+
+<ul>
+ <li>selection은 {{domxref("Selection")}} 객체입니다. 빈 문자열("")을 추가하거나 {{domxref("Selection.toString()")}}을 호출하면 선택된 text를 반환합니다.</li>

+<pre class="brush:js">function foo() {
+    var selObj = window.getSelection();
+    alert(selObj);
+    var selRange = selObj.getRangeAt(0);
+    // do stuff with the range

+<h3 id="Selection_객체의_문자열_표현">Selection 객체의 문자열 표현</h3>
+
+<p>JavaScript에서 문자열을 인자로 받는 함수({{ Domxref("window.alert()") }} 나 {{ Domxref("document.write()") }} 같은)에 객체를 전달하면 해당 객체의 {{jsxref("Object.toString", "toString()")}} 메소드를 호출하고 그 결과를 호출한 함수로 전달합니다. 이를 통해서 실제로는 속성과 메소드를 갖는 문자열이 아닌 일반적인 객체라 하더라도 문자열을 인자로 받는 함수의 인자로 사용할 때에는 객체를 문자열인 것처럼 전달할 수 있습니다.</p>
+
+<p>위 예제에서 selObj를 {{domxref("window.alert()")}}의 인자로 전달하면 <code>selObj.toString()</code>가 자동적으로 호출됩니다. 하지만, selObj에 대해서 <code><a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/length" title="JS/String.length">length</a></code> 나 <code><a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/substr" title="JS/String.substr">substr</a></code> 같은 JavaScript <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/String" title="JS/String">String</a>의 속성이나 메소드를 사용하면 객체에 그러한 속성이나 메소드가 없기 때문에 에러나 예상치 못한 결과가 발생합니다. <code>Selection</code> 객체를 문자열로 사용하려면 다음처럼 직접 <code style="font-style: normal;">toString()</code> 메소드를 호출해야 합니다:</p>
+
+<pre class="brush:js;gutter:false;">var selectedText = selObj.toString();</pre>
+
+<ul>
+ <li><code>selObj</code>는 <code>Selection</code> 객체입니다.</li>
+ <li><code>selectedText</code>는 문자열 (선택한 문자열)입니다.</li>
+</ul>
+
+<h3 id="Related_objects">Related objects</h3>
+
+<p>It's also useful to note that you can call {{domxref("Document.getSelection()")}}, which works identically.</p>
+
+<p>HTML inputs provide simpler helper APIs for working with selection (see {{domxref("HTMLInputElement.setSelectionRange()")}}).</p>
+
+<p>Notice the difference between <em>selection</em> and <em>focus</em>. {{domxref("Document.activeElement")}} returns the focused element.</p>
