jQuery tag contains content actions

Tags contain content operations

Use javascript operations:

• dvnode.innerHTML Get the information contained in the div

• dvnode.innerHTML = XXX; Set the content contained in the div

Note: innerHTML is not a w3c standard technology , many browsers only support it

Use jquery operation:

• ##$().html(); // Get the information contained in the node

• $().html(information); //Set the content contained in the node

• $().text (); //Get the "text string information" content contained in the node

• $().text(information); //Set the content contained in the node (if there is an html tag, just The "><" symbol becomes a symbol entity)

##The difference between html() and text() methods ：

##① Get content

The former can get html tags and ordinary string content

The latter only gets ordinary string content

② Set content

The former can set html tags and ordinary string content

The latter only sets ordinary string content. If there is tag tag content in the content, put the "< ;" ">" symbol is converted into a symbol entity<-----$lt; >----> Space------

The above two operations (get /Settings) If the operation content is pure string content, the effect will be the same.
