Jquery not passing array via ajax

Question

I am trying to send javascript array to php via ajax, but it is not sending, here is my code

var ArrayAmounts = new Array();
ArrayAmounts["P1"] = "16150";

$.ajax({
    url:"myajax",
    cache:'false',
    type:'POST',
    data:{Arr:ArrayAmounts},
    success: function(data){
        console.log(data);
    },error: function(xhr, AjaxOptions, ThrownError){
        ShowMessage(xhr.responseText);
    }
});

but when I am making array like this:

 var ArrayAmounts = new Array();
 ArrayAmounts[0] = "16150";

it is passing the array, but I want the key as alphanumeric. please help.

its an array not an object if you assing to it index it will happen.i think you need object literals — zabusa

So you don't need an array here, you'll need to use an object like this :

var Amounts = {};
Amounts["P1"] = "16150";

$.ajax({
    url:"myajax",
    cache:'false',
    type:'POST',
    data:{Arr: Amounts},
    success: function(data){
        console.log(data);
    },error: function(xhr, AjaxOptions, ThrownError){
        ShowMessage(xhr.responseText);
    }
});

should be data : { Arr : Amounts }, not data : { Arr : ArrayAmounts }, or even simpler, data : Amounts, but yes, that's the way to go

Your problem is related to the kind of data you are sending because as the documentation says:

"It is converted to a query string, if not already a string. It's appended to the url for GET-requests. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key based on the value of the traditional setting"

Official documentation for more details

you can declare the array like this: var ArrayAmounts = new Array(); ArrayAmounts = ["16150"]; and then your ajax call work normally

Use like this

var ArrayAmounts = {};
ArrayAmounts.P1 = "16150";

var dataArray = {Arr: ArrayAmounts};

$.ajax({
  url:"myajax",
  cache:'false',
  type:'POST',
  data: dataArray ,
  success: function(data){
    console.log(data);
  },error: function(xhr, AjaxOptions, ThrownError){
    ShowMessage(xhr.responseText);
 });
