[英]Add Item to Sub-Array in an array
I have an array我有一个数组
vm.prdGroups = [{
type_id: '1',
group_name: '',
is_required: false,
position: 0,
options: {
item_name: '',
item_price: '',
position: 0
}
}];
How do I add a new array to the options key, to have something like this如何向 options 键添加一个新数组,以获得类似的内容
vm.prdGroups = [{
type_id: '1',
group_name: '',
is_required: false,
position: 0,
options: {
item_name: '',
item_price: '',
position: 0
},
{
item_name: '',
item_price: '',
position: 0
}
}];
First thing is your vm.prdGroups.options is not a array.首先是你的 vm.prdGroups.options 不是一个数组。 You need to make it a array and then push new values to it.
您需要将其设为数组,然后向其推送新值。
let vm={}; vm.prdGroups = [{ type_id: '1', group_name: '', is_required: false, position: 0, options: { item_name: '', item_price: '', position: 0 } }]; let temp= vm.prdGroups[0].options; vm.prdGroups[0].options = [] vm.prdGroups[0].options.push(temp,'some other object'); console.log(vm.prdGroups);
I realized my options wasn't actually an array, so I couldn't possibly push to it, I made it an array, and it made the task doable我意识到我的选项实际上不是一个数组,所以我不可能推送到它,我把它变成了一个数组,它使任务变得可行
vm.prdGroups = [
{
type_id: 1,
group_name: '',
is_required: false,
position: 0,
options: [{
item_name: '',
item_price: '',
position: 0
}]
}
];
And I could push to the array inside an array with the use of index, so the method to push was this我可以使用索引推送到数组内的数组,所以推送的方法是这样的
vm.addPrdItem = function (index) {
console.log(index);
var itemLength = vm.prodAttribs.product_groups[index].options.length - 1;
vm.productItems = {
item_name: '',
item_price: '',
position: itemLength + 1
};
vm.product_groups[index].options.push(vm.productItems);
}
Thanks to all who answered, appreciate.感谢所有回答的人,不胜感激。
