<h2 id="哪里出错了？">哪里出错了？</h2>
<p>某处 js 解析字符串出错。字符串必须使用单引号或双引号来正确的关闭。在 Javascript 中使用单引号的字符和双引号的字符串是没有区别的。字符串用<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String#Escape_notation">转义字符</a>不是单引号就是双引。为解决这个错误，检查一下：</p>
<ul>
<li>你字符串的引号是否成对。</li>
<li>你是否正确使用了转义序列</li>
<li>你的字符串是否在多行中解析正常。</li>
</ul>

<h3 id="多行字符串">多行字符串</h3>
<p>在javascript中你不能够直接使用多行字符串赋值给一个变量。如下：</p>
<pre class="brush: js example-bad">var longString = "This is a very long string which needs
to wrap across multiple lines because
otherwise my code is unreadable.";
// SyntaxError: unterminated string literal</pre>
<p>可以使用<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Addition">"+"运算符</a>，反斜杠，或<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals">模板字符串</a>来代替多行。“+”运算符的使用如下：</p>
<pre class="brush: js example-good">var longString = "This is a very long string which needs " +
"to wrap across multiple lines because " +
"otherwise my code is unreadable.";
</pre>
<p>或者你可以使用“\”在每一行的末尾，以表示该字符串在下一行继续。要确保“\“之后没有没有空格和任何其他的字符，及缩进，否则该“\”将不会起作用。使用方法如下：</p>
<pre class="brush: js example-good">var longString = "This is a very long string which needs \
to wrap across multiple lines because \
otherwise my code is unreadable.";
</pre>
<p>另一种方式是使用 ES 2015 的环境所支持<a class="new" href="Reference/Template_literals" rel="nofollow">模板字符串</a>（反引号` `）。</p>
<pre class="brush: js example-good">var longString = `This is a very long string which needs
to wrap across multiple lines because
otherwise my code is unreadable.`;</pre>
