ng-bootstrap模式动画

Question

fade类似乎不能在ngb-modal上工作。

我已经考虑过尝试将我自己的动画应用于模式，但模式模板显然是通过ng-bootstrap注入到模式对话中的，例如，我无法访问模式对话。我只有权访问模板：

<template #content let-c="close" let-d="dismiss">
  <div class="modal-header card-header" style="border-radius: 10px;">
    <h4 class="modal-title">Contact Form</h4>
 </div>
    <div class="modal-body"> </div>
...etc
</template>

我需要将我的动画应用到顶层对话，否则只需要少量的模态动画。如果我把它应用到模板上，它就会爆炸。

你知道我怎么让整个模型动起来吗？？

Answer 1

这是一个简单的解决方案。只需将其放入style.css即可

/* modal animation */
.modal-content{
  animation-name: example;
  animation-duration: 0.3s;
}

@keyframes example {
  0%   {transform: scale(0.5)}
  75%  {transform: scale(1.1)}
  100% {transform: scale(1)}
}

Answer 2

您需要添加动画css类到全局样式，并添加NgbModalOptions。

styles.css: //或者您的全局css是什么

.modal-holder{
  animation-name: example;
  animation-duration: 0.3s;
}

@keyframes example {
  0%   {transform: scale(0.5)}
  100% {transform: scale(1)}
}

modal.component.ts

const modalRef = this.modalService.open(NgbdModalContent, {windowClass: 'modal-holder', centered: true});

说得够多了，你可以看看下面的例子：

这里是FADE IN - OUT动画的精确副本，其中包含SLIDE as bootstrap 4.x

解决方案1:在构造函数中初始化动画

App.Component.ts：

import { NgbModal, NgbModalRef } from "@ng-bootstrap/ng-bootstrap";
  constructor(private modalService: NgbModal) {
    NgbModalRef.prototype["c"] = NgbModalRef.prototype.close;
    NgbModalRef.prototype.close = function(reason: string) {
      document.querySelector(".modal-backdrop").classList.remove("show");
      document.querySelector(".modal").classList.remove("show");
      setTimeout(() => {
        this["c"](reason);
      }, 500);
    };
    NgbModalRef.prototype["d"] = NgbModalRef.prototype.dismiss;
    NgbModalRef.prototype.dismiss = function(reason: string) {
      document.querySelector(".modal-backdrop").classList.remove("show");
      document.querySelector(".modal").classList.remove("show");
      setTimeout(() => {
        this["d"](reason);
      }, 500);
    };
  }
  open(basic) {
    this.modalService.open(basic);
  }

app.component.html :-

<div class="card">
    <div class="card-header">
        <h4 class="card-title">Basic Modal</h4>
    </div>
    <div class="card-content">
        <div class="card-body">
            <div class="row">
                <div class="col-sm-12">
                    <p>Toggle a modal via TypeScript by clicking the button above.</p>
                    <!-- Button trigger modal -->
                    <button type="button" (click)="open(basic)" class="btn btn-outline-primary block btn-lg">
                  Launch Modal
                </button>

                    <!-- Modal -->
                    <ng-template #basic let-modal>
                        <div class="modal-header">
                            <h4 class="modal-title" id="myModalLabel1">Basic Modal</h4>
                            <button type="button" class="close" (click)="modal.dismiss('Cross click')" aria-label="Close">

                        </div>
                        <div class="modal-body" tabindex="0" ngbAutofocus>
                            <h5>Check First Paragraph</h5>

                        </div>
                        <div class="modal-footer">
                            <button type="button" class="btn btn-primary" (click)="modal.close('Accept click')">Accept</button>
                        </div>
                    </ng-template>
                    <!-- / Modal -->

                </div>
            </div>
        </div>
    </div>
</div>

styles.scss :-

// modal animation
@keyframes modal-fade {
  from {
    top: -50px;
    opacity: 0;
  }

  to {
    top: 0;
    opacity: 1;
  }
}

.modal {
  top: -100px;
  animation: ease-in-out .3s modal-fade;

  &.show {
    top: 0;
  }
    .modal-body {
    &:focus {
      outline: none;
    }
  }
}

解决方案2: 在单个模式调用中初始化动画

app.component.ts :-

import { NgbModal } from "@ng-bootstrap/ng-bootstrap";
  constructor(private ngbModal: NgbModal) {}

  open(content: any, config?: any) {
    let modal = this.ngbModal.open(content, config);
    let instance = (modal as any)._windowCmptRef.instance;
    setImmediate(() => {
      instance.windowClass = "custom-show";
    });

    let fx = (modal as any)._removeModalElements.bind(modal);
    (modal as any)._removeModalElements = () => {
      instance.windowClass = "";
      setTimeout(fx, 250);
    };

    return modal;
  }

app.component.html :-

                    <!-- Button trigger modal -->
                    <button type="button" (click)="open(basic)" class="btn btn-outline-primary block btn-lg">
                  Launch Modal
