Error: Templates should only be responsible for mapping the state to the UI. Avoid placing tags with side-effects in your templates, such as <script>
I am using Vuejs and I keep getting this warning in the console. Also no data is loaded because of this warning. I checked the code for unwanted tags but did not find any.
Is this because of the javascript code or I have something wrong in my html?
Here is my code:
HTML
<div class="row">
<div class="col-sm-12" style="margin-top: 20px;">
<form class="form-inline" method="GET" action=".">
<div class="col-sm-3" style="float: right;"><h4>Date:</h4>
<input class="form-control" style="padding-bottom:0px;" type="text" id="datepicker" readonly="true" name="date" value="2016-06-30">
<input type="submit" class="btn btn-primary btn-sm" value="Submit" >
</div>
</form>
<div class="col-sm-2" style="float: right; margin-top:40px;">
<button class="btn btn-info" type="button" id="csv_export">Click to Export</button>
</div>
</div>
<div class="col-sm-12" style="margin:20px;">
<table class="table table-sm table-striped table-bordered" id="absent-list">

Answer
You can use script tag in this way and it will work fine.
I was facing the same problem when I used <script></script> tag without specifying its type.
After using the type attribute Vue did not warn me for critical error:
<script type="application/javascript">
// your code
</script>
