JQuery是个不错的框架,以下总结了5个每个网站开发者都应该知道的小技巧:
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.准备文档替换方案
$(function(){ //document is ready do something });
4.检测browser
// Safari if( $.browser.safari ) { //do something } //Above IE6 if ($.browser.msie && $.browser.version > 6 ) { //do something } // IE6 and below if ($.browser.msie && $.browser.version <= 6 ) { //do something } // Firefox 2 and above if ($.browser.mozilla && $.browser.version >= "1.8" ) { //do something }
5.检查存在的元素
if ($("#someDiv").length) { //yes it does ,do something }
