jQuery的toggle()方法应该是在鼠标点击后才会触发,现在的问题是在ready加载后就自动触发了,怎么回事呢?
答案是jQuery的版本问题,在1.9以后的版本toggle()就存在这个问题,用之前的版本就正常了。?
如果你非常喜欢这个功能,有2个办法,一个办法是jquery官网提供的一个版本升级文件。http://blog.jquery.com/2013/05/08/jquery-migrate-1-2-1-released/
另外一个办法是笨办法,就是把原来的那块代码拿出来,写成一个插件。
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>test</title> <script type="text/javascript" src="http://cdn.staticfile.org/jquery/1.11.1/jquery.js"></script> </head> <body> <button>test click me</button> <script> $(document).ready(function(){ $("button").toggle(function(){ $("body").css("background-color", "green"); }, function(){ $("body").css("background-color", "red"); }, function(){ $("body").css("background-color", "yellow"); }); }); $.fn.toggle = function( fn ) { // Save reference to arguments for access in closure var args = arguments, guid = fn.guid || jQuery.guid++, i = 0, toggler = function( event ) { // Figure out which function to execute var lastToggle = ( jQuery._data( this, "lastToggle" + fn.guid ) || 0 ) % i; jQuery._data( this, "lastToggle" + fn.guid, lastToggle + 1 ); // Make sure that clicks stop event.preventDefault(); // and execute the function return args[ lastToggle ].apply( this, arguments ) || false; }; // link all the functions, so any of them can unbind this click handler toggler.guid = guid; while ( i < args.length ) { args[ i++ ].guid = guid; } return this.click( toggler ); } </script> </body> </html>
