            JS SSE callback isn't working with EventListener
            Asked 2021-Jan-26 at 09:28

            I'm using a JS library to stream server-sent-events on my html page:

            ANSWER

            Answered 2021-Jan-26 at 09:28

            When your script calls source.stream();, it is doing an XMLHttpRequest.send() operation, which is async by default.

            So, what is happening:

            1. user clicks, and post() is called
            2. SSE object and its event listener is set up
            3. source.stream() is called, which sends the request to the server.
            4. callback() (i.e. clip()) is called
            5. Server sends back a response
            6. Your message event handler is called
            7. textArea.value is set

            Luckily the fix is simple: you only want callback() to be called when a message is received. So move callback() to be at the end of the message event handler, not at the end of post().

            It will do this after every message event that is received. If you only wanted it to happen after the first event, you will need to implement some logic to keep track of how many events have been received. (And if there will only be one message event, you should be using an Ajax call, not an SSE/EventSource call.)

            UPDATE: Discussion in the comments are starting to get out of scope of your original question (where the answer is, simply put, "it is async, not sync"). But I think it is worth pointing out here that you set up a new SSE object every time the user clicks the button. Each SSE object will have its own dedicated TCP/IP socket and its own listener function. This is (generally) not a good idea: instead create the SSE connection once at the start of your web app.

            And, though your SSE polyfill library allows using POST, the standard SSE does not. If you only want the app to poll the server when the user presses the button, consider switching from using SSE to normal AJAX.

            Check if student is in right class and only show students that goes in the class that is pressed
            Asked 2020-Feb-19 at 12:43

            I have an assignnment where there is laid out a html script that shows radio buttons, saying the name of each class, and a json file that lists all the students names and which class they go too.

            I wondered is there a way to use addEventListener to do this? Because that's what I have heard is the right solution, and I have to do what the professor says.

            Sequelize association include returns null
            Asked 2017-Mar-30 at 08:43

            I am having an issue when I'm trying to associate a table into my query with sequelize-cli.

            My query works but it doesn't populate Adresse table. Only Patient is populated. Adresse array is ignored. (return null)

            I made a one-to-one relationship between the tables and am not sure if that's the cause of the error or if it is somewhere else where I am associating the two tables.

            Drag and Drop (Dragger event) prevents onclick
            Asked 2017-Feb-07 at 22:51

            we have used one jquery library called as jesse which works fine

            The thing is we have an li attributes and inside it we have used onclick event .. but somehow it stops working and we are unable to call onclick event .. Here is the fiddle for better understanding

            ...

            ANSWER

            Answered 2017-Feb-07 at 22:51

            The library doesn't use drag events. It listens to mousedown and if fired it stops default execution with e.preventDefault(); and watches over $(document).on('mousemove') and .on('mouseup').

            Therefore closing div can't hear any click event. You can slightly modify the library file to make it identify closing clicks.

            1. Add specific setting, say, closingClass to the class (line 7)
