Weird code function

i have a problem with the i < (long code) the problem is it doesn't take the number so for example if a put it to i < 4 it works but the other way doesn't here's the code: <form action=""> <input type="number" name="elements" class="input" placeholder="Number Of Elements" /> <input type="text" name="texts" class="input" placeholder="Elements Text" /> <select name="type" class="input"> <option value="Div">Div</option> <option value="Section">Section</option> </select> <input type="submit" name="create" value="Create" /> <div class="results"></div> </form>

let numberOfElements = document.querySelector("[name='elements'")
let elementsText = document.querySelector(`[name='texts'`)
let elementsType = document.querySelector("[name='type'")
let createBtn = document.querySelector("[name='create'")
let results = document.querySelector(".results")
// Creation

let valueHolder = numberOfElements.addEventListener("input",() => numberOfElements.value)


createBtn.addEventListener("click",function (preventor) {
  for (let i = 0 ;i < numberOfElements.addEventListener("input",() => numberOfElements.value) ;i++) {
  let divCreation = document.createElement("div")
  results.appendChild(divCreation)
}
preventor.preventDefault()
}
)

let numberOfElements = document.querySelector("[name='elements'")
let elementsText = document.querySelector(`[name='texts'`)
let elementsType = document.querySelector("[name='type'")
let createBtn = document.querySelector("[name='create'")
let results = document.querySelector(".results")
// Creation

let valueHolder = numberOfElements.addEventListener("input",() => numberOfElements.value)


createBtn.addEventListener("click",function (preventor) {
  for (let i = 0 ;i < numberOfElements.addEventListener("input",() => numberOfElements.value) ;i++) {
  let divCreation = document.createElement("div")
  results.appendChild(divCreation)
}
preventor.preventDefault()
}
)

محمدOP•5mo ago

sorry i didn't understand

lko•5mo ago

```js code ``` Ayways what do you think this do?

 numberOfElements.addEventListener("input",() => numberOfElements.value)

 numberOfElements.addEventListener("input",() => numberOfElements.value)

محمدOP•5mo ago

i have an input in the html and this should get its value

محمدOP•5mo ago

I'm trying to do like this

lko•5mo ago

No, .addEventlistener creates a listener, in your case of the input, so you're basically saying if i is less than listener, which doesnt make any sense, listener is not a number

محمدOP•5mo ago

yes that's why there's a .value at the end of it so i only get the value out of it

lko•5mo ago

Yes but it doesnt return the value

محمدOP•5mo ago

why

lko•5mo ago

because addEventListener just creates a listener, doesnt return anything

محمدOP•5mo ago

ok then do i do it i need a method that gives me the live value of the input and addEventListener is the only one who can do it like this

let numberOfElements = document.querySelector("[name='elements']") // added missing ']'
let elementsText = document.querySelector(`[name='texts']`) // again
let elementsType = document.querySelector("[name='type']") // again
let createBtn = document.querySelector("[name='create']") // again
let results = document.querySelector(".results")

createBtn.addEventListener("click", (e) {
    e.preventDefault()
    const numberOfElements = numberOfElements.value
    for (let i = 0; i < numberOfElements; i++) {
      let divCreation = document.createElement("div")
      results.appendChild(divCreation)
    }
})

let numberOfElements = document.querySelector("[name='elements']") // added missing ']'
let elementsText = document.querySelector(`[name='texts']`) // again
let elementsType = document.querySelector("[name='type']") // again
let createBtn = document.querySelector("[name='create']") // again
let results = document.querySelector(".results")

createBtn.addEventListener("click", (e) {
    e.preventDefault()
    const numberOfElements = numberOfElements.value
    for (let i = 0; i < numberOfElements; i++) {
      let divCreation = document.createElement("div")
      results.appendChild(divCreation)
    }
})
