selectonemenu

问题 I want to get selected object from <h:selectOneMenu> , but the problem is I couldn't find any generic converter for all type of entities. My first question is, is there a generic converter for all type of entities? I don't want to write another converter again for each other entity. My second question is, is there a way to get selected object without any converter? I don't want to call the DB again and again. I have a Car entity with id and name properties. 回答1: My first question is, is there

问题 I know how to preselect <p:selectOneMenu> , in selected value should be one of the objects from <f:selectItems> , but how does this component work under the hood and can I change this behavior? In my case I've a duplicate object, actually this is two objects with the same values but created twice and selected object in <p:selectOneMenu> differs from object from <f:selectItems> and it doens't recognize it.

问题 Is it possible to show images in <option> elements rendered by <h:selectOneMenu> tag of JSF? I use <f:selectItems> to generate the options that I get from the database. But the content I want to show in <h:selectOneMenu> is the image associated with each item. How can I achieve that? 回答1: It is impossible to embed images within JSF's <h:selectOneMenu> / <f:selectItem> / <f:selectItems> , as there are no attributes designed for that purpose. Moreover, there is hardly a cross-browser compatible

How can I get the focus on the select one menu when I tab into it? 回答1: You need to use the tabindex property of <p:inputText> and <p:selectOneMenu> , as explained in the documentation. 回答2: Using the tabindex property makes it

问题 Is it possible to set a <a href /> around my <f:selectItem itemLabel="label" /> where my link text is the itemLabel ? I'm using the plain sun components. 回答1: The desired result is not possible in HTML.
