使用Apache PDFBox将实心圆圈添加到PDF页面(Adding of filled circles to PDF page using Apache PDFBox)

 我看到几个问题.. 
 
 如果使用表单助手 （ Form::open() / Form::close() ），则无需手动包含隐藏的CSRF令牌元素。 然而，更大的问题是你的javascript： 
 
$('.profile-image .delete a.delete').click(function() {
    $(this).parent().find('.deletepic').click();
});

$.('form[name=delete-profile-image]')({
    url: $('form[name=update-account]').data('image-delete'),
    type: 'POST',
    dataType: 'json'
});
 
 AJAX呼叫在哪里？ （提示，它只是不存在..）当你可以在锚点本身触发AJAX调用时，为什么你会有一个锚元素触发单击表单内的隐藏按钮？ 尝试将HTML更改为类似的内容...... 
 
@if (!empty($image))
    <a href="#" class="delete">Delete</a>
    {{ Form::open(array('url' => route('customer.account.profile.image.delete'), 'style' => 'display: none', 'id' => 'image_delete')) }}
        {{ Form::text('image', $image) }}
    {{ Form::close() }}
@endif
 
 并将您的javascript更新为以下内容： 
 
$('.profile-image .delete a.delete').click(function() {
    $('#image_delete').submit()
});

Couple of issues I see..
 
If you use the form helpers ( Form::open() / Form::close() ) you won't need to include the hidden CSRF token element manually. However the bigger issue is your javascript:
 
$('.profile-image .delete a.delete').click(function() {
    $(this).parent().find('.deletepic').click();
});

$.('form[name=delete-profile-image]')({
    url: $('form[name=update-account]').data('image-delete'),
    type: 'POST',
    dataType: 'json'
});
 
Where is the AJAX call? (Hint, it's just not there..) Why would you have an anchor element trigger a click on a hidden button inside a form when you can just fire off the AJAX call on the anchor itself? Try changing your HTML to something like this...
 
@if (!empty($image))
    <a href="#" class="delete">Delete</a>
    {{ Form::open(array('url' => route('customer.account.profile.image.delete'), 'style' => 'display: none', 'id' => 'image_delete')) }}
        {{ Form::text('image', $image) }}
    {{ Form::close() }}
@endif
 
And update your javascript to something like this:
 
$('.profile-image .delete a.delete').click(function() {
    $('#image_delete').submit()
});
