This is the most generous of the jQuery attribute selectors that match against a value. It will select an element if the selector's string appears anywhere within the element's attribute value. Compare this selector with the Attribute Contains Word selector (e.g. [attr~="word"]), which is more appropriate in many cases.
Example:
Finds all inputs with a name attribute that contains 'man' and sets the value with some text.
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>attributeContains demo</title> <script src="https://code.jquery.com/jquery-3.5.0.js"></script> </head> <body> <input name="man-news"> <input name="milkman"> <input name="letterman2"> <input name="newmilk"> <script> $( "input[name*='man']" ).val( "has man in it!" ); </script> </body> </html>
只有前面三个input里面会有字符串"has man in it"，第四个是没有的
