Jquery () text () Usage

. Text () is used to read the plain text content of an element, including its child element.

It is easy to get the content in tag a, just locate it:
$ (". Demo p a"). text ();

However, it is difficult to get p's text, and it cannot be done in one place.
$ P = $ (". demo p"). clone ();
$ P. children (). remove (). end (). text ();

How does jQuery obtain the text content of an element, such as this simple example?

First, your var x = document. getElementsByTagName ("p"); after this statement is executed, x is a dom array instead of a jquery object. Y references an element in the dom array. You can obtain the text value by obtaining the value of y. innerHTML.
Test:
$ (Document). ready (function (){
Var x = document. getElementsByTagName ("p ");
Var y = x [0];
Alert (y. innerHTML); // obtain the text in the first p element tag
});
