jquery uses contains filters to implement exact matching methods _jquery

This article illustrates the way jquery uses contains filters to achieve exact matching. Share to everyone for your reference, specific as follows:

: The contains selector selects the element that contains the specified string.

The string can be text that is directly contained in an element, or is contained in a child element.

Often used with other elements/selectors to select elements in the specified group that contain the specified text, such as:

$ ("P:contains (IS)") indicates that all <p> elements that contain "is" are selected.

Another example:

$ ("P:contains (John)") or $ ("P:contains (" John) ") indicates that all <p> elements that contain" John "are selected.

Variables can also be used in the selector to achieve the purpose of the selection, such as:

$ (document). Ready (function () {
var ddd= "John";
$ ("div:contains (' + ddd + ')"). CSS ("Color", "#f00");

We can also use the jquery filter method and the contains method to achieve a more ambiguous match, such as:

$ (document). Ready (function () {
$ (". Box"). Filter (": Contains (Lee)"). CSS ("Color", "#f00");
});

Indicates that the text color of box containing "Lee" is set to red.

jquery uses contains filters to achieve exact matches:

<! DOCTYPE html>
