Deselecting all elements from a multi-select dropdown in jQuery
提问by Fero
I have a multi-select drop down as following, where I have selected the options "Test 2" and "Test 3".
我有一个多选下拉菜单,如下所示,其中我选择了“测试 2”和“测试 3”选项。
<select id="edit-rec" class="form-select" multiple="multiple" name="rec[]">
<option value="6012">Test 1</option>
<option value="8436">Test 2</option>
<option value="4689">Test 3</option>
<option value="6784">Test 4</option>
</select>
I have a button called "Deselect All". When this button is clicked, all selected items should be deselected. In this case, the items I previously selected, "Test 2" and "Test 3", should now become deselected.
我有一个名为“取消全选”的按钮。单击此按钮时,应取消选择所有选定的项目。在这种情况下,我之前选择的项目“测试 2”和“测试 3”现在应该取消选择。
How can I accomplish this using jQuery?

The easiest way that I found to unselect all options in a multi-select dropdown was using .val([])
.
我发现在多选下拉列表中取消选择所有选项的最简单方法是使用.val([])
