嗨,我还是React的新手,所以我将样式化的组件用于css组件,并按下了以下按钮:
const SummonButton = styled.button`
height: 50px;
border: none;
outline: none;
color: #fff;
background: #111;
cursor: pointer;
position: relative;
z-index: 0;
border-radius: 10px;
font-size: 1.5em;
:before {
content: '';
background: linear-gradient(45deg, #ff0000, #ff7300, #fffb00, #48ff00, #00ffd5, #002bff, #7a00ff, #ff00c8, #ff0000);
position: absolute;
top: -2px;
left:-2px;
background-size: 400%;
z-index: -1;
filter: blur(5px);
width: calc(100% + 4px);
height: calc(100% + 4px);
animation: glowing 20s linear infinite;
opacity: 0;
transition: opacity .3s ease-in-out;
border-radius: 10px;
}
:active {
color: #000
}
:active:after {
background: transparent;
}
:hover:before {
opacity: 1;
}
:after {
z-index: -1;
content: '';
position: absolute;
width: 100%;
height: 100%;
background: #111;
left: 0;
top: 0;
border-radius: 10px;
}
@keyframes glowing {
0% { background-position: 0 0; }
50% { background-position: 400% 0; }
100% { background-position: 0 0; }
}
但是我希望此SummonButton在按下十次后停止运行,这就是为什么我要编写以下行:
<SummonButton onClick={summonAble < 10 ? SummonAction : {backgroundColor: "red"}}>Summon</SummonButton>
summonAble是每次调用SummonAction时计数为+1的状态。现在,在达到10次点击之后,它会停止添加,因此保持为10,但是现在如何在十次点击之后将按钮的背景颜色更改为红色?
答案 0 :(得分:1)
您必须将点击次数存储在某个地方。
const [clicks, setClicks] = React.useState(0);
然后,您必须在SummonButton
上添加一个道具,以确定条件是否满足:
<SummonButton onClick={...} isRed={clicks > 9} />
const SummonButton = styled.button`
background: ${({ isRed }) => isRed ? 'red' : 'black'};
...
`;
注意:请记住在绑定到setClicks
的每个函数调用中调用onClick
函数。
