$('img.product_image').attr('src').change(function() {
    alert($('img.product_image').attr('src'));
});

嗨,你好

我正在尝试编写一些代码,当src更改时会提醒img.product_image,但是当我运行我的页面并单击按钮更改图像src时,警报不会出现...我的语法错了吗？

这是图像:

<img class="product_image colorbox-1160" id="product_image_1160" alt="Black Onyx Ring" title="Black Onyx Ring" src="https://www.taranmarlowjewelry.com/wp-content/uploads/2012/10/Black-Onyx-Ring.jpg" width="400">

当我点击其中一个缩略图时,图像src会改变:

<div class="wpcart_gallery" style="text-align:center; padding-top:5px;">

        <img width="50" …

如何将Spinner"箭头"0dp 对齐到当前所选Spinner项目的右侧？

默认情况下,Spinner查找最长string,并将其放在右侧.那么,我如何找到当前的string并将其置于右侧？

我用来实现的代码Spinner:

ArrayAdapter<CharSequence> spinnerAdapter =
            ArrayAdapter.createFromResource(getSupportActionBar().getThemedContext(),
                    R.array.main_navigation_list, R.layout.spinner_text);

spinnerAdapter.setDropDownViewResource(R.layout.spinner_item);

mNavigationSpinner = new Spinner(getSupportActionBar().getThemedContext());
mNavigationSpinner.setAdapter(spinnerAdapter);

mNavigationSpinner.setOnItemSelectedListener(this);
toolbar.addView(mNavigationSpinner);

有任何想法帮助!谢谢

这个问题是一个从未回答过的重复问题. 根据显示的标题长度动态定位ActionBar Spinner的右上角箭头
