如何在数学羽毛笔中输入\\ sqrt [3] {64} = 4

Question

If you paste that code \\sqrt[3]{64}=4 its working good.

But at the time of writing the input \\sqrt[3]{64}=4 , the root is not renderd as expected. How can I get the result like in the picture above at the time of typing?

This is my code:

  var mathFieldSpan = document.getElementById('math-field'); var MQ = MathQuill.getInterface(2); // for backcompat var mathField = MQ.MathField(mathFieldSpan, { spaceBehavesLikeTab: true, // configurable }); 

 #math-field{ position:absolute; width:65%; left:40px; height:40px; border-radius:5px; box-shadow:none; outline:none; font-family:Lato,sans-serif;color:#767676;font-weight:400; border:2px solid #20BF9F; font-size:15px; transition:all 0.5s ease-out; } 

 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <link rel="stylesheet" type="text/css" href="http://mathquill.com/lib/mathquill.css"> <script type="text/javascript" src="http://mathquill.com/lib/mathquill.js"></script> <span id="math-field" ></span>

You can achieve this when typing: \\nthroot3{64}=4 .
Note that the latex of the mathfield is converted to: \\sqrt[3]{64}=4 .
