bootstrap-dn-validator.js :
// bootstrap自定义插件有两种方式来实现参数配置
// 1.json数据格式
// 2.html attribute(属性)配置
// 1.创建闭包
(function(root,factory,plug){
// 4.创建闭包对象
return factory(root.jQuery,plug);
})(window,function($,plug){ // 3.传入 $ plug
// 9.默认参数 保证健壮性
var __DEFS__ = {
trigger:"change"
};
// 11.规则引擎
var __RULES__ = {
required:function(){
// console.log('required' + this.val());
return this.val()!=="";
},
regex:function(){
return new RegExp(this.data("dv-regex")).test(this.val());
},
email:function(){
return /^[a-z0-9]+([._\\-]*[a-z0-9])*@([a-z0-9]+[-a-z0-9]*[a-z0-9]+.){1,63}[a-z0-9]+$/.test(this.val());
},
uri:function(){
return /^[a-zA-Z0-9][-a-zA-Z0-9]{0,62}(\.[a-zA-Z0-9][-a-zA-Z0-9]{0,62})+\.?$/.test(this.val());
},
// 扩展
integer:function(){
return /^[0-9]*[1-9][0-9]*$/.test(this.val());
},
greaterthan:function(){
return Number(this.val())>Number(this.data("dv-greaterthan"));
},
lessthan:function(){
return Number(this.val())<Number(this.data("dv-lessthan"));
}
}
// 5.进行插件扩展 可以对jQuery进行重命名(通过创建作用,命令别名)
// 创建dnValidator插件
$.fn[plug] = function(options){ // 8.options 用户传参
// 10.继承
$.extend(this,__DEFS__,options);
// 6.找到表单中所有的input标签
var $fileds = this.find("input").not("[type=button],[type=reset],[type=submit]"); // 需要验证的表单域
// console.log($fileds.size()); // input个数
// 7.绑定事件
$fileds.on(this.trigger,function(){
var $field = $(this); // 被验证的目标对象
var result = true; // 14.验证结果,默认通过
$field.next().remove(); // 17.验证之前先把之前的错误信息移除掉
// 12.迭代rule
$.each(__RULES__,function(rule,valider){ // rule规则 valider验证器
// 13.判断目标对象被哪些规则验证
if($field.data("dv-"+rule)){
// 我需要验证rule这个规则
// console.log($field.attr("name") + "需要验证" + rule + "规则");
// 15.判断,只要有一个验证失败,就停止验证
result = valider.call($field); // true false call改变作用域
if(!result){ // 验证失败
// 16.显示提示信息
$field.after("<p>" + $field.data("dv-" + rule + "-message") + "</p>");
}
return result;
}
});
});
}
},"dnValidator")
// 2.匿名函数调用
// 参数1：window对象
// 参数2：function(){} 回调函数
// 参数3：插件名称
