HomeWeb Front-endJS TutorialjQuery uses EasyUi to realize three-level linkage drop-down box effect example sharing

This article mainly introduces jQuery's use of EasyUi to achieve three-level linkage effects. Examples of using EasyUi to achieve three-level linkage techniques are very practical. Friends in need can refer to it. I hope it can help everyone.

Not to mention anything else, using easyui to achieve three-level linkage is mainly to layer one layer inside another. Let’s take a look at the code

html form


<input id="txtPipeRowName" style="width:150px;">    
<input id="txtPipeName" style="width:150px;">

easyUi's Combobox:


// 一层Combo 
var srmCombx = $("#txtShouName")combobox({ 
loader:function(param,success,error){ 
  $ajax({ 
url: &#39;${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id=&#39;+selectSgId+&#39;&#39;, 
dataType: &#39;json&#39;, 
success: function(data){ 
dataunshift({equipmentid:&#39;&#39;,equipmentname:&#39;全部&#39;}); 
success(data); 
}, 
        error: function(){ 
errorapply(this, arguments); 
} 
}); 
  }, 
  onSelect:function(record){ //onSelect 用户点击时触发的事件 在此的意义在于,用户点击一级后自动二级combobox 
  piperowCombxcombobox({ 
loader:function(param,success,error){ 
  $ajax({ 
url: &#39;${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id=&#39;+$("#txtShouName")combobox("getValue")+&#39;&#39;,

dataunshift({equipmentid:&#39;&#39;,equipmentname:&#39;全部&#39;}); 
success(data); 
}, 
        error: function(){ 
errorapply(this, arguments); 
} 
}); 
  }, 
  onSelect:function(record){ //这里也使用了onSelect事件,在二级combobox被用户点击时触发三级combobox 
  pipeCombxcombobox({ 
loader:function(param,success,error){ 
  $ajax({

  }, 
  onLoadSuccess:function(){ //清空三级下拉框 就是成功加载完触发的事件 当一级combobox改变时,二级和三级就需要清空 
  pipeCombxcombobox("clear"); 
  pipeCombxcombobox(&#39;setValue&#39;, &#39;全部&#39;); //给combobox下拉框设置一个值,否则为空不好看

  textField: &#39;equipmentname&#39;, 
  value:&#39;&#39;, 
  editable:false

Python vs. JavaScript: Community, Libraries, and ResourcesPython vs. JavaScript: Community, Libraries, and ResourcesApr 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.

From C/C   to JavaScript: How It All WorksFrom C/C to JavaScript: How It All WorksApr 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 Engines: Comparing ImplementationsJavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
