Angular ui-select 标记在模糊时丢失文本输入 [英] Angular ui-select tagging lose text input on blur

问题描述

情况

大家好！我正在为我的应用程序使用 Angular ui-select 以便从数据库中选择用户.如果用户不在列表中，则可以使用标记来输入新条目.

Hello guys! I am using Angular ui-select for my app in order to select users from a database. Using Tagging is possible to enter a new entry in the event the user is not present in the list.

通过输入名称并按 ENTER 或 TAB，新条目将保存为新标签.

By writing the name and pressing ENTER or TAB the new entry is saved as a new tag.

除了一件小事外，一切正常:如果我用鼠标聚焦，我会丢失输入的内容，这对用户来说不太友好.

Everything is working fine except one little thing: if i focus out with the mouse i lose the input i have entered, and this is not quite user-friendly.

代码

<h3>Array of objects</h3>
<ui-select multiple tagging tagging-label="new tag" ng-model="multipleDemo.selectedPeople" theme="select2" ng-disabled="disabled" style="width: 800px;">
  <ui-select-match placeholder="Select person...">{{$item.name}} &lt;{{$item.email}}&gt;</ui-select-match>
  <ui-select-choices repeat="person in people | propsFilter: {name: $select.search, age: $select.search}">
    <div ng-bind-html="person.name | highlight: $select.search"></div>
    <small>
      email: {{person.email}}
      age: <span ng-bind-html="''+person.age | highlight: $select.search"></span>
    </small>
  </ui-select-choices>
</ui-select>
<p>Selected: {{multipleDemo.selectedPeople}}</p>

问题

如何将输入文本保存为新标签，不仅可以通过按 ENTER 键，还可以通过鼠标聚焦?

How can i manage to save the input text as a new tag, not only by pressing ENTER, but also by focusing out with the mouse?

非常感谢！

推荐答案

只需创建一个指令.这将处理选项卡外的点击并输入.

Just create a directive. This handles the click outside tab and enter.

angular.module('module')
.directive('tagOnBlur', function($timeout) {
  return {
    require: 'uiSelect',
    link: function(scope, elm, attrs, ctrl) {

        scope.isTab = false;

        ctrl.searchInput.bind("keydown keypress", function (event) {
            if(event.which === 9 || event.which === 13) {
                event.preventDefault();
                scope.isTab = true;
            }
        });

        ctrl.bind('click', function (event) {
            scope.isTab = true;
        });

        ctrl.searchInput.on('blur', function() {
            if (scope.isTab){
                scope.isTab = false;
                return;
            }
            if ((ctrl.items.length > 0 || ctrl.tagging.isActivated)) {
                $timeout(function() {
                    ctrl.searchInput.triggerHandler('tagged');
                    var newItem = ctrl.search;
                    if ( ctrl.tagging.fct ) {
                        newItem = ctrl.tagging.fct( newItem );
                    }
                    if (newItem) ctrl.select(newItem, true);
                });
            }
        });
    }
  };
});
