So i needed to pass a variable to the script tag in the ejs file. it's question array (i called it object in the var name for no reason), that i need to work with in the script tag. i saw that it's done by '<%-varname%>' .
But the thing is, i want to remove stuff from the array while working with it, so i need a copy of this array. And here is the problem:
console.log('<%-passedUser.questionsObject%>')
console.log('<%-passedUser.questionsObject[0]%>')
arrayToUse = '<%-passedUser.questionsObject%>'
console.log(arrayToUse)
console.log(arrayToUse[0])
question1,answer1,answer2,answer3,answer4,answer5,q2,answer1,answer2
question1,answer1,answer2,answer3,answer4,answer5
question1,answer1,answer2,answer3,answer4,answer5,q2,answer1,answer2
q
I tried JSON.stringify, parse, nothing works. i'd appreciate any help.
Note: i don't know why '<%-passedUser.questionsObject%>' isn't logging the correct way, but it's giving correct values. It's true form is :
[[question1,answer1,answer2,answer3,answer4,answer5],[q2,answer1,answer2]]
you have to use both json parse and json stringify
arrayToUse = JSON.parse('<%- JSON.stringify(passedUser.questionsObject)%>')
later you can easily split the array using
const [questions,answers] = arrayToUse
or do it before sending it to the client
<% const [questions,answers] = passedUser.questionsObject %>
<script>
const arrayToUse = JSON.parse('<%- JSON.stringify(questions)%>')
</script>
