Watir webdriver_unable to click Cancel Target button on popup window

问题

I am VERY new to Watir, trying to test a popup window and am unable to get my script to click the Cancel Target button. When running the script, I get an error: element not visible (Selenium::WebDriver::Error::ElementNotVisibleError. This is the script I am using:

browser.div(:class => "modal-footer").button(:class => "btn btn-danger").click

Below is the code:

<div class="modal hide fade" id="target_modal" data-bind="with: target">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h3 data-bind="text: BusinessName"></h3>
    </div>

    <div class="modal-body">
        <div class="row">
            <div class="span3">
                <label for="FirstName">First Name</label><input id="FirstName" type="text" data-bind="value:FirstName" />
                <label for="LastName">Last Name</label><input id="LastName" type="text" data-bind="value: LastName" />
                <label for="Email">Email</label><input id="Email" type="text" data-bind="value: Email" />
            </div>
        </div>
    </div>

    <div class="modal-footer">
        <button class="btn btn-primary" data-bind="click: saveTarget">
            <i class="icon-white icon-ok"></i>
            Save Target
        </button>

        <button class="btn btn-danger" data-dismiss="modal">
            <i class="icon-white icon-remove"></i>
            Cancel Target
        </button>
    </div>
</div>

Any help would be greatly appreciated. Thanks!

回答1:

I assume that this popup is part of the page (ie just an div tag overlaying the rest of the page), rather than a new browser window popup.

My guess is that Watir is trying to click the button before the popup finishes being displayed. Explicitly telling Watir to wait for the button may solve the problem:

cancel_button = browser.div(:class => "modal-footer").button(:class => "btn btn-danger")
cancel_button.when_present.click

I got it to work. Justin Ko's 1st answer got me thinking and this worked:

cancel = browser.div(:id => "target_modal") 
cancel.div(:class => "modal-footer").button(:class => "btn btn-danger").i(:class => "icon-white icon-remove").click
