问题
I'm writing a ruby webdriver test that needs to store a dynamic value such as an order ID to use later on in the text. I think I need to extract the value from the string and then store it as a variable to call for future use.
The string looks like this and I just need to extract/store the numeric value.
<span class="receiptNum hidden-xs">Receipt #: 12303430</span>
Any tips or examples on how to extract that value and create a variable for future use would be great!
回答1:
To extract the text (only numbers) out of the this element, try using the following code:
@numbers = @driver.find_element(:css=>'receiptNum').text.scan(\d+)
Currently I am saving this number in an instance variable which can be used again in the same test as it will flow around with the test object till the test finishes.
Other option include saving it in a temp txt file and reading from it when required.
Note: Fetching data now and using it later is not a good practice, try not to use this very frequently.
Hope it helps!!!
