How to click hidden button use selenium2library

[Lane]

I manually can click this button, but use selenium2library will get element not found.

There are any way to click this button?

html:

<span id="Wireless_enable0" class="bt_radio" style="background-position: 0px -18px;"></span>

<input type="radio" id="Wireless_enable" name="Wireless_enable" value="1" lang="1" checked="" style="visibility: hidden;">

<label for="yes">Yes</label>

If you can see the button Selenium should see it too. Do you run test on your machine or on some remote server? If latter, then try to check if the button is actually visible in browser (I once ran into problems due to low screen resolution on test server - some buttons were not visible in small browser window). Maybe this will help you.

You could use Selenium2Library keyword for executing javascript. Then execute javascript that changes the DOM element from visibility hidden to not (whatever the appropriate value is), then you should be able to click the element.

But that's a last resort option if you really must click it (and the button happens to be set invisible). Or maybe you're not clicking the actual element, it may be another one that's adjacent that is "visible" that you're supposed to click, not the hidden one, as it's hidden for a reason.

Hi David,

I don't know how to use execute javascript to changes the DOM element from visibility hiddent to visible.

Have example according to my html code?

Is this really true or are you getting an ElementNotVisibleException?

Like David was saying, manipulating the AUT should be a last resort.

When you inspect the element that you click on using Firebug, etc., which element is actually highlighted, the span? That is the element you should be trying to click on. It looks like your AUT might have an event listener on another element and toggles the value of the input element when the other element gets an onClick event.

There are times where I had to use Simulate instead of a Click keyword.

XPath seems correct to find element in the HTML fragment from your earlier post. Either the element is not there when this is run or it is in a frame/iframe.

Have you tried using the Wait Until keywords?

[Lane]

You are right!!  I have no select to correct frame.

Now, I select frame will get error.

As a user, you cannot interact with hidden elements. WebDriver refuses to do so because it is trying to be a realistic test tool.

Whatever you have to do to get the element to become visible as a human with a mouse, you will have to do the same in the automation. Sometimes the automation is to fast, so the Wait Until Element Is Visible keyword may help there.

I can use mouse to click this checkbox, but still show hidden in html code.

I have use sleep to make sure page is displayed when run robot.

This html code is our design by our produce. Is not this html code is design wrong? I can tell our engineers to modify this code, but if automation can do, this code will not need to be modify.

Ugh

Have you used Firebug [1], or similar tool, to verify the number of matching elements? Because Selenium2library is designed to take the first matching element from the DOM tree and interact with that element.

Because if you say that you can see and click the elements but the element is hidden from the html code,  then you are looking/referring to the wrong element or something very weird is going on. In any case consulting your developer is a good idea. Because sometimes the DOM tree can be quite messy to read and understand.
