我想要那个，
#search_domain设置焦点时，#submit_replace_button将被禁用。#domain_name_url关注它时，#submit_search_button将被禁用为此，我有这段代码
$(document).bind('keyup', function(e)
{
if (e.keyCode === 13)
{
//console.log("Replace focus :"+$('#domain_name_url').is(':focus'))
//console.log("Search focus :"+$('#search_domain').is(':focus'))
if($('#domain_name_url').is(':focus'))
{
console.log("Replace focus :"+$('#domain_name_url').is(':focus'))
console.log("Search focus :"+$('#search_domain').is(':focus'))
console.log("Inside Replace :")
$('#submit_search_button').prop("disabled",true);
$('#submit_replace_button').prop("disabled",false);
$("#submit_replace_button").click();
}
else if($('#search_domain').is(':focus'))
{
console.log("Replace focus :"+$('#domain_name_url').is(':focus'))
console.log("Search focus :"+$('#search_domain').is(':focus'))
console.log("Inside Search :")
$('#submit_replace_button').prop("disabled",true);
$('#submit_search_button').prop("disabled",false);
$("#submit_search_button").click();
}
else
{
}
}
});

$(document).ready(function() {
$('#search_domain').on('focus', function() {
$('#submit_replace_button').attr('disabled', true);
});
$('#search_domain').on('blur', function() {
$('#submit_replace_button').attr('disabled', false);
});
$('#domain_name_url').on('focus', function() {
$('#submit_search_button').attr('disabled', true);
});
$('#domain_name_url').on('blur', function() {
$('#submit_search_button').attr('disabled', false);
});
});

你可以在元素本身上使用onfocus来激活一个禁用脚本的函数： W3Schools onfocus 然后使用onblur来撤消它 W3Schools onblur
这很容易使用

使用此代码禁用按钮： -
$('your element').attr("disabled","disabled");
使用此功能启用
$('your element').removeAttr("disabled");
