Change value field in html input tag using selenium in python

问题

The html tag.

<input id="input-value" title="Search" type="text" value="">

I want to change the value attribute from "" to "foo".

<input id="input-value" title="Search" type="text" value="foo">

I am trying this with send_keys to no success.

ele = browser.find_element_by_id("input-value")
ele.send_keys("foo")
ele.send_keys(Keys.RETURN)`   

回答1:

To edit the value attribute and assign the value foo to it you can use the following code block which uses the JavascriptExecutor :

ele = browser.find_element_by_css_selector("input#input-value")
browser.execute_script("arguments[0].setAttribute('value','foo')", ele)

回答2:

Using .click() before .send_keys() like:

ele = browser.find_element_by_id("input-value")
ele.click()
ele.send_keys("foo")
ele.send_keys(Keys.RETURN)
