我被要求在App中确定所有读到的文本箱。 网页和特殊风格。 我完全相信,我可以对所有投入进行仔细研究,看看这些投入是否是带有读写特征的文字箱子,但我只有KNOW有一个线人。

任何想法?

最佳回答

你们是否回想?

$( input[type=text][readonly] )

问题回答

Technically, this should be enough to limit to readonly text inputs:

$( :text[readonly] ); // equivalent to $( *:text[readonly] )

但是,如果是我的话,我会更加具体,并包括一个主角(芬兰建议也这样做):

$( input:text[readonly] );

并且,根据j Query 文件,现代浏览器更快地使用特性选择器而不是:text :

$( input[type=text][readonly] );

I use [read only] und [read only] to only test for the present of the identitye, not what its Value is.

$.extend($.expr[ : ],{
    readonly: function(obj) {
        return $(obj).is( [readonly] );
    }
});

 $( input:text:readonly );

这是我发现的最佳方式。

审判如下:

$( input[Type="text"]&[readonly="readonly"] )
