Baidu rich text Ueditor will issue additional tags

We write text using ueditor back sometimes this is the label, but directly into the text is written to the input box, and each submission will append a tag

This is because you save the database text tag is escaped, such as: & lt; p & gt; & amp; nbsp; & amp; nbsp; & amp; nbsp; & amp; nbsp; & amp; nbsp; & amp; nbsp; & amp; nbsp; & amp; nbsp ;,

The escape character through ueditor.all.js will convert directly into setContent the label when the text is written back to the input box, and each time setContent will write back to you automatically add a label p, then we

To advance to escape the label, so ueditor write back when he thought it was a label, rather than escaping to a text written back to the input box, when you have returned from the label ueditor will not add p tags
