The rescuer:

ajaxonload

Ajaxonload will be called just below the radio control. By this when the page is loading the javascript will be called only after the controls are generated.

<cfset ajaxonload(‘changeSelection’)>

By the way it may be so simple. But it took a hell lot of time in my development. … So thought to share..

An example code for Excel File Creation

//creating the workbook using poi
<cfset workBook = createObject(“java”,”org.apache.poi.hssf.usermodel.HSSFWorkbook”).init()/>

//assigning style to the cells in the excel sheet
<cfset cellstyle = workbook.createCellStyle()>
//assigning font weight
<cfset fontface = workbook.createFont()>
<cfset fontface.setBoldweight(fontface.BOLDWEIGHT_BOLD)>
<cfset cellstyle.setFont(fontface)>

//this is the sheet counter for the excel work book. for our example it is 3.
<cfset sheetcounter = 0>

<cfloop from=”1″ to=”3″ index=”sheetcounter”>
<cfset newSheet = workBook.createSheet()/>
<cfset row = newSheet.createRow(0)/>

//this is the student list. We will create sheets for these students
<cfset studentlist = “balu,pinky,deepu”/>
<cfset subjectlist = “science,maths,english,computer”/>

<cfloop list = “#studentlist#” index=”student”>
<cfset workBook.setSheetName(#sheetcounter#, “#student#”)/>
//this is for creating headings for each sheet.. ie the subject names science,maths,english,computer
<cfset counter = 0>
<cfloop list=”#subjectlist#” index=”header”>
<cfset cell = row.createCell(counter)/>

<cfset cell.setCellStyle(cellstyle)/>
<cfset cell.setCellValue(#header#)/>
<cfset counter = counter+1>
</cfloop>

<cfset sheetcounter = sheetcounter+1>
</cfloop>
</cfloop>

//the resultset name is studentdetails. We are looping through the query in order to assign the values to the cells of the excel sheet.

<cfloop from = “1″ to = “#listlen(studentlist)#” index = “datacounter”>

<cfset currentsheet = workBook.getSheetAt((datacounter-1)>
<cfset row = currentsheet.createRow(1)/>
<cfset datasheetcounter = 1/>

//getting data from the table student

<cfquery name=”studentdetails” datasource=”studentdb”>

select * from studentdetails where studentname = ‘#datacounter#’
</cfquery>

<cfif studentdetails.recordcount>

//looping through the student details
<cfloop query=”studentdetails”>

<cfset row = currentsheet.createRow(datasheetcounter)/>

<cfset cell = row.createCell(0)/>
<cfset cell.setCellValue(studentdetails.science)/>

<cfset cell = row.createCell(1)/>
<cfset cell.setCellValue(studentdetails.maths)/>

<cfset cell = row.createCell(2)/>
<cfset cell.setCellValue(studentdetails.english)/>

<cfset cell = row.createCell(3)/>
<cfset cell.setCellValue(studentdetails.computer)/>

<cfset datasheetcounter = datasheetcounter + 1>

</cfloop>
</cfif>

</cfloop>

//this is the directory where we are going to save the excel file
<cfset directorypath = “d:\studentdetails”/>

<cfif NOT DirectoryExists(directorypath)>
//creating the directory if the directory is not there in the server
<cfdirectory action=”create” directory=”#directorypath#” >

</cfif>

<cfset fullpath= “d:\studentdetails\studentdetails.xls”/>
//if the file is there in the directory we are deleting that file
<cfif FileExists(fullpath)>
<cffile action=”delete” file=”#fullpath#”>
</cfif>

//writing the file
<cfset fileOutStream = createObject(“java”,”java.io.FileOutputStream”).init(#fullpath#)/>
<cfset workBook.write(fileOutStream)/>
<cfset fileOutStream.close()/>

Here is how we do that

<cfif CGI.HTTP_USER_AGENT contains “MSIE”>

<!— All other browsers—>

</cfif>

<!— this is the dsn —>
<cfset var dsn = “mydsn”>
<cftry>
<!— this is to create the object of the service factory —>
<cfobject action=”create” type=”java” name=”servicefac” class=”coldfusion.server.ServiceFactory”>
<!— getting the data source service —>
<cfset datasourcesrvce =servicefac.getdatasourceservice()>
<!— checking whether the dsn exists —>
<cfset existdsn = datasourcesrvce.verifydatasource(dsn)>
<!— dsn exists if not going to catch —>
<cfcatch type=”any”>
<!— dsn dont exist —>
<cfset existdsn=”false”>
</cfcatch>
</cftry>

Setting a normal variable

<cfscript>

myvariable = “balu”;

</cfscript>

Do / While Loop

<cfscript>

myvariable = 1;

do {

myvariable  = myvariable + 1;

WriteOutput(myvariable);

} while (myvariable LTE 0);

</cfscript>

While Loop

<cfscript>

myvariable = 0;
while (myvariable LT 10) {
myvariable = myvariable + 1;
WriteOutput(myvariable);
}
</cfscript>

Try / Catch Statements

<cfscript>

try {
x = 10 / 0;
}
catch(Any e) {
WriteOutput(“Error occured ” & e.message);
}
</cfscript>

Single Line Comments

<cfscript>

a = a + 10; //This is a single line comment
</cfscript>

Multi-Line Comments

<cfscript>

/* This is a multi line comment
that can written in
multiple lines
*/
</cfscript>

FOR Loop

<cfscript>

for (i=1;i LTE ArrayLen(array);i=i+1)
{
WriteOutput(array[i]);
}
</cfscript>

Switch Case

<cfscript>

switch(myvalue) {
case “1″:
WriteOutput(“1 is the value”);
break;
case “2″:
WriteOutput(“2 is the value”);
break;
default:
WriteOutput(“default value”);
}
</cfscript>

If… else….

<cfscript>

if (myvariable EQ 1) {
WriteOutput(“1 is the value”);
}
else if (myvariable EQ 2) {
WriteOutput(“2 is the value”);
}
else {
WriteOutput(“default value”);
}
</cfscript>

CFQuery in CFScript

Normally we use like
<cfquery name=”getstudents” datasource=”dsnstudents”>
select stuname,stuage,stuclass from students where stuid > 1
</cfquery>

In CFscript

<cfscript>

objFactory = CreateObject(”java”,”coldfusion.server.ServiceFactory”);
objDataService = objFactory.DataSourceService;
objDataSource = objDataService.GetDataSource(”dsnstudents”);
objConnection = objDataSource.GetConnection(Enter the username and password here);
objstatementstring = “select stuname,stuage,stuclass from students where stuid > 1?;
objStatement = objConnection.PrepareStatement(objstatementstring);
objResults = CreateObject(”java”,”coldfusion.sql.QueryTable”).Init( objStatement.ExecuteQuery() );
objConnection.Close();
</cfscript>
