我有一个空的元素,但是有空间来了,在java中检查这个的最佳方法是什么?
<element /> instead of <element/>
我已经尝试过检查if(element!=null)
和if(element is not empty)
但它对我不起作用
答案 0 :(得分:0)
使用字符串的力量
<div class="container">
<div class="left">
<p id="cagliari" class="rtejustify" style="text-align: left;">Text Text Text</p>
<iframe style="border: 0;" src="https://www.google.com/maps/embed?pb=!1m14!1m8!1m3!1d12364.675124477504!2d9.1242403!3d39.2163323!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x0%3A0xad759bffc1fbf334!2sItalSecurity+Agency+%7C+Agenzia+Investigativa!5e0!3m2!1sit!2sit!4v1469542451708" width="400" height="300" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div>
<div class="right">
<p id="oristano" class="rtejustify" style="text-align: left;">Text Text Text</p>
<iframe style="border: 0;" src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d3060.6645205664345!2d8.584972315150939!3d39.90414279457802!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x12dd9be3f40242ad%3A0x11a591da0ed6a074!2sItal%40Security+Agency!5e0!3m2!1sit!2sit!4v1469543170307" width="400" height="300" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div>
</div>
这消除了所有空格和不可见字符
