User · Answer

The innerText property returns the actual text value of an html element while the innerHTML returns the HTML content  Example below    x000D   x000D  var element   document getElementById  hello    x000D  element innerText     lt strong gt  hello world  lt  strong gt    x000D  console log  The innerText property will not parse the html tags as html tags but as normal text  n    element innerText   x000D   x000D  console log  The innerHTML element property will encode the html tags found inside the text of the element  n    element innerHTML   x000D  element innerHTML     lt strong gt  hello world  lt  strong gt    x000D  console log  The  lt strong gt  tag we put above has been parsed using the innerHTML property so the  innerText will not show them  n     element innerText   x000D  console log element innerHTML   x000D   lt p id  hello  gt  Hello world  x000D   lt  p gt  x000D   x000D   x000D

Unlike innerText  though  innerHTML lets you work with HTML rich text and doesn t automatically encode and decode text  In other words  innerText retrieves and sets the content of the tag as plain text  whereas innerHTML retrieves and sets the content in HTML format
