jQuery deferred.resolve()用法及代码示例

JQuery中的deferred.resolve()方法用于解析Deferred对象并使用给定参数调用任何doneCallbacks。句法：

deferred.resolve([args])

参数：

args:这是可选参数，是传递给doneCallbacks的参数。

返回值：此方法返回延迟的对象。

下面讨论了两个示例：

例：在此示例中，使用参数调用resolve()。

<!DOCTYPE HTML>  
<html>   
<head>  
    <title>  
      JQuery | deferred.resolve() method 
    </title> 
    <script src="https://code.jquery.com/jquery-3.5.0.js"> 
    </script>  
</head>    
<body style="text-align:center;"> 
    <h1 style="color:green;">   
        GeeksForGeeks   
    </h1>  
    <p id="GFG_UP">  
    </p> 
    <button onclick = "Geeks();"> 
    click here 
    </button> 
    <p id="GFG_DOWN">  
    </p> 
    <script>  
        var el_up = document.getElementById("GFG_UP"); 
        el_up.innerHTML = "JQuery | deferred.resolve() method"; 
        function Func(val, div){ 
          $(div).append(val); 
        } 
        function Geeks() { 
            var def = $.Deferred(); 
            def.done(Func); 
            def.resolve( 
'resolve() method is called with arguments  
           and Deferred object is resolved', '#GFG_DOWN') 
        }  
    </script>  
</body>    
</html>

输出：

例：在此示例中，不带参数的情况下调用了resolve()。

<!DOCTYPE HTML>  
<html>   
<head>  
    <title>  
      JQuery | deferred.resolve() method 
    </title> 
    <script src="https://code.jquery.com/jquery-3.5.0.js"> 
    </script>  
</head>    
<body style="text-align:center;"> 
    <h1 style="color:green;">   
        GeeksForGeeks   
    </h1>  
    <p id="GFG_UP">  
    </p> 
    <button onclick = "Geeks();"> 
    click here 
    </button> 
    <p id="GFG_DOWN">  
    </p> 
    <script>  
        var el_up = document.getElementById("GFG_UP"); 
        el_up.innerHTML = "JQuery | deferred.resolve() method"; 
        function Func(){ 
          $('#GFG_DOWN').append( 
"resolve() method is called without arguments 
          and Deferred object is resolved"); 
        } 
        function Geeks() { 
            var def = $.Deferred(); 
            def.done(Func); 
            def.resolve() 
        }  
    </script>  
</body>    
</html>
