每个jQuery开发人员必须知道的5个小技巧
jQuery是个非常优秀的框架。
下面是5个小技巧
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
- }
