我想切片JSON数组,但得到以下错误:
对象#没有方法'slice'
以下是我的代码:
$scope.getPagedDataAsync = function (pageSize, page, searchText) {
setTimeout(function () {
var data;
programService.query({
id: $routeParams.id
}, function (result) {
data = {
'program': result
};
data = JSON.stringify(data);
data = JSON.parse(data);
$scope.setPagingData(data,page,pageSize);
});
}, 100);
};
$scope.setPagingData = function(data, page, pageSize){
var pagedData = data.slice(0, 3);
$scope.myData = pagedData;
$scope.totalServerItems = data.length;
if (!$scope.$$phase) {
$scope.$apply();
}
};
JSON数据:
{programId:1,
programName:project1,
programContent:content1,
programStartDate:2012-01-01,
templateId: '1'}
我想按如下方式对数组进行切片:programId,1,programName,project1,...
我很困惑,请帮忙。
答案 0 :(得分:0)
尝试
var data = {
programId:1,
programName:'project1',
programContent:'content1',
programStartDate:'2012-01-01',
templateId: '1'
}
var array = [];
for(var key in data){
if(!data.hasOwnProperty(key)){
continue;
}
array.push(key, data[key])
}
console.log(array, array.slice(0, 4))
