Forbidding creating issues until an attachment is added

Problem

We want to hide the create issue button until at least one attachment is added.

Solution

We will use lfExecuteJS in order to watch the attachments module from the create screen and, according to its files, to hide or show the create issue button.

All you will have to do is to add in our main live fields script a line like the one below:

livefields.sil

lfExecuteJS("lf.js");

Secondly, we will create the "lf.js" file in the silprograms directory. It's content should be:

lf.js

var attachments = AJS.$(".file-input-list ");
console.log("Got attachments");
AJS.$(function() {
  var $div = attachments;
  var html = $div.html();
  var checking = setInterval(function() {
    var newhtml = $div.html();
    if (html != newhtml) {
      myCallback();
      html = newhtml;
    }
  },100);
  function myCallback() {
    console.log("Content changed");
    var size = AJS.$("[duitype='dndattachment/progressbars/ProjectUploadProgressBar']").size();
    if (size == 0) {
        console.log("You can't create such an issue");
         AJS.$("#create-issue-submit").hide();
         AJS.$("#issue-create-submit").hide();
    } else {
        console.log("You can now create the issue");
        AJS.$("#create-issue-submit").show();
        AJS.$("#issue-create-submit").show();
    }
  }
});
