js 代碼

<script>

layui.use(['form', 'layedit', 'laydate','jquery'], function() {
    var form = layui.form,
        $ = layui.jquery,
        layer = layui.layer;
    //監聽提交
    form.on('submit(form_commit)', function(data) {

        
        $.ajax({
            url: "/admin/data_add_send",
            data: data.field,
            type: 'post',
            async: false,
            success: function(data) {
                if (data.status == 2) {
                    layer.msg(data.message, {
                        icon: 1,
                        time: 1000
                    }, function() {
                        parent.location.reload();
                    });
                } else {
                    layer.msg(data.message);
                }
            }
        })
        return false;
    });
});
</script>

解決方案：
js form提交 上邊 加一句 form render()
完整代碼

<script>

layui.use(['form', 'layedit', 'laydate','jquery'], function() {
    var form = layui.form,
        $ = layui.jquery,
        layer = layui.layer;
    form.render();
    //監聽提交
    form.on('submit(form_commit)', function(data) {

        $.ajax({
            url: "/admin/data_add_send",
            data: data.field,
            type: 'post',
            async: false,
            success: function(data) {
                if (data.status == 2) {
                    layer.msg(data.message, {
                        icon: 1,
                        time: 1000

                    });
                } else {
                    layer.msg(data.message);
                }
