How to run jquery or javascript with WebUI.executeJavaScript

Product Forums Katalon Studio

Hi there,
I’m starting with katalon, and I can not get these script to run, or it shows an error or returns null, even though executing the script from the browser and executes correctly, I want to know how many “tr” there are in the Table

System.out.println(WebUI.executeJavaScript(“\$(‘#gridEmpresas tbody tr’).length > 0”))

or

//System.out.println(WebUI.executeJavaScript(“document.getElementById(‘gridEmpresas’).getElementsByTagName(‘tr’)”, null))

I accept suggestions,

regards

<table id="gridEmpresas"> <tbody>
   <tr>
     <td>1st text</td>
   </tr>
   <tr>
     <td>2nd text</td>
   </tr>
   <tr>
     <td>N text</td>
   </tr> <tbody></table>
2

This should bring up an alert dialog with 3 in it.

WebUI.executeJavaScript("alert(document.getElementById('gridEmpresas').getElementsByTagName('tr').length)", null)

This should place 3 in the variable len:

def len = WebUI.executeJavaScript("document.getElementById('gridEmpresas').getElementsByTagName('tr').length", null)

Hope that helps

present: FAILED because (of) Unable to execute JavaScript. (Root cause: org.openqa.selenium.JavascriptException: TypeError: document.getElementById(…) is null
don´t works but solve the problem with this way

WebDriver driver = DriverFactory.getWebDriver()

WebElement Table = driver.findElement(By.id(‘gridServicios’))

List rows_table = Table.findElements(By.tagName(‘tr’))

int rows_count = rows_table.size()

I have problem when I set value in a field text by using this command
String js = “”"
var clientTextField = document.querySelector("#PolarisTextField2");
clientTextField.value = ‘1000’;
clientTextField.onchange();
“”"
WebUI.executeJavaScript(js, null)
when I run this code , Katalon show the error like this
=============== ROOT CAUSE =====================

Caused by: org.openqa.selenium.JavascriptException: javascript error: clientTextField.onchange is not a function

The message tells you what you need to look at:

Caused by: org.openqa.selenium.JavascriptException: javascript error: clientTextField.onchange is not a function

So, you should remove the line that calls onchange():

String js = """
var clientTextField = document.querySelector("#PolarisTextField2");
clientTextField.value = ‘1000’;
// clientTextField.onchange();
"""
WebUI.executeJavaScript(js, null)

HTML Element does not have onchange function.
