checkJobName api always return an extra blank line in response body: " <div/>"
Change By: pan xu
Summary: checkJobName api always return Incomplete an extra blank line in response body: "  <div/>"
Attachment: jenkinsbug.png
on create job page, when typing in the job name text box, Jenkins call checkJobName api to check the item name, but this api always return an Incomplete extra blank line in response body :   "  <div/>" .

It caused the UI disable the submit button and I could never create a job. Please see the screenshot attached.

 

An example of the checkJobName api call and response:
Request URL:
 [ http://myjenkins.com/view/all/checkJobName?value=dfd ]

Re: checkJobName api always return an extra blank line in response body: " <div/>"

compare to another Jenkins server on Mac, the Difference between response body is: the linux server return an extra empty line before the "<div/>", please see the screenshot attached. I update the bug description

Re: checkJobName api always return an extra blank line in response body: " <div/>"

Hi,

from this screenshot I can't see if you selected any item (FreeStyle Project, Maven, Pipeline...) from the list.

When we first land on '/view/all/newJob' page no item category is selected (this is the key).

If we choose existing item name we won't be able to create new project which is ok, but if we choose non existing name we also won't be able to create new project because no item category is selected.

Preposition:

1) Add hover selector to OK button to provide user info to select item category.

Re: checkJobName api always return an extra blank line in response body: " <div/>"

Sorry for the late reply. " select an item" is not the key root cause for this issue.

See the latest attached screenshot please. I select an item category first, then type in the name text box. the submit button is still disabled.

The root cause is (in screenshot) the checkJobName api return an extra blank line in response.

Re: checkJobName api always return an extra blank line in response body: " <div/>"

This is a bug in the add-item.js on index.html.

The server sometimes will response with "\n</div>", and the page can't solve the situation and go to the error.

 

[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);
            }
          }
        });

The solve method：

''.charCodeAt(0)=NaN

modyfy /static/944f39f7/jsbundles/add-item.js

 

 

if (message !== '') {

Change to --->

if (message !== '' && Number.isNaN(message.charCodeAt(0))) {

After that, it will work OK.

Hope Jenkins could fix the problem quickly.
