javascript - jQuery - 表单仍然提交并返回 false

Question

http://jsfiddle.net/QsTfc/

由于某些奇怪的原因，即使我返回 false，表单仍会继续提交。我试过:

$("#submitEdit").submit(function() {
    return false;
});

$("#submitEdit").submit(function() {
    event.preventDefault();
});

这就是我目前拥有的:

<script>

$('a').click(function() {
    var parentId = $(this).closest('tr').attr('id');
    var child = $("#" + parentId).children().eq(1);
    var childText = $(child).text();
    $(child).html('<form action="<?php echo URL; ?>user/changeSettings/' + parentId + '" method="POST" id="submitEdit"><input type="text" name="' + parentId + '" value="' + childText + '" /></form>');
    console.log(childText);
});

$("#submitEdit").on("submit", function() {
    var url = $(this).attr('action');
    var data = $(this).serialize();
    alert(data);
    $.post(url, data, function(returned) {
        $(parentId + "Field").html(returned);
        return false;
    });
    return false;
});

</script>

根据您的 jsfiddle 演示，您的表单是动态添加的。所以，你必须使用委托(delegate):

$(document).on("submit", "#submitEdit", function() {
    var url = $(this).attr('action');
    var data = $(this).serialize();
    alert(data);
    $.post(url, data, function(returned) {
        $(parentId + "Field").html(returned);
        return false;
    });
    return false;
});
