There is a dialog in jquery; the dialog is a UI component of the jQuery UI library. The advantage of using this component is that there is no need to refresh the web page, and a div layer can be popped up directly to allow the user to input information; when using this component, not only must it be introduced jquery, as well as js and related css files that introduce jQueryUI.

Is there a dialog in jquery?
Dialog is a UI component of the jQuery UI library, so when using dialog, you must not only introduce jQuery.js (because it is only a lightweight foundation Framework), you also need to introduce jQueryUI js and related css files
The advantage of using dialog is that there is no need to refresh the web page, and a div layer will pop up directly to allow the user to input information. It is also more convenient to use.
jquery ui-dialog is still widely used in web development. The most common example is the implementation of the login function.
The example is as follows:
The simplest implementation is to configure a dialog box in jquery's ready method. Such as:
$("#dialogDiv").dialog();
But this does not meet our requirements, so we need to understand its common properties and methods. This is the configuration in my demo. As follows:
$("#dialogDiv").dialog({ autoOpen : false, // 是否自动弹出窗口 modal : true, // 设置为模态对话框 resizable : true, width : 410, //弹出框宽度 height : 240, //弹出框高度 title : "用户登录", //弹出框标题 position : "center", //窗口显示的位置 buttons:{ '确定':function(){ //调用登录的方法 }, '取消':function(){ $(this).dialog("close"); } } });
Note: "dialogDiv" represents the id of the element.
Commonly used attributes
autoOpen: When this attribute is true, the dialog window will be automatically opened when the dialog is called. When the attribute is false, the window is initially hidden, and the dialog window pops up when dialog("open") is called. Default: true.
position: the display position of the dialog: it can be 'center', 'left', 'right', 'top', 'bottom', it can also be the offset of top and left, or it can be one character String array such as ['right','top'].
title: The title of the dialog, empty by default.
modal: Whether to use a modal window. After the modal window is opened, other elements on the page will not be clickable until the modal window is closed. Defaults to false to not modal the window.
closeOnEscape: When true, click the ESC key on the keyboard to close the dialog. The default is true.
draggable: Whether draggable can be dragged using the title header. The default is true and draggable is possible.
resizable: whether resizable can change the size of the dialog. The default is true and the size can be changed.
Commonly used methods
open: open the dialog, one sentence $("#id").dialog("open").
close: Close the dialog, one sentence $("#id").dialog("close").
disable: Set the dialog to be unavailable.
enable: Set the dialog to be available.
isOpen: Determine whether the dialog is open. If it is open, return true.
destroy: Destroy the dialog.
moveToTop: Move the dialog to the top.
option: used to set and remove the value of the dialog. For example, we set the title for the dialog, code: $("#dialogDiv").dialog("option", "title", "Login")
Take a look at my demo, which simply calls the open method. You can try other methods yourself. For more attributes and methods, please go to the official website to see the API, address: http://api.jqueryui.com/dialog/. This is my login page. Calling method:
$("#dialogDiv").dialog("open");
The effect is as shown:

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

在jquery中,apply()方法用于改变this指向,使用另一个对象替换当前对象,是应用某一对象的一个方法,语法为“apply(thisobj,[argarray])”;参数argarray表示的是以数组的形式进行传递。

去掉方法:1、用“$(selector).removeAttr("readonly")”语句删除readonly属性;2、用“$(selector).attr("readonly",false)”将readonly属性的值设置为false。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。
