Java Wicket:如果选中复选框,则选中另一个复选框
Java Wicket: check another checkbox if checkbox checked
我有两个这样的复选框:
CheckBox checkBox1 = new CheckBox("enableCheckBox1", new PropertyModel<Boolean>(channelModel, "checkBox1"));
CheckBox checkBox2 = new AjaxCheckBox("enableCheckbox2", new PropertyModel<Boolean>(channelModel, "checkBox2")) {
@Override
protected void onUpdate(AjaxRequestTarget target) {
// check both checkBox1 and checkBox2
}
};
所以基本上,当我选中 checkBox2 时,我希望 checkBox1 也被自动选中。我该怎么做?
您必须更改 checkBox1 的模型对象并更新它:
CheckBox checkBox2 = new AjaxCheckBox("enableCheckbox2", new PropertyModel<Boolean>(channelModel, "checkBox2")) {
@Override
protected void onUpdate(AjaxRequestTarget target) {
if (getModelObject()) {
checkBox1.setModelObject(true);
target.add(checkBox1);
}
}
};
