我有以下JavaScript代码和内联CSS。
var container = display.getContainer();
container.style.cssText = 'width:100%;height:100%;z-index:100;object-fit: contain;';
document.body.appendChild(container);
我想将内联CSS移至style.css中的以下类
.containerClass {
width:100%;
height:100%;
z-index:100;
object-fit: contain;
}
我尝试了以下方法:
container.addClass('containerClass');
我无法正确表达我的问题,因此难以找到我要的精确解决方案。
进一步-我该如何告诉JavaScript文件.containerClass
的位置?

在style.css中,定义react-native-sectioned-multi-select
的属性。
style.css:
import React, { Component } from 'react';
import { View } from 'react-native';
import { Container, Body, Header, Title, Content, List, ListItem, Text, Left, Right, Icon, Footer, FooterTab, Button} from 'native-base';
import SectionedMultiSelect from 'react-native-sectioned-multi-select';
var items = [];
class Home extends Component {
constructor(){
super();
this.state = {
data: [],
selectedItems: []
};
}
getData(){
return fetch('https://test.com/php.php')
.then((response) => response.json())
.then((responseJson) => {
console.log(JSON.stringify(responseJson.result));
this.setState({data:responseJson.result});
//alert(responseJson.result[1].name);
//return responseJson.result[1].name;
})
.catch((error) => {
console.error(error);
});
}
componentDidMount(){
this.getData();
this.state.data.map((cardData, i) =>{
items.push({
name: cardData.name,
id: cardData.ver
});
});
}
onSelectedItemsChange = selectedItems => {
this.setState({ selectedItems });
};
render() {
return (
<View>
<SectionedMultiSelect
items={items}
uniqueKey='id'
selectText='Choose some things...'
showDropDowns={false}
readOnlyHeadings={false}
onSelectedItemsChange={this.onSelectedItemsChange}
selectedItems={this.state.selectedItems}
/>
</View>
);
}
}
要添加此样式时,只需将该类添加到要使用javascript的元素中即可。 Javascript:
result [{
name: xxxxxx,
ver: xxxxx
}]

注意: Internet Explorer 9不支持 classList 属性。
以下代码将在所有浏览器中运行-
function addClass() {
var element, name, arr;
element = document.getElementById("container");
name = "mystyle";
arr = element.className.split(" ");
if (arr.indexOf(name) == -1) {
element.className += " " + name;
}
}
.mystyle {
background-color: black;
color: white;
}
div {
margin-top: 20px;
width: 100%;
padding: 25px;
font-size: 25px;
box-sizing: border-box;
border: 1px solid #000;
}
<p>Click the "Add Class" button to add the "mystyle" class to the container element:</p>
<button onclick="addClass()">Add Class</button>
<div id="container">This is a DIV element.</div>
