尝试在名为TimeEdit的页面上使用HTMLUnit，该页面主要用于为学校制定计划。我想在输入字段中添加一个搜索词（＆＃34; DV1431＆＃34;）： TimeEdit
然后我想以某种方式提交。我已经读过你可以使用HTMLUnit触发JavaScript，并且你可以使用按钮甚至创建＆＃34;假的＆＃34;。但我不确定在我的情况下最好的方法是什么。
我尝试过在Stackoverflow上找到的解决方案：Youtube-example 这个工作，但在我的页面TimeEdit上没有我可以使用的HTML表单。相反，只有一个名为searchButtons的类，其中提交按钮和输入字段位于其中。 这是我的示例代码：
WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setCssEnabled(false);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setUseInsecureSSL(true);
webClient.getCookieManager().setCookiesEnabled(true);
//Get the page
HtmlPage currentPage = webClient.getPage("https://se.timeedit.net/web/bth/db1/sched1/ri1Q7.html");
//Just for testing purpose
System.out.println(currentPage.getUrl());
// Get form where submit button is located
// But on this page there is no form, just a class called searchButtons
HtmlForm searchForm = (HtmlForm) currentPage.getElementById("ffsearchname");
// Get the input field.
HtmlTextInput searchInput = (HtmlTextInput) currentPage.getElementById("ffsearchname");
// Insert the search term.
searchInput.setText("DV1431");
// Workaround: create a 'fake' button and add it to the form.
HtmlButton submitButton = (HtmlButton) currentPage.createElement("button");
submitButton.setAttribute("type", "submit");
searchForm.appendChild(submitButton);
// Workaround: use the reference to the button to submit the form.
HtmlPage newPage = submitButton.click();
//Testing purpose
System.out.println(newPage.getUrl());
如果提交按钮和输入字段不在表单中，如何在输入字段中设置searchterm时如何提交？

不知道为什么要尝试插入按钮以及为什么您希望该按钮可能有用。 如果你想自动化一些Html页面，你需要对html的方式有一些基本的了解，在你的情况下也需要javascript工作。
// no need to set any options just use the default
WebClient webClient = new WebClient(BrowserVersion.CHROME);
// Get the page and wait for the javacode that will start with an minimal delay
// doing something like setTimeout(init(), 10); is a common trick done by some js libs
HtmlPage currentPage = webClient.getPage("https://se.timeedit.net/web/bth/db1/sched1/ri1Q7.html");
currentPage.getEnclosingWindow().getJobManager().waitForJobsStartingBefore(100);
// Get the input field.
HtmlTextInput searchInput = (HtmlTextInput) currentPage.getElementById("ffsearchname");
// Insert the search term.
searchInput.setText("DV1431");
// the output
DomElement output = currentPage.getElementById("objectsearchresult");
System.out.println("- before -------------------------------------------------------------------");
System.out.println(output.asText());
System.out.println("----------------------------------------------------------------------------");
// try to find the button
for (final DomElement elem : currentPage.getElementsByTagName("input")) {
if ("Sök".equals(((HtmlInput) elem).getValueAttribute())) {
// click and again wait for the javascript
currentPage = elem.click();
currentPage.getEnclosingWindow().getJobManager().waitForJobsStartingBefore(100);
System.out.println();
output = currentPage.getElementById("objectsearchresult");
System.out.println("- after --------------------------------------------------------------------");
System.out.println(output.asText());
System.out.println("----------------------------------------------------------------------------");
break;
}
}
