剛學習form驗證。不得不說form驗證是比較豐富的。下面來個小例子。
1、情景：看電影選座位！
2、具體要求：當輸入座位號時，進行校正。其中1已經被選。如果輸入為1，則提交按鈕置為無效，並且給出提示，如果輸入為2，則不給出提示，允許提交
3、實際效果：
4、程式碼範例：
1 <!DOCTYPE HTML> 2 <html ng-app="app"> 3 <head> 4 <meta charset="utf-8"/> 5 <script src="jquery-1.10.2.min.js"></script> 6 <script src="angular.js"></script> 7 <style type="text/css"> 8 input.ng-invalid.ng-dirty { 9 background-color: yellow;10 }11 </style>12 </head>13 <body ng-controller="controller">14 <h1>正確性校正</h1>15 <form name="myform" novalidate>16 請輸入你選的電影座位順序17 <input type="text" ng-model="seq" name="seq" ng-keyup="isDup(seq);"/>18 <span ng-show="myform.seq.$error.seq">座位已經有人坐了!</span>19 <button ng-disabled="myform.$invalid" id="btn">提交</button>20 </form>21 22 <script>23 angular.module(‘app‘,[]).controller("controller",function($scope){24 $scope.flag = false;25 $scope.seq=1;//初始值為1，並且1已經被選了26 $scope.isDup=function(seq){27 if(seq == 1)28 {29 //var btn=document.getElementById(‘btn‘);30 //btn.setAttribute(‘disabled‘,‘disabled‘);31 $scope.myform.seq.$setValidity("seq", false)32 //$scope.seq=2;33 }34 else{35 //var btn=document.getElementById(‘btn‘);36 //btn.removeAttribute(‘disabled‘,‘disabled‘);37 $scope.myform.seq.$setValidity("seq", true);38 //$scope.seq=1;39 }40 }41 });42 43 </script>44 </body>45 </html>
