<p>[Symbol.split]指向‘aba’.split(/a/)</p>

<pre class="brush: js notranslate">/a/[Symbol.split]('aba',3)</pre>

<p>"dayinlove".split(exp)调用[Symbol.split](str)处理，并把实参"dayinlove"传给形参str</p>

<pre class="brush: js notranslate">var exp =  {
        pat:'in',
        [Symbol.split](str) {
          return str.split(this.pat);
          }
    }

    "dayinlove".split(exp);
//["day", "love"]</pre>
