Scrolling to a Specific Area

If you need to scroll the web viewer to a specific area on the screen, you can use JavaScript.

Syntax: window.scrollTo( xpos, ypos )

Parameter Type Description

xpos	Number	Required. The coordinate to scroll to, along the x-axis (horizontal), in pixels
ypos	Number	Required. The coordinate to scroll to, along the y-axis (vertical), in pixels

In the following Scripting Engine code, we scroll to position 300px down and 100px right.

runScript("""window.scrollTo(100,300)""")

Scrolling by Specific Pixels

If you need to scroll the web viewer by specific pixels on the screen, you can use JavaScript.

Syntax: window.scrollBy( xnum, ynum )

Parameter Type Description

xnum	Number	Required. How many pixels to scroll by along the x-axis (horizontal). Positive values will scroll to the right, while negative values will scroll to the left
ynum	Number	Required. How many pixels to scroll by along the y-axis (vertical). Positive values will scroll down, while negative values scroll up.

In the following Scripting Engine code, we scroll by position 300px down and 100px right.

runScript("""window.scrollBy(100,300)""")

How to find how many pixels to scroll

You could likely do it on your pc. Open up the page you want to show in Chrome (or Edge) on your pc and hit F12. That should show Dev Tools (other browsers have similar stuff). Scroll the page to where you want it and then in the “Console” section of the Dev Tools type:

window.scrollY

That should show you how many pixels you have actually scrolled down. And you can use this value.

Deleting a Specific Element

runScript("""j("css_selector").remove();""")

Moving an Element to Body

runScript("""var elem = j("css_selector");j("body").append(elem);""")

Delete All Content Besides One Element

extract("""css_selector""")

Change the Background Color

runScript("""document.body.style.backgroundColor = "white";""")

Or you can use a hex color picker:

runScript("""document.body.style.backgroundColor = "#6217e5";""")

The #6217e5 is this color:

Selecting a Specific Option from a Dropdown List

runScript("""
a = document.querySelector('Dropdown_list's_CSS_Selector')
for (var i = 0; i < a.options.length; i++) 
{
if (a.options[i].text === '_DROPDOWN_VALUE_') 
{
a.selectedIndex = i;
break; 
}
}
""")

• _DROPDOWN_VALUE_ should be an option from the dropdown menu
