硒选择无法找到选项

Question

I am having an issue when I locate and assign a Select object grabbing its options, probably due to some of the wonky HTML on the page. Here is the HTML of the Select and its options:

<select>
<option selected="" val="1">1</option>
<option val="2">2</option>
<option val="3">3</option>
<option val="4">4</option>
<option val="5">5</option>
...
</select>

The select is located using XPath as such: .//*[@id='employeeTable_paginate']/div/select

I am wondering if it isn't able to locate the options since the values are referred to as vals in the HTML? I tried the following code to see if it would get the Options:

for (WebElement option : select.getOptions()) System.out.println(option);

but it does not print anything. Additionally, if I try to select an option by index, it says it can not locate option with that index.

selectByValue would definitely not work in that case. If you go to the implementation of Select , you can see that selectByValue() uses xpath to find the value field. The good news is that it's an easy fix.

For your case, you'll want to find the single value (searching for val instead), and select it.

WebElement option = element.findElement(By.xpath(
        ".//option[@val = '" + value + "']"));

if (!option.isSelected())
{
    option.click();
}

I'm not sure why selectByIndex doesn't work, can you check the count of select.getOptions() ? It's always possible the select object is just incorrect.
