  • Attribute Equals Selector [name=”value”]

    Attribute Equals Selector [name=”value”]

    attributeEquals selector

    Description: Selects elements that have the specified attribute with a value exactly equal to a certain value.

    • version added: 1.0jQuery( "[attribute='value']" )

      attribute: An attribute name.

      value: An attribute value. Can be either a valid identifier or a quoted string.

    Attribute Contains Selector [name*=”value”]

    attributeContains selector

    Description: Selects elements that have the specified attribute with a value containing a given substring.

    • version added: 1.0jQuery( "[attribute*='value']" )

      attribute: An attribute name.

      value: An attribute value. Can be either a valid identifier or a quoted string.

    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
