I am a complete newbie at JS and currently using it in a testing capacity along with the Karate framework to perform some UI testing. I am having the following problem:
There is a dropdown that has the following HTML:
<select class=id="CarId" name="CarId" aria-describedby="CarId-error" aria-invalid="false" xpath="1">
<option value="1">Mercedes</option>
<option value="2">BMW</option>
<option value="3">Lexus</option>
<option value="4">Honda</option>
<option value="5">Toyota</option>
<option value="6">VW</option>
</select>
I used the following Karate method to get all text values under the dropdown:
def grabValues = scriptAll('#CarId', '_.textContent')
Once printed, the array look like this:
[
"Mercedes\nBMW\nLexus\nHonda\nToyota\nVW\n"
]
console.log(Math.floor(Math.random() * (grabValues.length-1)))
When printed, it keeps giving me 0.0. I am assuming this is because the array contains new lines vs comma delimitated? If so, how can I get rid of the new lines and replace with commas?
What you want is to get the text from each <option>
def grabValues = scriptAll('#CarId option', '_.textContent')
This will give you an array of text values like
["Mercedes","BMW","Lexus","Honda","Toyota","VW"]
To get a random index you would use
Math.floor(Math.random() * grabValues.length)
One line code is console.log(myArr[0].split('\n'))
OR
Let's assume : The array of String is stored in myArr
let myArr = ["ABC\nDEF\nGHI\nJKL\nMNO\nPQR\nSTU\nVWX\nYZA\n"]
To get the string from the array
let stringOfArr = myArr[0]
Storing the new array from the stringOfArr deleminated by '\n' in newArray
let newArray = stringOfArr.split('\n')
console.log(newArray)
