我想使用angularjs ng-repeat在表內顯示json數據，但由於我沒有訪問json數據的第一行，所以表的第一行仍爲空。我想省略表內的第一行json數據。如何實現這個？處理JSON數據內部angulrjs ng-repeat
我的JSON格式：
var myApp = angular.module('myApp',['ui.bootstrap']);
myApp.controller('MyCtrl', function($scope) {
$scope.list = [
{"dept_id":"d10","dname":"dname"},
{"eid":"10","ename":"nam1"},
{"eid":"20","ename":"nam2"},
{"eid":"30","ename":"nam3"},
{"eid":"40","ename":"nam4"}
];
$scope.list1 = [
{"eid":"10","ename":"nam1"},
{"eid":"20","ename":"nam2"},
{"eid":"30","ename":"nam3"},
{"eid":"40","ename":"nam4"}
];
});<html>

<div class="container">
<div ng-app="myApp" ng-controller="MyCtrl">
<table class="table table-striped table-bordered">
<thead>
<tr>
\t <th>Sr</th>
<th>Employee ID</th>
\t <th>name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="data in list">
<td> {{$index+1 }} </td>
<td> {{ data.eid }} </td>
<td> {{ data.ename }} </td>
</tr>
</tbody>
</table>
But I want like this :
<table class="table table-striped table-bordered">
<thead>
<tr>
\t <th>Sr</th>
<th>Employee ID</th>
\t <th>name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="data in list1">
<td> {{$index+1 }} </td>
<td> {{ data.eid }} </td>
<td> {{ data.ename }} </td>
</tr>
</tbody>
</table>
</div>
</div>
工作！但你能解釋一下嗎？ ng-if =「$ index」是否意味着索引不是0？以及增量如何工作？ – query
是的，這裏的$ index類似於標準數組迭代：0,1,2,3 ...因此，要打印的第一個元素在其範圍內獲得$ index = 0。因爲我們不想打印它，所以ng-if來幫助 - 它只允許在條件爲TRUE時打印元素，並且在javascript中，0等於FALSE。下一個要創建的元素獲取$ index = 1，所以它會通過ng-if條件等。 –
