console.log($scope.filteredOffers);嗨,所有人都希望检查json中的字符串,就像来自params的字符串现在想要检查整个json并只显示与之相关的数据。请检查我的代码..换句话说,想要根据来自url(即将到来)的参数来显示数据。
.controller('mixCtrl', function($scope,$http,$stateParams) {
$http.get("http://tools.vcommission.com/api/coupons.php?apikey=e159f64e3dd49fddc3bb21dcda70f10c6670ea91aac30c7cb1d4ed37b20c45b8").then(function (response) {
$scope.myData = response.data;
$scope.offerName = ''; //set initially
$scope.selectedIndex = -1;
$scope.filteredOffers = [];
// $scope.link1 = [];
$scope.da = $stateParams.offer_name;
var a = $scope.da;
console.log(a);
$scope.filteredOffers = $scope.myData.filter(function(a) {
for (var i=0;i<$scope.myData.length;i++)
{
$link =$scope.myData[i].offer_name;
if (a==$link)
{
return a ;
console.log(a );
}
//console.log(a );
}
// return offer.offer_name == $scope.da;
console.log($scope.da);
});
});
/*
$scope.showData = function(offer_name, index) {
$scope.offerName = offer_name;
$scope.filteredOffers = $scope.myData.filter(function(offer) {
return offer.offer_name == $scope.offerName;
});
$scope.selectedIndex = index;
}*/
$scope.dealopen = function(a){
for (var i=0;i<$scope.myData.length;i++)
{
//console.log($scope.data[i].name);
$link=$scope.data[i].name;
console.log($link);
if ($link==$a)
{
$window.open($link,"_self","location=yes");
//console.log($a);
}
}
}
})
Html
<div ng-repeat="offer in filteredOffers">
<div class="couponCode">{{offer.coupon_code}}</div>
<div class="couponTitle">{{offer.coupon_title}}</div>
<div class="couponDescription">{{offer.coupon_Description}}</div>
</div>

你错误地使用了Array.filter()函数!
之前:
$scope.filteredOffers = $scope.myData.filter(function(a) {
for (var i=0;i<$scope.myData.length;i++)
{
$link =$scope.myData[i].offer_name;
if (a==$link)
{
return a ;
console.log(a );
}
//console.log(a );
}
// return offer.offer_name == $scope.da;
console.log($scope.da);
});
之后(根据正确的语法):
$scope.filteredOffers = $scope.myData.filter(function(a) {
if (check condition)
{
return true ;// when true is returned the json held in a gets pushed into the filteredOffers array
}
else{
return false;//when false is returned, the json held in 'a' is ignored and not pushed into the filteredOffers array
}
});
Array.filter's Doc Link 但是你使用的逻辑有问题。如果你能准确地告诉我你想要做什么,我或许可以帮助你。

如果您经常在应用程序中处理json和数组,那么在您的应用程序中集成loadash或underscore会更好。
在加载控制器文件之前,将以下代码添加到HTML中。
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
查看http://tools.vcommission.com/api/coupons.php?apikey=e159f64e3dd49fddc3bb21dcda70f10c6670ea91aac30c7cb1d4ed37b20c45b8
的响应后,下面的代码将为您提供与offer_name匹配的数组。
$http.get("http://tools.vcommission.com/api/coupons.php?apikey=e159f64e3dd49fddc3bb21dcda70f10c6670ea91aac30c7cb1d4ed37b20c45b8").then(function (response) {
$scope.filteredOffers = [];
var offerName = $stateParams.offer_name;
$scope.filteredOffers = _.filter(response.data, ["offer_name",offerName]);
})
