I created a function in javascript, where it changes the number of options in the select according to the value that I selected in the previous select. This works normally on the computer, however when I use it on my phone and other people's, this function does not work
these are the selects:
<select class='opcoes' id="pecasDoJogo-1Auto" onchange="getValue('pecasDoJogo-1Auto')" onclick="changeQuantityOfOptions('pecasDoJogo-1Auto','pecasDoJogo-1TeleOp')">
<option value="0" >0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
</select>
<select class='opcoes' id="pecasDoJogo-1TeleOp" onchange="getValue('pecasDoJogo-1TeleOp')" onclick="changeQuantityOfOptions('pecasDoJogo-1TeleOp','pecasDoJogo-1Auto')">
<option value="0">0</option>
<option value="1" >1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
</select>
These are the functions I'm using:
function getValue(nameId){
return parseInt(document.getElementById(nameId).value)
}
function changeQuantityOfOptions(yourId,ReferenceId){
const quantidade = 9 - parseInt(document.getElementById(yourId).value)
const select = document.getElementById(ReferenceId)
select.innerHTML = ""
for(var i = 0; i <= quantidade; i ){
select.innerHTML = `<option value="${i}">${i}</option>`
}
}```
CodePudding user response:
You should call your function only onchange
, not onclick
.
function getValue(nameId){
return parseInt(document.getElementById(nameId).value)
}
function changeQuantityOfOptions(yourId,ReferenceId){
const quantidade = 9 - parseInt(document.getElementById(yourId).value)
const select = document.getElementById(ReferenceId)
select.innerHTML = ""
for(var i = 0; i <= quantidade; i ){
select.innerHTML = `<option value="${i}">${i}</option>`
}
}
