javascript – Das native JS in Angular ist ungültig und kann nicht verwendet werden

Question

Komplettes HTML und Controller, Angular-Anweisungen können ebenfalls verwendet werden, aber einige Teile müssen nativen JS-Code schreiben, es wurde jedoch festgestellt, dass der native JS nicht verwendet werden kann
html:

<a type="button" onclick="printOrder()">直接打印</a>

js in:

var LODOP; //声明为全局变量  
function printPreview(){  
    //创建小票打印页  
    CreatePrintPage();  
    //打印预览  
    LODOP.PREVIEW();      
};  
/**  
* 样例函数,服务器确认订单后执行  
*/  
function printOrder() {  
          
    //创建小票打印页  
    CreatePrintPage();  
    //开始打印  
    LODOP.PRINT();    
      
};            
function CreatePrintPage(json) {  
    //json 创建模拟服务器响应的订单信息对象  
    var json = {"title":"XXXXX订单信息", "name":"张三", "phone": "138123456789", "orderTime": "2012-10-11 15:30:15",

Aber Fehler:

Ich habe einen sehr einfachen Code ausprobiert, aber onclick funktioniert nicht, warum

Answer 1

你既然用了angular,那应该会有若干个controller,你应该在 需要点击的链接 所在的controller中声明对应的事件回调方法，并且应该通过ng-click指令绑定对应的事件回调

Answer 2

可以定义函数为window.fun=function(){}然后就可以在ng中调用window.fun了。因为angular是不直接操作dom的所以，，

Answer 3

angular全家桶都可以搞定。如果不想用angular的数据绑定就没必要用框架
