Questions & Help

Hi
Can someone give me a hint or example script how to get a value from table in a HTML page?
I have found that I have to use the fetch() function, but have not found an example how to extract the value from the variable.

Maybe this example could help

var test = await fetch('http://gmcmap.com/historyData-plain.asp?Param_ID=44549586449&timezone=1');
const html = await test.text();
const data = JSON.parse(html.match(/\{.+?\}/s)[0]);
return data.CPM
