| let selection = document.getSelection(); | ||
| let selRange = selection.getRangeAt(0); | ||
| // do stuff with the range | ||
|

| </pre> | ||

|

| <h3 id="String_representation_of_the_Selection_object">String representation of the Selection object</h3> | ||
|
|
||
| <p>Some functions (like {{DOMxRef("Window.alert()")}}) call {{JSxRef("Object.toString", "toString()")}} | ||
| automatically and the returned value is passed to the function. As a consequence, this will return the selected text | ||
| and not the <code>Selection</code> object:</p> | ||
|
|
||
| <pre class="brush:js;">alert(selection);</pre> | ||
|
|
||
| <p>However, not all functions call <code>toString()</code> automatically. | ||
| To use a <code>Selection</code> object as a string, call its <code>toString()</code> method directly:</p> | ||
|
|
||
| <pre class="brush:js;">let selectedText = selection.toString();</pre> | ||
|
|
||
| <h2 id="Related_objects">Related objects</h3> | ||
|
|
||
| <p>You can call {{domxref("Window.getSelection()")}}, which works identically to | ||
| <code>Document.getSelection()</code>.</p> | ||
|
|
||
| <p>It is worth noting that currently <code>getSelection()</code> doesn't work on the | ||
| content of {{htmlelement("input")}} elements in Firefox. | ||
| {{domxref("HTMLInputElement.setSelectionRange()")}}) could be used to work around this. | ||
| </p> | ||
|
|
||
| <p>Notice also the difference between <em>selection</em> and <em>focus</em>. | ||
| {{domxref("Document.activeElement")}} returns the focused element.</p> | ||
