## 如何禁用JavaScript中的链接？ **(**How to Disable Link in JavaScript?**)** ##

### 方法1：使用CSS **(**Method 1: Using CSS**)** ###

要禁用超链接，我们使用的主要CSS属性是指针事件。 检查下面给出的代码。

**index.html**

<!DOCTYPE html>
    <html>
      <head>
        <title>
          Disable HTML href link using JS
        </title>
        <style>
          a.disabled {
            pointer-events: none;
          }
        </style>
      </head>
     
      <body style="text-align:center;">
        <h1 style="color:red;">
          Hello World
        </h1>
        <a href="https://www.thecrazyprogrammer.com/" id="linkId">
          LINK
        </a>
        <br /><br />
        <button onclick="disableLink()">
          disable  
        </button>
        <p id="linkStatus" style="color:green; font-size: 20px; font-weight: bold;"></p>
      </body>
    </html>
     
    <script>
                            let link = document.getElementById('linkId');
    			let down = document.getElementById('linkStatus');
    			function disableLink() {
    			link.setAttribute('class', 'disabled');
    			link.setAttribute('style', 'color: black;');
    			down.innerHTML = 'Link disabled';
    			}
    </script>

### 方法2：使用函数 **(**Method 2: Using Function**)** ###

<a href="https://www.thecrazyprogrammer.com/" id='TheLink'>test</a>
    <input type='button' value="Disable" onclick="disableLink( 'TheLink', this );">
     
    <script type="text/javascript">
      function disableLink(linkID, objButton) {
          const el = document.getElementById(linkID);
          if (!el.onclick) {
            el.onclick = function() {
              return false;
            };
            objButton.value = "Enable";
          } else {
            el.onclick = function() {
              return true;
            };
            objButton.value = "Disable";
          }
        }
    </script>

### 方法3：使用事件处理程序 **(**Method 3: Using Event Handler**)** ###

Event handler used to handle any action like inputting data, calling methods etc.

事件处理程序，用于处理任何操作，例如输入数据，调用方法等。

**Example:**

**例：**

<a id="openSite" href="https://www.thecrazyprogrammer.com/">open website</a>
    <button onclick=disablelink('openSite')>Disable link </button>
     
    <style>
    .disabledLink
    {
    color: #333;
    text-decoration : none;
    cursor: default;
    }
    </style>
     
    <script>
    function disablelink(linkID)
    {
    var hlink = document.getElementById(linkID);
    if(!hlink)
    return;
    hlink.href = "#";
    hlink.className = "disabledLink";
    }
    </script>

You can replace \# (hash) with javascript:void (0) event handler.

您可以将＃(哈希)替换为javascript：void(0)事件处理程序。
