copied!<p>user1502890,</p> <h2>Server-side</h2> <p>I don't really know C# but it appears that you are trying to build a JSON string directly. It is far more normal (and easier and more reliable) to build an object and then to stringify it into JSON with either a built-in language command or a utility method. I guess this must be possible in C#.</p> <h2>Client-side</h2> <p>Assuming the credentials fields to be in a form with <code>id="credentialsForm"</code> and the server-side script to be requestable as the relative URL "myCredentialsChecker.xtn", then the jQuery will be something like this:</p> <pre><code>$(function() { function loginResponse(j) { j = j || {}; if (j.LoginSuccess) { //... } else { $('#txtUserName').attr("class", j.txtUserName ? j.txtUserName : "Input"); $('#txtPassword').attr("class", j.txtPassword ? j.txtPassword : "Input"); $('#txtTestTokenNumber1').attr("class", j.txtTestTokenNumber1 ? j.txtTestTokenNumber1 : "Error"); $('#txtTestTokenNumber2').attr("class", j.txtTestTokenNumber2 ? j.txtTestTokenNumber2 : "Error"); $('#txtTestTokenNumber3').attr("class", j.txtTestTokenNumber3 ? j.txtTestTokenNumber3 : "Error"); $('#txtTestTokenNumber4').attr("class", j.txtTestTokenNumber4 ? j.txtTestTokenNumber4 : "Error"); $('#ErrorControl').html(''); } } $("#credentialsForm").on('submit', function() { $.ajax({ url: "myCredentialsChecker.xxx", data: $(this).serialize(), type: 'POST', // or 'GET' dataType: 'json', success: function(j) { loginResponse(j); ), error: function() { loginResponse(); } }); return false; }); }); </code></pre> <p><strong>Notes</strong></p> <ul> <li><p>Everything in the <code>else{...}</code> clause simplifies as above because <code>''</code> and <code>undefined</code> are both falsy, so simply testing <code>foo</code> will do the job. The ternary alternaive to <code>if(){...} else{...}</code> also makes for compact code.</p></li> <li><p>I'm not convinced that setting classes to the returned strings is the right thing to do but I've not changed this aspect.</p></li> </ul>
