我有1个下拉列表,基于下拉值选项卡将启用或禁用。默认情况下,我对所有选项卡使用getTabContainerCssClass(),它会将所有选项卡显示为启用视图,但我想更改选项卡css类,因为它在更改下拉列值后看起来像是禁用。

关于这个的任何想法......
更新:更新代码后
DropDownChoice ProductDropDown = new DropDownChoice("ProductList", new PropertyModel(this, "SupplierProduct"),ProductList, new choiceRenderer("name","id"));
add(supplierProductDropDown);
supplierProductDropDown.add(new AjaxFormComponentUpdatingIndicatingBehavior("onchange"){
@Override
protected void onUpdate(AjaxRequestTarget target) {
/* do some code for changing dropdown */
}
});
tabs = new ArrayList<AbstractTab>();
/* provide some tab details */
tab = new AjaxTabbedPanel("tabs", tabs){
private static final long serialVersionUID = 1L;
@Override
protected String getTabContainerCssClass() {
return "producttab-row";
}
@Override
protected WebMarkupContainer newLink(String linkId, final int index) {
return new Link(linkId)
{
private static final long serialVersionUID = 1L;
public void onClick() {
setSelectedTab(index);
}
@Override
public boolean isEnabled() {
if(index == 1 && /*drop down condition that will be disable the tab*/){
/*I want to change css of this tab*/
return false;
}
else{
return true;
}
}
}
}
}
但它并没有对此有所帮助。请帮忙
解决方案:我在AjaxTabbedPanel.see中覆盖了onComponentTag,代码如下
@Override
protected void onComponentTag(final ComponentTag tag) {
// TODO Auto-generated method stub
super.onComponentTag(tag);
if(/*Dropdown condition*/){
tag.append("class", "disabletab", " ");
}
}
答案 0 :(得分:2)
您应该覆盖Link#onComponentTag(ComponentTag)
方法并将CSS类设置为:tag.append("class", "dynamicValueDependingOnDropDownsModel", " ")
。
