ajax可以传送一个或多个参数到后台php中
<script> $(function(){ $("#sub_btn").click(function(){ var email = $("#email").val(); var preg = /^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*/; //匹配Email if(email=='' || !preg.test(email)){ alert("请填写正确的邮箱!"); }else{ $.ajax({ url:'xxx', type:'post', dataType:'json', data:{'email':email}, success:function(data,status){ alert(data.value); }, error:function(){ alert('error'); } }); } }); $('#submit_btn').click(function(){ var email = $("#email").val(); var key = $("#key").val(); var pwd = $("#pwd").val(); var confirm_pwd = $("#confirm_pwd").val(); var preg = /^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*/; //匹配Email var preg_pwd = /^[0-9a-zA-Z]{6,12}$/; var preg_key = /^[0-9]{6}$/; if(email=='' || !preg.test(email)){ alert("请填写正确的邮箱!"); return false; } if(key=='' || !preg_key.test(key)){ alert('请输入6位数字验证码'); return false; } if(pwd=='' || !preg_pwd.test(pwd)){ alert("请填写6到12位由字母和数字组成的密码,区分大小写"); return false; } if(confirm_pwd=='' || confirm_pwd != pwd){ alert('请输入正确的确认密码'); return false; }else{ $.ajax({ url:'xxx', type:'post', dataType:'json', data:{'email':email,'pwd':pwd,'key':key}, success:function(data,status){ alert(data.value); }, error:function(){ alert('error'); } }); } }); }) </script>
