I assume you mean "how do you remove the 'keypress' attribute from the input", in which case this would work
我假设你的意思是“你如何从输入中删除‘keypress’属性”，在这种情况下这会起作用
<script>
$(document).ready(function(){
$("#cleanMsg").removeAttr("keypress");
});
</script>
If you want to bind to a keypress, you should do it in the jQuery way (refer to the docs), with this code the above attribute within the input tag is redundant
如果你想绑定到一个按键，你应该用 jQuery 的方式来做（参考文档），使用这段代码，输入标签中的上述属性是多余的
<script>
$(document).ready(function(){
$("#cleanMsg").keypress(function(){
//do something here
});
});
</script>

To further answer the general question, you can remove any keypress handlers added with Jquery with:
要进一步回答一般问题，您可以删除任何使用 Jquery 添加的按键处理程序：
$('#foo').unbind("keypress");
unbind() without arguments removes all handlers.
不带参数的 unbind() 删除所有处理程序。

use unbind method
使用解绑方法
$('#foo').unbind();
