  • 0

I am trying to run this function set_downloads($file[0]); when the download button is clicked, i can’t just add it in the code, as it will run. I can put it on a different page and do some sort of onclick event to load it, but i don’t know how to do this.

    <script type="text/javascript">
        var x = 0;
        var r = 0;
        function countdown() {
            if (x > 1) {
                x--;
                document.getElementById("button").innerHTML = x;
                r = setTimeout("countdown()",0);
            }
            else {
                clearTimeout(r);
                document.getElementById("button").innerHTML = "Click to download (<?php echo $filesize;?>) ";
                document.getElementById("button").disabled = "";
                document.getElementById("button").onclick = function() {
                    document.getElementById("button").disabled = "disabled";

                    document.getElementById("button").innerHTML = "Your download is starting..";

                };

            }
        }
        setTimeout("countdown()",1000);
    </script>
</head>
<body>
<label>
    <font size="5"></font>
</label>
<a href="http://IP/uploads/<?php echo $fullfile; ?>" >

    <button class="btn large orange" id="button" disabled="disabled">Click to download (<?php echo $filesize;?>) </button>

</a>

    $(document).ready(function(){
    var x = 0;
    var r = 0;
    function countdown() {
        if (x > 1) {
            x--;
            document.getElementById("button").innerHTML = x;
            r = setTimeout("countdown()",0);
        }
        else {
            clearTimeout(r);
            document.getElementById("button").innerHTML = "Click to download (<?php echo $filesize;?>) ";
            document.getElementById("button").disabled = "";
            document.getElementById("button").onclick = function() {
                document.getElementById("button").disabled = "disabled";

                document.getElementById("button").innerHTML = "Your download is starting..";

            };

        }
    }
    setTimeout("countdown()",1000);

     $('.btn').click(function(){
        set_downloads($file[0]);
     });
});

    This event handler is what you want to use to handle events. It uses a callback, which calls that function argument after the button is clicked.

    The other thing is, I’m not sure about your $file[0] variable, or where your set_downloads function is defined. where do you set these?
