我需要在显示屏上显示cognos报告，并且报告需要在给定的时间间隔内刷新。
1）一份关于cognos报告的内容有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来显示多个认知报告，但是显示停止是我无法显示认知报告的所有页面，因为它只显示报告的第一页。
脚本显示多个认知报告。

任何人都可以帮我解决问题。

答案 0 :(得分：0)
这是通过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);
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iFrame中的报告推进一页。
挑战来自于遍历页面。您必须知道每个报告以某种方式有多少页面。如果报告有固定的，已知的页数则没问题。我创建了一个对象数组来存储源和页面数：
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，您可以遍历报表数组，像以前一样更改源，然后使用当前实例的currentpage和pagecount来确定推进页面的次数。你调用iframe.navigate（cognos.Report.Action.NEXT）;正确的次数并在报表对象上调用advanceCount（）来增加页面计数器。
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
