将JSF（primefaces）托管bean变量传递给javascript函数

Question

I have a JSF/primefaces managed bean.I am trying to pass managed bean variable to JavaScript function within the same managed bean but i am not successful. Can someone please help me in achieving this task.

My managed bean code snippet

reportName=report[0];
    url="http://cvgapp42q/Reports/Pages/Report.aspx?ItemPath=%2fLPSR%2f"+reportName;
    try {

        RequestContext.getCurrentInstance().execute("window.open('#{repBean.url}')");
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

url is the variable which i am trying to refer using the expression #{repBean.url} in the javascript function window.open()

Thanks in advance

Answer 1

just put your javascript code in a panel on your page:

<h:panelGroup id="scriptPanel">
    <script>
        window.open('#{repBean.url}');
    </script>
</h:panelGroup>

and update this panel after your ajax request, using update="scriptPanel" on your related primefaces component.

Answer 2

Use

@ManagedProperty(value="#{repBean}")
RepBean repBean

and in your method

try {
    RequestContext.getCurrentInstance().execute("window.open('"+repBean.getUrl()+"')");
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
