我有返回类`<script type="text/javascript">
var validNavigation = false;
function bindDOMEvents() {
$(document).click("a", function () {
validNavigation = true;
});
$(document).on("submit", "form", function () {
validNavigation = true;
});
$(document).bind("click", "input[type=submit]", function () {
validNavigation = true;
});
$(document).bind("click", "button[type=submit]", function () {
validNavigation = true;
});
$(document).bind("click", "radio[type=submit]", function () {
validNavigation = true;
});
$(document).bind("click", "checkbox[type=submit]", function () {
validNavigation = true;
});
$(window).keydown(function (e) {
validNavigation = e.which === 116 ? true : false
});
}
function callServerForBrowserCloseEvent() {
$.ajax({
type: "GET",
url: "@Url.Action("LogOut", "Account")",
contentType: "application/json; charset=utf-8",
dataType: 'JSON',
traditional: true,
async: false
});
}
$(document).ready(function () {
bindDOMEvents();
window.addEventListener("beforeunload", function () {
if (!validNavigation)
callServerForBrowserCloseEvent();
else
validNavigation = false;
});
});
</script>`
的服务函数withFetching：
Fetch我需要另一个类中的调用方法import React from 'react';
import * as axios from 'axios';
const withFetching = url => Component => {
class Fetch extends React.Component {
state = {
data: null,
isLoading: false
};
componentDidMount() {
this.setState({isLoading: true});
}
get = (params) => {
axios.get(url, params)
.then(response => {
this.setState({data: response.data, isLoading: false});
})
.catch(error => {
console.error('%c ERROR', 'color: #FA12D6', error);
});
};
post = data => {}
put = () => {}
render() {
return <Component {...this.state}
{...this.props}
post={this.post}
put={this.put}
delete={this.delete}/>;
}
}
Fetch.displayName = `Fetch(${Component.displayName || Component.name || 'Component'})`;
return Fetch;
};
export default withFetching;
。我正在做类似的事情：
get答案 0 :(得分：0)
我解决了调用CRUD服务方法的问题
import React from 'react';
import WithFetching from './../../../../services/withFetching';
class MyComponent extends React.Component {
state = {};
componentWillMount() {
const {post} = this.props;
post({data:'data'});
}
render() {
return (
...
);
}
}
export default WithFetching('URL')(MyComponent);
我们通过post获得了类方法props，并在组件（componentWillMount）的生命周期中对其进行了调用
