我生成了以下四个按钮,但前两个按钮(“更多”按钮)不起作用。
这是代码: BuildControls.js
import React from 'react';
import BuildControl from './BuildControl/BuildControl';
import classes from './BuildControls.css';
const controls = [
{label:'Salad', type:'salad'},
{label:'Bacon', type:'bacon'},
{label:'Cheese', type:'cheese'},
{label:'Meat', type:'meat'}
]
const buildControls =(props)=>(
<div className={classes.BuildControls}>
<p>Current Price: <strong> {props.price} </strong> BDT</p>
{controls.map(ctrl => (
<BuildControl
label ={ctrl.label}
key={ctrl.label}
addIngredient={()=>props.addIngredients(ctrl.type)}
removeIngredient={()=>props.removeIngredient(ctrl.type)}
disabled ={props.disabled[ctrl.type]}
/>
)
)}
<button
disabled={!props.purchaseAble}
className={classes.OrderButton}
onClick ={props.ordered}> ORDER NOW</button>
</div>
);
export default buildControls;
BuildControl.js
import React from 'react';
import classes from './BuildControl.css';
const builControl =(props)=>(
<div className={classes.BuildControl}>
<div className={classes.Label}> {props.label}</div>
<button className={classes.Less} onClick={props.removeIngredient} disabled ={props.disabled}> Less</button>
<button className={classes.More} onClick={props.addIngredient}> More</button>
</div>
);
export default builControl;
因为所有按钮都是由循环问题生成的,所以所有按钮都应该相同。最后两个按钮正常工作,但前两个按钮不工作。它杀死了我的一天。我不知道如何调试,因为我是React JS中的新手。有帮助吗?
更新:
当我从{classes.BuildControls}
中删除<div className={classes.BuildControls}>
时,它可以正常工作。这是CSS:
.BuildControls {
width: 100%;
background-color: #CF8F2E;
display: flex;
flex-flow: column;
align-items: center;
box-shadow: 0 2px 1px #ccc;
margin: auto;
padding: 10px 0;
}
.OrderButton {
background-color: #DAD735;
outline: none;
cursor: pointer;
border: 1px solid #966909;
color: #966909;
font-family: inherit;
font-size: 1.2em;
padding: 15px 30px;
box-shadow: 2px 2px 2px #966909;
}
.OrderButton:hover, .OrderButton:active {
background-color: #A0DB41;
border: 1px solid #966909;
color: #966909;
}
.OrderButton:disabled {
background-color: #C7C6C6;
cursor: not-allowed;
border: 1px solid #ccc;
color: #888888;
}
.OrderButton:not(:disabled) {
animation: enable 0.3s linear;
}
@keyframes enable {
0% {
transform: scale(1);
}
60% {
transform: scale(1.1);
}
100% {
transform: scale(1);
}
}
奇怪! CSS导致点击事件的问题。我的代码有什么问题?
答案 0 :(得分:0)
没有看到完整的代码,我想nums[nums.length - 1];
中的addIngredients
应该是addIngredient
:
buildControls
如果不是那样,请发布const buildControls =(props)=>(
<div className={classes.BuildControls}>
<p>Current Price: <strong> {props.price} </strong> BDT</p>
{controls.map(ctrl => (
<BuildControl
label ={ctrl.label}
key={ctrl.label}
addIngredient={()=>props.addIngredients(ctrl.type)}
// typo here -------------------------^
和addIngredient
方法,包括它们的定义位置和传递方式。
