如何在不使用显式注释的情况下修复角度,并且不能在严格模式下调用

时间:2022-09-04 11:04:18

I am using strict mode and Angular 1.4.7 , I get the following error:

我使用的是严格模式和角1。4.7,我得到如下错误:

Error: [$injector:strictdi] function($scope, $element, $attrs, mouseCapture) is not using explicit annotation and cannot be invoked in strict mode

The angular generated url for the error is:

误差产生的角度url为:

https://docs.angularjs.org/error/$injector/strictdi?p0=function($scope,%20$element,%20$attrs,%20mouseCapture

https://docs.angularjs.org/error/ $喷射器/ strictdi ? p0 =函数(范围、美元% 20美元的元素,% 20 $ attrs % 20 mousecapture

And the following is the service

以下是服务

angular.module('mouseCapture', [])

//
// Service used to acquire 'mouse capture' then receive dragging events while the mouse is captured.
//
.factory('mouseCapture', function ($rootScope) {

    //
    // Element that the mouse capture applies to, defaults to 'document' 
    // unless the 'mouse-capture' directive is used.
    //
    var $element = document; 

    //
    // Set when mouse capture is acquired to an object that contains 
    // handlers for 'mousemove' and 'mouseup' events.
    //
    var mouseCaptureConfig = null;

    //
    // Handler for mousemove events while the mouse is 'captured'.
    //
    var mouseMove = function (evt) {

        if (mouseCaptureConfig && mouseCaptureConfig.mouseMove) {

            mouseCaptureConfig.mouseMove(evt);

            $rootScope.$digest();
        }
    };

    //
    // Handler for mouseup event while the mouse is 'captured'.
    //
    var mouseUp = function (evt) {

        if (mouseCaptureConfig && mouseCaptureConfig.mouseUp) {

            mouseCaptureConfig.mouseUp(evt);

            $rootScope.$digest();
        }
    };

    return {

        // 
        // Register an element to use as the mouse capture element instead of 
        // the default which is the document.
        //
        registerElement: function(element) {

            $element = element;
        },

        //
        // Acquire the 'mouse capture'.
        // After acquiring the mouse capture mousemove and mouseup events will be 
        // forwarded to callbacks in 'config'.
        //
        acquire: function (evt, config) {

            //
            // Release any prior mouse capture.
            //
            this.release();

            mouseCaptureConfig = config;

            // 
            // In response to the mousedown event register handlers for mousemove and mouseup 
            // during 'mouse capture'.
            //
            $element.mousemove(mouseMove);
            $element.mouseup(mouseUp);
        },

        //

        //
        release: function () {

            if (mouseCaptureConfig) {

                if (mouseCaptureConfig.released) {
                    //
                    // Let the client know that their 'mouse capture' has been released.
                    //
                    mouseCaptureConfig.released();
                }

                mouseCaptureConfig = null;

//

From the documentation it looks like you need to declare all dependency injections in string array.

从文档来看,似乎需要在字符串数组中声明所有依赖项注入。

There are other ways but normally I would do it like this:

还有其他的方法,但通常我会这样做:

controller: ['$scope', '$element', '$attrs', 'mouseCapture',
  function($scope, $element, $attrs, mouseCapture) {
    ...
  }
]

One of the reason we do this is because when we try to minify this js file, variable names would be reduced to one or 2 characters, and DI needs the exact name to find the services. By declaring DI in a string array, angular can match services with their minified variable name. For this reason, the string array and the function arguments need EXACT MATCHING in number and order.

我们这样做的原因之一是,当我们试图缩小这个js文件时,变量名将减少到一个或两个字符,而DI需要确切的名称来查找服务。通过在字符串数组中声明DI, angle可以将服务与其缩小的变量名匹配。因此,字符串数组和函数参数需要在数量和顺序上进行精确匹配。

If you are following John Papa's Angular style guide, you should do it like this:

如果你遵循约翰·爸爸的棱角分明的风格指南,你应该这样做:

controller: MouseCaptureController,
...

MouseCaptureController.$inject = ['$scope', '$element', '$attrs', 'mouseCapture'];

function MouseCaptureController($scope, $element, $attrs, mouseCapture) {
  ...
}

的代码表示:

$injector:strictdi

$注射器:strictdi

There is an error with the dependency injection In the documentation for this error:

在文档中有一个关于这个错误的依赖注入的错误:

Strict mode throws an error whenever a service tries to use implicit annotations

当服务试图使用隐式注解时,严格模式会抛出错误

You should try to switching to:

你应尝试转到:

.factory('mouseCapture', ['$rootScope', function ($rootScope) {...}]);

syntax, whenever in strict mode.

语法,在严格模式下。
