这个实现的是点击下拉框选择身份证则验证身份证，点击护照则验证护照，那如何进行反选？就是点击文本框输入身份证号，那么下拉框只能选择身份证，文本框输入的是护照，点击下拉框只能选择护照
<script>
$(document).ready(function () {
$("#idType").change(function () {
if ($("#idType option:selected").text()=="身份证"){
SelectCard();
}else if ($("#idType option:selected").text()=="护照"){
SelectpassPort();
}
});
});
