有没有办法验证单个输入字段中的一个或多个电子邮件地址？
我目前正在探索的方式是创建一个自定义指令,如果检测到逗号,将会将输入拆分成不同的电子邮件.这是我到目前为止
angular.module('myApp')
.directive('multipleEmails',function () {
return {
require: 'ngModel',link: function(scope,element,attrs,ctrl) {
ctrl.$parsers.unshift(function(viewValue) {
var emails = viewValue.split(',');
// loop that checks every email,returns undefined if one of them fails.
});
}
};
});

编辑2：结果我可以使用角度1.3

.directive('multipleEmails',function () {
return {
require: 'ngModel',ctrl) {
ctrl.$parsers.unshift(function(viewValue) {
var emails = viewValue.split(',');
// loop that checks every email,returns undefined if one of them fails.
var re = /\S+@\S+\.\S+/;
// angular.foreach(emails,function() {
var validityArr = emails.map(function(str){
return re.test(str.trim());
}); // sample return is [true,true,false,false]
console.log(emails,validityArr);
var atLeastOneInvalid = false;
angular.forEach(validityArr,function(value) {
if(value === false)
atLeastOneInvalid = true;
});
if(!atLeastOneInvalid) {
// ^ all I need is to call the angular email checker here,I think.
ctrl.$setValidity('multipleEmails',true);
return viewValue;
} else {
ctrl.$setValidity('multipleEmails',false);
return undefined;
}
// })
});
}
};
});
