javascript - 首次单击提交按钮时如何始终隐藏 div？

问题描述

我想<div id="hideOnSubmit">在按下提交按钮后永久隐藏

我正在创建一个多步骤表单，我的意思是当用户跳过第一步时，div 消失

<div class="frm_submit">
[if back_button]<button type="submit" name="frm_prev_page" formnovalidate="formnovalidate" class="frm_prev_page" [back_hook]>[back_label]</button>[/if back_button]
<button class="frm_button_submit" type="submit" id="toggle" [button_action]>[button_label]</button>
<div class="frm_button_submitt" id="hideOnSubmit">
<label><input type="checkbox" name="rememberMe" value="true" tabindex="4"><i class="a-icon a-icon-checkbox"></i><span class="a-label a-checkbox-label">
          Keep me signed in.
          <span class="a-declarative" data-action="a-popover" data-a-popover="{&quot;activate&quot;:&quot;onclick&quot;,&quot;header&quot;:&quot;\&quot;Keep Me Signed In\&quot; Checkbox&quot;,&quot;inlineContent&quot;:&quot;\u003cp>Choosing \&quot;Keep me signed in\&quot; reduces the number of times you're asked to Sign-In on this device.\u003c\/p>\n\u003cp>To keep your account secure, use this option only on your personal devices.\u003c\/p>&quot;}">
            <a id="remember_me_learn_more_link" href="javascript:void(0)" class="a-popover-trigger a-declarative">
              Details
            <i class="a-icon a-icon-popover"></i></a>
          </span>
</span></label>
</div>
[if save_draft]<a href="#" tabindex="0" class="frm_save_draft" [draft_hook]>[draft_label]</a>[/if save_draft]
</div>

const elementToHide = document.querySelector("#hideOnSubmit");

document.querySelector("#toggle").addEventListener("click", () => {
  elementToHide.style.display = "none";
});

它在第一步中消失了，但我希望它在接下来的步骤中消失

标签： javascript

解决方案

这是一个简单的解决方案。只需使用计数器。

const element = document.getElementById("hide");
let clickCount = 0;

element.addEventListener("click", (e) => {
  if(clickCount > 0) return element.style.display = "none";
  
  console.log("Clicked")
  clickCount++;
});  
<div id="hide">Hide me on the second Click</div>
