如何在硒python中查找元素

Question

I have been using selenium for a little bit now and have been stuck on this issue for the past few hours. It seems really simple but I just can't seem to figure out a proper execution. I basically am trying to select a shoe size based on the user's input. Here are a few of the buttons I am trying to sort through as well as the surrounding HTML.

<p class="checkbox-size">
    <input type="radio" value="500" id="super_attribute[150]_500" name="super_attribute[150]" class="product_attribute">
    <label for="super_attribute[150]_500">
        <span id="label_eu0" class="label_hidden"> 38.5</span>
        <span id="label_us0" class="label_show"> 6</span>
        <span id="label_uk0" class="label_hidden"> 5.5</span>
        <span id="label_cm0" class="label_hidden"> 24</span>
    </label>
</p>

The specific button I am trying to press is this one:

<label for="super_attribute[150]_137">
    <span id="label_eu10" class="label_hidden"> 45</span>
    <span id="label_us10" class="label_show"> 11</span>
    <span id="label_uk10" class="label_hidden"> 10</span>
    <span id="label_cm10" class="label_hidden"> 29</span>
</label>

Now I tried many different methods of searching then clicking one of the buttons but nothing has worked yet. Any suggestions? Here is what I am currently using to try and find and click the button:

driver.find_element_by_css_selector("input[type='radio'][value='11']").click()

Looking back I might have not provided the correct code for the buttons, so here is a snapshot of the inspect element as well as the actual page if you want to go check it out for yourself. I am trying to click the size buttons. Button inspect element

Solved! Here is the code I ended up using.

sizes = driver.find_elements_by_class_name('checkbox-size')
for size in sizes:
    if size.text in [usersize]:
        size.click()
        print colored('Carted size %s'%(size.text), 'green')
        break
    continue

There are a few problems with your approach.

1. You are trying to click the INPUT when you need to click a SPAN

2. The sizes on the page contain some amount of whitespace which makes your strict string comparison, value='11', not work. Also the contained text is not considered a value .

3. Another issue you will run into is that all of the sizes aren't displayed. The sizes displayed is controlled by the links above the sizes, EU, US, UK, and CM. The ones that are displayed have class="label_show" so you will want to specify that in your answer or you will attempt to click elements that are not visible which will throw an exception. (Selenium only interacts with visible elements by design).

With all this, we can build the following XPath

//span[@class='label_show'][normalize-space(.)='10']

If it were me, I would throw this in a function that pass in the desired size as a string and insert that parameter into the above XPath to make this much more reusable.

试试下面的定位器（xpath）：

.//span[contains(@id,'label_eu') and text()=' 40']

Answer 3

Ok so here is what I ended up using which solved the issue. I made a list of all the web elements with the class 'checkbox-size' then traversed that list to to find the correct size, and then click on that element. Here is the code:

    sizes = driver.find_elements_by_class_name('checkbox-size')
for size in sizes:
    if size.text in [usersize]:
        size.click()
        print colored('Carted size %s'%(size.text), 'green')
        break
    continue
