Bootstrap radio button isn't working in flask
I am using Bootstrap 4 radio button radio button in a flask application. and below is the snippet I used
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-outline-secondary">
<input type="radio" onclick="javascript:toggleElements();" name="toggle" id="twitter"/> Twitter
</label>
<label class="btn btn-outline-secondary" >
<input type="radio" onclick="javascript:toggleElements();" name="toggle" id="facebook"/> Facebook
</label>
</div>
and the javascript code
<script type="text/javascript">
function toggleElements() {
alert('hurray');
if(document.getElementBId('twitter').checked) {
document.getElementById('twitterrows').style.display = 'block';
document.getElementById('facebookrows').style.display = 'none';
}
if(document.getElementById('facebook').checked) {
document.getElementById('facebookrows').style.display = 'block';
document.getElementById('twitterrows').style.display = 'none';
}
}
</script>
Initially,I tried with simple html radio buttons and was able to trigger Javascript function toggleElements(). However, after replacing the normal radio buttons with the bootstrap radio, nothing is triggered.
Below is the entire html code
{% from 'helper/forms.html' import render_field with context %}

I strongly suspect with the order of scripts being called under the head tag. Can someone help me to fix this please.

I fixed it by replacing the three script tags in the above html page with the below
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script>

- make sure you have included the correct version of bootstrap. Please check if there is any error in the browser console.
- https://getbootstrap.com/docs/4.4/components/input-group/#checkboxes-and-radios.
- I am suspecting that the javascript click is not properly binded to the click event.
