1.禁用右键菜单 $(document).ready(function(){      $(document).bind("contextmenu",function(e){          return false;      }); }); 2.让字体闪烁 jQuery.fn.flash = function( color, duration ) {      var current = this.css( 'color' );      this.animate( { color: 'rgb(' + color + ')' }, duration / 2 );      this.animate( { color: current }, duration / 2 ); } $( '#someid' ).flash( '255,0,0', 1000 ); 3. 首先执行 $(function(){         //document is ready do something }); 4.检测browser // mozilla if (jQuery.browser.mozilla) {} // Safari if( $.browser.safari ) { //do something } //Above IE6 if ($.browser.msie && $.browser.version > 6 ) { //do something } // IE6 and below if ($.browser.msie && $.browser.version <= 6 ) { //do something } 5.检查存在的元素 if ($("#someDiv").length) {      //yes it does ,do something }
