使用纯JavaScript隐藏Bootstrap模式点击

我正在开发Bootstrap Pop Up Modals。
我有两个按钮,名为Button1Button2
&
我有两个模态,名为Modal1Modal2
注意:Button2Modal1内,Button1在网页上。
如果我点击Button1Modal1应该是Open &如果我点击Modal里面的Button2,那么Modal1应该自动隐藏,Modal2应该显示。
我正在使用jQuery Yet &它工作正常。

<script>
$('#button1').click(function()
{
    $('#modal1').modal('hide');
    $('#modal2').modal('show');
});
</script>

问题:

如何使用纯JavaScript?????

这里是我写的解决方法,为了在本地JavaScript中关闭模态,使用DOM操作。使用Bootstrap 4。

function closeAllModals() {

    // get modals
    const modals = document.getElementsByClassName('modal');

    // on every modal change state like in hidden modal
    for(let i=0; i<modals.length; i++) {
      modals[i].classList.remove('show');
      modals[i].setAttribute('aria-hidden', 'true');
      modals[i].setAttribute('style', 'display: none');
    }

     // get modal backdrops
     const modalsBackdrops = document.getElementsByClassName('modal-backdrop');

     // remove every modal backdrop
     for(let i=0; i<modalsBackdrops.length; i++) {
       document.body.removeChild(modalsBackdrops[i]);
     }
  }

所以这个函数会关闭页面上所有的modals。你可以修改它,根据id关闭某个特定的modals。这样:

function closeOneModal(modalId) {

    // get modal
    const modal = document.getElementById(modalId);

    // change state like in hidden modal
    modal.classList.remove('show');
    modal.setAttribute('aria-hidden', 'true');
    modal.setAttribute('style', 'display: none');

     // get modal backdrop
     const modalBackdrops = document.getElementsByClassName('modal-backdrop');

     // remove opened modal backdrop
      document.body.removeChild(modalBackdrops[0]);
  }

所以,完全没有jQuery的线索

你可以给一个按钮分配一个id,这个按钮通常会关闭/打开一个模态,然后模拟点击这个按钮来以编程方式关闭/打开一个模态。
例如-$('#modal1').modal('hide'); $('#modal2').modal('show');将变为document.getElementById('modalX').click();

遵循纯javascript代码对我的bootstrap5很好。

let myModalEl = document.getElementById('modal1')
let modal = bootstrap.Modal.getInstance(myModalEl)
modal.hide()

工作方案如下:

您可以在应用中不编写任何Javascript的情况下实现它**YET,**我无法找到使用纯javascript的方法。锚标记上的data-target属性处理切换,请检查以下代码:

<a href="#" class="btn btn-lg btn-danger" data-toggle="modal" data-
target="#modal1">Open Modal 1</a>

我从Bootstrap的Javascript库中找到了以下内容,也许这对你有帮助!

if("undefined"==typeof jQuery)throw new Error("Bootstrap's JavaScript 
requires jQuery");

你可以使用javascript创建一个“modal”元素。好处是你可以重用它。我已经使用javascript创建了一个示例引导模式。你可以修改它以添加更多功能。

var Interface = {};
Interface.component = function ( dom ) {
    this.dom = dom;
};
Interface.component.prototype = {
    setId: function ( id ) {
        this.dom.id = id;
        return this;
    }
    // you can add more common functions here
};

Interface.BootstrapModal = function ( id, modalHeading, modalBodyContents, successButtonText, failureButtonText ) {

    var scope = this;
    var dom = document.createElement( 'div' );
    dom.className = 'modal fade';
    dom.id = id;
    dom.role = "dialog";

    var modalDialog = document.createElement( 'div' );
    modalDialog.className = 'modal-dialog';

    var modalContent = document.createElement( 'div' );
    modalContent.className = 'modal-content';

    var modalHeader = document.createElement( 'div' );
    modalHeader.className = 'modal-header';

    var modalHeaderXButton = document.createElement( 'button' );
    modalHeaderXButton.className = 'close';
    modalHeaderXButton.setAttribute("data-dismiss", "modal");
    modalHeaderXButton.innerHTML = '&times';

    var modalHeaderHeading = document.createElement( 'h3' );
    modalHeaderHeading.className = 'modal-title';
    modalHeaderHeading.innerHTML = modalHeading;

    modalHeader.appendChild(modalHeaderXButton);
    modalHeader.appendChild(modalHeaderHeading);

    var modalBody = document.createElement( 'div' );
    modalBody.className = 'modal-body';
    modalBody.appendChild(modalBodyContents);

    var modalFooter = document.createElement( 'div' );
    modalFooter.className = 'modal-footer';

    var modalFooterSuccessButton = document.createElement( 'button' );
    modalFooterSuccessButton.className = 'btn btn-success';
    modalFooterSuccessButton.id = "<GIVE THE ID YOU NEED>";
    //modalFooterSuccessButton.setAttribute("data-dismiss", "modal");
    modalFooterSuccessButton.innerHTML = successButtonText;

    var modalFooterFailureButton = document.createElement( 'button' );
    modalFooterFailureButton.className = 'btn btn-danger';
    modalFooterFailureButton.id = "<GIVE THE ID YOU NEED>";
    modalFooterFailureButton.setAttribute("data-dismiss", "modal");
    modalFooterFailureButton.innerHTML = failureButtonText;

    modalFooter.appendChild(modalFooterSuccessButton);
    modalFooter.appendChild(modalFooterFailureButton);

    modalContent.appendChild(modalHeader);
    modalContent.appendChild(modalBody);
    modalContent.appendChild(modalFooter);
    modalDialog.appendChild(modalContent);

    dom.appendChild(modalDialog);

    modalFooterSuccessButton.addEventListener( 'click', function ( event ) {

        // perform your actions

    } );

    this.dom = dom;
    return this;

};

Interface.BootstrapModal.prototype = Object.create( Interface.component.prototype );
Interface.BootstrapModal.prototype.constructor = Interface.BootstrapModal;

Interface.BootstrapModal.prototype.show = function () {

    $('#' + this.dom.id).modal({backdrop: 'static', keyboard : false});

};

Interface.BootstrapModal.prototype.hide = function () {

    $('#' + this.dom.id).modal('hide');

};

这里我已经创建了一个对象形式的模态元素。你可以像这样使用它,

var modalContent = document.createElement( 'div' );
var m = new Interface.BootstrapModal( 'id', 'modalHeading', modalContent, 'successButtonText', 'cancelButtonText' );
document.getElementById( <SOME ELEMENT> ).appendChild( m.dom );

现在**m.show()**将显示模态,**m.hide()**将隐藏模态
这可以用作引导模态的通用模板。

下面是如何在纯JS中获取modal.hide()(以及所有其他模态方法!)。
你可以在官方文档页面上尝试一下,这里以模态文档为例。问题是,模态文档在模态DOM对象上存储了一个类似于'jQuery 331042511280243656492'的属性。这个属性里面有所有的模态方法!只要先打开这个模态,然后在控制台运行代码。
UPDATE:该jQuery对象仅在第一次打开模态时被附加,并且从那时起就存在。这意味着,我们不能通过此方法'.show()'我们的模态,除非我们已经至少打开过一次。

// get reference to the modal. It's 'div.modal', in general
    var modal = document.querySelector('#exampleModalLong');
    // get the key under which the modal's methods are stored.
    var jQueryObj = Object.keys(modal).filter((key) => (key.toString().indexOf('jQuery') !== -1) && modal[key].hasOwnProperty('bs.modal'));
    // ... and close the modal!
    modal[jQueryObj]['bs.modal'].hide();

//Get modal
const bs_modal = document.getElementById(modalId);

//Change state like in hidden modal
bs_modal.classList.remove('show');
bs_modal.setAttribute('aria-hidden', 'true');
bs_modal.setAttribute('style', 'display: none');

//Get modal backdrop
const modalBackdrops = document.getElementsByClassName('modal-backdrop');

//Remove opened modal backdrop
document.body.removeChild(modalBackdrops[0]);

你能试试这个吗。。。

function showmodel(){
var Modal1 = document.getElementById("Modal1"); 
Modal1.show(); 
}
function hidemodel1()
{
var Modal1 = document.getElementById("Modal1"); 
var Modal2 = document.getElementById("Modal2"); 
Modal1.hide(); 
Modal2.show(); 
}

在button onclick中调用上面的方法。
