yii2.0 static resource js css introduction method

Configure resource bundle:

Yii2 uses the AssetBundle resource package class for CSS/JS management.

Open backend/assets/AppAsset.php

namespace backendassets; 
use yiiwebAssetBundle; 
class AppAsset extends AssetBundle { 
public $basePath = [email protected]/* */'; 
public $baseUrl = [email protected]/* */';

//全局CSS 
public $css = [ 
'css/animate.css', 
'css/style.min.css', 
]; 

//全局JS 
public $js = [ 
'js/jquery-2.1.1.js' 
]; 

//依赖关系 
public $depends = [ 
'yiiwebYiiAsset', 
'yiiootstrapBootstrapAsset', 
]; 

//定义按需加载JS方法，注意加载顺序在最后 
public static function addScript($view, $jsfile) { 
$view->registerJsFile($jsfile, [AppAsset::className(), 'depends' => 'backendassetsAppAsset']); 
} 

//定义按需加载css方法，注意加载顺序在最后 
public static function addCss($view, $cssfile) { 
$view->registerCssFile($cssfile, [AppAsset::className(), 'depends' => 'backendassetsAppAsset']); 
} 
 }

Static resources are loaded in the view

1. The view (or layout) uses global CSS/ JS

use yiihelpersHtml; 
use backendassetsAppAsset; 
use backendwidgetsAlert; 

AppAsset::register($this);

2. Load separate styles in the view

$cssString = ".gray-bg{color:red;}"; 
$this->registerCss($cssString);

3. Load separate JS

<?php$this->registerJs( 
&#39;$("document").ready(function(){ 
$("#login-form").validate({
errorElement : "small", 
errorClass : "error",
rules: {
"AgNav[nav_cn]": {
required: true,
},
},
messages:{
"AgNav[nav_cn]" : { 
required : "此字段不能为空.",
},
}
});
});&#39;
);?>

or

<div id="mybutton">点我弹出OK</div> 

<?php $this->beginBlock(&#39;test&#39;) ?> 
$(function($) { 
$(&#39;#mybutton&#39;).click(function() { 
alert(&#39;OK&#39;); 
}); 
}); 
<?php $this->endBlock() ?> <?php $this->registerJs($this->blocks[&#39;test&#39;], yiiwebView::POS_END); ?>

4. Introduce JS/CSS files into the view

Use custom functions

public static function addScript($view, $jsfile) { 
$view->registerJsFile($jsfile, [AppAsset::className(), 'depends' => 'backendassetsAppAsset']); 
}
AppAsset::register($this); 
//只在该视图中使用非全局的jui 
AppAsset::addScript($this,[email protected]/* *//js/jquery-ui.custom.min.js'); 
AppAsset::addCss($this,[email protected]/* *//css/font-awesome/css/font-awesome.min.css');

Load directly

AppAsset::register($this); 
//css定义一样 
$this->registerCssFile([email protected]/* *//css/font-awesome.min.css',['depends'=>['backendassetsAppAsset']]); 
$this->registerJsFile([email protected]/* *//js/jquery-ui.custom.min.js',['depends'=>['backendassetsAppAsset']]);
