问题描述
需要使用jQuery在选择框中禁用已选择的选项.我希望它像 asmselect 一样变灰.
Need to disable already selected options in select box using jQuery. I'd like it to grey out like asmselect.
在此处进行测试.
//JS
$("#theSelect").change(function(){
var value = $("#theSelect option:selected").val();
var theDiv = $(".is" + value);
theDiv.slideDown().removeClass("hidden");
});
$("div a.remove").click(function () {
$(this).parent().slideUp(function() { $(this).addClass("hidden"); });
});
//HTML
<body>
<div class="selectContainer">
<select id="theSelect">
<option value="">- Select -</option>
<option value="Patient">Patient</option>
<option value="Physician">Physician</option>
<option value="Nurse">Nurse</option>
</select>
</div>
<div class="hidden isPatient">Patient <a href="#" class="remove" rel="Patient">remove</a></div>
<div class="hidden isPhysician">Physician <a href="#" class="remove" rel="Patient">remove</a></div>
<div class="hidden isNurse">Nurse <a href="#" class="remove" rel="Patient">remove</a></div>
</body>

推荐答案
将此行添加到您的change事件处理程序
Add this line to your change event handler
$("#theSelect option:selected").attr('disabled','disabled')
.siblings().removeAttr('disabled');
这将禁用选定的选项，并启用所有以前禁用的选项.
This will disable the selected option, and enable any previously disabled options.
如果您不想重新启用以前的版本，只需删除该行的这一部分:
If you did not want to re-enable the previous ones, just remove this part of the line:
.siblings().removeAttr('disabled');
要在单击删除"时重新启用，请将其添加到点击处理程序中.
To re-enable when you click remove, add this to your click handler.
$("#theSelect option[value=" + value + "]").removeAttr('disabled');
