Angularjs 角度JSURL验证

我们必须验证用户为URL字段提供的值

系统询问Facebook、Twitter、Google+等

有人能给我们推荐最好的方法吗

我们使用以下模式

谢谢，

您可以开始使用输入类型作为

url

范例

<form name="form1" ng-controller="x">
    <label>Enter Site Name:</label>
    <input type="url" ng-model="initialwebsite" name="name" required />
    <span style="color:red" ng-show="form1.name.$error.required">
    You Can't Leave This Field Empty</span>
    <span style="color:red" ng-show="form1.name.$error.url">
    Sorry Not a Valid URL, Don't Forget to Use http://</span>
    <input type="submit" value="Submit"/>
</form>

你到底需要验证什么？

（https？：\/\/（？：www\.|（？！www））[^\s\.]+\.[^\s]{2，}www\.[^\s]+\.[^\s]{2，}）

试试这个

<form name="form1" ng-controller="x">
    <label>Enter Site Name:</label>
    <input type="url" ng-model="initialwebsite" name="name" required />
    <span style="color:red" ng-show="form1.name.$error.required">
    You Can't Leave This Field Empty</span>
    <span style="color:red" ng-show="form1.name.$error.url">
    Sorry Not a Valid URL, Don't Forget to Use http://</span>
    <input type="submit" value="Submit"/>
</form>
