[英]How to call react js function or pass arguments to react js from normal JS/HTML?
I am developing a web app where I need to do certain things in React JS. 我正在开发一个Web应用程序,我需要在React JS中做某些事情。 I have written the react js code. 我已经写了react js代码。
But I want it to be called only when a button is clicked. 但我希望仅在单击按钮时才能调用它。 How to do this? 这个怎么做?
I read the tutorial but still couldn't figure out this. 我阅读了本教程,但仍然无法弄清楚。
Please help me. 请帮我。 Struck for 2 hours. 打了两个小时。
If you wish to render a <ReactComponent/>
at <div id="mountPoint"></div>
using a button click and wish to pass an Object data
to React, this should solve your problem. 如果您希望通过单击按钮在<div id="mountPoint"></div>
<ReactComponent/>
处呈现<ReactComponent/>
并希望将对象data
传递给React,这应该可以解决您的问题。
The button below is not rendered using React. 以下按钮未使用React呈现。 There must also be a mount point specified beforehand where React will mount the <ReactComponent/>
: 还必须事先指定一个安装点,React将在该安装点安装<ReactComponent/>
:
<button onclick=ReactRender()> Render React </button>
<div id="mountPoint"></div>
The button calls a function ReactRender()
which does all the rendering. 该按钮调用一个函数ReactRender()
来完成所有渲染。
//Now to render React
var ReactRender = function(){
// data is an Object which you wish to pass to React
ReactDOM.render(<ReactComponent data={data}></ReactComponent>, mountPoint);
}
The data
you have passed from outside React will be available as this.props.data
inside ReactComponent
. 您从React外部传递的data
将在this.props.data
内部以ReactComponent
。
