Data processing in jquery $. Data (),. Data (), $. hasdata () and $. removedata () Methods

We can use the data method to bind data to the DOM element, or delete it to determine whether it exists:

VaR$ P = $ ("p"), P = $ P [0]; $. Data (p,"Site", ""); $ P. append ($. hasdata (P)+ ""); // True $. removedata (p); $ P. append ($. hasdata (P)+ ""); // False

In HTML5, we use a large number of data-tag tags to quickly bind data to tags. In jquery, we also provide the corresponding method data () to help us quickly implement similar functions:

HTML: <Div ID="Site" Data-name=""></Div>

JS: Certificate ('{site'}.html ($ ('# site'). Data ("name "));
