I'm a bit lazy, so the tutorials about jquery ui have never been updated, I'm sorry. Getting started with jquery ui will briefly explain the concept, use and general introduction of jquery ui. Starting from this article, we will start to explain the use of some specific components in jquery ui. This article explains the use of jquery ui dialog:
We often use dialog boxes when interacting. Yes, jquery ui dialog was born for this. jquery ui dialog provides us with a simpleinterface to implement normal It requires a lot of javascript code to achieve the effect. We can use jquery ui dialog to achieve many functions, such as login, registration and message prompts.
Before using the dialog component, you must first introduce the js files that the dialog depends on into the page. These files include js files and css files, and all dialog style example codes are in /development-bundle/demos In the /dialog/ directory, open the source code and see how to use a type of dialog. If you don't understand what I'm talking about, just go and see how to use it after downloading jquery UI. If you don’t have the jquery ui code package yet, then you should download it first: jquery UI download for each version Let’s take /development-bundle/demos/dialog/default.html as an example to look at the header of jquery ui dialog Introduction of external files<!--载入主题样式--> <script type="text/javascript" src="../../jquery-1.6.2.js"></script> <!--载入 jquery 核心类库--> <script type="text/javascript" src="../../external/jquery.bgiframe-2.1.2.js"></script> <!--这个主要是为了兼容 IE6 而载入的一个插件--> <script type="text/javascript" src="../../ui/jquery.ui.core.js"></script> <!--载入 jquery ui 核心类库--> <script type="text/javascript" src="../../ui/jquery.ui.widget.js"></script> <!--载入 jquery ui 组件核心类库--> <script type="text/javascript" src="../../ui/jquery.ui.mouse.js"></script> <!--载入 jquery ui 鼠标相关组件--> <script type="text/javascript" src="../../ui/jquery.ui.draggable.js"></script> <!--载入 jquery ui 拖动相关组件,主要是为了让 dialog 能够被拖动--> <script type="text/javascript" src="../../ui/jquery.ui.position.js"></script> <!--载入 jquery ui 位置相关组件,主要是为了让 dialog 能够居中或者控制位置--> <script type="text/javascript" src="../../ui/jquery.ui.resizable.js"></script> <!--载入 jquery ui 调整大小相关组件,主要是为了让 dialog 的大小能够通过鼠标来调整--> <script type="text/javascript" src="../../ui/jquery.ui.dialog.js"></script> <!--载入 jquery ui 对话框组件-->Some of these imported files are not necessary and need to be determined according to the parameters of the dialog. For example, if you do not need to adjust the size of the dialog, you do not need to load jquery.ui.resizable. js file, let’s take a look at how the dialog is popped up.
<script type="text/javascript"> $(function() { $( "#dialog" ).dialog(); }); </script>Yes, the use of dialog is that simple. Of course, dialog also has many parameters to help you realize many complex functions. We will do that later. I will also explain to you that the use of these parameters is basically very simple.
The above is the detailed content of Tutorial on using dialog using jQuery UI. For more information, please follow other related articles on the PHP Chinese website!

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。
