InnerText and innerHTML get the contents of the element. If the element contains only text, then innertext and innerHTML return the same value. However, if both text and other elements are included, InnerText will return only the representation of the text, and innerHTML will return all the elements and the HTML code of the text. The following table lists the different values that are returned based on the specific code innertext and innerHTML.

Code InnerText InnerHTML
<div>hello world</div> "Hello World" "Hello World"
<div><b>Hello</b>world</div> "Hello World" "<b>hello</b>world"
<div><span></span></div> "" "<span></span>"

Finally, by assigning the innertext to itself, it means removing all HTML tags from the specified element.
Odiv.innertext = Odiv.innertext;

InnerTextfunction Innertextdemo () {Test_id2.innertext="<i><b> Sets or gets the text that is within the start and end tags of the object .</b></i>"; }    //. outerHTMLfunction Outerhtmldemo () {test_id3.outerhtml="<i><b> Sets or gets the HTML form of the object and its contents .</b></i>"; }    //. Outertextfunction Outertextdemo () {Test_id4.outertext="<i><b> set (including tags) or get (excluding tags) the text of an object .</b></i>"; }    </script> 

Three, the difference:
The difference between innerHTML and outerHTML, innertext and Outertext is simply that:
1), innerHTML, and outerhtml the HTML that is included when setting the content of the object is parsed, and innertext and outertext do not.
2), when set, innerHTML and innertext only set the text within the label, while outerHTML and Outertext set the text including the label.

Special Note:
innerHTML is a standard-compliant attribute, and innertext only works with Internet Explorer, so use innerHTML as much as possible, and less innertext, if you want to output content that does not contain HTML tags, You can use innerHTML to get content that contains HTML tags, and then use regular expressions to remove HTML tags.
