Angularjs ui选择已禁用搜索的占位符文本

我正在使用AngularUI选择Selectize主题。我想禁用搜索，但想显示占位符文本，以便用户知道此选择字段的用途。 我尝试将selectize/match.tpl.html修改为

<div ng-hide=\"($select.open || $select.isEmpty())\" class=\"ui-select-match\" ng-transclude=\"\">{{$select.placeholder}}</div>

再次在控制器中

 angular.element(angular.element($element[0])).find('span').text(scope.name)

---

我为此编写了一个包装器指令，更新了匹配模板，如下所示，并使用search enable=false

$templateCache.putselectize/match.tpl.html

使用包装器指令中的链接，我正在用palceholder文本更新上述模板

  angular.element(angular.element($element[0])).find('span').text($scope.placeholder)

在包装器指令中使用控制器，更新所选字符串

 angular.element(angular.element($element[0])).find('span').text(scope.name)

---

我修改了select.tpl.html，如下所示

$templateCache.put("selectize/select.tpl.html","<div class=\"selectize-control single\"><div class=\"selectize-input\" ng-class=\"{\'focus\': $select.open, \'disabled\': $select.disabled, \'selectize-focus\' : $select.focus}\" ng-click=\"$select.activate()\"><div class=\"ui-select-match\"></div><div class=\"ui-select-placeholder\" ng-hide=\"!$select.isEmpty()\">{{$select.placeholder}}</div><input type=\"text\" autocomplete=\"off\"  tabindex=\"-1\" class=\"ui-select-search ui-select-toggle\" ng-click=\"$select.toggle($event)\" placeholder=\"{{$select.placeholder}}\" readonly ng-model=\"$select.search\" ng-hide=\"!$select.searchEnabled || ($select.selected && !$select.open)\" ng-disabled=\"$select.disabled\"></div><div class=\"ui-select-choices\"></div></div>");}]);

当所选内容为空时，将添加带有占位符的div。否则它将被隐藏

 angular.element(angular.element($element[0])).find('span').text(scope.name)

$templateCache.put("selectize/select.tpl.html","<div class=\"selectize-control single\"><div class=\"selectize-input\" ng-class=\"{\'focus\': $select.open, \'disabled\': $select.disabled, \'selectize-focus\' : $select.focus}\" ng-click=\"$select.activate()\"><div class=\"ui-select-match\"></div><div class=\"ui-select-placeholder\" ng-hide=\"!$select.isEmpty()\">{{$select.placeholder}}</div><input type=\"text\" autocomplete=\"off\"  tabindex=\"-1\" class=\"ui-select-search ui-select-toggle\" ng-click=\"$select.toggle($event)\" placeholder=\"{{$select.placeholder}}\" readonly ng-model=\"$select.search\" ng-hide=\"!$select.searchEnabled || ($select.selected && !$select.open)\" ng-disabled=\"$select.disabled\"></div><div class=\"ui-select-choices\"></div></div>");}]);
