我尝试使用javascript动态包含react组件,即用户可以点击" Add Place"并将表单添加到页面中。此表单包含使用material-ui自动完成组件的反应组件。
以下是点击按钮时动态添加的表单代码:
<div class="grid-x grid-margin-x grid-margin-y grid-padding-x grid-padding-y align-center">
<div class="cell medium-6">
<div class="field">
<%= f.label :activity_place %><br/>
<%= react_component("PlaceSearch", {}, {prerender: true}) %>
</div>
</div>
<div class="cell medium-6">
<div class="field">
<%= f.label :activity_time %><br/>
<%= f.select(:activity_time, Constants::ACTIVITY_TIMES) %>
</div>
</div>
</div>
以下是组件的代码(不包括导入):
class PlaceSearch extends React.Component {
state = {
checked: false,
dataSource: [
{
text: 'text-value1',
value: (
<MenuItem
primaryText="text-value1"
secondaryText="☺"
/>
),
},
{
text: 'text-value2',
value: (
<MenuItem
primaryText="text-value2"
secondaryText="☺"
/>
),
},
]
}
render () {
return (
<MuiThemeProvider muiTheme={getMuiTheme({userAgent: (typeof navigator !== 'undefined' && navigator.userAgent) || 'all' })}>
<div>
<AutoComplete
hintText="text-value data"
filter={AutoComplete.noFilter}
dataSource={this.state.dataSource}
/>
</div>
</MuiThemeProvider>
);
}
}
export default PlaceSearch
这个例子我选择了材料-ui的文档。
除反应成分外,一切正常。如果我尝试在动态添加的表单之外的其他地方添加react组件包含代码,它将按预期工作。
我在不同的论坛上搜索了关于材料-ui和rails的问题,但找不到解决这个问题的方法。

您应该将状态声明放在构造函数中:
class PlaceSearch extends React.Component {
constructor() {
super();
this.state = {
checked: false,
dataSource: [
{
text: 'text-value1',
value: (
<MenuItem
primaryText="text-value1"
secondaryText="☺"
/>
),
},
{
text: 'text-value2',
value: (
<MenuItem
primaryText="text-value2"
secondaryText="☺"
/>
),
}]
}
}
render () {
return (
<MuiThemeProvider muiTheme={getMuiTheme({userAgent: (typeof navigator !== 'undefined' && navigator.userAgent) || 'all' })}>
<div>
<AutoComplete
hintText="text-value data"
filter={AutoComplete.noFilter}
dataSource={this.state.dataSource}
/>
</div>
</MuiThemeProvider>
); } }
export default PlaceSearch
如果这对您有用,这就是原因:SO Post

最后通过添加手动组件安装代码,即 ReactRailsUJS.mountComponents(),如react-rails gem的github doc中所述。没有对组件JS文件进行任何更改,只对包含它的表单进行了更改。工作代码如下:
<div class="grid-x grid-margin-x grid-margin-y grid-padding-x grid-padding-y align-center">
<div class="cell medium-6">
<div class="field">
<%= f.label :activity_place %><br/>
<%= react_component("PlaceSearch", {}, {prerender: true}) %>
</div>
</div>
<div class="cell medium-6">
<div class="field">
<%= f.label :activity_time %><br/>
<%= f.select(:activity_time, Constants::ACTIVITY_TIMES, include_blank: true) %>
</div>
</div>
</div>
<script>
ReactRailsUJS.mountComponents()
</script>
