如何设置“style=display:none;” 使用 jQuery 的 attr 方法？

Question

Following is the form with id msform that I want to apply style="display:none" attribute to.

<form id="msform" style="display:none;">
</form>

Also the check should be performed before adding the "style=display:none;"property. That is if it is already set like in above code it should not set again.

But if it's not set then it should.

How should I achieve this? Please help me.

Answer 1

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.

eg

$("#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.

Answer 2

作为其他答案中提到的hide()的替代方法，您可以使用css()显式设置display值：

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

Answer 3

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

Answer 4

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

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

Answer 5

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();

Answer 6

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

Answer 7

You can use the jquery attr() method to achieve the setting of teh attribute and the method removeAttr() to delete the attribute for your element msform As seen in the code

$('#msform').attr('style', 'display:none;');


$('#msform').removeAttr('style');

Answer 8

Please try below code for it :

$('#msform').fadeOut(50);

$('#msform').fadeIn(50);
