JS Click事件侦听器未按预期触发功能

[英]JS click event listener doesn't trigger function as expected

问题描述

I'm trying to add a click event listener to a div that should then change a css style in another element. 我试图将click事件侦听器添加到div，然后应在另一个元素中更改css样式。 I'm basically trying to make a model window. 我基本上是在尝试制作模型窗口。 When the div/button is clicked, it should change the display property from 'none' to 'border-box'. 单击div /按钮时，应将显示属性从“无”更改为“边框”。 Clicking the div doesn't seem to be having any effect, however. 但是，单击div似乎没有任何效果。 I've tried console logging and nothing shows up there either. 我尝试过控制台日志记录，但那里也没有任何显示。 When I move the div (that is being clicked) and put it in a different part of the HTML doc it seems to work fine tho. 当我移动div（被单击）并将其放在HTML文档的其他部分时，它似乎可以正常工作。 Super confused. 超级困惑。

Border-box doesn't work for the display property. 边框不适用于display属性。 As David mentioned border-box is for box-sizing. 正如David提到的，border-box用于调整大小。 Your JS works fine, I would I've tossed it into a snippet for you: 您的JS工作正常，我会为您提供一个摘要： 

 document.querySelector('#modal-btn').addEventListener('click', function() { console.log('working'); document.querySelector('.modal').style.display = 'block'; }); 
 .modal { display: none; } #modal-btn { cursor: pointer; } 
 <section class="section-background projects-color"> <div class="projects-container container"> <h2 id="projects-section">Projects</h2> <div class="section-divider"></div> <div class="project"> <h3>E-commerce Site</h3> <div class="project-image project-one"></div> <p class="project-description">Lorem ipsum dolor sit amet, pri audire deterruisset ut, mei eu stet diceret pertinacia. Has salutandi mediocritatem te, copiosae disputationi conclusionemque in pro, fugit eleifend argumentum quo et. Sea te quidam instructior complectitur, est vidisse consequat deterruisset ex.</p> <div class="project-icons"> <a href="https://github.com/catspacesuits/new-portfolio"><i class="fab fa-github project-btn"></i></a> <div class="project-btn" id="modal-btn">More details</div> <div class="project-btn">Visit site</div> </div> </div> <div class="modal"></div> <!-- Modal window --> </div> <!-- end of project container --> </section>

I changed display: border-box to display: block and that functions. 我将display：border-box更改为display：block和那个功能。 I also added a console log to show that it is firing when you click the button. 我还添加了一个控制台日志，以显示单击按钮时它正在触发。

相关问题 具有相似行为的第二个元素上的JS click事件不会触发 - JS click event on second element with similar behavior doesn't trigger JS #urls不会在第一次单击时触发该功能 - Js #urls doesn't trigger the function on the first click 我的 function（使用事件监听器）似乎没有给出预期的 output。 我该如何解决？ - My function (using an event listener) doesn't seem to give the expected output. How can I fix it? JS 点击事件监听器只工作一次，而不是预期的 if 语句 - JS click event listener only works once and not with the expected if statement 单击标签不会触发单击事件 - Clicking on label doesn't trigger click event 点击事件未触发预期效果 - Click event doesn't trigger desired effect 就我而言，点击事件不会触发 - Click event doesn't trigger in my case 首次点击不会触发事件 - First click doesn't trigger an event Javascript点击监听器，但是不会在子元素上触发吗？ - Javascript click listener, but doesn't trigger on child element? 事件侦听器不会在 JavaScript 上触发动态创建的元素 - Event listener doesn't trigger dynamically created element on JavaScript
