javascript - Angular js ng-click不起作用

我正在尝试使用 JavaScript 添加表单验证。当我添加 

 document.getElementById("one").setAttribute("ng-click", "insertData()");

到validateForm函数，按下按钮后它不起作用。

当我将该行移出 validateForm 函数时，它可以工作，但不会执行表单验证。

这是我的代码:

最佳答案

好的，您要做的不是 angularjs 的工作方式；我建议你阅读angularjs form documentation ，尤其是绑定(bind)到表单和控制状态一章。您的代码似乎是 jquery 和 angularjs 之间的冲突，我建议您重新阅读 angularjs phonecat tutorial或者，更好的是，尝试新版本的 angular
