我的表格是这样的：
<div class="row" id="yesAuth">
<div class="col-md-6" ng-class="{ 'has-error': invalid.basicAuthForBackendUsername, 'has-success': valid.basicAuthForBackendUsername}">
<div class="form-group">
<label for="basicAuthForBackendUsername">basic auth username *</label>
<input type="text" name="basicAuthForBackendUsername" class="form-control" placeholder="basic auth username" ng-model="api.basicAuthForBackendUsername" ng-required="true">
<span id="helpBlock" class="help-block" ng-show="help.basicAuthForBackendUsername.required">basic auth username is required.</span> </div>
</div>
</div>
我根据选择的值显示/隐藏div。当值为“no”时，我隐藏div，当它为“yes”时，我显示div。
当我验证表单并选择值“是”时，隐藏div中的字段不会考虑ng-required。 （所以出现下一页，但我不想要它，因为它是空的。）
$(function() {
$('#yesAuth').hide();
$("#basicAuth").change(function() {
if ($("#basicAuth option:selected").val() == 'yes') {
$('#yesAuth').show();
$('#basicAuthForBackendUsername').attr("ng-required", "true");
alert("VOILA" + $('#basicAuthForBackendUsername').attr("ng-required"))
} else {
$('#yesAuth').hide();
$('#basicAuthForBackendUsername').attr("ng-required", "false");
alert("VOILA" + $('#basicAuthForBackendUsername').attr("ng-required"));
}
});
});
如何解决我的问题？

非常感谢。

当您使用ngModel绑定值api.basicAuth时，您可以直接将Angular expression传递给ngRequired指令。
将您的观点用作
<input type="text" ng-required="api.basicAuth == 'yes'" ng-model="api.basicAuthForBackendUsername">
