How to click an <option> element with WebDriver?
提问by Kiran Koundinya
This is a piece of UI code
这是一段UI代码
<select id="order_unit_line_rate_806782_is_addenda_enabled" class="selects_for_487886" onchange="select_addendum(806782, this);dateShowMemory(this.options[this.selectedIndex].value, '806782');" uniqueattr="Dynamic Site Accelerator / Dynamic Site Accelerator / Additional Usage Commitment / drop down" name="order_unit_line_rate[806782][is_addenda_enabled]">
<option value="0" uniqueattr="Dynamic Site Accelerator / Dynamic Site Accelerator / Additional Usage Commitment / Fee"> Fee </option>
<option value="1" uniqueattr="Dynamic Site Accelerator / Dynamic Site Accelerator / Additional Usage Commitment / See Attached Addendum"> See Attached Addendum </option>
</select>
where the <option>tags are nested inside the <select>tag. I need to click()on the second <option>element which is an item in the dropdown list. The dropdown is clickable when i try to click()on the <select>tag using id / uniqueattr.
其中<option>标签嵌套在<select>标签内。我需要click()在第二个<option>元素上，它是下拉列表中的一个项目。当我尝试使用 id / uniqueattrclick()在<select>标签上时，下拉菜单是可点击的。
How do I traverse the <option>tags nested under <select>and click on the right item?
如何遍历<option>嵌套在下面的标签<select>并单击正确的项目？
采纳答案by Qwerky
This will select the option with value "1" in the select with id "order_unit_line_rate_806782_is_addenda_enabled".
这将在 ID 为“order_unit_line_rate_806782_is_addenda_enabled”的选择中选择值为“1”的选项。
Select select = (Select)webdriver.findElement(By.id("your id here"));
select.selectByValue("1");
You can also select by index or text; see the docs.
也可以按索引或文本选择；请参阅文档。

Besides the correct Qwerky's answer, you can also do simple
除了正确的 Qwerky 的答案，你还可以做简单的
driver.findElement(By.xpath("//select/option[@value='1']")).click();
This finds the optionelement with value='1'and clicks it, practically selecting it in the drop-down.
这会找到option元素value='1'并单击它，实际上是在下拉列表中选择它。
Both mine and Qwerky's solution are described and explained here, in the documentation.
