    <p>I have a form that is using the jQuery validate functionality, with some custom functions validating the values with ajax posts.</p> <p>My problem is when I submit the form, I have the submitHandler do ajax post to check if the field is valid by checking in the DB. I only want the form to submit if the value returned is valid.</p> <pre><code>(function ( $ ) { $.fn.checkValidSubDomain = function (params) { params['siteID'] = wlSiteID; var deferred = $.Deferred(); var promise = deferred.promise(); $("div#"+$(this).attr('id')+"Info").html(copyItems["info_checkingStatus"]); var jqxhr = $(this).ajaxPost('checkValidSubDomain', params) jqxhr.success(function (data){ if (data.validSubdomain) { $("div#"+$(this).attr('id')+"Info").html(copyItems["info_"+$(this).attr('id')+"Available"]); deferred.resolve(data); } else { $("div#"+$(this).attr('id')+"Info").html(copyItems["err_"+$(this).attr('id')+"Unavailable"]); deferred.reject(jqxhr, 'error'); } }) jqxhr.error(function (jqXHR, status, error){ $("div#"+$(this).attr('id')+"Info").html(copyItems["err_"+$(this).attr('id')+"Unavailable"]); deferred.reject(jqXHR, status, error); }); return promise; }; })(jQuery); var validationRules = { submitHandler: function(form) { var promise; if ($('input[name="domainSetting"]:checked').val() == 'subDomain') { alert("checking subdomain - " + $('#subDomainSiteName').val()) promise = $('#subDomainSiteName').checkValidSubDomain({'subDomain': $('#subDomainSiteName').val(), 'domain':$("#domainSelect option:selected").val()}); } promise.done(function() { form.submit(); }); return false; }, onfocusout: false, onkeyup: false, rules: { subDomainSiteName: { required: { depends: '#domainSettingSubDomain:checked' } } } }; $('#domainSettingsFRM').formValidation(validationRules); </code></pre> <p>I'm not sure how I get to the form to only submit if the field is valid. Currently, it's just showing the alert and then submitting the form regardless of the value.</p> <p>Any help appreciated</p> <p><strong>EDIT</strong></p> <p>I think I just figured it out. Once the async ajax call is finished, the promise.done() will trigger. At that point I simply check the state to see if it is resolved or rejected. Changing the code to the following seems to do the trick.</p> <pre><code>promise.done(function() { if (promise.state() == "resolved") { form.submit(); } }); </code></pre>

    1. CO`$(this).attr('id')`? You can simply use `this.id`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
