我正在對服務器進行ajax調用,並希望接收數組以供進一步處理。我是一名初學者,對我真正在做的事情感到困惑。下面是我到目前爲止的一個片段。它運行良好,直到我嘗試處理返回的數據。我認爲我的問題是我並不真正瞭解如何形成正確的迴應以及如何處理它。
JAVASCRIPT/JQUERY:
var shoppingList = {
// SOME CODE BEFORE
'foodIngredients' : function() {
// Send a list of food ids and receive an array of necessary ingredients. Make the returned array unique.
$.ajax({
url: 'http://localhost:8000/ingredients/',
// ingredients.html template:
// [{% for item in ingredients %}{% if forloop.last %}{{ item.id }}{% else %}{{ item.id }},{% endif %}{% endfor %}]
type: 'POST',
data: JSON.stringify(shoppingList.selectedFoods),
dataType: 'text',
cache: 'false',
success: function(result){
console.log(result); // [33,85,88,89,91]
shoppingList.returnedIngredients = result;
shoppingList.uniqueIngredients = _.unique(shoppingList.returnedIngredients);
console.log(shoppingList.uniqueIngredients); // [,3,,,8,5,9,1,] <-- NOT OK; Expected [33,85,88,89,91]
}
});
},
// SOME CODE AFTER
};
Ingredients查看:
def ingredients(request):
if request.is_ajax():
ourid = json.loads(request.raw_post_data)
ingredients = Ingredience.objects.filter(food__id__in=ourid)
t = get_template('ingredients.html')
html = t.render(Context({'ingredients': ingredients,}))
return HttpResponse(html)
else:
html = '<p>This is not ajax</p>'
return HttpResponse(html)
你可以粘貼/成分/視圖的代碼? – jpic
郵政編碼爲_.unique – iJade
@jpic:添加配料視圖。 – finspin
