jQuery Ajax调用servlet

Question

I am trying to make an Ajax call using JQuery to a servlet that returns a JSON object. In the JSP page I have a form, at first I didn't know how the get the data from the form, then I found .serialize.

I have the following JavaScript:

$(document).ready(function() {
    $("#submit").click(function blabla() {
        var formData = $('form').serialize();
        $.ajax({
            type: "POST",
            url: "/ArchiveSearch/Search",
            dataType: "json",
            data: formData,
        });
    });
});

The information comes from the following form:

<form method= post">
            <div class="searchCiteria">
                <div id="searchValueBlock1">
                        <div><span class="label">Case ID:</span><input type="text" name="messagecaseid"  size="25"/></div>
                        <div><span class="label">Onderwerp:</span><input type="text" name="messagesubject" size="25" /></div>
                        <div><span class="label">Afzender:</span><input type="text" name="messagesender"  size="25"/></div>
                        <div><span class="label">Ontvanger:</span><input type="text" name="messagereceiver"  size="25"/></div>
                </div>

                <div id= "searchValueBlock2">
                    <div><span class="label">Datum:</span><input type="text" name="date1"  size="25"/></div>
                    <div><span class="label"></span><input type="text" name="date2"  size="25"/></div>

                    <div class="submit">
                        <input type="submit" value="Search"> 
                    </div>
                </div>
            </div>
            </form>

When I use the action parameter in the form the servlet repondes like it should. But I can't seem to get the Ajax call to work.

What am I doing wrong?

Answer 1

you must add the success param to ajax function

$.ajax({
            type: "POST",
            url: "/ArchiveSearch/Search",
            dataType: "json",
            data: formData,
 success: function(data) {
    $('.result').html(data);
    alert('Load was performed.');
  }
});
