4,258 PointsSimple clear or reset form on JavaScript
Can anyone tell me what's wrong with my code I keep getting error:main.js:43 Uncaught TypeError: Cannot read property 'reset' of null at clearIt (main.js:43) at HTMLInputElement.onclick (index.html:59)
I want to reset the form with a clear button.
This is the JavaScript: function getJson(){ let city = document.querySelector('#city').value; let zip = document.querySelector('#zip').value; document.querySelector('#city-title')
fetch(`http://api.openweathermap.org/data/2.5/weather?q=${city}&zip=${zip}&appid=186a445ce8d24b03d24996a4ab982100&units=imperial`)
.then(response => response.json())
.then(rawData =>{
console.log(rawData)
let high = `${rawData.main.temp_max}\u00B0F`
let display_high = document.createElement('w1')
display_high.innerHTML = high
document.querySelector('#high').append(display_high)
let low = `${rawData.main.temp_min}\u00B0F`
let display_low = document.createElement('w1')
display_low.innerHTML = low
document.querySelector('#low').append(display_low)
let forecast = rawData.weather[0].main
let display_forecast = document.createElement('w1')
display_forecast.innerHTML = forecast
document.querySelector('#forecast').append(display_forecast)
let humidity = `${rawData.main.humidity}%`
let display_humidity = document.createElement('w1')
display_humidity.innerHTML = humidity
document.querySelector('#humidity').append(display_humidity)
})
} function displayCity(){ let city = document.querySelector('#city').value; let display_city = document.createElement('w2') display_city.innerHTML = city.charAt(0).toUpperCase()+ city.slice(1) document.querySelector('#city-title').append(display_city)
} var weather = 0; function clearIt(){ document.querySelector ("getJson").reset(); weather = 0; }
This is the html: <input type="button" value="Clear" onclick="clearIt()">

would look for a tag name of "getJson", and since that's not a valid HTML tag name, that's probably the issue or at least part of it.
But you don't need JavaScript to implement a reset button, since that's a built-in feature of a form. Just include this somewhere inside the form:
<input type="reset">
