onmouseover

问题 I'm having an issue with onmouseover and onmouseleave event. This code only works maybe 5% of the time and I don't understand why. Just looking at the console when I hover over the image map. It triggers the onmouseover then the onmouseleave and then onmouseover again. If I comment out the bootstrap modal show and hide then the image just swaps and triggers events normally. I don't know if this is an issue with bootstrap modals or what but I have two call to action buttons on the same page

问题 How do I change an image on hover in JSX I'm trying something like this: <img src={require('../../../common/assets/network-inactive.png')} onMouseOver={this.src = require('../../../common/assets/network.png')} onMouseOut={this.src = require('../../../common/assets/network-inactive.png')} /> 回答1: I will assume you are writing this code in a React component.
