The z-index property defaults to auto, as explained in the MDN documentation.
Despite setting the z-index to 1 using the following code:
$("body").css("z-index", 1);
Upon retrieving the value of z-index with this code:
$("body").css("z-index");
The return value remains auto.
Can someone explain why this is happening and suggest a way to correctly retrieve the current z-index value?
Typically, z-Index is not effective on elements with a position:static.
It is only functional on elements with a position:relative/absolute/fixed.
This solution may be effective:
elementSelector
{
position:relative;
z-index:1;
}

To ensure that z-index works effectively, you must first set the position of the element...
For a demonstration, check out this jsfiddle
<div id="hello">deepak sharma</div>
<input type="button" id="set10" value="set zindex = 10" />
<input type="button" id="set20" value="set zindex = 20" />
<input type="button" id="get" value="get" />
$(function(){
$("#set10").click(function(){
$("#hello").css({"z-index":"10","position":"relative"});
});
$("#set20").click(function(){
$("#hello").css({"z-index":"20","position":"relative"});
});
$("#get").click(function(){
alert($("#hello").css("z-index"));
});
});
You can also set the position:relative in your CSS, eliminating the need to set it in your jQuery code.
