I have a function called insert which takes two parameters (name and telnumber).
When I call this function I want to add to an associative array.
So for example, when I do the following:
insert("John", "999");
insert("Adam", "5433");
I want to it so be stored like this:
[0]
{
name: John, number: 999
}
[1]
{
name: Adam, number: 5433
}
Something like this should do the trick:
var arr = [];
function insert(name, number) {
arr.push({
name: name,
number: number
});
}
I would use something like this;
var contacts = [];
var addContact = function(name, phone) {
contacts.push({ name: name, phone: phone });
};
// Usage
addContact('John', '999');
addContact('Adam', '5433');
I don’t think you should try to parse the phone number as an integer as it could contain white-spaces, plus signs (+) and maybe even start with a zero (0).
var users = [];
users.push({name: "John", number: "999"});
users.push({name: "Adam", number: "5433"});
If you want you can add your function to Array.prototype.
Array.prototype.insert = function( key, val ) {
var obj = {};
obj[ key ] = val;
this.push( obj );
return this;
};
And use it like this.
var my_array = [].insert("John", "999")
.insert("Adam", "5433")
.insert("yowza", "1");
[
0: {"John":"999"},
1: {"Adam":"5433"},
2: {"yowza":"1"}
]
I will assume you're using some array reference with insert:
var arr;
function insert(na, nu) {
nu = Number(nu) || 0;
//alternatively
nu = parseInt(nu, 10);
arr.push({ name: na, number: nu });
}
arr = [];
insert("John", "999");
insert("Adam", "5433");
You can also just assign them directly they don't need to be inserted first
var form = document.getElementById('ourinput').elements;
var out={};
for(var i=0;i<form.length;i++)
{
var row=form[i];
if(row.checked){out[row.id]=row.value;}
}
the html part
<form id="ourinput" onsubmit="return false;">
<table>
<tr>
<td><input type="checkbox" id="q1" value="A1"><label for="q1">A1</label></td>
<td><input type="checkbox" id="q2" value="A2"><label for="q2">A2</label></td>
<td><input type="checkbox" id="q3" value="A3"><label for="q3">A3</label></td>
</tr>
<tr><td><button onclick="test()">Submit</button></td></tr>
<table>
</form>
in my case the form is just a bunch of checkboxes and this is the part that makes an associative array with the id's as the keys for each checkbox that has been checked.
There is no such term as an "associative array" in JavaScript, though you can use following:
var list = [];
function insert(name, number) {
list.push({
name: name,
number: number
});
}
