如何设置"style = display:none;"使用jQuery的attr方法? [英] How to set "style=display:none;" using jQuery's attr method?

问题描述

以下是我要对其应用style ="display:none"属性的ID为msform的表单.

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

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

此外，还应该在添加"style=display:none;"属性之前执行检查.那就是说，如果已经像上面的代码中那样设置了它，则不应再次设置它.

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.

但是，如果未设置，则应该设置.

But if it's not set then it should.

我应该如何实现呢?请帮助我.

How should I achieve this? Please help me.

推荐答案

为什么不只使用$('#msform').hide()?在后台，jQuery的hide和show只需设置display: none或display: block.

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

hide()如果已经隐藏，则不会更改样式.

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

根据下面的评论，您将删除所有带有removeAttr("style")的样式，在这种情况下，请在此之后立即调用hide().

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

例如

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

与之相反的当然是show()，如

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

或更有趣的是，toggle()可以根据当前状态在hide()和show()之间进行有效切换.

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