如果你想禁用所有使用jQuery的模态的外部点击，使用这个。在jQuery之后添加这个脚本到你的Javascript。

jQuery(document).ready(function () {
    jQuery('[data-toggle="modal"]').each(function () {
       jQuery(this).attr('data-backdrop','static');
       jQuery(this).attr('data-keyboard','false');
    });
});

如果你正在使用@ng-bootstrap，请使用以下命令:

组件

import { Component, OnInit } from '@angular/core';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.scss'],
})
export class ExampleComponent implements OnInit {

  constructor(
    private ngbModal: NgbModal
  ) {}

  ngOnInit(): void {
  }

  openModal(exampleModal: any, $event: any) {
    this.ngbModal.open(exampleModal, {
      size: 'lg', // set modal size
      backdrop: 'static', // disable modal from closing on click outside
      keyboard: false, // disable modal closing by keyboard esc
    });
  }
}

模板

<div (click)="openModal(exampleModal, $event)"> </div>
    <ng-template #exampleModal let-modal>
        <div class="modal-header">
            <h5 class="modal-title">Test modal</h5>
        </div>
        <div class="modal-body p-3">
            <form action="">
                <div class="form-row">
                    <div class="form-group col-md-6">
                        <label for="">Test field 1</label>
                        <input type="text" class="form-control">
                    </div>
                    <div class="form-group col-md-6">
                        <label for="">Test field 2</label>
                        <input type="text" class="form-control">
                    </div>

                    <div class="text-right pt-4">
                        <button type="button" class="btn btn-light" (click)="modal.dismiss('Close')">Close</button>
                        <button class="btn btn-primary ml-1">Save</button>
                    </div>
            </form>
        </div>
    </ng-template>

这段代码在angular 9上测试，使用:

“@ng-bootstrap / ng-bootstrap”:1 ^ 6。0, “引导”:“^ 4。4 . 1”,

在Options一章中，在您链接的页面中，您可以看到背景选项。通过这个值为static的选项将阻止关闭模态。 正如@PedroVagner在评论中指出的那样，你也可以通过传递{keyboard: false}来防止按Esc关闭模态。

如果你用js打开模态，使用:

$('#myModal').modal({backdrop: 'static', keyboard: false})  

如果您正在使用数据属性，请使用:

 <button data-target="#myModal" data-toggle="modal" data-backdrop="static" data-keyboard="false">
    Launch demo modal
 </button>`

将此CSS用于模态和模态对话框

.modal{
    pointer-events: none;
}

.modal-dialog{
    pointer-events: all;
 }

这可以解决您在Modal中的问题

如果你不知道模式是否已经打开或者还没有打开，你需要配置模式选项，还有一个选项:

引导3.4

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal').options.keyboard = keyboard;
    $modal.data('bs.modal').options.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

引导 4.3+

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal')._config.keyboard = keyboard;
    $modal.data('bs.modal')._config.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

将选项更改为_config

你可以像这样使用一个属性:data- background ="static"或者使用javascript:

$('#myModal').modal({
    backdrop: 'static',
    keyboard: false  // to prevent closing with Esc button (if you want this too)
})
