simple way (same as "$(document).ready(function(){"):
1 2 3 4 5 6 7 8 9 | <script> $( function (){ $( '.target' ).css( 'background-color' , 'yellow' ); }); </script> |
same as previous but with preventing $-conflicts with other js-frameworks:
1 2 3 4 5 6 7 8 9 | <script> jQuery( function ($){ $( '.target' ).css( 'background-color' , 'yellow' ); }); </script> |
window-load (use this method when you need to manipulate with images; only in this way you can get the height of the images with js in chrome which are not yet loaded for example):
1 2 3 4 5 6 7 8 9 | <script> $(window).load( function () { $( '.target' ).css( 'background-color' , 'yellow' ); }); </script> |
Finding elements:
1 2 3 4 5 6 7 8 9 | <script> jQuery( '.target' , this ); // finding all target elements inside of the current element jQuery( this ).find( '.target' ); // same as previous jQuery( this ).children( '.target' ); // can be used if the target elements are direct descendants of the current element </script> |
jQuery selectors:
1 2 3 4 5 | <script> $( '.target, .target2' ).css( 'background-color' , 'yellow' ); </script> |
Creating html tags with jQuery:
1 2 3 4 5 6 7 8 9 10 11 | <script> $( '<blockquote></blockquote>' , { class : 'quote' , text: $( '.qq' ).text() }).prependTo( $( '.target' ) ); </script> |
Move elements with jQuery:
1 2 3 4 5 6 7 | <script> $( 'h1' ).appendTo( $( '.target' ) ); $( 'h2' ).after( $( '.target' ) ); // or this way </script> |
