A Z edited a comment on JENKINS-50330   Re: checkJobName api always return an extra blank line in response body: " <div/>" This is a bug, and I just find a way to modyfy add-item.js on index.html to fix it temporarily. The server sometimes will response with "\n</div>", and the page can't solve the situation and go to the error.   {code:java} [JenkinURL]/static/944f39f7/jsbundles/add-item.js     // Init NameField     $('input[name="name"]', '#createItem').on("blur input", function() {       if (!isItemNameEmpty()) {         var itemName = $('input[name="name"]', '#createItem').val();         $.get("checkJobName", { value: itemName }).done(function(data) {           var message = parseResponseFromCheckJobName(data);           //           BUG: When the checkJobName API response with "\n</div>", the message will be not '' ，message.charCodeAt(0)=10, message.lenth=1, then it will go to activateValidationMessage and will come out the above discussion situation.           if (message !== '') {             activateValidationMessage('#itemname-invalid', '.add-item-name', message);           } else {             cleanValidationMessages('.add-item-name');             showInputHelp('.add-item-name');             setFieldValidationStatus('name', true);             if (getFormValidationStatus()) {               enableSubmit(true);             }           }         }); {code} The solve method： ''.charCodeAt(0)=NaN modyfy /static/944f39f7/jsbundles/add-item.js     {code:java} if (message !== '') { Change to ---> if (message !== '' && Number.isNaN(message.charCodeAt(0))) {{code} After that, it will work OK. Hope Jenkins could fix the problem quickly.   Add Comment   This message was sent by Atlassian Jira (v7.13.6#713006-sha1:cc4451f) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
