copied!<p>Your code <em>as quoted</em> is fine (I've tried it locally).</p> <p>My guess is that the <code>formParams</code> string in your question is just an example, and in reality you're doing something to generate that string on the fly, and the problem lies in <em>that</em> code instead.</p> <p>For instance, are you sure you're escaping characters correctly (using <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/encodeURIComponent" rel="nofollow"><code>encodeURIComponent</code></a>)? Or better yet, let jQuery deal with it, like this:</p> <pre><code>$.ajax({ type: 'POST', url: '/foo.jsp', async: false, data: { fe1: $("#somefield1").val(), fe2: $("#somefield2").val(), fe3: $("#somefield3").val() }, complete: function(xmlRequestObject, successString){ ymmReceiveAjaxResponse(xmlRequestObject, successString); } }); </code></pre> <p>If you pass in an object, jQuery will handle the URI-encoding for you. If you <em>really</em> want to do it yourself:</p> <pre><code>var formParams = "fe1=" + encodeURIComponent($("#somefield1").val()) + "fe2=" + encodeURIComponent($("#somefield2").val()) + "fe3=" + encodeURIComponent($("#somefield3").val()); $.ajax({ type: 'POST', url: '/foo.jsp', async: false, data: formParams, complete: function(xmlRequestObject, successString){ ymmReceiveAjaxResponse(xmlRequestObject, successString); } }); </code></pre> <p>There I haven't encoded the field names because those names don't have any special chars in them; you need to if your form names are more interesting than that.</p>
