asp.net限时发送手机验证码

html代码

<p>
                        <strong>手机验证码：</strong> <asp:TextBox ID="code" runat="server" CssClass="box" style="width:90px" maxlength="4"></asp:TextBox> <input type="button" id="btncode" class="diarnu_net_btn" value="发送验证码" /> </p>

提交的时候只需验证Session["phoneCode"]和code.text的值就行

js代码

var secs=100;
$("#btncode").click(function(){
    var _phone='18000055568'; this.value=" 正在发送中 "; this.disabled=true; $.post("ajax.aspx",{type:"sendCode",phone:_phone},function(data){ if(data=="1") { //成功 for(var i=0;i<=secs;i++) { window.setTimeout("update(" + i + ")", i*1000); } }else{ alert("验证码发送失败，请检查手机是否输入有误！"); document.getElementById("btncode").value=" 发送验证码 "; document.getElementById("btncode").disabled=false; } }) }) function update(num) { if(num == secs) { document.getElementById("btncode").disabled=false; document.getElementById("btncode").click(); } else { printnr = secs-num; document.getElementById("btncode").value=" "+printnr+"秒后重发 "; } }
