Question

您好我正在努力找出为什么我的指令调用ngChange函数这么慢。没有模板，它的工作速度超快。

这是我的Html 指令模板

  <input type="search" class="search_input artist-job-search-input"
                       placeholder="Search jobs by profession, musical work, role or institution"
                       ng-model="$ctrl.artistSearchModel"
                       ng-change="$ctrl.searchArtistJob()"
                       ng-model-options="{debounce: 500}" select-on-click
                       style="max-width: 55.9vw;"/>

这是 directive.js

app.directive('jobsSearch', function () {

return {
    restrict: 'EA',
    scope: {
        'artistSearchModel': "=",
        'showDropdown': "=",
        'operaticRoleSearchResult': "=",
        'viewAllJobs': "&",
        'musicalWorkSearchResult': "=",
        'institutionSearchResult': "=",
        'changeTypeOfFilter': "&",
        // 'searchFilterOne': "=",
        // 'searchFilterTwo': "=",
        // 'searchFilterThree': "=",
        // 'searchFilterFour': "=",
        // 'searchFilterFive': "=",
        'searchArtistJob': "&",
        'placeOfSearch':"@placeOfSearch",
        'artistFilterSearch':'='
        },
    controller: function () { },
    controllerAs: '$ctrl',
    bindToController: true,
    templateUrl: '/views/profile/directives/job_search.html'
};

}）;

这就是我调用指令Directive call

的地方

<jobs-search artist-search-model="jobDashboard.artistSearchModel" 
          search-artist-job="jobDashboard.searchArtistJob()"
          show-dropdown="jobDashboard.showDropdown"
          operatic-role-Search-result="jobDashboard.operaticRoleSearchResult"
          view-all-jobs="jobDashboard.viewAllJobs(paramsJobs)"
          musical-work-search-result="jobDashboard.musicalWorkSearchResult"
          institution-search-result="jobDashboard.institutionSearchResult"
          change-type-of-filter="jobDashboard.changeArtistJobFilter(params)"
          place-of-search="Jobs"
          artist-filter-search="jobDashboard.artistFilter"

以下代码：

ng-model-options="{debounce: 500}"

告诉角度在完成打字后经过500毫秒后才识别出变化。这是你所指的dealy吗？

指令中的Ng变化太慢了？为什么
