文本框中的数据如何调用 Angular 函数？这是我的代码

html

<!DOCTYPE html!>
<html xmlns:ng="http://angularjs.org" data-ng-app="flightSearch" lang="en">
    <head>
        <script src="js/jquery-1.9.1.js"></script>
        <script src="js/jquery-ui.js"></script>

    </head>
    <body> 
        <div data-ng-controller="flightSearchController">

<input type="text" data-ng-model="query" data-ng-change="flightSearch()" placeholder="e.g RGN>MDL, KAW>RGN"  id="targetTextField"  />

<input id="options3" type="text" style="display:none;"/>



<select id="options">
  <option value="From" selected>From</option>
  <option value="RGN" ng-click="flightSearch()">RGN</option>
  <option value="NYU" ng-click="flightSearch()">NYU</option>
  <option value="MDL" ng-click="flightSearch()">MDl</option>
  <option value="HEH" ng-click="flightSearch()">HEH</option>
</select>

<select id="options2">
  <option value="To" selected>To</option>
  <option value=">RGN" ng-click="flightSearch()">RGN</option>
  <option value=">NYU" ng-click="flightSearch()">NYU</option>
  <option value=">MDL" ng-click="flightSearch()">MDl</option>
  <option value=">HEH" ng-click="flightSearch()">HEH</option>
</select>

            <ul>
                <li data-ng-repeat="route in filteredItems"> 
                    <div data-ng-bind-html="route.displayRoute"></div>
                </li>
            </ul>

        </div>
    </body>

js

<script src="js/angular.min.js"></script>

        function buildPaths(route){

            for(var i = 0; i < points.length; i++){
                var from = points[i];
                for(var j = i; j < points.length; j++){
                    var to = points[j];
                    if (from != to){
                        if(paths[from + ">" + to]){

                                paths[from + ">" + to] = [j-i,points.slice(i,j+1).join(">")]
                        }else{

            // Assign the routes. This is unfiltered origintal data (all)
            $scope.routes = dataRoutes;

            // This is filtered list for dispaly
            $scope.filteredItems = $scope.routes;

            // Search/filter function. This updates filteredItems list
            $scope.flightSearch = function(){


                if($scope.query.length > 6){
                    $scope.filteredItems = [];
                    for(var index in $scope.routes){
                        $scope.routes[index]["displayRoute"] = $scope.routes[index]["route"];

                            $scope.filteredItems.push($scope.routes[index]);
                        }
                    }

                        $scope.routes[r]["displayRoute"] = $scope.routes[r]["route"];
                    }

        flightSearch.filter("highlight",function(){
                return function(text){
                        return text;
                }
        });
    </script>
    <script type="text/javascript">
        $(function() {
$("#options").change(function(){
        setTarget()
});
    $("#options2").change(function(){
        setTarget();
});
    $("#options3").change(function(){
        setTarget();
});
    $("#targetTextField").change(function(){
        setTarget();
});
});

function setTarget(){
    var tmp = $("#options").val();
    tmp += $("#options2").val();
    tmp += $("#options3").val();
    $('#targetTextField').val(tmp);
}


    </script>
</html>

当两个选择选项在文本框中插入数据时想要在change.strong文本上调用搜索功能

最佳答案

如果您将 ID 标记附加到与 ng-controller 相同的 DOM 元素，则可以访问 Angular 元素的范围:

DOM:

<div id="mycontroller" ng-controller="mycontroller"></div>

您的 Controller :

function mycontroller($scope) {
   $scope.myfunction = function() {
      //do some stuff here
   }
}

在 jquery 中，你执行此操作，它将访问该 Controller 并调用该函数:

angular.element('#mycontroller').scope().myfunction();

记得打电话

angular.element('#mycontroller').scope().$apply()

如果您更新 myfunction 范围内的函数变量，否则它将无法工作(感谢 @andersh)
