Hi,
I have a HTML external to BIRT deployment which has following:
<table id="graphid">
<tr>
<td>
<b>Choose Parameters:</b>
</td>
<!--<td>
<input type="hidden" name="__report" value="DynamicRpt.rptdesign" />
</td> -->
<td>
<SELECT NAME="choiceX" id="choiceX">
<OPTION VALUE="Country">Country
<OPTION VALUE="Platform">ApplicationPlatform
<OPTION VALUE="Application">Application
<OPTION VALUE="Team">SponsoringBU
</SELECT>
</td>
<td>
<SELECT NAME="choiceY" id="choiceY">
<OPTION VALUE="Count">ByCount
<OPTION VALUE="Percentage">ByPercentage
</SELECT>
</td>
<td style="padding-left: 3em">
<b>Choose A Graph Type:</b>
</td>
<td>
<SELECT NAME="graphType" id="graphType">
<OPTION VALUE="Bar">BarChart
<OPTION VALUE="Line">LineChart
</SELECT>
</td>
</tr>
<tr>
<td>
<a href="#" onclick="showGraphData();">Draw Graph</a>
<!-- <input type="submit" value="Draw Graph"/> -->
</td>
</tr>
</table>
<table>
<tr>
<td>
<iframe id="show_graph" name="show_graph" height="500px" width="950px" scrolling="no" frameborder="0" style="display:block"></iframe>
</td>
</tr>
</table>
In the Javascript function in above HTML, I have following:
<SCRIPT language="JavaScript">
function showGraphData(){
var theDivGraphData = document.getElementById('show_graph');
var theDivX = document.getElementById('choiceX');
var theDivY = document.getElementById('choiceY');
var graphType = document.getElementById('graphType');
var x = theDivX.options[theDivX.selectedIndex].value+","+theDivY.options[theDivY.selectedIndex].value+","+graphType.options[graphType.selectedIndex].value;
var graphURL = "/Birt/run?__report=DynamicRpt.rptdesign"+"&choice="+x;
theDivGraphData.src = graphURL;
}
</SCRIPT>
In the beforeOpen of the Data Set, I have following:
var y = params["choice"];
var z = y.split(',');
if (z[0] == "Country" && z[1] == "Count" && z[2] == "Bar"){
this.queryText = "";
}else{
this.queryText = "";
}
I only want to check if the HTML user selected attributes are passed successfully to BIRT script or not but I'm getting below exception:
The following items have errors:
ReportDesign (id = 1):
+ There are errors evaluating script "var y = params["choice"];
var z = y.split(',');
if (z[0] == "Country" && z[1] == "Count" && z[2] == "Bar"){
this.queryText = "";
}else{
this.queryText = "";
}
":

var z = y.split(',');
if (z[0] == "Country" && z[1] == "Count" && z[2] == "Bar"){
this.queryText = "";
}else{
this.queryText = "";
}
+ "
-----
A BIRT exception occurred. See next exception for more information.
Error evaluating Javascript expression. Script engine error: Report parameter "choice" does not exist.
Script source: /report/data-sets/oda-data-set[@id="8"]/method[@name="beforeOpen"], line: 0, text:
__bm_beforeOpen(). (Element ID:1)
Please help to suggest what am I doing wrong here. It says Report parameter "choice" does not exist. which is true as I'm passing the parameter thru query string URL.
Thanks,
Saroj
