aur*_*enC 8 javascript arrays multidimensional-array angularjs
我试图使用ng-repeat指令在html中显示一个二维数组.我可以显示第一个维度(表格行)但第二个(表格数据)不起作用.我已经看到很多使用对象,JSON,键值数据结构的解决方案......但是我找不到只适用于包含其他数组的数组的东西.这是一些不成功的尝试.
HTML :(不起作用)
<div ng-app = "grid" ng-controller = "gridCtrl">
<table>
<tr ng-repeat = "y in grid">
<td ng-repeat = "x in y"></td>
</tr>
</table>
</div>
HTML :(不起作用)
<div ng-app = "grid" ng-controller = "gridCtrl">
<table>
<tr ng-repeat = "y in grid">
<td ng-repeat = "x in grid[$index]"></td>
</tr>
</table>
</div>
JS:
var grid = angular.module("grid", []);
grid.controller("gridCtrl", function($scope)
{
$scope.grid = [[empty, empty, empty, empty, empty],
[empty, empty, empty, empty, empty],
[empty, empty, empty, empty, empty],
[empty, empty, empty, empty, empty],
[empty, empty, empty, empty, empty]];
});
工作范例:
HTML:
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>
document.write('<base href="' + document.location + '" />');
</script>
<script data-require="angular.js@1.4.x" src="https://code.angularjs.org/1.4.9/angular.js" data-semver="1.4.9"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<p>Hello {{name}}!</p>
<div>
<table>
<tr ng-repeat="y in grid">
<td ng-repeat="x in y track by $index">{{x}}</td>
</tr>
</table>
</div>
</body>
</html>
JS:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.grid = [["empty", "empty", "empt", "empt", "empty"],
["empty", "empty", "empt", "empt", "empty"]];
});

由于你的数组数据包含重复,你想添加track by唯一ID,所以我添加了track by $index更多关于这个https://docs.angularjs.org/error/ngRepeat/dupes
