【问题描述】：
输入框需要以下验证：
1) 长度输入框最多取3个整数长度值（不允许小数）
2) 高度输入框应取 3 个整数和小数，最多 2 位 它第一次工作正常，但单击 + 按钮后（打开新行 1 附近）相同的输入字段正在打开，但现在：在新即使我对输入框使用相同的类，框验证也不起作用，即新添加的输入框采用任意数量的数字和字符。
在 keyup 功能中它正在工作，但是如果用户按下任何键它对新打开的行不起作用，那么在这两种情况下如何使其在 keypress 上工作；按键验证有效，但按键无效
var app = angular.module('Calc', []);
var inputQuantity = [];
$(function() {
$(".form-control").each(function(i) {
inputQuantity[i]=this.defaultValue;
$(this).data("idx",i); // save this field's index to access later
});
$(".form-control").on("keyup", function (e) {
var $field = $(this),
val=this.value,
$thisIndex=parseInt($field.data("idx"),10); // retrieve the index
// window.console && console.log($field.is(":invalid"));
// $field.is(":invalid") is for Safari, it must be the last to not error in IE8
if (this.validity && this.validity.badInput || isNaN(val) || $field.is(":invalid") ) {
this.value = inputQuantity[$thisIndex];
return;
}
if (val.length > Number($field.attr("maxlength"))) {
val=val.slice(0, 5);
$field.val(val);
}
inputQuantity[$thisIndex]=val;
});
});
app.controller('Calc_Ctrl', function ($scope, $http) {
$scope.choices = [{id : 'choice1', l2 : 0, b2 : 0}];
$scope.areas = [{id : 'choice2', total : 0}];
$scope.addNewChoice = function () {
var newItemNo = $scope.choices.length + 1;
$scope.choices.push({
'id' : 'choice' + newItemNo, l2 : 0, b2 : 0
});
};
$scope.removeChoice = function () {
var lastItem = $scope.choices.length - 1;
if (lastItem !== 0) {
$scope.choices.splice(lastItem);
}
};
