标签: jquery html

我有两个 h1标签,其内容为标题第二标题

我的问题是使用jquery both the h1 tags get activated时。

want the Second heading only to be used in jquery。我该如何实现?

 function animateText() {
            TweenMax.from($('h1'), 0.8, {
                scale: 0.4,
                opacity: 0,
                rotation: 15,
                ease: Back.easeOut.config(4),
            });
        }
<h1 >Heading</h1>

<h1 >second heading</h1>

您可以将id标签添加到元素:

<h1 id="not_using">Heading</h1>

<h1 id="use_this_one">second heading</h1>

然后通过其ID识别它们。

使用:contains selector

TweenMax.from($('h1:contains(Second)')//...

在这种情况下,您也可以使用adjacent sibling combinator

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
 if (requestCode == REQUEST_CONTACT && data?.data != null) {
               val contactUri = data.data;
        val crContacts = contentResolver.query(contactUri, null, null, null, null);
        crContacts.moveToFirst()
        val id = crContacts.getString(crContacts.getColumnIndex(ContactsContract.Contacts._ID));
        if (Integer.parseInt(crContacts.getString(crContacts.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
            val crPhones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                            + " = ?", arrayOf(id), null)
            crPhones.moveToFirst()
        var phoneNo = crPhones.getString(
crPhones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))                     
                crPhones.close()
            }
            crContacts.close()
            }
    }
function animateText() {
            TweenMax.from($('h1 + h1'), 0.8, {
                scale: 0.4,
                opacity: 0,
                rotation: 15,
                ease: Back.easeOut.config(4),
            });
        }
        
animateText();

如果您不想在第二个 h1 标记中使用任何ID,请按照以下说明使用 :eq() Selector

 function animateText() {
        TweenMax.from( $('h1:eq(1)'), 0.8, { //You can also use $('h1').eq(1)
            scale: 0.4,
            opacity: 0,
            rotation: 15,
            ease: Back.easeOut.config(4),
        });
    }
