有没有办法降低 onMouseLeave 或 onMouseOut 触发事件的灵敏度。因为我想将它们应用于弹出对话框,除非它们在鼠标悬停在文本(即 div 标签)上时一直在触发,只有当我完全冷静下来时它们才不会触发并且弹出对话框还可以.功能显然有效,但鼠标事件的敏感性太高。

这是我最重要的代码部分:

<div className="titleUnderLogo">
                <br /> <br />
                {applicationDataDefinition.map((item) =>
                    <div className="titleUnderLogo" onMouseOver = {this.mouseOver} onMouseLeave={this.mouseLeave} /* Tried with this also onMouseOut={this.mouseOut} */  >

                        {item.name} {item.release} - {item.level} - {item.location}
                    </div>
                )}
                <br /> <br />
                <Container >
                    <Dialog
                        displayed = {showDialog}
                        title="Product name"
                        modal={true}
                        layout="center"
                        defaultFocus="#ok"
                        ui="titleUnderLogoCls"
                        closeAction="hide"
                        maskTapHandler={this.mouseTapped}
                        onHide={() => this.setState({ showDialog: false })}
                    >
                        {applicationDataDefinition.map((item) =>
                            <div>
                                <table>
                                    <tr>
                                        <td> <b> Product name: </b> </td>
                                        <td> {item.name} </td>
                                    </tr>
                                    <tr>
                                        <td> <b> Release: </b> </td>
                                        <td>  {item.release}  </td>
                                    </tr>
                                    <tr>
                                        <td> <b> Last fix installed: </b> </td>
                                        <td> {item.lastFix}  </td>
                                    </tr>
                                    <tr>
                                        <td> <b> Environment: </b> </td>
                                        <td> {item.level} </td>
                                    </tr>
                                        <td> <b> Location: </b>  </td>
                                        <td> {item.location} </td>
                                </table>
                            </div>
                        )}
                    </Dialog>
                </Container>
</div>

最佳答案

您可以使用 lodash.throttle 限制事件

element.addEventListener('mouseout', _.throttle(callback, 100)); // 100 miliseconds
callback 是你在 mouseout 上做的函数

编辑

好吧,我不明白 react ,但正如我所见,一定是这样的
this.mouseOver//似乎是您的 ViewModel 中的一个方法,所以
mouseOver: _.throttle(() => {
        // do something here or call another function like
        this.yourFunctionFromViewModelForMouseOver();
},100)
onMouseLeave={this.mouseLeave} 也一样
mouseLeave: _.throttle(() => {
            // do something here or call another function like
            this.yourFunctionFromViewModelForMouseLeave();
    },100)
