我的 Facebook 注册社交插件有以下代码:
<iframe src="https://www.facebook.com/plugins/registration?
client_id=xxxxxxxxxxxxxxxx&
redirect_uri=http://www.pingxxxxxx.com/facebook_registration_plugin/fbwe/trial.php&
fields=[
{'name':'name'},
{'name':'email'},
{'name':'location'},
{'name':'gender'},
{'name':'birthday'},
{'name':'about', 'description':'About Youtself', 'type':'text'},
]"
scrolling="auto"
frameborder="no"
style="border:none"
allowTransparency="true"
width="100%"
height="330">
</iframe>
我想让最后一个字段,即“关于”对用户来说是可选的。这个领域
{'name':'about', 'description':'About Youtself', 'type':'text'},
谁能告诉我如何做到这一点?
