带引导程序的加载按钮 5

Question

i'm trying to develop a button with a loading message. in html page i have

<div class="btn-area">
   <button id="connectMetamaskBtn" class="btn sp-btn" type="button"
           style="margin-top: 5%; width: 400px;"
           loading-text="<i class='fa fa-circle-o-notch fa-spin'></i> Connecting...">
           Connect to Metamask
              <img class="metamask-icon" src="assets/images/icons8-metamask-logo-48.png" width="25px" />
   </button>
</div>

and in app.js

$("#connectMetamaskBtn").on("click", async () => {
  var $this = $(this);
  $this.button('loading');
  try {
    provider = new ethers.providers.Web3Provider(window.ethereum);

    // MetaMask requires requesting permission to connect users accounts
    await provider.send("eth_requestAccounts", []);
    await startApp(provider);
  }
  catch (e) {
    $this.button('reset');
    $("#error")
      .text(`An error occured: ${e.message || e}`)
      .show();
  }
});

The loading doesn't work.. any idea? Thx

use this button:

 $('.btn').on('click', function() { var $this = $(this); $this.button('loading'); setTimeout(function() { $this.button('reset'); }, 8000); });
