Three methods of html Tag output after reading data from the database, three methods of tag

Maybe the data read by many people from the database does not need to be converted into html tags, but one day you may find that when we need to output html tags, the compiler will automatically help us output them as strings. This is what we can do.

Method 1:

The most common method is to use JS or JQ.

JQ:

$ ("# Div" ).html ("<span> I am an HTML code </span> ");

JS:

Var dobj = document. getElementById ("div"); dobj. innerHTML = "<span> I am an HTML code </span> ";

Method 2:

When you find that the data read from the database is not running in the above two methods, you can try it.

$ ("# Div" ).html ("@ Html. Raw (I am the HTML code in the database )");
