Question

我有jQuery代码，我试图将一个类值放在一个变量＆amp;然后尝试在if else条件下使用该变量值＆amp;与静态值比较FCL＆＃39;但那不起作用。类名是＆＃39; kuuj＆＃39; ＆安培;此类值可以是（LCL，FCL，BULK，AIR）。

＆＃13;

var xxssees = $('.kuuj').val();
if(xxssees == "FCL")
{
$('#sonal').html(xxssees);	
}
else 
{
   $('#sonal').html('hello');	
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<strong>Solution : </strong><label id="sonal" style="color:Green"></label><br />

Answer 1

1。val() is only applicable for an input element然后您的代码将正常运行。检查如下： -

$(document).ready(function(){
  var xxssees = $('.kuuj').val();
  if(xxssees == "FCL"){
     $('#sonal').text(xxssees);  
  }else {
     $('#sonal').text('hello');  
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<strong>Solution : </strong><label id="sonal" style="color:Green"></label><br />

<input class="kuuj" value = "FCLs">

2.如果kuju类在输入之外的任何其他元素上，则使用.text()或.html()来获取值。检查以下内容： -

$(document).ready(function(){
  var xxssees = $('.kuuj').html();  // you can use .text() also
  if(xxssees == "FCL"){
      $('#sonal').html(xxssees);  //you can use .text() also
  }else {
      $('#sonal').html('hello');  //you can use .text() also
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<strong>Solution : </strong><label id="sonal" style="color:Green"></label><br />

<div class="kuuj">FCLs</div>

Answer 2

您需要添加输入字段而不是标签

而不是

<label id="sonal" style="color:Green"></label>

您添加

 <input type="text" id="sonal" value="" />

随时询问是否需要进一步的帮助
