问题
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">

回答1:
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>
回答2:
I think the answer is in you question title. Just get rid of all the <script> tags in the template, put them outside of the template.
In this case you are using body as the template and you are putting scripts inside your template (body)
The easy solution is to change the el: 'body' to el: '#wrapper' and edit your html to
<body>
<div id="wrapper">
...
</div>
<script ... >
<script ... >
</body>
回答3:
Make sure you have a closing tag on your root element.
I just spent the last 6 hours systematically removing things and pulling my hair out. Turns out I had deleted my closing at some point and Vue was interpreting
回答4:
a pair of mismatch tags (div, span) can cause this error.
<div id="app">
<div>{{ a }} </span>
</div>
回答5:
It is because of script tag in your app scope. In my case it was because of google captcha that was in my scope. Google captcha iframe contains script tag
