Servlets :: How To Call JavaScript Function Or JQuery Modal Box
Mar 18, 2015
i don't need ordinary javascript alert box. so i was use the jquery modal alert box for different action like success, error etc.but i have problem to call the alert box within servlet.
I have a problem with a JavaScript application on Safari 6 and 7. The application updates a smartcard on a website, through a JAVA applet using JavaScript requests.
There is no problem with other browsers. On Safari , randomly (1 smartcard's update on 10), the javascript completely freezes in the middle of an update (on a random card).
After 5 minutes exactly, the javascript resumes, and 2 behaviors happens : the update wether continues or stops completely.
We investigated a lot about this problem , at network and memory level. We use a lot of "setTimeOut" function (approximately 1100 times), and read that setTimeOut could cause problems with memory management on Safari.
I've a simple logic Code to increment a variable from javascript and Send it back to jsp. I just writing simple code to explain the logic. My code will have scritplets. I know usage of scriptlets is inside jsp is oldest but for the sake of logic.
<!--Jsp Page --> <% int i=0; <input type="button" onclick="fun()"/> %> <!-- Script as Follows--> <script> function fun(){ <%i++;5> } </script>
But My value of i is not incrementing its showing that function is undefined
get updated bean property in javascript function. This function I am calling from <a4j: commandbutton> this button is having actionListner, which is updatin bean property based on some User selection. When this action is completed then I am calling javascript function in oncomplete. But that javascript function is not taking updated bean value, it is always taking first value.I can't use hidden text as there are some drop downs which User will selct and then hit commandbutton which will update bean property.
I have an arraylist in my servlet which i need to pass to jsp as a response for a javascript call. This is an arraylist of DTOs. There are 24 DTO objects in the list. The DTO has an int variable and a HashMap. And i need to pass this into the javascript code in my jsp page. Do i use json? Do i send the entire list as a json object or should i iterate through the arraylist (from servlet) and serialize all the DTOs and pass that to the jsp?
In a form i used <h:commandButton> i called a Javascript function. Though the function returns false , form is submitted and action method is called. I used like this
my first assignment is to convert a md5 string to password of the user, the MD5 function is available, i just need to call it and print the result. Here is my code. I can't call the md5 because of the String[] and String is different in main and md5 function,modify the code so it can run properly, also the input has to be entered from command line.
import java.security.*; public class PasswordCracker { public static void main (String[] args){ String password; md5(args) System.out.printf(""+password+"");
import java.io.BufferedReader; import java.io.InputStreamReader; public class vowels{ public static void main(String arg []) { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.print("Enter a String : ");
I have understood my programming class up to this point and now I have been given a lab that I can't figure out for the life of me. Here what I have to do: Write a program that will call a method (called f) to calculate the following function" f(x)=(x^2)-16...this is what the output should be:
I've got a banner that displays on the web page and users can close it out by clicking an "X" button in its corner. Once it's closed, we track for that session that it remains closed, so a cookie gets set. I'd like subsequent requests to the server to be aware of this cookie so that the banner code is just not included in subsequent responses. (Sidebar: earlier I was just detecting the cookie after page load and then hiding the banner but it creates a lag where the banner is visible then suddenly pops away, making for poor user experience.)
I expect that even though Javascript set the cookie it would then show up in HttpServletRequest.getCookies() call, but there's actually a lot of cookies visible in Chrome Developer Tools on the client of my page that don't show up in .getCookies(). Does the HttpServletResponse.addCookie need called at some point first for the cookie to be passed back and forth to server?
I need to check in my java class the status of the javascript (whether it's enabled or disabled) and based on that few validations will be performed at server side.
If have to use noscript, then any small example for xhtml. My project works on Spring web flow.
My task is that i want to read text from a webpage, [URL] ...., in my server that shows only the following inside brackets
{ "VERSION": "2.00.000" }
I am using a js that has all the necessary functions of the project, the function for the button that will show a modal and currently is static, is like that
var imgAbout = $('#topright-menu ul.menu-divmenu > li > a > img[src$="about.png"]'); imgAbout.click(function(e) { e.preventDefault(); var modal = (self.modal()); var content = "Version: 2.00.000 <br><br>" +
[Code] ....
I need to understand the mechanism that will accomplish such a task,, in general how can i do that ??,,
And the servlet handles the HEAD method in the sense that the doGet() method returns if the method type is HEAD.When I run it, the servlet returns the code returned by the entire doGet() method. This shows that the doGet() method does not realize that it is a HEAD method and it should return back without processing further.The application server is Tomcat 4.0.
I am a JSP/Servlet newbie currently adding the first servlets to a web site that had been static all along. My local instance worked great but the servlets did not respond on the test instance. Apparently, my hosting service provider requires me to use an invoker servlet mapping.
Adding this to local web.xml broke the application but the servlets respond on test instance (when their calls are not preceded by another servlet call). A Servlet fails when it is called immediately after another servlet has been called.
What I saw happening on test is URL for first call is of the form:
The servlets are invoked using "href=servlet/<servlet-name>?Id="
How can I avoid the inclusion of 'servlet' in the URL and reset the URL to the JSP page it navigates to after processing of the servlet?
P.S.: I am also trying to enable the Invoker servlet on local so I can troubleshoot easier. I went through the changes to Tomcat's web.xml and context.xml. However, my local servlets did not respond even after calling them using "href=<servlet-name>?Id=". Is there a way I can check if my invoker is active?
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub String delete = ("DELETE FROM anagrafica WHERE Nome = ? And Cognome = ?"); ConnectionManager cm = new ConnectionManager(); String Nome = request.getParameter("nome"); String Cognome = request.getParameter("cognome");

and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.
The above code works great and displays date picker with next and previous button but when I use same code on a jsp page the buttons to go back to previous and next month does not show up.

I am using Spring to develop a web application.I have used JQuery ui in HTML page it is working fine a Dialog box appear with JQuery effect.But When I use the same procedure in jsp it is not working.Here is my code of jsp file
