我正在尝试创建一个性别选择 View ,有男性、女性和其他(caitlyn jenner 之类的东西)。
我目前拥有的是:
在复选框的标签旁边有 SVG(复选框将在生产中隐藏,现在在 plunkr 中可见以用于调试目的)
但是当我点击“女性”时,它会将焦点更改为复选框而不是选中它。

代码:
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;
}

最佳答案
您的实现存在两个问题。
- 您不想在此处使用
[(ngModel)]
,因为您正在更新 Controller 中的值。只需使用[checked]
指令将状态反射(reflect)到复选框 - 您不想在这里使用“for”属性,因为您已经在标签上定义了点击。这将触发 2 次点击而不是一次(1 次来自“for”属性,1 次来自
(click)
事件)
我用一个工作示例更新了你的 plunker
关于Angular 2 - ngModel 不检查复选框,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/40152159/
