How to use NameSpace to take values to next page

Question

I'm using Navigation App Template for one of my Win 8 app. I want to capture a value on homepage and then use it one next page. How do I do that ? My code is like below. It gives me value as undefined on the next page.

WinJS.UI.Pages.define(

"/pages/home/home.html", {

varopValue, opRangeValue;

   

varopValues = {

opSign: opValue,

        opRangeVal: opRangeValue

    };

// read opValue and opRangeValue from html elements and assign to opSing and OpRangeVal.

    WinJS.Namespace.define(

"OperationValues", opValues);

}

On page2.js I'm trying to read that value:

WinJS.UI.Pages.define(

"/pages/practice/practice.html", {

       

        ready:

function(element, options) {

           

// TODO: Initialize the page here.

            console.log(

"OP :"+ OperationValues.opSign);    // this gives op : undefined.

        },

How do I do it without having any global variables?

Thanks

Answer 1

Hi Sonal,

Why not use: WinJS.Navigation.navigate("/pages/secondpage.html", yourvalue)? Then in your second page, you could receive the value by "options" in ready function. Take a look at the documentation: navigate function

And while reading the data, I think OperationValues is enough, OperationValues.opSign will definitely give a undefined result.

            console.log(
"OP :"+ OperationValues);    // this should be ok. 
        },
