global variables with jquery mobile multipage

Question

I have a multipage design with jquery mobile. On the first site i call a function with onklick() to fill a global array with values. Now i want to display this values on the second site, but i can't manage to display them with document.write(array)

To append data to the DOM you first need to select an element to append it to, then in your case iterate through the array, adding each index's value to the DOM:

//here is the array of values
var myArr = [...];

//wait for out page to initialize
$(document).delegate('#my-page-id', 'pageinit', function () {

    //create an array to buffer the output
    var output = [];

    //use a fast loop to add the value at each index to an array,
    //in this case I'm adding some HTMl markup to it as well
    for (var i = 0, len = myArr.length; i < len; i++) {
        output.push('<li>' + myArr[i] + '</li>');
    }

    //check to see if there were any indexes in the array
    if (output.length) {

        //append a list-view widget with the info from myArr to the content section of the current page
        $(this).children('.ui-content').append('<ul data-role="listview">' + output.join('') + '</ul>').trigger('create');
    }
});
