This solution is: When user enters any data on the input field, the entered data is taken and using ajax call servlet method will be triggered, which returns the matched records in DB as JSON string. Then the response data will be shown as suggestion under input text field. You are commenting using your WordPress.

How TO - Autocomplete
Straight to the point. Thanks for sharing For me the example is working perfectly fine. I think you have the answer in your question itself. Change the content-type attribute of the page directive to use UTF-8 instead of ISO and it will solve the problem. I did not care much about the character set since I was using plain text for this example and the aim is to call the servlet asynchronously.
But that is a good catch. It is always better to use UTF-8 encoding in all the layers. I will update the code soon. Please do let me know whether this solved your issue. I simply removed the setContentType and setCharacterEncoding from the servlet treatment and everything works as expected.
Most Welcome! Thank you for letting know the solution that worked for you :. I really liked your post! The second argument of the post function is where the parameters are meant to be passed and it is the standard way of passing parameters when making AJAX calls using jQuery.
You can pass multiple pairs of parameters separated by comma's. Other than that, you can pass the vales as query string to the servlet url first argument you are passing. I have used Tomcat server here, you can use Jboss server also and deploy your project.
This pot explains how to retrieve plain text from servlet and update the part of the web page without reloading the whole page.
If you want to send more complex java objects like lists,maps etc you have to use JSON and Jquery together. How can i return error value from servlet page.
Following things i need 1. In my page may possible the user may give wrong username and password at the time what can i do. Thanks in advance Thanks in advance. For example, if you make ajax call to your servlet controller on a button click that is in your leftpanel. Working Example, index.I am using IE7. Please help me on this. Hi Siddhartha, I am not sure if this has something to do with browser.
Hi, I run your war file successfully. But U have specified that we can add a select query in DummyDB. Whether the data string in DummyDB. Please reply. You may also implement your getData String query method that returns the matched data. This class is just to demonstrate the functionality. In reality the data will come from database. Also, how can I add other parameters to send to the servlet?
Thus you can get the string entered by user in your script file in this case getdata. All other parameters passed are named in the url string? Do you recommend using a servlet or using a jsp to produce output? Can you help me how to solve this?See in list. So always better choice is considering the underlying in what technology we did the particular application technology only.

Thank u for help. I want to continue this autoComplete effect for sentences. Where should I need to do the modifications? Do I need to change the JQuery?
How to insert this code in my project. Great work.In the context of web applications currently under development, fast reloading of pages is one of the most important properties. A slow application will cost you users and search engine rank, because slow load times are one of the biggest factors in website bounce rate. The main advantage of AJAX is that it avoids refreshing the entire page.
In older form submissions, the entire page reloads and processes on the server. The most important point to remember is that AJAX is not a complex programming language or package.
AJAX facilitates responding to browser events and refreshes the web page by dynamically working on the underlying DOM tree structure. You can use AJAX together with JSP to counter the problem or reload the entire page even when the changes pertain to a limited set of controls on the web page.
AJAX achieves this by exchanging smaller amounts of data with the web server in each request. It is important to remember that you are working with individual fields rather than the entire page when you are working with AJAX. It is used for building static as well as dynamic web content. If your web page uses a lot of server side programming, then it becomes very processing intensive. As the dynamic content in the page increases, the response time for server side processing increases.
For example, if you are updating a control selected from a drop down in a form that has twenty fields, then the typical JSP processing would send all the twenty values to the server even if only one value has been changed. This is not required and makes the processing on the server side really slow. The integration of AJAX with JSP gives you an important tool to maximize the performance of your web applications without compromising on correctness or security of the data.
Consider the standard employee table as follows —. The server processes the request and sends back the response as XML data to the client. On the client side, the fields are refreshed based on the XML reply. The XMLHttpRequest object handles both synchronous and asynchronous requests initiated by the client. By default, it operates in the asynchronous mode which is a no blocking mode where other fields on the page can be updated while the server side processing is in progress. On the other hand if the synchronous mode is used then no other interaction on the page is possible unless the current processing completes.
AJAX is very helpful when used along with server side programming. Using AJAX, the web page on the client side will be refreshed only for the fields that are updated and the response time for the client will be very fast. Net based applications too.

Data on the drop-down list will be from a database table, e. I studied the NetBeans tutorial on this, but selecting a value from the drop-down list to appear in the HTML input text element isn't possible with that tutorial. Here's the link.

I should also point out that this is a crude method; while fine for small word lists it will output large numbers of suggestions with no filtering for longer lists and when more different characters are in the input field.
When I type "milyk w" it shows the suggestion "milky way"it is very nice but when I tried to type "milyk wy"it is not showing the suggestion. Comments for Not Ok: 2. Okay the JSON.
