用于 Cognos 的 Javascript 在 iframe 中显示报告的所有页面

Question

我需要在显示屏上显示一个 cognos 报告，并且报告需要在给定的时间间隔内刷新。

1) 一份 cognos 报告中有 6 页，我需要一个接一个地显示所有六个页面，它应该转到下一个报告，并且必须以同样的方式显示所有页面在所有报告中。

目前我正在使用 iframe 显示多个 cognos 报告，但显示停止是我无法显示 cognos 报告的所有页面，因为它只显示报告的第一页。

显示多个 cognos 报告的脚本。

谁能帮我解决一下。

Answer 1

这是您通过 JavaScript 和 Cognos JS API 前进到下一页的方式：

var report = cognos.Report.getReport('_THIS_');
report.sendRequest(cognos.Report.Action.NEXT);

该 API 在 Cognos BI 10.2 及更高版本中提供。

我会在每个目标报告中创建一个函数，如下所示：

function navigate(action) {
    var report = cognos.Report.getReport('_THIS_');
    report.sendRequest(action);
}

然后我会从主代码中调用该函数：

var iframe = document.getElementById('slide');
iframe.navigate(cognos.Report.Action.NEXT);

这会将当前在 iFrame 中的报告前移一页。

挑战来自于循环浏览页面。您必须以某种方式知道每个报告有多少页。如果报告具有固定的已知页数，则没有问题。我会创建一个对象数组来存储源和页数：

var reports = [];
reports.push(new Report('http://COGDEVWEB1:80/ibmcognos/cgi-bin/cognosisapi.dll?b_action=cognosViewer&ui.action=run&ui.object=CAMID(%22dcanalyze%3au%3aa202da3d8b73bb4b954d583834a025a5%22)%2ffolder%5b%40name%3d%27My%20Folders%27%5d%2ffolder%5b%40name%3d%27Anil%27%5d%2ffolder%5b%40name%3d%27On%20Screen%20Testing%27%5d%2ffolder%5b%40name%3d%27BRACKENFELL%20SCHEDULES%27%5d%2ffolder%5b%40name%3d%27ON%20SCREEN%20DISPLAYS%27%5d%2ffolder%5b%40name%3d%27SCOREBOARD%20SCHEDULES%2007%3a00%20-%2019%3a00%27%5d%2freport%5b%40name%3d%27BRACKENFELL%20DC%20-%201ST%20PAGE%27%5d&ui.name=BRACKENFELL%20DC%20-%201ST%20PAGE&run.outputFormat=&run.prompt=true',4));
reports.push(new Report('http://COGDEVWEB1:80/ibmcognos/cgi-bin/cognosisapi.dll?b_action=cognosViewer&ui.action=run&ui.object=CAMID(%22dcanalyze%3au%3aa202da3d8b73bb4b954d583834a025a5%22)%2ffolder%5b%40name%3d%27My%20Folders%27%5d%2ffolder%5b%40name%3d%27Anil%27%5d%2ffolder%5b%40name%3d%27On%20Screen%20Testing%27%5d%2ffolder%5b%40name%3d%27BRACKENFELL%20SCHEDULES%27%5d%2ffolder%5b%40name%3d%27ON%20SCREEN%20DISPLAYS%27%5d%2ffolder%5b%40name%3d%27SCOREBOARD%20SCHEDULES%2007%3a00%20-%2019%3a00%27%5d%2freport%5b%40name%3d%27BRACKENFELL%20DC%20-%20FULL%20CASE%20PICKER%20SHIFT%201%27%5d&ui.name=BRACKENFELL%20DC%20-%20FULL%20CASE%20PICKER%20SHIFT%201&run.outputFormat=HTML&run.prompt=true',9));
...

function Report (src,pagecount) {
    this.src = src;
    this.pagecount = pagecount;
    this.currentpage = 1;
    this.advanceCount = function () {
        if (this.currentpage == this.pagecount) {
            this.currentpage = 1;
        } else {
            this.currentpage++;
        }
    }
}

然后，您可以遍历报告数组，像以前一样更改源，然后使用当前实例的 currentpage 和 pagecount 来确定前进页面的次数。您调用 iframe.navigate(cognos.Report.Action.NEXT);正确的次数并在报表对象上调用 advanceCount() 以增加页面计数器。

作为参考，您可以传递给 navigate() 函数的所有操作如下：

cognos.Report.Action.NEXT
cognos.Report.Action.BACK
cognos.Report.Action.REPROMPT
cognos.Report.Action.CANCEL
cognos.Report.Action.FINISH
