二維數組遍歷
獲取兩個index 其中 獲取父域裏的index 的方法爲： {{$parent.index}} 獲取當前index 的方法爲: {{$index}}
注意： 不要用 ng-if 會出現 兩個index 重置成值相同 可以用 ng-show
其中二位數組需要用到 file 就需要通過一下代碼 進行值的綁定
<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" >刪除行</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":""}],
]
操作二維數組 ：
$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;
$scope.files[index1].push({});
};
或者 根據 item 判斷 index 值 因爲如果用了過濾器 傳入的index 不是實際index值
items.splice(items.indexOf(item),1);
angular 綁定 input 的file文件：
<div class="form-group">
<input type="file" id="file_{{$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;
};
