jquery扩展,select控件,enter,focus,jquery扩展select本文实例讲述了jquery通过扩展select控件实现支持enter或focus选择的方法。分享给大家供大家参考，具体如下： /**************************************** @ author jdkleo* @ date 2013/2/27 JQuery SelKeysUSAGE: jQuery.selkeys.enter(jQuery("#selcon")); jQuery.selkeys.focus(jQuery("#selcon2"));*****************************************/(function (jQuery){ this.version = '(beta)(0.0.1)'; this.all = {}; /**---------enter---------**/ this.enter = function(sel){ var flag = 1; var open = function(){ if(flag==1){ sel.get(0).size = sel.get(0).options.length; flag=0; }else{ sel.get(0).size = 1; flag=1; } }; sel.keydown(function(e){ e = e ? e :(window.event ? window.event : null); var code = e.keyCode || e.which || e.charCode; if(code == 13) { open(); return false; } }); sel.blur(function(){ sel.get(0).size=1; flag=1; }); } /**---------focus---------**/ this.focus = function(sel){ var flag = 1; var open = function(){ if(flag==1){ sel.get(0).size = sel.get(0).options.length; flag=0; }else{ sel.get(0).size = 1; flag=1; } }; sel.focus(function(){ open(); return false; }); sel.blur(function(){ sel.get(0).size=1; flag=1; }); sel.keydown(function(e){ e = e ? e :(window.event ? window.event : null); var code = e.keyCode || e.which || e.charCode; if(code == 13) { sel.get(0).size=1; flag=1; return false; } }); } /**---------all---------**/ jQuery.selkeys = this; return jQuery; })(jQuery);希望本文所述对大家jQuery程序设计有所帮助。
