I am currently modifying a text editor and I have the task of selecting text for manipulation using JavaScript. Can you provide guidance on how to select text using Cucumber, Capybara, and Selenium?
I came across a helpful stackoverflow post discussing how to utilize JavaScript for text selection.
Can you set and/or change the user’s text selection in JavaScript?
After tweaking the script to work within Selenium IDE's getEval function, I managed to exclude non-essential code for Firefox compatibility:
function selectElementContents(el,start,end) {
var sel = window.getSelection();
var range = window.document.createRange();
range.setStart(el,start);
range.setEnd(el,end);
sel.removeAllRanges();
sel.addRange(range);
}
selectElementContents(window.document.getElementById("container").firstChild,10,20)
This method allows selecting a specific text range within an element by specifying its ID ("container") and character indexes (start at 10, stop at 20).
To simplify this into a single line for a Selenium getEval statement will achieve the desired text selection.
If single-element text selection isn't sufficient, delving into Javascript ranges documentation can provide additional insights.
Implementing Josh's approach in a custom Capybara helper function, with the added ability to specify optional position arguments for partial selections within the start/end elements:
module CustomTextSelection
def extract_text(startElement, endElement, startPosition = 0, endPosition = 0)
js = <<-JS
var selection = window.getSelection();
var textRange = window.document.createRange();
textRange.setStart(arguments[0], #{startPosition});
textRange.setEnd(arguments[1], #{endPosition});
selection.removeAllRanges();
selection.addRange(textRange);
JS
page.execute_script(js, startElement.native, endElement.native)
end
end
World(CustomTextSelection)
Subsequently, in your testing scenario:
starting_element = first('#first')
ending_element = first('#last')
extract_text(starting_element, ending_element)
