问题:
在
styles.inputInput
我已经使用 material-ui 的theme.transition.create
创建了一个转换,问题是,如果宽度是固定的数字工作正常,如果我将百分比传递给它,组件只有固定宽度,根本没有扩展或过渡。还有一个问题是,如果 searchBar 的宽度超过它的父级可以容纳的宽度,它不会将“PlaceHolder”推出
Paper
,但会将末尾的按钮推出Paper
元素及其自身会将自身推过右边界。
我使用了 material-ui 中的 theme.create.transitions()
,但请建议任何仅使用 CSS 的解决方案。

最佳答案
主要问题是您的“searchBar”div
限制了您输入的“100%”的含义。关键是对整个搜索输入使用 InputBase
,这意味着对搜索图标使用 startAdornment
:
<div className={classes.searchBar}>
<InputBase
startAdornment={<SearchIcon />}
placeholder="Search"
classes={{
root: classes.inputRoot,
focused: classes.inputFocused
}}
/>
</div>
然后对样式进行了一些必要的调整(将一些样式从 searchBar
移动到 inputRoot
以及从 inputInput
移动到 inputRoot
):
searchBar: {
width: "100%",
display: "flex",
flexDirection: "row"
},
inputRoot: {
marginTop: theme.spacing.unit,
marginBottom: theme.spacing.unit,
marginLeft: theme.spacing.unit,
marginRight: theme.spacing.unit * 5,
borderRadius: theme.shape.borderRadius * 0.5,
backgroundColor: theme.palette.secondary.main,
color: theme.palette.primary.main,
transition: theme.transitions.create("width"),
width: "auto",
[theme.breakpoints.up("sm")]: {
width: "25%" //change it to 250(number)
},
"&$inputFocused": {
[theme.breakpoints.up("sm")]: {
width: "100%" //change it to 1000(number), it will work fine, but I need percentages.
}
}
},
inputFocused: {},
这是对沙箱的有效修改:
关于javascript - 将 css transition 应用于元素的宽度,使其覆盖其容器 div [ReactJS] 的 100% 宽度,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/54957126/
