Question

首先，我没有制作此代码，我不是java程序员，我只是将其从“反馈表单”页面修改为“请求表单”页面。我的目标是禁用提交按钮并提醒用户，如果未选中该复选框，则需要勾选复选框和/或阻止其提交数据。我想尽可能避免使用javascript。

以下是代码片段：

    public Serializable getKey() {

    String email = parameters.getParameter("email", "");
    String message = parameters.getParameter("message", "");
    String page = parameters.getParameter("page", "unknown");

    return HashUtil.hash(email + "-" + message + "-" + page);
}

/**
 * Generate the cache validity object.
 */
public SourceValidity getValidity() {
    return NOPValidity.SHARED_INSTANCE;
}

public void addPageMeta(PageMeta pageMeta) throws SAXException,
        WingException, SQLException, IOException,
        AuthorizeException {
    pageMeta.addMetadata("title").addContent(T_title);
    pageMeta.addTrailLink(contextPath + "/", T_dspace_home);
    pageMeta.addTrail().addContent(T_trail);
}

public void addBody(Body body) throws SAXException, WingException,
        UIException, SQLException, IOException, AuthorizeException {
    // Build the item viewer division.
    Division ill = body.addInteractiveDivision("ill-form",
            contextPath + "/ill", Division.METHOD_POST, "primary");
    ill.setHead(T_head);
    ill.addPara(T_para1);
    List form = ill.addList("form", List.TYPE_FORM);
    Text email = form.addItem().addText("email");
    email.setAutofocus("autofocus");
    email.setLabel(T_email);
    email.setHelp(T_email_help);
    email.setValue(parameters.getParameter("email", ""));
    TextArea message = form.addItem().addTextArea("message");
    message.setLabel(T_message);
    message.setValue(parameters.getParameter("message", ""));
    CheckBox copyright = form.addItem().addCheckBox("accept");
    String selected = !parameters.getParameter("accept", "true").equalsIgnoreCase("false") ? "true" : "false";
    copyright.setOptionSelected(selected);
    copyright.addOption("accept", T_copyright_agree);
    copyright.setLabel(T_copyright_label);
    copyright.setHelp(T_copyright);
    form.addItem().addButton("submit").setValue(T_submit);
    ill.addHidden("page").setValue(parameters.getParameter("page", "unknown"));
}
}

提前感谢您的帮助。

您可以将已定义复选框的HTML更改为： -

onClick="EnableSubmit(this)"

类似的东西： -

<input type="checkbox" name="ABC" value="XYZ" onClick="EnableSubmit(this)">

如果未选中复选框，如何禁用提交按钮？
