my submit button is disable i want to enable once date and location field has been entered i have tried function but no luck `function testFinish(){
var datepicker = document.getElementById('datepicker');
var location = document.querySelector('location');
var btn = document.getElementById('btn');
if (location.value && datepicker.value)
btn.disabled = false;
}`
CodePudding user response：
You had bunch of errors in your code. First your selector for location input was wrong. you need to provide an id and then get the element by the id.
you could also do that with class selector but that will confuse you more.
<input id="location" type="text" placeholder="location" onkeyup="testFinish();">
var location = document.querySelector('#location');
secondly you need to add event listener to the datepicker input as well (in case the user fills the location first and date picker later, the button will still be disabled.)
<input type="text" onchange="testFinish()" id="datepicker" style="width: 120px;" autocomplete="off" placeholder="Date" readonly />
Below is the working snippet.
function testFinish(){
var datepicker = document.getElementById('datepicker');
var location = document.querySelector('#location');
var btn = document.getElementById('btn');
if (location && location.value && datepicker.value)
btn.disabled = false;
