blocks|key|1397677|text|这很简单。在javascript中，任何有ID的东西都不需要document.queryselector或$('#test')，只需使用测试即可。然后，您只需循环遍历selectedOptions，它是javascript的一部分，您可以将其添加到一个新数组中，并随心所欲地使用该数据。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1397678|let+selectedItems+=+[];
for+(+var+i+=+0;+i+<+test.selectedOptions.length;+i%2B%2B)+{
++++selectedItems.push(test.selectedOptions[i].text);
}|code-block|syntax|javascript|1397679|也是|1397680|//+if+you+want+values
selectedItems.push(test.selectedOptions[i].value);|1397681|entityMap^0|U|M|1H|A|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|W|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|P|$]]

<p>It is pretty simple.  In javascript anything with an ID doesn't need <code>document.queryselector</code> or <code>$('#test')</code> you can just use test.  Then you simply loop over the selectedOptions which is apart of javascript and you can add it to a new array and use that data how ever you want.</p>
<pre><code>let selectedItems = [];
for ( var i = 0; i &lt; test.selectedOptions.length; i++) {
    selectedItems.push(test.selectedOptions[i].text);
}
</code></pre>
<p>Also</p>
<pre><code>// if you want values
selectedItems.push(test.selectedOptions[i].value);
</code></pre>


<p>In the following: </p>

<pre><code>&lt;select id="test"&gt;
    &lt;option value="1"&gt;Test One&lt;/option&gt;
    &lt;option value="2"&gt;Test Two&lt;/option&gt;
&lt;/select&gt;
</code></pre>

<p>How can I get the text of the selected option (i.e. "Test One" or "Test Two") using JavaScript</p>

<p><code>document.getElementsById('test').selectedValue</code> returns 1 or 2, what property returns the text of the selected option?</p>


Retrieving the text of the selected <option> in <select> element
