I am trying to get data from an API and edit the endpoint based on the selected value from a dropdown and show the respective chart for it, can I integrate js, jQuery and charts all together? Below is my code where I tried this:
async function bruh(){
$( document ).ready(function() {
$('select').on('change', async function() {
this.value = this.value.toLowerCase();
const apiUrl = 'https://api.covidtracking.com/v1/states/'+this.value+'/daily.json';
const response = await fetch(apiUrl)
const barChatData = await response.json()
console.log(barChatData)
const positive = barChatData.map((x) => x.positive)
const date = barChatData.map((x) => x.date)
positives = positive
dates = date
});
})
}
async function dummyChartbruh() {
await bruh()
const ctx = document.getElementById('yourChart').getContext('2d');
const chart = new Chart(ctx, {
type: 'line',
data: {
labels: dates,
datasets: [{
label: 'Positive',
backgroundColor: 'blue',
borderColor: 'rgb(255, 99, 132)',
data: positives,
fill: false
}
]
},
options: {
tooltips: {
mode: 'index'
}
}
})
document.getElementById("yourChart").removeAttribute("hidden");
$('#yourChart').show()
}
dummyChartbruh()

However it does not display any values on the chart when the dropdowns are changed, how do I correct this?
