Javascript Object push() function
I have a javascript object (I actually get the data through an ajax request):
var data = {};
I have added some stuff into it:
data[0] = { "ID": "1"; "Status": "Valid" }
data[1] = { "ID": "2"; "Status": "Invalid" }
Now I want to remove all objects with an invalid status (but keep everything the ordering same):
var tempData = {};
for ( var index in data ) {
if ( data[index].Status == "Valid" ) {
tempData.push( data );
}
}
data = tempData;
In my mind, all of this should work, but I am getting an error that tempData.push
is not a function. I understand why it isn't the same as an array, but what could I do otherwise?
push()
is for arrays, not objects, so use the right data structure.
var data = [];
// ...
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };
// ...
var tempData = [];
for ( var index=0; index<data.length; index++ ) {
if ( data[index].Status == "Valid" ) {
tempData.push( data );
}
}
data = tempData;
Objects does not support push property, but you can save it as well using the index as key,
var tempData = {};
for ( var index in data ) {
if ( data[index].Status == "Valid" ) {
tempData[index] = data;
}
}
data = tempData;
I think this is easier if remove the object if its status is invalid, by doing.
for(var index in data){
if(data[index].Status == "Invalid"){
delete data[index];
}
}
And finally you don't need to create a var temp –
You must make var tempData = new Array();
Push is an Array function.
