JQuery+EasyUI easily realizes the step bar effect_jquery

EasyUI Introduction

easyui is a collection of user interface plug-ins based on jQuery.

easyui provides the necessary functionality for creating modern, interactive, JavaScript applications.

Using easyui, you don’t need to write a lot of code. You only need to define the user interface by writing some simple HTML tags.

easyui is a complete framework that perfectly supports HTML5 web pages.

easyui saves the time and scale of your web development.

easyui is very simple but powerful.

jQuery EasyUI provides easy-to-use components that enable web developers to quickly build application pages based on the popular jQuery core and HTML5.

Let me show you the renderings first:

Project requirements: When we usually shop, it is often a step like placing an order, making payment, the seller shipping, confirming receipt, and evaluating. So if the UI is designed with a progress bar, the user can clearly see where they are and what steps they need to take.

Let’s take a look at the front-end framework of our project, which uses EasyUI+MVC. I only need to write a few JS to interact with the view. It took me a day to see how the entire page is implemented. , basically refer to an easyUI style, use AJAX to pass the value, and call the method in the background controller. Since I am implementing the dynamic effect of a front-end page, I write the JQuery method on the previous step and the next step to perform switch selection to activate and complete the node. Write a JS method to choose to control the display and hiding of the main page. I wrote the view into several divs, so my method is to jump to the display of several divs.

Review the knowledge points of JQuery:

1. The form loading event corresponds to the window.onload method

2. There are many kinds of button binding events

1) Use JS to write a function and place it on the onclick event of the button.

2) Use JQuery to bind an anonymous function $('#btnnext').bind('click', function (){});

3. Add and delete classes removeclass and addclass, the difference between ID and class, in JQuery ID starts with #

4. The difference between js and JQuery is that the latter expresses the most meaning with the least code, and the latter is a higher-level encapsulation of the former.

5. The difference between the types of AJAX background transfer methods POST and GET. GET transfers a smaller amount of data than it does. The user's transmission is transferred through URL requests, while POST requires submitting a form and is highly secure.

I only show the progress bar in the view part:

@*步骤条*@ 
<div class="row" style="margin-top:3%"> 
<div class="col-md-2" ></div> 
@* 步骤条所在区域*@ 
<div class="col-md-8"> 
@*步骤条*@ 
<ol class="ui-step ui-step-4"> 
<li id="li1" class="ui-step-start ui-step-active" > 
<div class="ui-step-line">-</div> 
<div id="d1" class="ui-step-icon"> 
<i class="iconfont">&#61487;</i> 
<i class="ui-step-number">1</i> 
<span class="ui-step-text">填写项目信息</span> 
</div> 
</li> 
<li id="li2" class="ui-step-line"> 
<div class="ui-step-line">-</div> 
<div class="ui-step-icon"> 
<i class="iconfont">&#61487;</i> 
<i class="ui-step-number">2</i> 
<span class="ui-step-text">生成招标编号</span> 
</div> 
</li> 
<li id="li3" class="ui-step-line"> 
<div class="ui-step-line">-</div> 
<div class="ui-step-icon"> 
<i class="iconfont">&#61487;</i> 
<i class="ui-step-number">3</i> 
<span class="ui-step-text">设置评标方法</span> 
</div> 
</li> 
<li id="li4" class="ui-step-end"> 
<div class="ui-step-line">-</div> 
<div class="ui-step-icon"> 
<i class="iconfont">&#61487;</i> 
<i class="ui-step-number">4</i> 
<span class="ui-step-text">生成招标文件</span> 
</div> 
</li> 
</ol> 
</div> 
<div class="col-md-2"></div> 
</div> 

Add the css style that needs to be referenced by the progress bar:

@*进度条需要引用的文件*@ 
@* AliceUI基础样式 *@ 
<link href="../../Content/base-master/src/base.css" rel="stylesheet" /> 
@* 步骤条样式 *@ 
<link href="../../Content/step-master/step.css" rel="stylesheet" /> 
@*AliceUI图标字体*@ 
<link href="../../Content/iconfont-master/index.css" rel="stylesheet" />

The above is a small introduction to JQuery+EasyUI to easily achieve the step bar effect. I hope it will be helpful to everyone!
