具有可变刷新时间的 APEX 5.1 自动刷新区域 [英] APEX 5.1 autorefresh Region with variable refresh time

问题描述

• P998_SESS_INFO 是我的经典报告
• P998_REFRESH 是隐藏项
• P998_REFRESH_RATE 是具有 STATIC 静态值的 LOV:
  • 10 秒；10000，
  • 20 Sekunden;20000,
  • 30 秒；30000
  • P998_SESS_INFO is my classic report
  • P998_REFRESH is hidden item
  • P998_REFRESH_RATE is LOV with static values of STATIC:
    • 10 Sekunden;10000,
    • 20 Sekunden;20000,
    • 30 Sekunden;30000

    我为 P998_REFRESH 定义了一个 java 脚本表达式类型的动态操作:

    I define a dynamic action of type java script expression on change set value for P998_REFRESH:

    $x('P998_REFRESH').value = $x('P998_REFRESH_RATE').value;
    

    HTML 标题:

    <script type="text/javascript">
      var interval = `$`v("P998_REFRESH");
      // refresh every 10 seconds
      setInterval("jQuery('#P998_SESS_INFO').trigger('apexrefresh');", interval); 
    </script>
    

    但这行不通.有什么建议吗?谢谢

    but this will not work. Any suggestions available? Thank you

    推荐答案

    两个问题:

    1 - 此代码不会启动项目上的事件更改.(这会更改页面上的值，但不会触发动态操作).而不是这个

    1 - this code do not start the event change on item. (this change the value on the page, but not trigger the dynamic action). instead of this

    $x('P998_REFRESH').value = $x('P998_REFRESH_RATE').value;
    

    试试这个

    $s('P998_REFRESH', $x('P998_REFRESH_RATE').value);
    

    2 - 您需要清除之前的 setInterval 值.设置新的间隔还不够.所以你需要在每次调用 setInterval 时存储在一个变量中

    2 - you need to clear the previous setInterval value. it's not enough set new interval. So you need to store in a variable every call to setInterval

     var sintervalid = setInterval("jQuery('#P998_SESS_INFO').trigger('apexrefresh');", interval);
    

    并重置

    clearInterval(sintervalid);
    sintervalid = setInterval("jQuery('#P998_SESS_INFO').trigger('apexrefresh');", interval);
    

    <小时>

    如果我要做这样的事情，我会这样尝试:

    ---

    If I were to do something like this, I would try it like this:

    1 - 我在我的 html 标题中创建一个全局变量，设置默认值:

    1 - I create one global variable in my html header, setting the default value:

    <script type="text/javascript">
      var sIntervalId = setInterval(function(){ 
                          jQuery('#P998_SESS_INFO').trigger('apexrefresh');
                        }, 30000);
    </script>
    

    2 - 我在更改存储间隔的项目时创建一个动态操作

    2 - I create a dynamic action when change my item that store the interval

    动态动作:更改项目 P998_REFRESH_RATE

    dynamic action: change item P998_REFRESH_RATE

    真正的行动:执行javascript代码:

    true action: execute javascript code:

    clearInterval(sIntervalId);
    sIntervalId = setInterval(function(){ 
                              jQuery('#P998_SESS_INFO').trigger('apexrefresh');
                            }, $x('P998_REFRESH_RATE').value);
    

    ***我没有测试过这个，但或多或​​少会这样.

    ***I did not test this, but it would be more or less that way.
