ColdFusion is converting a string to number when passing to JS via a SerializeJSON and deSerializeJSON.
This is only happening when an 'E' is used between two set of numbers. like 3E6, 65E3, 56e45 etc. This is the code inside cfscript.
x = "2e9";
writedump(SerializeJSON(x));
writedump(deSerializeJSON(SerializeJSON(x)));
Output:
2.0E9 2000000000
Please suggest, if is there any other way for such issues.
It is this: https://bugbase.adobe.com/index.cfm?event=bug&id=3695627: "SerializeJSON turns strings that look like scientific notation into floats."
It's a known bug in CF9, and it's fixed in CF10.
In the meantime, you will just have to pad the string with something to force ColdFusion to not see it as a number in scientific notation.
Or upgrade to CF10 (CF9 is end of life next month, btw). Or to Railo.
I have resolved this using below solution
let's say ItemUnit = 12E45
stcReturn.firstname = "Yes";
stcReturn.lastname = "Man";
stcReturn.ItemUnit = "12E45"
error output after deSerializeJSON stcReturn.ItemUnit = 12e+46
<cfset stcReturn.ItemUnit = ItemUnit />
<cfset StructSetMetaData(stcReturn.ItemUnit, {ItemUnit :
{"type":"string","name":"ItemUnit"}})/>
deSerializeJSON(stcReturn)
Correct Output:12E45

I'm exporting a query to an Excel file using cfspeadsheet. It's working and creating the Excel sheet. However, the problem is that one of the columns, ie card_number, contains a 15 digit number, which is displayed like this: 4.5421E+15. Is there a way I can display the full number instead: 4254218068670980 ?
<!--- create manual query for demo --->
<cfset qData = queryNew("")>
<cfset queryAddColumn(qData, "NumericCol", "BigInt",["4254218068670980"])>
<cfset queryAddColumn(qData, "StringCol", "Varchar",["4254218068670980"])>
<cfset queryAddColumn(qData, "DecimalCol", "Decimal",["4254218068670980"])>
<!--- export to file --->
<cfspreadsheet action="write"
filename="c:/path/to/myFile.xls"
query="qData"
overwrite="true">
You need to define and use a format for the cell to show complete number. Below is a sample code snippet for your code:
<cfscript>
theFile=GetDirectoryFromPath(GetCurrentTemplatePath()) & "new_data.xls";
//Create a new Excel spreadsheet object.
theSheet = SpreadsheetNew("Expenses");
//Set the value a cell.
SpreadsheetSetCellValue(theSheet,"4254218068670980",1,4);
//Set value into another cell.
SpreadsheetSetCellValue(theSheet,"4254218068670980",2,4);
// Define a format class for for number.
longNum=StructNew();
longNum.dataformat = "0";
//Now use this class to format cell
SpreadsheetFormatCell(theSheet,longNum,2,4);
</cfscript>
There are many supported formats available; for a complete list you may check here.
Also, just like SpreadsheetFormatCell you may want to use SpreadsheetFormatColumn or other related functions.
(Too long for comments...)
FWIW, CFSpreadsheet is designed for very simple exports, without a lot of bells and whistles. If you need special formatting, you must use spreadsheet functions instead.
The closest equivalent to your current code is probably the SpreadsheetAddRows(sheet, query) function. It populates a worksheet with the data in the supplied query object. As Viv's answer mentions, you can then format the columns as desired. For example, if you want the value to be treated as text, use {dataformat = "#"}:
<cfscript>
SpreadsheetAddRows(theSheet, qData);
SpreadsheetFormatColumns(theSheet, {dataformat = "#"}, "1-3");
SpreadSheetWrite(theSheet, "c:/path/to/myFile.xls", true);
</cfscript>
As an aside, the examples in the documentation are not always the best or cleanest. Consider them a starting point, rather than using the code exactly "as is" ..
I'm trying to modify existing codes in my ColdFusion application left by previous programmer. I don't understand the meaning of this line of code (the one with question marks):
<cfset Application[#form.username#] = 0> ??????
<cfset Session.loggedin="Yes">
<cfset Session.username="#Trim(Form.username)#">
Maybe I haven't been working with CF long enough to see this syntax so I don't know what this mean.
When setting an application variable I usually use this syntax:
<cfset application.variableName = "some value">
Can someone explain to me what is this ?
Thank you
As well as explicitly stating variable names at "code time" with dot notation, CFML allows one to reference them dynamically at runtime via a string value.
This is done via associative array notation (using square brackets), eg:
myVariableName = "foo";
variables[myVariableName] = "moo"; // equivalent to variables.foo = "moo"
I'm a bit stumped on this one..
I currently have a string.
Please enter your variable.firstname here
What i would like to do is find the variable.firstname in the string and convert it to be used as #variable.firstname#
Im using CF8, and ive looked at using findNoCase() but the variable.firstname portion can appear anywhere. I am also trying to use this in a Coldfusion Custom Tag as its to simply display the firstname of the user that could be dynamically populated.
I cant use any other functionality to change it IE = variable['firstname] because the variable could be the result of a dynamic variable i pass in and the query for the content will reside within the custom tag.
<cfset yourNewString = replace(yourOldString,'variable.firstname',
'##variable.firstname##', 'all')>
Note the double pound signs.

I'm not sure I understand exactly what you're saying here but if you're saying that variables.firstname is coming from another variable and the .firstname is the dynamic part you could still use array notation.
<cfset myName = "Travis">
<cfset yourName = "user125264">
<cfset myCustomVariable = "myName">
<cfoutput>Hi, My name is #variables[myCustomVariable]#. </cfoutput>
<cfset myCustomVariable = "yourName">
<cfoutput>Your name is #variables[MyCustomVariable]#.</cfoutput>
Output: Hi, My name is Travis. Your name is user125264.
If that isn't what you meant, I apologize.
If you're trying to replace variable.firstname with #variables.firstname# and then also get the value of that variable, you'll need to do the replace <cfset yourNewString = replace(yourOldString,'variable.firstname',
'##variables.firstname##', 'all')> and then wrap the resulting string in an evaluate() function (and an inner de() to prevent CF from evaluating everything): <cfset evaluatedString = evaluate(de(yourNewstring))>.
If there are more variables besides variable.firstname that need this kind of translation, you'll need to get into regex with reReplace() to catch them all in one statement. My regex is rusty, so you'll need to Google that bit on your own. ;o)
This is my code:
returnStruct.myList = myList;
returnStruct.first = trim(ListGetAt(myList,3));
returnStruct.last = trim(ListGetAt(myList,13));
returnStruct.address = trim(ListGetAt(myList,15));
returnStruct.city = trim(ListGetAt(myList,2));
returnStruct.state = trim(ListGetAt(myList,9));
Everything is working fine until myList hits empty values and then everything crashes.
I found a command "includeEmptyValues" that I can set to 'yes' but I am not familiar with it and the documentation of ColdFusion 9 isn't the best I've come across.
http://cfquickdocs.com/cf9/#listgetat
Previous versions of ColdFusion (and CF9 by default) counted consecutive delimiters as a single delimiter. So a list that looked like this:
<cfset myList="a,b,,c,,d" />
was considered to have four elements.
Recently added is the "includeEmptyValues" attribute.
listGetAt(list, position [, delimiters, includeEmptyValues ])
So while
<cfset myVar=listGetAt(myList,6) />
will throw an error
<cfset myVar=listGetAt(myList,6,",","true") />
will successfully set myVar to d.
might want to use listToArray(), and ArrayIsDefined(). Play with includeEmptyFields attr and see which behavior you prefer. True = Convert empty elements in a list to empty array entries
How would I use use a string function to select everything in a variable after the last "/"
http://domain.com/g34/abctest.html
So in this case I would like to select "abctest.html"
Running ColdFusion 8.
Any suggestions?
Um, a bit strange to give very similar answer within few days, but ListLast looks as most compact and straightforward approach:
<cfset filename = ListLast("http://domain.com/g34/abctest.html","/") />
And yes, IMO you should start with this page before asking such questions on SO.
Joe I'd use the listToArray function, passing the "/" as the delimiter, get the length of the array and get the value in the last slot. See sample below
<cfset str = "http://domain.com/g34/abctest.html"/>
<cfset arr = ListToArray(str,"/","false")/>
<cfset val = arr[ArrayLen(arr)]/>
<cfoutput>#str# : #val#</cfoutput>
produces
http://domain.com/g34/abctest.html : abctest.html
