How to validate a text field??

Can any one tell me hot to validate a text field??
I want to create a text field which holds alphabets only..

You can use simple javascript code in the liveChange function such as the following (for sap.m.Input):
liveChange: function(evt) {
var inputValue = evt.getSource().getValue();
this.setValueState(me.validateTagName(inputValue));
 this.validateTagName = function(inputValue) {
 if (inputValue.trim().length < 1) {
 return "Error";
 } else {
 return "None";

How to Validate the Text Field in JSF

Hi,
I am facing a issue to validate the text field where the below code accepts (space' ',underscore'_',pipe'|') symbol as a first character and last character.Where by it can accept in the middle.
It should not accept special characters also. Below code is working properly for special characters.
<tr>
<td width="30%" align="right"><h:outputText id="aAccrualType" value="Accrual Type" /> *</td>
<td width="50%">: <h:inputText id="accrualType" value="#{accrualTypeMast.accrualType}" required="true" >
<t:validateRegExpr pattern="^[(a-z)||(A-Z)||(0-9)||(_)||(\s)||(/)]+$" />
<f:validateLength minimum="1" maximum="50"/>
</h:inputText>
<h:message for="accrualType" showDetail="true" style="color:red" />
</td>
</tr>
The thing is i dont have much knowledge in regular expression.
Is there any other way to do this.
Could anyone help me in this.
Thanks,
Ambika☺

This has nothing to do with JSF.
I suggest you to read the Pattern API documentation [1]. You can easily create a small Java Application and test the regexp using String#matches() as it uses the same regexp guidelines.
public static void main(String[] args) {
 String regexp = "^[a-z]+$";
 String value = "foo";
 boolean match = value.matches(regexp);
 System.out.println(value + " matches " + regexp + ": " + match);
}[1] http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Pattern.html

How to validate empty Text Field?

Hi,
I am Thirupathi,
I am new to JSF. I am able to validate the value of a component which has some value using attribute
validator="#{UserNumberBean.validate}"
in this case it is calling validate method of UserNumberBean.
but if i keep the field empty then it is not calling that validate method of UserNumberBean.
Please can any one clarify my doubt.
wait for reply
Thanx in advance.

validate method is called to validate the correctness of the value input by user (eg. email format, phone numebr etc.). If user leaves the input box empty then there is nothing to validate and so validate is not called.
If you want customised messages for required fields you can use requiredMessage attribute in your inputText tag provide that you are using JSF1.2. It is not available in JSF1.1. In JSF1.1 it is requires some extra coding. You can do like this :
In your managed bean
public class MyBean {
 private String userName = "";
 private String password = "";
 private ArrayList errors = new ArrayList();
 public String getErrors() {
 String message;
 if (errors.size() == 0) {
 message = "";
 } else {
 message = "<UL>\n";
 for(int i=0; i<errors.size(); i++) {
 message = message + "<LI>" +
 (String)errors.get(i) + "\n";
 message = message + "</UL>\n";
 return(message);
 public String validateUser() {
 errors.clear();
 if (userName == null || userName.trim().length() == 0) {
 errors.add("User Name is required");
 if (password == null || password.trim().length() == 0) {
 errors.add("password is required");
 if (errors.size() > 0) {
 return(null);
 } else {
 //perform your logic here
 return("returnString");
}In your jsp page, include the errors tag as below. It will show all errors on top of the page.
<f:view>
 <h:form>
 <h:outputText value="#{MyBean.errors}" escape="false"/>
 User Name: <h:inputText value="#{MyBean.userName}" />
 Password: <h:inputText value="#{UserBean.password}" />
 <h:commandButton value="Login" action="#{UserBean.validateUser}" />
 </h:form>
 </f:view>One point to remember is to clear the errors List in every action.
Hope it helps.

Hi,
I presume you are talking about a report display in ALV and u wish to add a column to it .
If it is a global requirement ,as in table being used there in ALV can be modified, then you can append the table and the system should pick up the same automatically from there.
Otherwise , you can make a Z program . Modify the catalog being used in ALV.

pabi

Hello Pabitra,
I had a similar issue in my Project.
Please verify if the SMOD enhancement MBCF0002 (EXIT_SAPMM07M_001) is active in your system.
If this is the case, verify from two angles:
a) Whether the Enhancement was accidentally activated - If yes, then De-activate the same
b) If there is some logic coded in the User Exit, but, the Text is somehow not determined...even the existing content in the text field (input to EXIT_SAPMM07M_001) will get vanished.
Hope that your problem will be resolved by this. Pls reward points.

How to autopopulate a text field with unique data from multiple data sets

Hi,
I'm a laboratory manager in charge of a hospital project which will be using pdf forms to send and receive data from our end users across the city. I need help with the last part of our pdf form, specifically with a js that will do a bit of text-field autopopulation magic. This, unfortunately, is a beyond what I have taught myself about pdf js functionality.a
The problem:
I need to provide my end users with a text field containing a set of data [A, B, C, D, E, F ...] and the total items in this set [tot#]. The end user needs this information as part of the implementation of this particular laboratory machine.
The particulars
When the end user asks for an experiment to be run, we must specify some pieces of data to help them interpret the results. These are constructed as panels which contain discrete data elements.
For example - One experiment may use two panels, Panel#1 and Panel #2. Panel #1 includes the items A, B, D, E, Panel #2 includes the items A, B, C, F, G.
Thus, the panels may share some of the same items, but, I only want the unique members to be displayed in the text field. If I make a drop down box or checkboxes with the panels, I want to be able to select the panels that we ran and (in this example) have the text field display only the unique items among all the panels that were used:
textfield outpute = A, B, C, D, E, F, G - 7 total.
Any assistance from the pdf community would be very much appreciated.
Thanks!

Thanks for that help.
I should have made it more apparent that I'm very new to scripting and I'm
not a programmer by trade. I have a few questions before modifying the code
you kindly provided.
1) Where should I embed this script? Within the 'selection change' area of
my listbox?
2) Can I replace the term 'arr' with the names of the various items in my
listbox or should I put 'arr#' as the output value for each term?
3) Will this script find and display the unique values when a user selects
multiple items in my listbox?
4) How does the script know where to output the unique members of the
combined set?
I appreciate your patience with me.

How to get the text field in the header for only first page of the report

Hi,
I am developing reports in BI Publisher Enterprise where i am facing problem i.e., i have to get some text field in header,for only first page in the result but it is displaying in all the other pages of the report in result.So,please if you have any idea of how to solve it, please reply.It is required as early as possible.
Thanks in Advance

Invalid path? What are you doing? Writing the report output to an invalid directory?
Where are your terms and conditions? It would be very easy just to put them in a database table and select them in your report query.

How to allow input text field to accept more than one "specific" answer.

Hi,
I am working for something and trying to create a type-box-based quiz for one of my classes, where an input text field can change it's border color if 2 or more words from an accepted word list is inputed.
For example, Say a list has possible answers: R,G, B, Y for the question "Name 2 colors".
I want to create an input text box where the border of the box will change color if any 2 letters (in the above list) are entered into it.
I've tried setting up a variable NumberSuccesses and setting it so that the number increases by 1 for each letter entered e.g.
if (Ex.text == "R");
NumSuc = NumSuc +1; // the var NumSuc has already been defined earlier in the code
If (Ex.text ''G")
NumSuc = NumSuc + 1
if (NumSuc == 2)
Ex.borderColor = 0x0000FF
but that didn't work.. and I tried doing it with another function which I use for multiple input boxes like if there were boxes A, B, C. I could set up a general function where if the correct answers were entered into A, B, an C respectively, only then will say, a checkmark show up using a
EnableCheckmark (); type function. Not sure how to do it if it's the same text input box though. Also just tried adding it into the same function re.
If (Ex.text == "R" + "G")
Ex.borderColor = 0x0000FF
.. Does anyone know what else I can do?

The solution of Nishu with Evaluation Logic:
//These Are the Possible Answers
var solutions:Array = new Array("A","B","C","D");
function testInput(_inputText:String):Boolean
 //the delimiter could also be a comma, here it is a space
 var inputStringArray:Array = _inputText.split(" ");
 var counter:Number = 0;
 for (var i:int=0; i<inputStringArray.length; i++)
 for (var j:int=0; j<solutions.length; j++)
 if (inputStringArray[i]== solutions[j])
 counter++;
 if (counter >=2)
 trace("true");
 return true;
 else
 trace("false");
 return false;
//Textfield with name input_txt on stage
input_txt.addEventListener(TextEvent.TEXT_INPUT, answerTxtInp);
// The function that will be called by the event listener
function answerTxtInp(txtEvent:TextEvent):void
 // depending on the possible answers of characters, change the border color
 if(testInput(input_txt.text)){
 input_txt.borderColor = 0xFF0000;
 else{
 input_txt.borderColor = 0x000000;

How to auto complete text field

Hello!
I have the following behavior request for a text field.
An user must write a date in a text field. The date format is yyyy/MM/dd (as 2003/02/04). The user would begin writing "2003" followed by the "0" character but would see in the text field "2003/0". The "/" would be automagically putted there.
I hope this table will make the behavior more clear.
User User
writes sees this in the text field.
2003 2003
20030 2003/0
200302 2003/02
2003020 2003/02/0
20030201 2003/02/01
Also, if the user deletes the characters "1" and next the "0" from the previous example, it would automatically erase also the "/" character.
Could someone point me to some sample code or give me some clues how to implement the previous behaviour? Does this pattern behavior has some well know name, where I can "google" for?
Thanks!
Eduardo
