bootstrap3-validation.js bootstrap 的jquery 表单验证

/* =========================================================
*
* 在原作者的基础修改支持 bootstrap3
*
* check-type=
*   required 不能为空，并在后面自动加*号
*   url  表示 输入网址
*   date 日期格式 xxxx-xx-xx
*   mail 邮箱
*   number 数字，可以整型，浮点型。
*   char
*   chinese 中文
* mail-message="扩展提示内容" ， 可以扩展data-message,url-message
* minlength="6" 表示长度大于等于6
* range="2.1~3"   表示值在[2.1~3]之间，并check-type="number"
* range="2.1,2,4,5"   表示值在只能填现数字，并check-type="number"
*
*
* 例如:
* $("form").validation(function(obj,params){
*     if (obj.id=='mail'){
*       $.post("/verifymail",{mail :$(obj).val()},function(data){
*         params.err = !data.success;
*         params.msg = data.msg;
*       });

功能参数

check-type=
required 不能为空，并在后面自动加*号
url  表示 输入网址
date 日期格式 xxxx-xx-xx
mail 邮箱
number 数字，可以整型，浮点型。
char
chinese 中文
mail-message="扩展提示内容" ， 可以扩展data-message,url-message
mixlength="6" 表示长度大于等于6
range="2.1~3"   表示值在[2.1~3]之间，并check-type="number"
range="2.1,2,4,5"   表示值在只能填现数字，并check-type="number"

例如:
$("form").validation(function(obj,params){
if (obj.id=='mail'){
$.post("/verifymail",{mail :$(obj).val()},function(data){
params.err = !data.success;
params.msg = data.msg;
});
}},
{reqmark:false}
);

使用方法：

js:

<script type="text/javascript">
$(function(){
//1. 简单写法：
$("form").validation();
$("button[type='submit']").on('click',function(event){
// 2.最后要调用 valid()方法。
if ($("form").valid(this,"error!")==false){
//$("#error-text").text("error!"); 1.0.4版本已将提示直接内置掉，简化前端。
return false;
}
})  })
</script>
