我有两个名称为IMEI和城市的下拉列表,如下所示:
<HTML>
<body>
Select Programming font:
<select name="IMEI">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">$</option>
</select>
<select name ="city">
<option value="jhansi">Jhansi</option>
<option value="Delhi">Delhi</option>
<option value="Mumbai">Mumbai</option>
<option value="Kanpur">Kanpur</option>
</select>
</body>
</html>
期望的行为是:当选择城市名称时,IMEI列表启用;否则它被禁用。
我怎样才能做到这一点?
提前致谢!

$(function () {
var sel_imie = $('select[name="IMEI"]');
sel_imei.prop('disabled', true); //disable IMEI select
$('select[name ="city"]').change(function () {
sel_imei.prop('disabled', false); //enable when value of city select is changed
});
});

试试这个,
<select name="IMEI" disabled="disabled" id="IMEI">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">$</option>
</select>
<select name ="city" id="city">
<option value="jhansi">Jhansi</option>
<option value="Delhi">Delhi</option>
<option value="Mumbai">Mumbai</option>
<option value="Kanpur">Kanpur</option>
</select>

$('#city').on('change',function(){
$('#IMEI').attr('disabled',false);
});

试试这种方式
HTML CODE:
CITY :<select name="city">
<option value="jhansi">Jhansi</option>
<option value="Delhi">Delhi</option>
<option value="Mumbai">Mumbai</option>
<option value="Kanpur">Kanpur</option>
</select>
<br/>
IMEI :<select name="IMEI">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">$</option>
</select>
JQUERY CODE:
$('select[name=IMEI]').prop('disabled',true);
$('select[name=city]').on('change',function () {
$('select[name=IMEI]').prop('disabled',false);
});

禁用选择并更新插件。使用已选择的触发器:已更新以禁用选择小部件。
$('#RefundType').prop('disabled', true).trigger("chosen:updated");
