I need to store the value of <select>
into local storage, however, I cannot do this I assume that is because the <option>
of this <select>
was dynamically added and I should handle it in a higher level. But I don't know how to do this.
html
<select id="months" name="months">
<option value='january'> January </option>
<option value='february'> February </option>
<option value='march'> March </option>
<option value='april'> April </option>
<option value='may'> May </option>
<option value='june'> June </option>
<option value='july'> July </option>
<option value='august'> August </option>
<option value='september'> September </option>
<option value='october'> October </option>
<option value='november'> November </option>
<option value='december'> December </option>
</select>
<select id="days" name="days"></select>
js
// dinamically add days
const $months = document.getElementById('months')
const $form = document.getElementById('form')
function dayOfMonthOne() {
for (let i = 1; i < 32; i ) {
const days = `
<option>${i}</option>
`
const $days = document.getElementById('days')
$days.innerHTML = $days.innerHTML days
}
}
function dayOfMonthZero() {
for (let i = 1; i < 31; i ) {
const days = `
<option>${i}</option>
`
const $days = document.getElementById('days')
$days.innerHTML = $days.innerHTML days
}
}
function dayOfMonthEight() {
for (let i = 1; i < 29; i ) {
const days = `
<option>${i}</option>
`
const $days = document.getElementById('days')
$days.innerHTML = $days.innerHTML days
}
}
$months.addEventListener('change', function(){
switch ($months.value) {
case 'january':
$months.value = 'january'
dayOfMonthOne()
break
case 'february':
$months.value = 'february'
dayOfMonthEight()

})
const $days = document.getElementById('days')
$days.addEventListener('change', function(){
const dVal = $days.options[$days.selectedIndex].text
localStorage.setItem('day', dVal)
})
CodePudding user response:
It looks like you need to modify how you're accessing the $days
properties:
const dVal = $days[$days.selectedIndex].text
or even more simply:
const dVal = $days.value
ie, remove .options
Further enhancements would be to create a single function for rendering the days
options instead of a giant switch
statement that uses multiple functions.
You will also want to trigger that function on pageload so that January gets populated.
