[英]How to disable an href given a condition?
我有一个链接,我需要根据用户的权限来禁用它。 以下是链接的htmn:
<div ng-repeat="userAgreement in journalist.userAgreements">
<div class="row" ng-repeat="attachment in userAgreement.attachments">
<div class="col-sm-12" style="color: #2a98d4">
<ul style="margin-bottom: 0px; padding-left: 1.5em;">
<li class="fa fa-check-circle" style="font-size: 1.1em; margin: 3px;">
<a target="_blank" href="{{attachment.url}}" ng-click="agreementPermission($event)" class="cursor-pointer" style="font-family: FranklinITCProLight">{{getAttachmentName(userAgreement.agreement, attachment)}}</a>
</li>
</ul>
</div>
</div>
</div>
<div ng-show="!hasAttachments">
<div class="col-sm-12" style="color: #2a98d4">
<ln code="journalist.completed.documents.empty" args=""></ln>
</div>
</div>
</div>
( ng-click
不起作用)
这是该文件的js指令:
define(["app"], function (app) {
return app.directive('completedAgreements',[
function () {
return {
restrict: 'E',
templateUrl: '/directives/completed-agreements.html',
link: function ($scope, elm, attrs) {
$scope.hasAttachments = false;
$scope.getAttachmentName = function(agreement, attachment) {
$scope.hasAttachments = true;
if(attachment.templateId) {
return attachment.name;
} else {
if(agreement.type == 'DIRECT_DEPOSIT') {
return "Payment Documents"
} else {
var specialization = agreement.specialisation.toLowerCase();
return specialization.charAt(0).toUpperCase() + specialization.slice(1) + " Agreement";
}
}
}
}
};
}
])
});
ng-click中的函数:
$scope.agreementPermission = function(e) {
if (!SecurityService.canViewAgreements()) {
showError($uibModal, "You do not have permission to access this attachment. Please contact an administrator.", null, null, null, null, "Access Denied");
e.preventDefault();
}
};
由于我是javascript新手,因此不确定此函数是否在正确的位置。 这是另一个控制器文件,应该在html的js指令中吗? 因此,基本上,当没有权限的用户单击链接时,将触发showError框,如果他们具有权限,则页面将重定向到该链接。 任何建议将不胜感激! 让我知道是否需要提供更多信息!:-)
a.disable{ pointer-events: none; }
<!--You can add css class to disable the link (anchor), example: --> <a ng-class="{'disable': isAvailable(product.id)}">see product</a>
将标签<a>
标签重写为<a disabled>
<a>
<a disabled>
参见http://www.w3schools.com/tags/ref_attributes.asp
它也应该可以通过javascript作为对象进行编辑。 寻找类似的东西:
object = document.getElementById("MyElem");
object.disabled = true;
要么
object.active = false;
onclick="onClickFunc(event, {{ element.id or class }})"
function onClickFunc(event, somedata) {
event.preventDefault(); // Stops the default behavior
// ...
}
// event.preventDefault(); 停止链接的默认行为。
使用按钮代替链接。 给它CSS class =“ btn btn-link”(Bootstrap)。 在ng-click上调用函数AgreementPermission。
