I want to store a dynamic id every time in the array of object format
Suppose I have 3 ids one is
id = 250
and the second one is id = 650
and the third one is id = 850
and
I want to store it like
[
{
id:250,
how_many_times = 1
},
{
id:650,
how_many_times = 2
},
{
id:850,
how_many_times = 1
}
]
But when I tried to set the id it's showing me this error
Property 'id' does not exist on type '{ id: string; }[]'
I have tried the following lines of code
first I created an array like this
popUpShowData = [
{
id : '',
how_many_times:0
}
];
then I tried to set the value like this
getPopup(dynamicId) {
this.popUpShowData.id = dynamicId;
this.popUpShowData.how_many_times = 1;
}
but getting this error
Property 'id' does not exist on type '{ id: string; }[]'
CodePudding user response:
popUpShowData
is an array, so you have to set the id
property to one of its items, not on it directy:
this.popUpShowData[0].id = dynamicId;
this.popUpShowData[0].how_many_times = 1;
In general, you should in addition pass the index
of the item to the function, so you would know which item to update:
getPopup(index, dynamicId) {
this.popUpShowData[index].id = dynamicId;
this.popUpShowData[index].how_many_times = 1;
}
