How to do validation in jsp using javascript

how to do validation in jsp using javascript

The same way you do with any HTML page.
Catch the onclick/onsubmit event, do your validation in javascript and then allow/cancel the action as required.
However this is javascript validation only - javascript can never call JSP code.

How to pass value from JSP to Javascript?

I want to pass 2 integers to Javascript to do checking? How can I do that?

Well, it is very simple, Follow these steps.
1. Have a form with fields
2. On submit validate the form using javascript
3. If the javascript returns false do not submit the form
4. if the javascript returns true submit the form
5. The destination jsp page will handle the db operations.
1. <form name="frm1" action="dbcheck.jsp">
<input type="text" name="txt1">
<input type="button" value="submit" onClick="return validate();">
</form>
put the above piece of code in the <body> tag
2. Upon submit the js function validate() will be called :
<script language="javascript">
function validate() {
if(document.frm1.txt1.value="") {
alert("enter text");
return false;
else {
document.frm1.submit(); // i am not sure whether the () after submit is required or not
put the above piece of code in the <head> tag.
3. Now when the submit happens, the control goes to the dbcheck.jsp
this is dbcheck.jsp:
<%
String str = (String) request.getParameter("txt1");
------other db operations go here --------
%>
"txt1" is the field name of the textbox from the form u previously submitted.
all da best

How to display PDF in JSP using Iframe

Hi All,
I am using Struts 2. I am building my file in ActionClass with seperate Method like getGeneratedPDF() in which, I am setting header of response and writing into PDF.
This method will be called from JSP by this way
s:property value="getGeneratedPDF()" />
But It displayed Junk Characters , and this PDF is not static (already Generated). It is generated and build on Fly.
I have 2 questions 1 -- How to display PDF in JSP in proper way without Junk Character in it?
questions 2 -- How to display it in Iframe?
Please help me , If you know the solution.
Thanks in Advance,
Jimmy

It is generated and build on Fly.A PDF file is a binary file, not a text file, and you're trying to display it as String. Of course you would get "junk characters". Have you ever tried opening a binary file (pdf, doc, jpg, xls, etc) using a text editor like Notepad?
I have 2 questions 1 -- How to display PDF in JSP in proper way without Junk Character in it?Display it as binary stream, not as text stream. You can display it standalone, just let the link/form/addressbar URL point to some Servlet which writes the InputStream of the PDF file to the OutputStream of the response, along with a correct set of response headers (at least content-type, content-disposition and content-length), so that the browser can open it in the correct application (which is usually Acrobat Reader). If you want to embed the PDF file in a JSP, then one of the ways is indeed using the HTML <iframe> tag.
questions 2 -- How to display it in Iframe? Just let the iframe URL point to the aforementioned Servlet.
You can find here an example of a generic file servlet, you may find it useful to get the idea how to do it: [http://balusc.blogspot.com/2007/07/fileservlet.html].

How to crate custom usage analytics using javascript

hi friends
i am working on usage reports in sharepoint 2013.
i need to show user infromation in reports, like most visited and least visited user names. but it is not possible through out of the box functionalities. how to do that using javascript.

Hi,
According to your post, my understanding is that you wanted to custom the usage analytics report.
Per my knowledge, we can see the top visitor and least visitor with the out of the box feature.
In the Site Collection Web Analytics Reports, there is an option called Top Visitors, it shows the top visitor and least visitor.
You can custom the report by clicking the Customize Report button on the Analyze tab of the ribbon.
Or you may create your own analysis with data in WSS_Logging database:http://social.technet.microsoft.com/Forums/en/sharepoint2010setup/thread/8ba7b6e9-0b5d-4c4b-bd66-d2c72bb538b3

How to set style !important using javascript??

i can set an items width using js
page_item.style.width = "400";
how do i incorporate the "!important" flag in this statement?

Hi Craig,
Here's the only blurb I could find on this:
http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/reference/properties/important.asp
Notice the "Scripting: N/A" bit at the top.
I use this site a lot - not because I'm particularly keen on MS/IE but because at the bottom of each entry you get confirmation of whether or not the setting/attribute/etc is standard or not and the pages are kept up to date.
I have to say that this is only the second time I've come across someone trying to use this. The first time we just decided to leave it. I can see the importance of using it to stop someone overriding styling, but as I mentioned above, it is possible to create an entire script tag using javascript and, therefore, you can override it. Seems silly to me, but there you go!
It would also be better, in my view, if they had used a better word for this setting - something like java's "final" - as, the first time I saw it I took it to mean "make more bolder" or "highlight it" or somesuch thing.
Regards
Andy

How to execute a batch file using javascript

Hi,
I dont know java. i have a batch file to do my task. Im designing the front end with HTML.Can anyone tell the command to execute batchfile using javascript
Message was edited by:
viswanath_java

Java and not JavaScript are not the same thing or even close to the same thing. You appear to be in way over your head. It might be a good time to fess up to your employer that you are underqualified.
Apart from the JavaScript faux pas your question is also lacking because
- you don't identify what this batch file is or does or needs to execute in
- it is very difficult to understand how the front end for this will be HTML
It seems you may one day want something like a Servlet. But you are long way from implementing this solution.
