我使用angular-ui-mask作为SSN，初始ui-mask是“999-99-9999”，但在模糊时我需要将SSN 123-45-6789字符显示为XXX-XX-6789。
我尝试将ui-mask设置为XXX-XX-9999，但它显示的是“XXX-XX-”末尾SSN的前4位数字，而不是最后4位数字。
这是HTML代码
<input class="btnDropdown" id="phoneTextInput" ui-mask="{{uimaskpattern}}" ui-mask-placeholder-char=""
ng-focus="applymask()"
ng-blur="removemask(contact.contactDetails.attributeDetails.contact)"
md-minlength="10" md-maxlength="10" name="Phone_{{$index}}" ng-model="contact"
placeholder="">
这是Typescript代码
public applymask() {
this.uimaskpattern = "999-99-9999";
}
public removemask(ssn, ev) {
if (ssn) {
console.log(ssn);
this.uimaskpattern = "AAA-AA-9999";
}
}
有一个名为jquery.maskedinput的jQuery插件可能对此有所帮助。
您可以使用此插件通过创建自定义指令并在其中调用库来屏蔽输入。这是一个工作示例，应该在输入字段失去焦点时屏蔽输入：
var app = angular.module('myapp', []);
app.controller('MainCtrl', function($scope) {
$scope.ssn = '';
});
app.directive("ssnMasker", function () {
return {
require: "ngModel",
link: function (scope, elem, attr, ngModel) {
$(elem).mask("999-99-9999"); // 9 represents a numeric character in this library
var temp;
var regxa = /^(\d{3}-?\d{2}-?\d{4})$/; // regex to define formatting for a SSN
$(elem).focusin(function () {
$(elem).val(temp);
});
$(elem).on("blur",function () {
temp = $(elem).val();
if (regxa.test($(elem).val())) { // check for match
$(elem).val("XXX-XX" + temp.slice(6)); // change displayed value
}
});
}
}

</html>这可能也是一种尝试的方法 - 虽然它是Angular 1.x风格 - 所以可能有更多的当前/ Angular 2方法来做到这一点。
