Bootstrap 日期选择器禁用功能 [英] Bootstrap datepicker disable feature

问题描述

我的项目需要一个我认为 bootstrap datepicker 仍然没有提供的功能.我想启用/禁用日期选择器字段，以便用户无法更改其值.类似于只读功能.

I need in my project a feature I think bootstrap datepicker still doesn't offer. I'd like to enable/disable a datepicker field so a user can't be able to change its value. Something like a readOnly functionality.

对此有什么想法吗?

提前致谢.

推荐答案

我找到了一个解决方案，但只是通过修改引导日历代码.覆盖 this._events 部分以禁用 keyup/down 事件对我有用:

I found a solution, but just by modifying the bootstrap calendar code. Overriding the this._events part to disable keyup/down event worked for me:

_buildEvents: function(){
        if (this.isInput) { // single input
            this._events = [
                [this.element, {
                    focus: $.proxy(this.show, this),
                    keyup: $.proxy(this.update, this),
                    keydown: $.proxy(this.keydown, this)
                }]
            ];
        }
        else if (this.component && this.hasInput){ // component: input + button
            this._events = [
                // For components that are not readonly, allow keyboard nav
                [this.element.find('input'), {
                    //focus: $.proxy(this.show, this),
                    //keyup: $.proxy(this.update, this),
                    //keydown: $.proxy(this.keydown, this)
                }],
                [this.component, {
                    click: $.proxy(this.show, this)
                }]
            ];
        }
        else if (this.element.is('div')) {  // inline datepicker
            this.isInline = true;
        }
        else {
            this._events = [
                [this.element, {
                    click: $.proxy(this.show, this)
                }]
            ];
        }

        this._secondaryEvents = [
            [this.picker, {
                click: $.proxy(this.click, this)
            }],
            [$(window), {
                resize: $.proxy(this.place, this)
            }],
            [$(document), {
                mousedown: $.proxy(function (e) {
                    // Clicked outside the datepicker, hide it
                    if (!(
                        this.element.is(e.target) ||
                        this.element.find(e.target).length ||
                        this.picker.is(e.target) ||
                        this.picker.find(e.target).length
                    )) {
                        this.hide();
                    }
                }, this)
            }]
        ];
    },
