In easyUI development, the solution to the problem of jquery.easyui.min.js function library_jquery
easyUI is a plug-in for jquery and a private plug-in. easyUI is very convenient to use. It contains the three most important blocks for web page production: javascript code, html code and CSS style. After importing the easyUI library, we can directly copy and paste the code inside to easily and easily initially set up the web page.
First import the easyUI function library:
<link rel="stylesheet" type="text/css" href="easyui/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="easyui/themes/icon.css"> <script type="text/javascript" src="easyui/jquery-1.7.2.min.js"></script> <script type="text/javascript" src="easyui/jquery.easyui.min.js"></script>
Project code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>欢迎来到后台管理界面</title>
<link rel="stylesheet" type="text/css" href="plugin/themes/icon.css" />
<link rel="stylesheet" type="text/css" href="plugin/themes/default/easyui.css" />
</head>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.easyui.min.js"></script>
<script type="text/javascript" src="plugin/easyloader.js"></script>
<script type="text/javascript" src="plugin/locale/easyui-lang-zh_CN.js"></script>
<script type="text/javascript">
$(function() {
$('#tt').tabs('add', {
title: '查看',
content: 'Tab Body',
closable: true,
tools: [{
iconCls: 'icon - mini - refresh',
handler: function() {
alert('refresh');
}
}]
});
});
</script>
<body class="easyui-layout">
<div data-options="region:'north',split:true" style="height:100px;">
<div>
<h1>拓胜公司后台管理系统</h1></div>
</div>
<div data-options="region:'south',split:true" style="height:60px;">
<div style="margin: auto; width: 400px ; padding: 20px; font-size: 20px;">Copyright ©拓胜公司 版权所有</div>
</div>
<div data-options="region:'west',title:'系统管理',split:true" style="width:240px;">
<div id="aa" class="easyui-accordion">
<div title="管理员管理" style="padding: 10px;">
<ul>
<li><a href="#">添加</a></li>
<li><a href="#">查看</a></li>
<li><a href="#">修改</a></li>
<li><a href="#">删除</a></li>
</ul>
</div>
</div>
</div>
<div data-options="region:'center',title:'编辑区 '" style="padding:5px;background:#eee;">
<div id="tt" class="easyui-tabs" ">
<div title="添加 " data-options="closable:true " style="overflow:auto;padding:20px;display:none; ">
tab1
</div>
<div title="删除 " data-options="closable:true " style="overflow:auto;padding:20px;display:none; ">
tab2
</div>
</div>
</div>
</body>
</html>There is no problem with the above code, but the following error occurs:
Error occurred: There is a problem with the easyUImini.js library, but the function library has been written and tested by others. According to the theory, there can be no errors.
Through various attempts, I found that after adding alert(11), the browser no longer reports errors, and the javascript code can also be executed smoothly:
<script type="text/javascript">
$(function() {
alert(11);
$('#tt').tabs('add', {
title: '查看',
content: 'Tab Body',
closable: true,
tools: [{
iconCls: 'icon - mini - refresh',
handler: function() {
alert('refresh');
}
}]
});
});
</script>After we changed the jQuery code to window.onload(), the code still runs normally:
<script type="text/javascript">
window.onload=function(){
$('#tt').tabs('add', {
title: '查看',
content: 'Tab Body',
closable: true,
tools: [{
iconCls: 'icon - mini - refresh',
handler: function() {
alert('refresh');
}
}]
});
}
</script>is summarized as:
1. The difference between window.onload() and $(function(){})
A) window.onload() waits until all elements of the page are loaded (including dom and javascript), and then executes the function code inside
B)$(function(){}) waits until the DOM element of the page is loaded, and then executes the function code inside
2. Because we are developing with easyUI, we have imported the javascript code in advance, but after using $(function(){}), the javascript has not been loaded yet, so
The jquery.easyui.min.js library will report an error. So when we use easyUI to develop projects, remember not to use $(function(){}), but it is recommended to use window.onload().
The above is the solution to the problem of jquery.easyui.min.js function library in easyUI development introduced in this article. I hope you like it.

Python vs. JavaScript: The Learning Curve and Ease of Use
Apr 16, 2025 am 12:12 AM
Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.
From C/C to JavaScript: How It All Works
Apr 14, 2025 am 12:05 AM
The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
JavaScript and the Web: Core Functionality and Use Cases
Apr 18, 2025 am 12:19 AM
The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.
JavaScript in Action: Real-World Examples and Projects
Apr 19, 2025 am 12:13 AM
JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.
Understanding the JavaScript Engine: Implementation Details
Apr 17, 2025 am 12:05 AM
Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
Python vs. JavaScript: Community, Libraries, and Resources
Apr 15, 2025 am 12:16 AM
Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
Python vs. JavaScript: Development Environments and Tools
Apr 26, 2025 am 12:09 AM
Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.
The Role of C/C in JavaScript Interpreters and Compilers
Apr 20, 2025 am 12:01 AM
C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
