我有这个
$('#div').attr("hidden", true);
i tried:
我试过:
var a = $('#div').attr("hidden");
var b = $('#div').attr("hidden").val();
var c = $('#div').hidden;
var a = $('#div').disabled;
i just want to know whether hidden is true or false. does anybody know? my research results are all about forms and inputs.
我只想知道隐藏是真的还是假的。有人知道吗?我的研究结果都是关于形式和投入的。

attribute will never be true
, it can have strings only.
jQuery has the data
functions for objects other than strings:
属性永远不会是true
,它只能有字符串。
jQuery 具有data
用于字符串以外的对象的函数:
$('#div').data("hidden", true); // set the "hidden" data
var flag = $('#div').data("hidden"); // get the "hidden" data (true)
If you wanted to hide the div
, use .hide()
:
如果您想隐藏div
,请使用.hide()
:
$('#div').hide();
And you check if the div is visible with :visible
\ :hidden
然后您检查 div 是否可见:visible
\:hidden
$('#div').is(':visible'); // Or $('#div').is(':hidden')

Alternatively you could use
或者你可以使用
$('#div').toggle(showOrHide);
where showOrHide is a bool of true of false to hide or show.
其中 showOrHide 是隐藏或显示的真假布尔值。
This is the same as doing
这和做一样
if ( showOrHide == true ) {
$('#div').show();
} else if ( showOrHide == false ) {
$('#div').hide();
}
Hope this helps
