我在定制ItemSelector指令的元素,来自rails服务器的ItemSelector的数据。
这里是haml代码:
.directive-items-selector{ ng_click: "openItemsSelector( $event )" }
.wrapper
%ui_select.ui-select{ ng: { model: "input.model", disabled: "disabled",
change: "itemSelectModelChanged()" },
search_enabled: "{{ options.searchable }}" }
%ui_select_match.ui-select-match{ items_selector_match: '',
placeholder: "{{ input.placeholder }}",
allow_clear: "{{ options.clearable }}",
title: "{{ $select.selected.label }}" }
%i.fa{ ng_class: 'icon' }
{{ $select.selected.label }}
%i.archived.fa.fa-archive{ ng_if: '$select.selected.object.is_archived' }
%span.archived{ translate: 'archived.yes' }
%ui_select_choices.ui-select-choices{ repeat: "item.id as item in input.filteredItems track by item.id",
refresh: "reloadItems( $select.search )",
refresh_delay: '{{ input.filterDelay }}' }
.item{ ng_attr_title: "{{ ::item.label }}" }
.item-label {{ ::item.label }}
%small.item-details {{ ::item.details }}
.items-selector-actions
%a.pointer.action{ ng: { if: 'linkToModal', click: 'openDetails()', disabled: "!model" }}
{{ 'btn.details' | translate }}
%a.pointer.action{ ng: { if: 'createButton && klassName && !disabled', click: 'createItem()' }}
{{ 'btn.new' | translate }}
我测试所选对象是否存档:
$ select.selected.object.is_archived
现在我添加一个图标和一个小文本告诉用户所选的这个对象已存档,我想要的是更改它并添加 text-decoration:line-through red; 就是这样的:
如何添加css类取决于$ select.selected.object.is_archived值
答案 0 :(得分:1)
Ng-class接受object,其中key是你的类,value是条件,当它被应用时:
ng-class="{'desiredClass': $select.selected.object.is_archived}"
或另一种解决方案是使用三元运算符:
ng-class="$select.selected.object.is_archived ? 'desiredClass' : ''"
在HAML中,通过各种用法:
%div{'ng-class': "{'desiredClass': condition === true}"}
%div{'ng_class': "{'desiredClass': condition === true}"}
%div{'ng': {'class': "{'desiredClass': condition === true}"}}
