二维数组遍历
获取两个index 其中 获取父域里的index 的方法为： {{$parent.index}} 获取当前index 的方法为: {{$index}}
注意： 不要用 ng-if 会出现 两个index 重置成值相同 可以用 ng-show
其中二位数组需要用到 file 就需要通过一下代码 进行值的绑定
<div ng-show="$index==0">
<button type="button" ng-click="addFile($parent.$index,$index)" class="btn btn-primary" >增加行</button>
</div>
<div ng-show="$index>0">
<button type="button" ng-click="deFile($parent.$index,$index)" class="btn btn-primary" >删除行</button>
</div>
$scope.files=[
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
[{"fileTitle": "", "fileNum": "", "fileReply": "", "fileTime": "","file":""}],
]
操作二维数组 ：
$scope.deFile = function (index1,index2) {
$scope.indexNumByFile= $scope.indexNumByFile-1;
$scope.files[index1].splice(index2,1);
};
$scope.addFile = function (index1,index2) {
$scope.indexNumByFile= $scope.indexNumByFile+1;
$scope.files[index1].push({});
};
或者 根据 item 判断 index 值 因为如果用了过滤器 传入的index 不是实际index值
items.splice(items.indexOf(item),1);
angular 绑定 input 的file文件：
<div class="form-group">
<input type="file" id="file_{{$index}}" name="file_{{$parent.$index}}" ng-model="fileOneOne.file" class="form-control" οnchange="angular.element(this).scope().fileNameChanged(this)">
</div>
$scope.fileNameChanged = function (el) {
var filexx = el.files[0];
var index=el.id.replace('file_','');
var parentIndex=el.name.replace('file_','');
$scope.files[parentIndex][index].file=filexx;
};
