Js实现手机发送验证码时按钮延迟操作

实例代码记录：

<script type="text/javascript"> function start_sms_button(obj){var count = 1 ;var sum = 30;var i = setInterval(function(){if(count > 10){obj.attr('disabled',false);obj.val('发送验证码');clearInterval(i);}else{obj.val('剩余'+parseInt(sum - count)+'秒');}count++;},1000); }$(function(){//发送验证码$('#send_sms').click(function(){var phone_obj = $('input[name="phone"]');var send_obj = $('input#send_sms');var val = phone_obj.val();if(val){if(IsMobile(val)){send_obj.attr('disabled',"disabled");//30秒后重新启动发送按钮start_sms_button(send_obj);$.ajax({url:'{#url_reset("index/sms")#}',data:{'mobile':val},dataType:'json',type:'post',beforeSend:function(){show_loading_body();},complete:function(){show_loading_body();},success:function(data){if(data.status!=undefined && (data.status == 'ok' || data.status == 'error')){showMsg(data.msg);}}});}else{showMsg("手机号的格式错误");}}else{showMsg('手机号不能为空');}}); });</script>
