我試圖創建一個性別選擇視圖,有男性,女性和其他(caitlyn jenner類的東西)。Angular 2 - ngModel不檢查複選框

我現在有是這樣的:

enter image description here

有SVG旁邊的複選框的標籤(複選框將被隱藏在生產,現在可以看到在plunkr用於調試目的)

但當我點擊「女性」時,它會將焦點改爲複選框而不是檢查它。

代碼:

CSS

svg { 
    width: 15px; height: 15px; 

    border: 2px solid #a13b4a; 
} 
label { 
    display: inline-block; 
    padding-left: 1.5em; 
    position: relative; 
    cursor: pointer; 
    color: black; 

} 
input[type="checkbox"] { 
    opacity: 0; 
    width: 15px; 
    height: 15px; 
} 
label svg path { 
    transition: stroke-dashoffset .4s linear; 
} 
input[type="checkbox"]:checked ~ label svg path { 
    stroke-dashoffset: 0; 
} 
input[type="checkbox"]:checked ~ label { 
    color: #a13b4a; 
}

您的實施有兩個問題。

  1. 這裏您不想使用[(ngModel)],因爲您正在更新控制器的值。只需將狀態反映到[checked]指令
  2. 複選框的狀態您不希望在此使用「for」屬性,因爲您已經在標籤上定義了點擊。這將觸發2次點擊,而不是一個(從「的」屬性1,1從(click)事件)

我更新了plunker從一個工作示例
