Angular4_动态启用禁用select

原文出处：/qq_36279445/article/details/82149500

<select class="form-control customSelect" [(ngModel)]="packagingType" [ngClass]="{'disableSelect' : isBulkToteMaterial}" name="packagingType" (change)="packagTypeChange(packagingtype.value)" #packagingtype tabindex="-1"><option *ngFor="let type of packagingTypes" value="{{type.value}}">{{type.key}}</option></select>

css

.disableSelect{ pointer-events: none;}

pointer-events CSS 属性指定在什么情况下 (如果有) 某个特定的图形元素可以成为鼠标事件的 target。

tabindex="-1" 是搞掉键盘按tab 能触发事件的情况

/* Keyword values */pointer-events: auto;pointer-events: none;pointer-events: visiblePainted; /* SVG only */pointer-events: visibleFill; /* SVG only */pointer-events: visibleStroke; /* SVG only */pointer-events: visible; /* SVG only */pointer-events: painted; /* SVG only */pointer-events: fill; /* SVG only */pointer-events: stroke; /* SVG only */pointer-events: all; /* SVG only *//* Global values */pointer-events: inherit;pointer-events: initial;pointer-events: unset;

当此属性未指定时，visiblePainted值的相同特征适用于 SVG 内容。

除了指示该元素不是鼠标事件的目标之外，值none表示鼠标事件“穿透”该元素并且指定该元素“下面”的任何东西。
