OnClick Send To Ajax

I'm trying to complete some ajax requests to insert a textarea into a database without refresh. Here is my code: HTML:

Solution 1:

<textarea name='Status'> </textarea>
<input type='button' value='Status Update'>

You have few problems with your code like using . for concatenation

Try this -

$(function () {
    $('input').on('click', function () {
        var Status = $(this).val();
        $.ajax({
            url: 'Ajax/StatusUpdate.php',
            data: {
                text: $("textarea[name=Status]").val(),
                Status: Status
            },
            dataType : 'json'
        });
    });
});

Solution 2:

Tried and working. you are using,

<textarea name='Status'> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>

I am using javascript , (don't know about php), use id ="status" in textarea like

<textarea name='Status' id="status"> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>

then make a call to servlet sending the status to backend for updating using whatever strutucre(like MVC in java or anyother) you like, like this in your UI in script tag

<srcipt>
function UpdateStatus(){

//make an ajax call and get status value using the same 'id'
var var1= document.getElementById("status").value;
$.ajax({

        type:"GET",//or POST
        url:'http://localhost:7080/ajaxforjson/Testajax',
                           //  (or whatever your url is)
        data:{data1:var1},
        //can send multipledata like {data1:var1,data2:var2,data3:var3
        //can use dataType:'text/html' or 'json' if response type expected 
        success:function(responsedata){
               // process on data
               alert("got response as "+"'"+responsedata+"'");

        }
     })

}
</script>

and jsp is like

the servlet will look like:   //webservlet("/zcvdzv") is just for url annotation
@WebServlet("/Testajax")

public class Testajax extends HttpServlet {
private static final long serialVersionUID = 1L;
public Testajax() {
    super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    String data1=request.getParameter("data1");
    //do processing on datas pass in other java class to add to DB
    // i am adding or concatenate
    String data="i Got : "+"'"+data1+"' ";
    System.out.println(" data1 : "+data1+"\n data "+data);
    response.getWriter().write(data);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    doGet(request, response);
}

}
