Question

我遇到了$.post命令的奇怪行为。我有一个$.post(param,returned data)的AJAX请求，它将图片加载到访问者的页面上。

这是代码，带有一点动画：

function showPicturesByCat(cat){
$('.local-overlay').fadeIn(200);
$('#picturesByCat').stop().animate({height: '0px' },200);
setTimeout(function(){
    $.post('./ajax/populate.php',{operation:'show-pictures-on-front',cat:cat})
        .done(function(data){
            $('#picturesByCat').html(data);
            setTimeout(function(){
                var inaltime = $('#picturesByCat')[0].scrollHeight+20;
                $('#picturesByCat').stop().animate({height: inaltime+'px' },500);
                $('#picturesByCat').css({opacity: 1});
                $('.local-overlay').delay(500).fadeOut(300);
            },300);
            $('html, body').delay(200).stop().animate({
                scrollTop: $('#picturesByCat').offset().top
            },300);
        });
},200);
}

在PHP方面，根据所选类别（cat），它只是在数据库中加载带有名称的图片。代码在PC上完美运行......但是当它转向移动时，Chrome和Firefox都会做同样的事情。当我选择一个类别时，图片加载但不完全。如果你滚动到底部，你会看到这个东西。如果我在同一类别上第二次点击，则图片会完全加载。

我无法弄清楚这一点，对我来说太奇怪了。也许你们中的一些人可以发现或已经知道它的错误。

这是转储数据，如评论中所要求的那样。

希望它有所帮助，虽然我看不出任何错误。

问题不是来自$ .post。问题是由以下原因引起的：

private void showListPopupWindow(View anchor) {
    List<ListPopupItem> listPopupItems = new ArrayList<>();
    listPopupItems.add(new ListPopupItem("Menu 1", R.mipmap.ic_launcher));
    listPopupItems.add(new ListPopupItem("Menu 2", R.mipmap.ic_launcher));
    listPopupItems.add(new ListPopupItem("Menu 3", R.mipmap.ic_launcher));

    final ListPopupWindow listPopupWindow =
            createListPopupWindow(anchor, ViewGroup.LayoutParams.MATCH_PARENT, listPopupItems);
    listPopupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            listPopupWindow.dismiss();
            Toast.makeText(MainActivity.this, "clicked at " + position, Toast.LENGTH_SHORT)
                    .show();
        }
    });
    listPopupWindow.show();
}

private ListPopupWindow createListPopupWindow(View anchor, int width,
        List<ListPopupItem> items) {
    final ListPopupWindow popup = new ListPopupWindow(this);
    ListAdapter adapter = new ListPopupWindowAdapter(items);
    popup.setAnchorView(anchor);
    popup.setWidth(width);
    popup.setAdapter(adapter);
    return popup;
}

<强>原因：

由于未正确计算高度，因为当图像开始加载时，其高度计算不正确，那么#picturesByCat仅限于错误的计算值，因此未完全显示，但图像正确加载。

第二次单击该类别时，这些图像会完全显示并且高度正确，然后问题就消失了。

解决：

动画结束后将高度设置为自动：

button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { showListPopupWindow(view); } });

jQuery $ .post返回不完整的数据
