javascript - The relationship between Angular controller control domain and native js-PHP Chinese Network Q&A

I wrote a piece of js code and found that the native js written in the controller did not work. The error message showed that the function could not be found. The code is as follows:

app.controller('orderFormCtrl', function ($scope, $http) { // 订单备注 $scope.food_remarks = []; // 订单详情数组 $scope.forms_detail = []; $scope.food_detail = []; // 查询订单详情 $scope.search_detail = function(index){ $scope.forms_detail = $scope.food_forms[index]; $scope.food_remarks = $scope.food_forms[index].remarks; console.log($scope.forms_detail); // var form_num = $scope.forms_detail.order_number; $scope.food_detail = $scope.food_forms[index].food_detail; // console.log($scope.food_detail); for (var i = 0; i < $scope.food_detail.length; i++) { for (var j = 0; j < $scope.food_menu.length; j++) { if ($scope.food_detail[i].id == $scope.food_menu[j].id) { $scope.food_detail[i].name = $scope.food_menu[j].name; $scope.food_detail[i].price = $scope.food_menu[j].price; $scope.food_detail[i].img = $scope.food_menu[j].img; } } } }; //计算总价 $scope.allSum=function(){ var allPrice = 0; for(var i= 0;i<$scope.food_detail.length;i++){ allPrice+=$scope.food_detail[i].price*$scope.food_detail[i].num; // console.log(allPrice); } return allPrice; }; 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", "orderNo": "20122157481315", "shop":"XX连锁", "total":25.10,"totalCount":6, "goodsList":[ {"name":"菜心(无公害食品)", "price":5.00, "count":2, "total":10.08}, {"name":"菜心(无公害食品)", "price":5.00, "count":2, "total":10.02}, {"name":"旺菜", "price":4.50, "count":1, "total":4.50}, {"name":"黄心番薯(有机食品)", "price":4.50, "count":1, "total":4.50} ] } var hPos=10,//小票上边距 pageWidth=580,//小票宽度 rowHeight=15,//小票行距 //获取控件对象 LODOP=getLodop(document.getElementById('LODOP_OB'),document.getElementById('LODOP_EM')); //初始化 LODOP.PRINT_INIT("打印控件功能演示_Lodop功能_名片"); //添加小票标题文本 LODOP.ADD_PRINT_TEXT(hPos,30,pageWidth,rowHeight,json.title); //上边距往下移 hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"姓名:"); LODOP.ADD_PRINT_TEXT(hPos,30,pageWidth,rowHeight,json.name); //hPos+=rowHeight; //电话不换行 LODOP.ADD_PRINT_TEXT(hPos,70,pageWidth,rowHeight,"电话:"); LODOP.ADD_PRINT_TEXT(hPos,100,pageWidth,rowHeight,json.phone); hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"下单时间:"); LODOP.ADD_PRINT_TEXT(hPos,60,pageWidth,rowHeight,json.orderTime); hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"订单编号:"); LODOP.ADD_PRINT_TEXT(hPos,60,pageWidth,rowHeight,json.orderNo); hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"取货门店:"); LODOP.ADD_PRINT_TEXT(hPos,60,pageWidth,rowHeight,json.shop); hPos+=rowHeight; LODOP.ADD_PRINT_LINE(hPos,2, hPos, pageWidth,2, 1); hPos+=5; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"商品名称"); LODOP.ADD_PRINT_TEXT(hPos,70,pageWidth,rowHeight,"单价"); LODOP.ADD_PRINT_TEXT(hPos,110,pageWidth,rowHeight,"数量"); LODOP.ADD_PRINT_TEXT(hPos,140,pageWidth,rowHeight,"小计"); hPos+=rowHeight; //遍历json的商品数组 for(var i=0;i


      Later I discovered that if I put the native js outside the control domain of the controller, I can find the function and run it normally (as shown below)
      app.controller('orderFormCtrl', function ($scope, $http) { // 订单备注 $scope.food_remarks = []; // 订单详情数组 $scope.forms_detail = []; $scope.food_detail = []; // 查询订单详情 $scope.search_detail = function(index){ $scope.forms_detail = $scope.food_forms[index]; $scope.food_remarks = $scope.food_forms[index].remarks; console.log($scope.forms_detail); // var form_num = $scope.forms_detail.order_number; $scope.food_detail = $scope.food_forms[index].food_detail; // console.log($scope.food_detail); for (var i = 0; i < $scope.food_detail.length; i++) { for (var j = 0; j < $scope.food_menu.length; j++) { if ($scope.food_detail[i].id == $scope.food_menu[j].id) { $scope.food_detail[i].name = $scope.food_menu[j].name; $scope.food_detail[i].price = $scope.food_menu[j].price; $scope.food_detail[i].img = $scope.food_menu[j].img; } } } }; //计算总价 $scope.allSum=function(){ var allPrice = 0; for(var i= 0;i<$scope.food_detail.length;i++){ allPrice+=$scope.food_detail[i].price*$scope.food_detail[i].num; // console.log(allPrice); } return allPrice; }; }); //controller控制域外 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", "orderNo": "20122157481315", "shop":"XX连锁", "total":25.10,"totalCount":6, "goodsList":[ {"name":"菜心(无公害食品)", "price":5.00, "count":2, "total":10.08}, {"name":"菜心(无公害食品)", "price":5.00, "count":2, "total":10.02}, {"name":"旺菜", "price":4.50, "count":1, "total":4.50}, {"name":"黄心番薯(有机食品)", "price":4.50, "count":1, "total":4.50} ] } var hPos=10,//小票上边距 pageWidth=580,//小票宽度 rowHeight=15,//小票行距 //获取控件对象 LODOP=getLodop(document.getElementById('LODOP_OB'),document.getElementById('LODOP_EM')); //初始化 LODOP.PRINT_INIT("打印控件功能演示_Lodop功能_名片"); //添加小票标题文本 LODOP.ADD_PRINT_TEXT(hPos,30,pageWidth,rowHeight,json.title); //上边距往下移 hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"姓名:"); LODOP.ADD_PRINT_TEXT(hPos,30,pageWidth,rowHeight,json.name); //hPos+=rowHeight; //电话不换行 LODOP.ADD_PRINT_TEXT(hPos,70,pageWidth,rowHeight,"电话:"); LODOP.ADD_PRINT_TEXT(hPos,100,pageWidth,rowHeight,json.phone); hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"下单时间:"); LODOP.ADD_PRINT_TEXT(hPos,60,pageWidth,rowHeight,json.orderTime); hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"订单编号:"); LODOP.ADD_PRINT_TEXT(hPos,60,pageWidth,rowHeight,json.orderNo); hPos+=rowHeight; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"取货门店:"); LODOP.ADD_PRINT_TEXT(hPos,60,pageWidth,rowHeight,json.shop); hPos+=rowHeight; LODOP.ADD_PRINT_LINE(hPos,2, hPos, pageWidth,2, 1); hPos+=5; LODOP.ADD_PRINT_TEXT(hPos,1,pageWidth,rowHeight,"商品名称"); LODOP.ADD_PRINT_TEXT(hPos,70,pageWidth,rowHeight,"单价"); LODOP.ADD_PRINT_TEXT(hPos,110,pageWidth,rowHeight,"数量"); LODOP.ADD_PRINT_TEXT(hPos,140,pageWidth,rowHeight,"小计"); hPos+=rowHeight; //遍历json的商品数组 for(var i=0;i

      
      What is the reason for this? In a project I worked on before, it was possible to write native js in the controller. I don’t know why it can’t be used this time
