Use and difference of HTML (), text (), Val () in jquery

There are 3 main ways to get object content in jquery, namely HTML (), text (), Val ().

Obj.html (): Gets all the HTML content of the object package, which is equivalent to innerHTML.

Obj.text (): Gets all the text content in the object, without the HTML tag. Generally used for Div, p, span, etc. without the value attribute of the element, equivalent to innertext.

Obj.val (): Gets the value of the object. Gets the value of the first element of a Selection object. Of course, this property is not limited to elements of value only, and is appropriate for form elements.

For example:

$ ("#source"). The result of HTML () is: Hello <textarea id= "text" >you,too</textarea>

$ ("#source"). The result of text () is: Hello You,too

$ ("#source"). The result of Val () is: ""

It can be seen that Val () obtains only the value of the object, and the div itself does not have a Value property, so its values are empty. Text () gets only plain text.
