JavaScript 阻止表单提交

当我按下 JavaScript 对话框上的取消按钮时，我试图让我的表单不提交。

我有这个代码：

  $(document).ready(function() {
    $("#submit").click(function (e) {
        e.preventDefault();
        var link = $(this).attr("href"); // "get" the intended link in a var
        var result = confirm("Are you sure you want to log this fault?");
        if (result) {
            document.location.href = link;  // if result, "set" the document location      
        }
    });
});

无论我是否按“确定”或“取消”按钮，表单都会提交，即使我有阻止默认代码。

我的 HTML 代码是：

<button type="submit" id="submit" class="btn btn-default"><span class="glyphicon glyphicon-floppy-save"></span></button>

<form id="myform" method="post" action="/the/post/url">

<!-- other elements -->
....
....
....

<button type="submit" id="submit" class="btn btn-default">
    <span class="glyphicon glyphicon-floppy-save"></span>
</button>

</form>

$(function() {
    //this would do the same as button click as both submit the form
    $(document).on("submit", "#myform", function (e) {
        var result = confirm("Are you sure you want to log this fault?");
        //if cancel is cliked
        if (!result) {
             return false;      
        }
        //if ok is cliked, form will be submitted
    });
});
