I used the following technique to create a Modal Pop up on my SharePoint Page: https://jqueryui.com/dialog/#modal-form

It works create but when the Modal dialog screen appears, it refreshes on its own with out user input. By taking a look on the code, (I'm new so It could be staring me right in the phase), but I just don't see it.

I input everything in a CEWP but I received an error stating "Forms" and scripts are not alowed. So I just took the script and form portion and embedded it. But the Modal dialog still showed...it just refreshes by itself.

Here is the code from that page:

  <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
  <link rel="stylesheet" href="/resources/demos/style.css">
  <style>
    label, input { display:block; }
    input.text { margin-bottom:12px; width:95%; padding: .4em; }
    fieldset { padding:0; border:0; margin-top:25px; }
    h1 { font-size: 1.2em; margin: .6em 0; }
    div#users-contain { width: 350px; margin: 20px 0; }
    div#users-contain table { margin: 1em 0; border-collapse: collapse; width: 100%; }
    div#users-contain table td, div#users-contain table th { border: 1px solid #eee; padding: .6em 10px; text-align: left; }
    .ui-dialog .ui-state-error { padding: .3em; }
    .validateTips { border: 1px solid transparent; padding: 0.3em; }
  </style>

Try using your HTML like below:

<button type="button" id="create-user"> Create New User </button>
