我已经构建了一个检票口组件,其中包含输入/标签和更改表示的方法(必需、启用等)。组件渲染得很好,但是当表单提交时,我只看到 1 个表单参数“input”,它是最后一个 InputRow 组件。
输入行.html
<html xmlns:wicket="http://wicket.apache.org">
<head>
<link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>
<wicket:panel>
<label wicket:id="label">abc: <span class="req">*</span></label>
<span class="input">
<input wicket:id="input" type="text" id="name"></input>
</span>
<span wicket:id="input_feedback"></span>
</wicket:panel>
</body>
</html>
输入行.java
package com.wicket;
import org.apache.wicket.behavior.AttributeAppender;
import org.apache.wicket.feedback.FeedbackMessage;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.form.TextField;
import org.apache.wicket.markup.html.panel.Panel;
import org.apache.wicket.model.Model;
public class InputRow extends Panel{
@SuppressWarnings("unused")
private String id;
public InputRow(String id, String label) {
super(id);
this.id = id;
Label memberIdLabel = new Label("label",label);
memberIdLabel.setEscapeModelStrings(false)
.add(new AttributeAppender("for", new Model<String>(id),""));
add(memberIdLabel);
TextField<String> name = new TextField<String>("input");
name.setType(String.class)
.setMarkupId(id)
.setOutputMarkupId(true);
add(name);
add(new Label("input_feedback",""));
}
public InputRow disable()
{
get("input")
.setEnabled(false)
.add(new AttributeAppender("class", new Model<String>("disabled"),""));
get("label")
.add(new AttributeAppender("class", new Model<String>("disabled"),""));
return this;
}
public InputRow required()
{
Model model = (Model)get("label").getInnermostModel();
StringBuffer label = new StringBuffer((String)model.getObject());
label.append(" <span class=\"req\">*</span>");
model.setObject(label);
((TextField)get("input")).setRequired(true);
return this;
}
@Override
protected void onBeforeRender() {
super.onBeforeRender();
Label feedback = (Label)get("input_feedback");
if (get("input").getFeedbackMessage() != null)
{
feedback.setDefaultModel(new Model<String>("Required"));
}
}
}
添加到表单组件
add(new InputRow("name","Name:").required());
编辑 我没有设置 ListView 或中继器,因为我知道在构建时要添加到表单中的行/字段。
