仅触发一次点击事件 [英] Trigger click event only once

问题描述

我只想在浏览器的屏幕宽度为800px时触发click事件，但是根据以下逻辑，当我到达800并停止调整屏幕大小时，click事件会不停地来回触发.我该如何解决这个问题.

I want to trigger the click event only when the screen width of the browser is 800px, however with the logic below, the click event is triggered back and forth nonstop when i reach at the 800 and stop resizing the screen. How can i fix this issue.

html文件:

<!-- begin sidebar minify button -->
<a href="javascript:;" class="sidebar-minify-btn" data-click="sidebar-minify">
   <i class="fa fa-angle-left"></i>
</a>
<!-- end sidebar minify button -->

js文件:

window.onresize = function()
{
     const width = window.innerWidth;
     if(width === 800)
     {

        $('a[data-click="sidebar-minify"]').trigger('click');
        console.log('click event triggered');
     }
}

推荐答案

一种可能的方法是，当不再需要使用

One possible way could be to remove the resize listener when no longer needed using EventTarget.removeEventListener() like this:

function resizeListener() {
  if (window.innerWidth === 800) {
    window.removeEventListener('resize', resizeListener);
    $('a[data-click="sidebar-minify"]').trigger('click');
    console.log('click event triggered');
  }
}

window.addEventListener('resize', resizeListener);
