执行函数时关闭Bootstrap Modal(使用Javascript而非Jquery)

Question

我想在执行一个函数时关闭引导模式，我做到了，但当再次打开模式时，我必须双击才能打开它，我想再次单击打开它，而不是双击，谢谢

我关闭引导模式(js(的代码

// To Close Modal
document.getElementById('ItemModel').classList.remove('show');
document.getElementById('ItemModel').style.display = 'none';
document.getElementsByClassName('modal-backdrop')[0].remove();
document.body.classList.remove('modal-open');
document.body.style.padding = '0';

Answer 1

我相信我们都知道这很可能是一种变通方法。有时这会让工作更容易完成。因此，有一个显示/隐藏Bootstrap 4模式的变通方法。

没有jQuery(但在TypeScript中(，您可以使用以下逻辑：

showModal(){
let modal = document.getElementById('downloadModal') as HTMLElement;
let modalDismiss = modal.querySelector('[data-dismiss]') as HTMLButtonElement;
let backdrop = document.createElement('div') as HTMLElement;
modal.setAttribute('aria-modal', 'true');
modal.style.paddingRight = '16px';
modal.style.display = 'block';
modal.removeAttribute('aria-hidden');
document.body.style.paddingRight = '16px';
document.body.classList.add('modal-open');
backdrop.classList.add('modal-backdrop', 'fade');
document.body.appendChild(backdrop);
backdrop.addEventListener('click', this.hideModal.bind(this));
modalDismiss.addEventListener('click', this.hideModal.bind(this));
setTimeout(function(){
modal.classList.add('show');
backdrop.classList.add('show');
}, 200);
}
hideModal(){
let modal = document.getElementById('downloadModal') as HTMLElement;
let modalDismiss = modal.querySelector('[data-dismiss]') as HTMLButtonElement;
let backdrop = document.querySelector('.modal-backdrop');
modal.classList.remove('show');
backdrop.removeEventListener('click', this.hideModal.bind(this));
modalDismiss.removeEventListener('click', this.hideModal.bind(this));
setTimeout(function(){
modal.style.display = 'none';
modal.removeAttribute('aria-modal');
modal.removeAttribute('style');
modal.setAttribute('aria-hidden', 'true');
document.body.removeAttribute('style');
document.body.classList.remove('modal-open');
backdrop.remove();
}, 200);
}

我希望这不会阻止您将其转换为普通的JavaSript逻辑。
