[TimLinux] JavaScript 模态框可拖动功能实现——jQuery版的相关文章

js实现模态框的拖曳功能

项目中需要对模态框进行拖曳,以便对比模态框和页面中的元素,现demo如下: 1 <!-- saved from url=(0066)https://guguji5.github.io/bs-modal-dragable/bs-modal-dragable.html --> 2 <html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8&qu

[TimLinux] JavaScript input框的onfocus/onblur/oninput/onchange事件介绍

1. onfocus事件 input框获取到焦点时,触发了该事件,比如获取到焦点时,修改input框的背景色.这个功能其实可以使用css的伪类:focus来定义. 2. onblur事件 这个与onfocus事件想法,当input框失去焦点时,触发该事件,比如将输入的文本,统一修改为小写 3. onchange事件 这个事件的发生需要具有2个条件: 失去焦点 内容发生了变化 4. oninput事件 这个时HTML5新加入的事件,IE9之前是不支持的,在IE9之前使用的是: onproperty

实现搜索框自动提示功能（jquery+php）

客户端代码 <html> <head> <style> #search{font-size:14px;} #search .k{padding:2px 1px; width:320px;} #search_auto{border:1px solid #817FB2; position:absolute; display:none;} #search_auto li{background:#FFF; text-align:left;} #search_auto li.cl

模态框的弹出（移动版）

<!DOCTYPE html><html><head lang="zh-cn"> <meta charset="UTF-8"> <meta content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0,user-scalable=no" name="viewport"

Bootstrap 模态框强化

以下是基于bootstrap4版本做的模态框的强化功能,按需使用即可 1.ajax模态框 // ajax模态框 $('#ajaxModal').on('show.bs.modal', function (event) { var button = $(event.relatedTarget); var recipient = button.data('url'); var modal = $(this); modal.find('.modal-content').html(""); m

iframe中的模态框遮罩父窗口原理

关键点: css的position定位为fixed或absolute css的z-index, 最顶层的值最大如遮罩层为0那么弹出框最好是大于等于1的整数,总之记住弹出层要比遮罩的z-index值大就行 如果弹出模态框的使用场景没有嵌套在iframe或frame中掌握以上两点加上点css功底就可以写出漂亮的模态框了 特殊场景会涉及到跨域问题,可以在父页面和子页面分别设置<script type="text/javascript">document.domain="

使用js实现显示系统当前时间并实现倒计时功能并触发模态框（遮罩）功能

常常在我们的网页中需要倒计时来触发一些函数,例如遮罩等,在本项目中,通过使用jquery,bootstrap,实现了显示系统当前时间,并且实现了倒计时的功能,倒计时实现后将会弹出模态框(遮罩层).模态框界面友好,使用灵活,以弹出对话框的形式出现.具体见下图1: 项目源文件地址:https://github.com/zhangxy1035/Countdown 参考资料:http://v3.bootcss.com/javascript/#modals 图1: 关于倒计时函数如下: 1 var tim

Bootstrap3.0学习教程十七：JavaScript插件模态框

这篇文章中我们主要来学习一下JavaScipt插件模态框.在学习模态框之前,我们先来了解一下JavaScript插件吧. JavaScript插件概览 插件可以单个引入(使用Bootstrap提供的单个*.js文件),或一次性全部引入(使用bootstrap.js或压缩版的bootstrap.min.js). 不要将两份文件全部引入 bootstrap.js和bootstrap.min.js同样是包含了所有插件.区别是:一个没有压缩,一个进行了压缩. 插件之间的依赖 某些插件和CSS组件依赖于其

JavaScript：bootstrap 模态框的简单应用

最近用上了bootstrap这个强大的前端框架,有空来总结一下.这里记录下模态框的简单应用. 首先,要在页面中引入相应的js.css文件 1 <link href="css/bootstrap.css" rel="stylesheet" type="text/css" /> 2 <script type="text/javascript" src="js/jquery.min.js">
