单击带有HtmlUnit的javascript按钮

Question

I'm trying to click a Html button using HTMLUnit. Button code:

<input class="Submit" value="I Accept." type="submit" name="ButtonSubmit" id="button" onclick="/*some looong js code*/" tabindex="16">

My code

final HtmlSubmitInput baton = form.getInputByName("ButtonSubmit");
HtmlPage page2 = baton.click();

I tried using click(); method but it does not work.

also pressing enter key:

final HtmlTextInput textinput = form.getInputByName("SomeInput");
//filling input
HtmlPage page = textinput.type(KeyboardEvent.DOM_VK_ENTER);

I think problem is with the js code. It just does't run using HTMLUnit. (Filling the form manually, with browers, works fine.) Thanks for help.

Answer 1

make sure to enable JS in your code

webClient.getOptions().setJavaScriptEnabled(true); webClient.getOptions().setThrowExceptionOnScriptError(false);

Answer 2

I don't know if this will solve your problem, but there are two things I do differently to get around this (Javascript doesn't seem to click on elements):

• Use form.getElementById("button") instead of getInputByName
• Use Thread.sleep to wait (around 350 ms seems to be the magic number) for the effect to take place

Even with this, I still see non-determinstic test failures because the effects of the click sometimes just don't seem to happen.
