我正在单击按钮时实现模态窗口。
我的问题是单击按钮时显示对话框组件的最佳方式是什么。我正在尝试设置 CSS 的var modal
,这给了我错误。./src/components/btn-root.js
Line 14: 'modal' is not defined no-undef
我有以下按钮组件,onclick 将在其上显示模态窗口组件。
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import ModelDialog from './modal-dialog';
export default class ButtonRoot extends Component{
render(){
// Get the button that opens the modal
var btn = document.getElementById("base-btn");
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
return (
<button id='base-btn'>Order Credit</button>
);
}
}
以下是模型对话框组件
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
export default class ModelDialog extends Component {
render(){
// Get the modal
var modal = document.getElementById('myModal');
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
return(
<div id="myModal" className="modal">
<div className="modal-content">
<span className="close">×</span>
<div className="order--container">
<p>5 IV's</p>
<p>25 IV's</p>
<p>50 IV's</p>
<p>100 IV's</p>
<p>500 IV's</p>
</div>
<div className="order--form">
<form>
<div className="tc--checkbox">
<input type="checkbox" id="subscribeNews" name="subscribe" value="newsletter" />
<label for="tcs">I accept Terms & Conditions</label>
</div>
<div className="order--btn">
<button type="submit">Order</button>
</div>
</form>
</div>
</div>
</div>
);
}
}
