I have this:
var one = ['12','24','36'];
var two = ['10','20','30'];
If I do:
alert(one) I have: 12,24,36. And it's ok.
I need to have the name of the array from another function, where I call it from a for like this:
var test = [one,two]
for (i = 0; i < test.length; i++) {
alert(test[i]);
}
I have "12,24,36" and then "10,20,30" in the alert, but I need the name of the array, not the content. How to do?
I want two alert with: "one" and "two", the name of Array.
Use an object to hold your arrays:
var obj = {
one: ['12','24','36'],
two: ['10','20','30']
}
for (var p in obj) {
console.log(p); // log the key
}
Alternatively you can use Object.keys(obj) to retrieve an array of the object keys.
And if you need to log the array contents:
for (var p in obj) {
console.log(obj[p]); // log the array contents
}
Yes, I agree with elad.chen. You can try something like:
var objects = [
{name:"one",value:['12','24','36']},
{name:"two",value:['12','24','36']}
];
for(var i=0;i<objects.length;i++){
console.log(objects[i].name);
console.log(objects[i].value);
}
You can use an "Object Literal" and use the property name as the name, and the value as the array..
For example:
var arrays = {
"one": [1,2,3],
"two": [1,2,3]
}
for ( var k in arrays ) {
alert('"Array name" = ' + k)
alert('"Array value" = ' + arrays[k].toString() )
}
At some place, the name must be set. While Javascript is can add properties to objects, this can be used for a name property without changing the behaviour of the arrays.
var one = ['12', '24', '36'];
one.name = 'one';
var two = ['10', '20', '30'];
two.name = 'two';
var test = [one, two], i;
for (i in test) {
document.write(test[i].name + '<br>');
}
