$("a[target='_blank']").attr('target', 'sometarget');Do you mean something like that?
你的意思是这样吗？

尝试
$("a[target=_blank]").each(function () {
var href = $(this).attr("href"); // retrive href foreach a
$(this).attr("href", "something_you_want"); // replace href attribute with wich u want
// etc
});

If you're specifically looking for hrefvalues which have blank values then do the following
如果您专门寻找href具有空白值的值，请执行以下操作
$('a[href=""]').each(function() {
$(a).attr('href', 'theNewUrl');
});
This will catch only anchor tags which have a href attribute that is empty. It won't work though for anchors lacking an href tag
这将仅捕获具有空的 href 属性的锚标记。但是对于缺少 href 标签的锚点，它不起作用
<a href="">Link 1</a> <!-- Works -->
<a>Link 2</a> <!-- Won't work -->
If you need to match the latter then do the following
如果您需要匹配后者，请执行以下操作
$('a').each(function() {
var href = $(this).attr('href') || '';
if (href === '') {
$(this).attr('href', 'theNewUrl');
}
});
