javascript - 如何实现ladda-bootstrap按钮加载动画？

Question

这是 github 文档:https://github.com/msurguy/ladda-bootstrap

我试图让我的代码工作，但由于某种原因，ladda 不会停止旋转(按钮永远不会再次启用)，即使我放置“Ladda.stopAll();” AJAX 调用之后。这是我的代码:

<button type="button" class="btn btn-lg btn-success ladda-button" data-style="expand-left" id="genPDF"><span class="ladda-label">Generate PDF</span></button>

<script>

    Ladda.bind('button[id=genPDF]');

    $('#genPDF').click(function () {

        //Another approach I tried
        //Ladda.bind(this);

        var str = "tmName=" + $("#tmName").val() +
            "&headingText=" + $("#headingText").val();

        $.ajax({
            url: "testing.php",
            data: str,
            cache: false,
            success: function (data) {
                //None of this code matters, it all works fine
                console.log(data);
                var container = document.getElementById("pdfContainer");
                var content = container.innerHTML;
                container.innerHTML = content;
            }
        });

        //If I placed Ladda.stopAll(); here, the ladda wouldn't even
        //START spinning upon being clicked on.
    });

</script>

用这个就可以了

$('#yourladda_btn').click(function(){
    var l = Ladda.create(this);
    l.start();
    $.ajax({
        url: 'test.php',
        type: "post",
        data: {"yourdata":"test"},
        success: function(){

        }

    }).always(
            function() {
                l.stop();
            }
    );
});
