现在都用h5表单进行验证了，以下方式仅做回忆

debug: true, //调试模式取消submit的默认提交功能
//errorClass: "label.error", //默认为错误的样式类为：error
focusInvalid: false, //当为false时，验证无效时，没有焦点响应
onkeyup: false,
submitHandler: function(form){ //表单提交句柄,为一回调函数，带一个参数：form
alert("提交表单");
form.submit(); //提交表单
},
}); }); </script> </head>
html:
<body>
<form id="myform" method="post" action="">
<p>
<label for="myname">用户名：</label>
<!-- id和name最好同时写上 -->
<input id="myname" name="myname" />
</p>
<p>
<label for="email">E-Mail：</label>
<input id="email" name="email" />
</p>
<p>
<label for="password">登陆密码：</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">确认密码：</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<input class="submit" type="submit" value="立即注册" />
</p>
</form>
</body>
</html>
自定义验证：
$.validator.addMethod(
"zidingyi", //验证方法名称
function(value, element, param){ //验证规则
var reg=new RegExp(/(^[1-9]\d{5}(18|19|([23]\d))\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$)|(^[1-9]\d{5}\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{2}[0-9Xx]$)/);
if(!reg.test(value)){
return false;
}
return true;
},
'请填写正确的身份证号'//验证提示信息
);
调用方法：
//input验证
$("#form-article-add").validate({
rules: {
p_name: {
required: true,
},
jm_name: {
required: true,
},
real_name:{
required:true,
maxlength:12,
},
grade:{
required:true,
},
id_card:{
zidingyi1:true,
required:true,
},
自己开发功能：
$(function(){
//input验证
$("#form-article-add").validate({
rules:{
sort:{
required:true,
min:1,
max:999,
digits:true,
},
num:{
required:true,
min:1,
max:999,
digits:true,
},
price:{
required:true,
decimalpoint:true,
},
reference:{
required:true,
min:1,
max:99999
},
starttime:{
required:true,
date:true,
},
endtime:{
required:true,
date:true,
},
},
messages: {
},
onkeyup:true,
debug:true, //debug模式，开启时submitHandler出错也不会跳转页面
/*保存并提交时执行的事件*/
submitHandler:function(){
var ti=document.getElementById('input_img');
/*if (!ti.files || !ti.files[0]) {
return layer.msg('必须选择详情图');
}*/
if (!ti.files || !ti.files[0]) {
if(filetype) {
ti.files = filetype;
if(!ti.files) {
return layer.msg('必须选择详情图');
}
}else{
return layer.msg('必须选择详情图');
}
}
var tii=document.getElementById('input_hxi');
/*if (!ti.files || !ti.files[0]) {
return layer.msg('必须选择历史小图');
}*/
if (!tii.files || !tii.files[0]) {
if(historyimg) {
tii.files = historyimg;
if(!tii.files) {
return layer.msg('必须选择历史小图');
}
}else{
return layer.msg('必须选择历史小图');
}
}
//判断基准为小数后两位
var referenceid=document.getElementById("reference").value;
var reg = /^\d+(\.\d{1,2})?$/;
var isfloat = reg.test(referenceid);//console.log(isfloat);
if (referenceid%1 !== 0 && !isfloat){
$("#reference").focus();
return layer.msg('小数后面只能写两位');
}
var titles=document.getElementById('title').value;
if(/[~!@#$^&*()=|{}':;',\[\].<>/?~！@#￥……&*（）——+|{}【】‘；：”“'。，、？]/.test(titles))
{
return layer.msg('标题不能含有非法字符');
}
if (titles.length>15) {
return layer.msg('标题必须小于15个字符');
}
var pd=false;
layer.confirm('确认添加业绩活动?',function() {
if (pd) {
return;
}
pd = true;
layer.load(0,{
shade:[0.5,'#fff'],
zindex:1
});
var formData = new FormData();
formData.append("file0",$("#input_img")[0].files[0]);
formData.append("file1",$("#input_hxi")[0].files[0]);
formData.append("public_key",'<?php echo C('imgparam')['public_key']; ?>');
formData.append("type",6);
$.ajax({
url: '<?php echo C('web_server_url_admin'); ?>',
data:formData,
processData:false,
contentType:false,
type: 'POST',
dataType: "JSON",
success: function (data) {
alert();
},
error: function () {
layer.msg('图片上传连接失败，请检查您的网络连接',function(){layer.closeAll();})
},
});
});
}
});
});
