angularjs - Angular-material - Change separator in md-select multiple option

Question

I have an md-select in my form with multiple options (same as demo in Angular Material site). It shows a comma separated list of selected options in its input field. Is there any way to change separator? (for example change comma to star or another UTF-8 character).

Answer 1

你可以用纯 CSS 做一些事情。您应该使用隐藏逗号visibility: collapse，然后，您可以添加带有:after或:before伪元素的 Unicode 图标。

HTML

<md-select class="my-select" ng-model="vm.selectedItem" multiple>
  <md-option ng-value="item.id" ng-repeat="item in vm.items">{{ item.name }}</md-option>
</md-select>

CSS

.my-select[multiple] .md-select-value span:first-child {
  visibility: collapse;
}

.my-select[multiple] .md-select-value .md-text {
  display: inline-block !important;
  visibility: visible;
}

.my-select[multiple] .md-select-value .md-text:not(:last-child):after {
  content: '\2605'; /* star */
  margin: 0 -5px 0 5px;
}
