Make sure to wrap your code in ready handler:
确保将您的代码包装在就绪处理程序中：
$(function(){
$("input[name='setAlg']").attr("disabled", true);
});
But If you are using the same class for those input fields (as per your question title), you need to try this instead:
但是，如果您对这些输入字段使用相同的类（根据您的问题标题），则需要尝试以下操作：
$(function(){
$("input.myclass").attr("disabled", true);
});
Where myclassis supposed to be the class name used for those input fields.
Wheremyclass应该是用于这些输入字段的类名。

Chris Pebbles suggestion should work fine, but I am confused. In your question's title, you specificall state "jQuery disable all button of a css class", however, you then provide an example which shows that you really want to disable all buttons that have a nameattribute of setAlg.
Chris Pebbles 的建议应该没问题，但我很困惑。在您的问题标题中，您具体说明了“jQuery 禁用css 类的所有按钮”，但是，您随后提供了一个示例，表明您确实想要禁用所有具有name属性的按钮setAlg。
Two points come to mind. First, your buttons, since they all have the same name may produce unexpected results for you when the user submits your form (if this is what they do, but I may be wrong here). If this is the case, the you probably really do want to set all of them to the same class, not name.
想到两点。首先，您的按钮，因为它们都具有相同的名称，当用户提交您的表单时，它们可能会为您产生意想不到的结果（如果这是他们所做的，但我可能在这里错了）。如果是这种情况，您可能真的希望将它们全部设置为同一个class，而不是name。
<input class="setAlg">...
Second point is that if you do want to make your jQuery to work with a class, you'll need to do:
第二点是，如果您确实想让 jQuery 与类一起工作，则需要执行以下操作：
$("input.setAlg").attr("disabled","disabled");
I hope this was helpful.
我希望这可以帮到你。

I think you forgot quotes
我想你忘记了报价
$("input[name='setAlg']").attr('disabled','true');
If this doesn't work then maybe your selection doesn't work
如果这不起作用，那么您的选择可能不起作用
