JSF 更改 css 样式属性 onclick

Question

需要明确的是，我有一个具有特定样式的 div，当我单击该 div 内的命令按钮时，我想将显示属性设置为“无”。

我希望通过单击命令按钮来更改 css 样式。

这是我的 xhtml ：

<div class="details" id="detailsPopUp" style="#{detailsPopUpManager.style}">
                <h:commandButton image="resources/images/close Icon.png" 
                                 action="#{detailsPopUpManager.closePopUp()}" 
                                 class="closeIcon"/>
</div>

这是 detailsPopUpManager 代码：

 @Named(value = "detailsPopUpManager")

 @SessionScoped

 public class DetailsPopUpManager implements Serializable {

    private String style;
    public DetailsPopUpManager() {
        style = "width:500px;\n" +
                "height:500px;\n" +
                "background: graytext;\n" +
                "position: absolute;\n" +
                "right: 25%;\n" +
                "top: 10px;\n" +
                "z-index: 1;";
    }

    public String getStyle() {
        return style;
    }

    public void setStyle(String style) {
        this.style = style;
    } 

    public void closePopUp()
    {
        style = "width:500px;\n" +
                "height:500px;\n" +
                "background: graytext;\n" +
                "position: absolute;\n" +
                "right: 25%;\n" +
                "top: 10px;\n" +
                "z-index: 1;\n" +
                "display: none;";
    }

感谢您的进一步帮助。

您需要使用 ajax 来实现该结果。

<h:form id="myForm">
   <div class="details" id="detailsPopUp" style="#{detailsPopUpManager.style}">
                <h:commandButton image="resources/images/close Icon.png" 
                                 action="#{detailsPopUpManager.closePopUp()}" 
                                 class="closeIcon">
                   <f:ajax render="myForm"/>
                </h:commandButton>

   </div>
</h:form>
