You can use join().

It converts each array element into a string. It acts much like toString(), moreover you can determine the separator.

var arr = ["HTML","CSS","JS"]; 
...
alert(arr.join(' - '));

Use javascript forEach() function to get result 

var array = ["a","b","c"];

solution:

array.forEach(function(data){alert(data)});

To display array values properly try this :

saveData: function()
    {
        var p=new Array();
        var element = $('input');
        for(var i=0;i<element.length;i++)
        {
            //alert($(element[i]).val());
            p[0] = $(element[i]).val();
        }
        alert(p.join("\n"));

    },

In JavaScript you could just

for(i=0; i<p.length; ++i){
    alert(p[i]);
}

so if p is an array containing ["one","two","three"] your browser will alert "one", "two" and then "three" in the loop.

You need to create an array and then push all the values to it, instead you are resetting it in the loop

var element = $('input');
var p = element.map(function () {
    return this.value
}).get();
alert(JSON.stringify(p));//or alert(p);

changing your code will be

var element = $('input');
var p = [];
for (var i = 0; i < element.length; i++) {
    p.push($(element).eq(i).val());
}
alert(JSON.stringify(p));//or alert(p)
