使用jquery 1.6 .prop()将控件设置为只读 [英] Setting a control to readonly using jquery 1.6 .prop()

问题描述

随着jQuery 1.6的发布，关于SO的建议通常是开始使用您以前使用attr()的prop().

With the release of jQuery 1.6, the recommendation on SO has been to generally start using prop() where you used to use attr().

当我想将一个元素设置为只读时会发生什么?

What happens when I want make an element readonly?

$('.control').prop('readonly', 'readonly');
$('.control').prop('readonly', true);

这些似乎都不使控件变为只读.将元素设为只读是规则的例外吗?

Neither of these seem to make the control readonly. Is making an element readonly the exception to the rule?

推荐答案

问题是属性名称区分大小写.试试:

The problem is that the property name is case-sensitive. Try:

$('.control').prop('readOnly', true);

尽管我真的不知道为什么这需要jQuery.效果也一样:

Though really I don't know why this requires jQuery. This works just as well:

document.getElementsByClassName("control")[0].readOnly = true;
