How to set "style=display:none;" using jQuery's attr method?

Question

Why not just use $('#msform').hide()? Behind the scene jQuery's hide and show just set display: none or display: block.

hide() will not change the style if already hidden.

based on the comment below, you are removing all style with removeAttr("style"), in which case call hide() immediately after that.

e.g.

$("#msform").removeAttr("style").hide();

The reverse of this is of course show() as in

$("#msform").show();

Or, more interestingly, toggle(), which effective flips between hide() and show() based on the current state.

As an alternative to hide() mentioned in other answers, you can use css() to set the display value explicitly:

$("#msform").css("display","none")

$(document).ready(function(){
var display =  $("#msform").css("display");
    if(display!="none")
    {
        $("#msform").attr("style", "display:none");
    }
});

You can use the hide and show functions of jquery. Examples

In your case just set $('#msform').hide() or $('#msform').show()

Based on the comment we are removing one property from style attribute.

Here this was not affect, but when more property are used within the style it helpful.

$('#msform').css('display', '')

After this we use

$("#msform").show();

You can just use: $("#msform").hide(). This sets the element to display: none
