I\'m trying to complete some ajax requests to insert a textarea into a database without refresh. Here is my code:
HTML:
</script> <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-5408099190056760" data-ad-slot="7305827575" data-ad-format="auto" data-full-width-responsive="true"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> </div> <div class="relativetags"> 相关标签: </div> </div> <div class="fly-panel detail-box" id="flyReply"> <fieldset class="layui-elem-field layui-field-title" style="text-align: center;"> <legend>2条回答</legend> </fieldset> <ul class="jieda" id="jieda"> <li data-id="111"> <a name="item-1111111111"></a> <div class="detail-about detail-about-reply"> <a class="fly-avatar" href="https://www.e-learn.cn/qa/u-52.html"> <img src="https://www.e-learn.cn/qa/data/avatar/000/00/00/small_000000052.jpg" alt=" "> </a> <div class="fly-detail-user"> <a href="https://www.e-learn.cn/qa/u-52.html" class="fly-link"> <cite>闹比i </cite> </a> </div> <div class="detail-hits"> <span>2020-12-15 15:08</span> </div> </div> <div class="detail-body jieda-body photos"> <p>Tried and working. you are using,</p> <pre><code><textarea name='Status'> </textarea> <input type='button' onclick='UpdateStatus()' value='Status Update'> </code></pre> <p>I am using javascript , (don't know about php), use id ="status" in textarea like</p> <pre><code><textarea name='Status' id="status"> </textarea> <input type='button' onclick='UpdateStatus()' value='Status Update'> </code></pre> <p>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</p> <pre><code><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> </code></pre> <p>and jsp is like </p> <pre><code>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); } </code></pre> <p>}</p> <div class="appendcontent"> </div> </div> <div class="jieda-reply"> <span class="jieda-zan button_agree" type="zan" data-id='1208897'> <i class="iconfont icon-zan"></i> <em>0</em> </span> <span type="reply" class="showpinglun" data-id="1208897"> <i class="iconfont icon-svgmoban53"></i> 讨论(0) </span> <div class="jieda-admin"> </div> </div> <div class="comments-mod " style="display: none;
