I am trying to send a javascript array via the url.But it fails

function viewReport(mode,someid){
    if(mode==0){
        var para= new Array();
        para['para1'] = 'para1'||0;
        para['para2']= 'para2' || 0;
        console.log(para);
        window.open('somePDFView/'+para,'_blank'); 
    }else{
        var para=[];
        var paraelements={
          para1:'anotherpara1'||0,
          para2:'anotherpara2'||0
        };
        para[0]=paraelements;
        window.open('somePDFView/'+para,'_blank'); 
    }
}

On if part(mode=0), the para array is not sending any more and on else part (mode=1) the para is sends like this:

somePDFView/[object Object]

Which shows the error:

The URI you submitted has disallowed characters

How can we send an array via url.I can't use Ajax (because its a popup window) or session or storing in a temporary table.Also how can we retrieve this value in the controller.

Edit:

I miss an important thing that I am using codeigniter. Then I think it disallows special characters like - &,=,[,],etc..So if any other methods available for sending data as an array?..

You might want to use serialize or param – Brewal Aug 24 at 9:58
You could encode it. But a URL has a maximum length to send variables I think, so don't make it too long. – putvande Aug 24 at 10:01
serialize? k I will study that one and try it... – manuthalasseril Aug 24 at 10:02
Don't use arrays with non-numeric keys! – Felix Kling Aug 24 at 10:15
I think you should first study why string + array produces strange results... (hint: what happens when you combine a car with an apple?) – Christian Aug 24 at 10:50

You can also use Json here. Use JSON.stringify().

Note: Don't sent long data over a URL. There is a limit for sending data via url and it will end up in a corrupted data if exceeded the limit. For large data, use POST method.

function viewReport(mode,someid){
    var json;
    if(mode==0){
        var para= new Array();
        var paraelements={
      para1:'para1'||0,
      para2:'para2'||0
    };
    para[0]=paraelements;
    json = JSON.stringify(para);
    window.open('somePDFView/'+json,'_blank'); 
    }else{


 var para=[];
    var paraelements={
      para1:'anotherpara1'||0,
      para2:'anotherpara2'||0
    };
    para[0]=paraelements;
    json = JSON.stringify(para);
    window.open('somePDFView/'+json,'_blank'); 
  }
}

If you are using php, use json_decode() to convert json into PHP variable.Also refer, http://php.net/manual/en/function.json-decode.php

Its also showing the error --The URI you submitted has disallowed characters. – manuthalasseril Aug 24 at 10:19
Use console.log(json) and check what data is being return before sending through url. – raduns Aug 24 at 10:22
the data is correctly assigned and json contains all that values but it can't send – manuthalasseril Aug 24 at 10:28
Are you sending the data by using query string? – raduns Aug 24 at 10:32
yes.I am using query string. – manuthalasseril Aug 24 at 10:34

Use jQuery.param() and change your data structure :

var para = {
    para1:'anotherpara1'||0,
    para2:'anotherpara2'||0
};

window.open('somePDFView/'+jQuery.param(para), '_blank');

In alert its working . but on window.open its not working .why??? – manuthalasseril Aug 24 at 10:19
You can't do this. See this tread or this one. – Brewal Aug 25 at 14:04

You can try to pass them as individual parameters:

var para1 = '1';
var para2 = '2';
var para= new Array();
para.push('para[]=' + para1 || 0);
para.push('para[]=' + para2 || 0);
var url = para.join('&');
alert(url)

Returns para[]=1&para[]=2. Note that this solution does not require jQuery.

sorry its not working... – manuthalasseril Aug 24 at 10:10
Post edited. The code is now tested and working. – Milan Milanov Aug 24 at 10:19
Now i can see the parameters on url--salesexePDFView/parat[] = 1&parat[] = 2 but it shows The URI you submitted has disallowed characters. – manuthalasseril Aug 24 at 10:24
I removed the spaces between parat[] and the = sign. It should work now. – Milan Milanov Aug 24 at 10:27
sorry .its not working :( – manuthalasseril Aug 24 at 10:30
