Answer 1

使用Number#toFixed或使用字符串而不是数字。

var minValue = 0.00000001;

var message =  "Min value is " +  minValue.toFixed(8);

var content = $('p#content').text(message);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p id="content"></p>

Answer 2

var minValue = "0.00000001";

var message =  "Min value is " +  minValue;

var content = $('p#content').text(message);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p id="content"></p>
