Question

我的问题类似于issue 我有一个在XHTML中，它调用支持bean方法来调用一个带有预构建URL的新窗口。但我的问题是它没有打开URL。

我在XHTML中的代码在下面给出了

 <h:commandButton  style="margin-left:1em;width: auto; height: 20px;font-size:85%"
value="WebPhone" id="lwebpne"rendered="#{Bean.editCmdActionflg == true and (Bean.selectedSearchSysDetRow.isfeed != '1'  or Bean.selectedOverviewDetails.webPheFlg == false)}"actionListener="#{Bean.webPhoneSearch}"   >
<f:param name="lpid" value="lpid" />
</h:commandButton>

我的代码在支持bean中给出了

public void webPhoneSearch(ActionEvent event) {
        logger.info("webPhoneSearch Method Enter ..");

        String param = "";

        Map<String, String> params = FacesContext.getCurrentInstance()
                .getExternalContext().getRequestParameterMap();

    if (params.get("lpid") != null) {
            System.out.println("coming inside>>>>>");
            // String t_lpid = params.get("lpid");
            String t_lpid = selectedOverviewDetails.getLeadPrgMgrUid();
            Matcher matcher = pattern.matcher(t_lpid);
            if (matcher.matches()) {
                param = "this values comes from UI ";
            }
        }
// below is a  URL where the window will launch to show the details of a person which we are search for
    Url = "http:// URL for searching a person in webphone" +param;
        RequestContext.getCurrentInstance().execute(
                "window.open('" + Url + "')");

        logger.info("webPhoneSearch Method Exit ..");

}<br/>

我的问题是，当我点击<h:commandbutton>时，<h:commandbutton>没有打开新窗口，而是在当前窗口中重新打开同一页面
请让我知道您解决此问题的建议。

正如@Alexandre所说，＆lt; h：commandButton /＆gt;没有taget属性。使用＆lt; h：commandLink /＆gt;

<h:commandLink target="_blank"
                 style="margin-left:1em;width: auto; height: 20px;font-size:85%"
                 value="WebPhone" id="lwebpne"
                 rendered="#{Bean.editCmdActionflg == true and (Bean.selectedSearchSysDetRow.isfeed != '1'  or Bean.selectedOverviewDetails.webPheFlg == false)}"
                 actionListener="#{Bean.webPhoneSearch}">
    <f:param name="lpid" value="lpid"/>
</h:commandLink>

---更新：---

如果您想触发某些javascript事件，可以使用＆lt; f：ajax /＆gt;。我的样本如下。

<h:commandButton style="margin-left:1em;width: auto; height: 20px;font-size:85%"
                 value="WebPhone" id="lwebpne" rendered="#{Bean.editCmdActionflg == true and (Bean.selectedSearchSysDetRow.isfeed != '1'  or Bean.selectedOverviewDetails.webPheFlg == false)}">
    <f:ajax execute="@form" render="@form" listener="#{Bean.webPhoneSearch()}" onevent="eventListener"/>
</h:commandButton>
<h:outputScript>
    function eventListener(data) {
        if (data.status == "complete") {
            <!-- YOUR WINDOW ADDRESS HERE -->
            window.open('http://google.com', '_blank');
        }
    }
</h:outputScript>

但我不建议使用弹出窗口。因为所有浏览器都会阻止它们。我认为dialog framework或lightbox组件可能更有用。

JSF- <h：commandbutton>不会从支持bean </h：commandbutton>调用新窗口
