它有效 - 当输入 #key1 为空时,我无法单击按钮。但我需要使用两个输入 - #key1 和 #key2。待办事项 - 当两者都为空或 1/2 时,没有人不能点击按钮。谢谢!!<script type='text/javascript' src='http://code.jquery.com/jquery.min.js'></script><script type='text/javascript'> $(function() { $('#key1').keyup(function() { if ($(this).val() == '') { //Check to see if there is any text entered // If there is no text within the input ten disable the button $('.enableOnInput').prop('disabled', true); } else { //If there is text in the input, then enable the button $('.enableOnInput').prop('disabled', false); } }); });</script>

不确定我是否理解但告诉我
<script type='text/javascript'>
$(function() {
var button1 = $('#key1');
var button2 = $('#key2');
function keyUp(){
console.log('1', button1.val());
console.log('2', button2.val());
var hasValue = ( button1.val() !== '' || button1.val() !== '');
$('.enableOnInput').prop('disabled', hasValue);
}
button1.keyup(keyUp);
button2.keyup(keyUp);
});
</script>
