How to choose value from an option list using PyQt4.QtWebKit

Question

I’m trying to auto-select a birthday from an option list on my website by using PyQt4.QtWebKit, but I’m having trouble doing this.

When I want to select a radio button I do this:

doc = webview.page().mainFrame().documentElement()
g = doc.findFirst("input[id=gender]")
g.setAttribute("checked", "true")

Or set some text input:

doc = webview.page().mainFrame().documentElement()
s = doc.findFirst("input[id=say_something]")
s.setAttribute("value", "Say Hello To My Little Friends")

But how do I select a month from this option list?

<select tabindex="11" name="birthday_m">
    <option value="">---</option>
    <option value="1">JAN</option>
    <option value="2">FEB</option>
    <option value="3">MAR</option>
</select>

I did it this way :

doc.evaluateJavaScript('document.getElementsByName("birthdate_m")[0].options[3].selected = true')

If you have any suggestions, on how to improve it, please let me knnow.

The QWebKit classes use CSS2 selector syntax to find elements.

So the required option could be found like this:

doc = webview.page().mainFrame().documentElement()
option = doc.findFirst('select[name="birthday_m"] > option[value="3"]')

and then the selected attribute can be set on the option element like this:

option.setAttribute('selected', 'true')

However, for some reason, this does not immediately update the page (and nor does calling webview.reload()).

So if you need an immediate update, a better way might be to get the select element:

doc = webview.page().mainFrame().documentElement()
select = doc.findFirst('select[name="birthday_m"]')

and then set the selected option like so:

select.evaluateJavaScript('this.selectedIndex = 3')
