Question

我可以在选中复选框时禁用文本框，但如果有任何内容，我无法弄清楚如何清除文本框。

  <input type="text" id="form_sc1"/>
  <input type="checkbox" id="form_setchange"/>

JQuery

                $(document).ready(function(){
                 if($('input.form_setchange').is(':checked')){
                       $("#form_sc1").attr("disabled", "disabled");
                 }

Answer 2

试试这个：

$('input:checkbox').on('click', function(){
    $('input:text').prop('disbaled', 'disabled');
    $('input:text').val('');
});

Answer 3

你也可以尝试这个 -

$('#form_setchange').attr("value", "");

OR

$('#form_setchange').val('');

Answer 4

if($('input.form_setchange').is(':checked')){
     $("#form_sc1").prop("disabled", true).val('');
}

Answer 5

您可以尝试下面的代码吗

 $('#form_setchange').change(function() {
   var $check = $(this);
   if ($check.prop('checked')) {
     $("#form_sc1").val('');
     $("#form_sc1").attr("disabled", "disabled"); 
   } else {
     $("#form_sc1").removeAttr("disabled"); 
   }
});
