jQuery $.removeAttr("selected") changes selected option
提问by Maxim
Please take a look at the example: http://jsfiddle.net/HHDpK/1/
请看一下例子：http: //jsfiddle.net/HHDpK/1/
As you see the difference between two choosers is only the line
如您所见，两个选择器之间的区别仅在于行
$("#chooser-1 .y").removeAttr("selected");
But as a result their states are different (especially in Chrome). Am I missing anything, or it is a bug?
但结果它们的状态是不同的（尤其是在 Chrome 中）。我错过了什么，还是一个错误？

Looks like internal bug of jQuery with attributes.
看起来像带有属性的 jQuery 的内部错误。
Note that in older versions, before .prop()was introduced in 1.6 version, it works as expected.
请注意，在旧版本中，.prop()在 1.6 版本中引入之前，它按预期工作。
In the newer versions, just use .prop()to deal with such properties of elements:
在较新的版本中，仅用于.prop()处理元素的此类属性：
$("#chooser-1 .x").prop("selected", "selected");
$("#chooser-1 .y").removeProp("selected");
More than that - using .removeProp("selected")on the element selected previously with prop()will cause the original selection to return instead of having nothing selected - ideal behavior.
更重要的是 -.removeProp("selected")在先前选择的元素上使用 withprop()将导致原始选择返回而不是没有选择任何东西 - 理想的行为。

I found the above answer failed as well, I had to set the prop to false to get the selected items to not be.
我发现上面的答案也失败了，我必须将道具设置为 false 才能使所选项目不存在。
$("#chooser-1 .x").prop("selected", false);
removeProp cause undesired effects such as not being able to re-select the options again.
removeProp 会导致不良影响，例如无法再次重新选择选项。
