get array value from get method

Question

How to get separate values of array in javascript?

in one page:

var c=new Array(a); (eg: a={"1","2"}) window.location="my_details.html?"+ c + "_"; and in my_details.html :

my_details.htm:

var q=window.location.search;     
alert("qqqqqqqqqqqqq " + q);    
var arrayList = (q)? q.substring(1).split("_"):[];       
var list=new Array(arrayList);     
alert("dataaaaaaaaaaaa " +  decodeURIComponent(list)   + "llll " );

But i am not able to get individual array value like list[0] etc
How to get it?

thanks

decodeURIComponent() will return you a String; you need to do something like:

var delim = ",",
    c = ["1", "2"];

window.location = "my_details.html?" + c.join(delim);

And then get it back out again:

var q = window.location.search,
    arrayList = (q)? q.substring(1).split("_"):[],       
    list = [arrayList];     
    arr = decodeURIComponent(list).split(delim);

This will use the value of delim as the delimiter to make the Array a String. We can then use the same delimiter to split the String back into an Array. You just need to make sure delim is available in the scope of the second piece of code.

If you do console.log(decodeURIComponent(list)) what do you see? Are the data items delimited by spaces?

But Now I am facing the problem with [1, value list[0] value. how to resolve that?

Do you mean that the Array you get out contains a nested Array?

Smitha Over a year ago

nope, the value of arr[0] is "[1" instead of just "1". The value "[" gets added to arr[0].!!

Sorry, my mistake. Try removing list = [arrayList];. And using arr = decodeURIComponent(arrayList).split(delim);.
