Check Checkbox Disabled (Jquery)
提问by user1595357
The purpose is to;
If checkbox is disabled, do nothing.
If checkbox is enabled and checked, set the style of a button.
Here is what I've got so far;
目的是为了;
如果复选框被禁用,则什么都不做。
如果复选框已启用并选中,则设置按钮的样式。
这是我到目前为止所得到的;
$(document).ready(function (e) {
$(".checkbox").live("click", function () {
if ($(this).hasAttribute('disabled')) {
return false;
}
var isAnyChecked;
$("input[type=checkbox]").each(function () {
var checkedValue = $(this).attr("checked");
if (checkedValue == "checked") {
isAnyChecked = true;
}
});
if (isAnyChecked) {
$("#<%= btnConfirm.ClientID %>").css("display", "block");
} else {
$("#<%= btnConfirm.ClientID %>").css("display", "none");
}
}); });
I've tried .is(':disabled')
, .hasAttr()
, .prop()
and .attr()
. Any help would be greatly appreciated.
我试过.is(':disabled')
, .hasAttr()
,.prop()
和.attr()
。任何帮助将不胜感激。

You have to check whether the disabled
attribute is true: .attr('disabled')
.
您必须检查该disabled
属性是否为真:.attr('disabled')
。
Or, better, use .is(':disabled')
.---
或者,更好的是,使用.is(':disabled')
.---
EDIT:So it seems that .attr
is now deprecated for this use (see http://api.jquery.com/attr/)
The preferred way is:
编辑:所以现在似乎.attr
已弃用此用途(请参阅http://api.jquery.com/attr/)首选方法是:
$('#myCheckbox').prop('disabled')
It has to be noted that this still work as of today:
必须指出的是,这在今天仍然有效:
$('#myCheckbox').is(':disabled')

Also you can try use this:
你也可以尝试使用这个:
$("#myCheckBox").is('[disabled]');
Works for me to determine if an element is disabled, while others solutions (.disabled
, .is(':disabled')
, .attr('disabled')
, .prop('disabled')
) not.
为我工作以确定元素是否被禁用,而其他解决方案 ( .disabled
, .is(':disabled')
, .attr('disabled')
, .prop('disabled')
) 不是。
