JSP failed to submit solution for content in Nicedit _jsp programming

In Google's process to see this article ("Nicedit in jquery can not get the textarea value") to get an inspiration, that is, you can read out the Nicedit Rich Text editor with JS content, assign its contents to textarea, and then submit the form. The code is:

Copy Code code as follows:

<textarea name= "Intro" rows= "cols=" "id=" Introcontent "style=" width:750px; height:300px; border:1px solid #000; " >${sightInfo.introduction}</textarea>
<input type= "button" value= "commits" onclick= "$ (' #introContent '). Val ($ ('. Nicedit-main '). html ()), $ (' form '). Submit (); />

$ (' #introContent '). Val ($ ('. Nicedit-main '). html ());

This code can ensure that the contents of the Nicedit are assigned to the TEXTAREA element before the form is submitted. This will not be empty if the value of "Intro" is read in the servlet.
