadenkim

Hello Experts,

i want to type a value into a textbox and extract a value from webpage.

it is very simple but PAD cannot recognize the textbox.

i used a web recorder to do it. it recorded well but didn't work with error below

"Subflow_2 3 Failed to write text '1234567890' in form field (error in communication with browser). "

it's selector is defined using UI element button. "iframe[Id="txppIframe"] input[Id="bsno"]"

here is the website and there is only one textbox on it.

https://teht.hometax.go.kr/websquare/websquare.html?w2xPath=/ui/ab/a/a/UTEABAAA13.xml

you can type 1234567890 into textbox then press enter. that's all i did with PAD.

before changing GA, it worked fine. but now i cannot.

i've tried to do it with UIPath and Winautomation. it worked perfectly but PAD didn't.

It would be much appreciated if you could give me an advise.

You may try to focus on the text box first, then entering the text. I have found some fields need that initial focus before you can enter the data. I do this a lot with iframe actions.

Hi @jadenkim ,

Try using 'Run Javascript function on web page' action

function ExecuteScript() {
var value = document.getElementById('grid2_cell_0_1').childNodes[0].textContent;
return value;
}

Hope this solves your issue.

Thanks 🙂
