道場按鈕沒有被禁用

Question

我遇到了dojo按鈕的問題。 我想單擊按鈕時禁用其他dojo按鈕。產生

var show = new Button({ 
    label: _('Button'), 
    onClick: function() {                              
     var buttonsChange = query('.changeButton'); 
     buttonsChange.attr('disabled',true);   
    } 
}); 

和HTML代碼是這樣的：

<span class="btn" dojoattachpoint="iconNode" dojoattachevent="ondijitclick:_onClick" widgetid="change_2"> 
    <button type="submit" dojoattachpoint="focusNode" tabindex="0" id="change_2" class="changeButton" style="-webkit-user-select: none;"> 
      <span dojoattachpoint="containerNode">Change priority</span> 
    </button> 
</span> 

預先感謝。

您需要的是小部件（例如使用dijit/registry）。而不是domnode

require(['dijit/form/Button', 'dijit/registry', 'dojo/query', 'dojo/domReady!'], function(Button, registry, query) { 
 

 
var testDiv = document.getElementById('test'); 
 

 
var btn1 = new Button({ 
 
    label: 'click to disable button 2 and button 3', 
 
    onClick: function() {                              
 
     var buttonsChange = query('.changeButton'); 
 
     buttonsChange.forEach(function(button) { 
 
     registry.byNode(button).set('disabled', true); 
 
     });   
 
    } 
 
}).placeAt(testDiv); 
 
    
 
var btn2 = new Button({ 
 
    label: 'button 2', 
 
    'class': 'changeButton' 
 
}).placeAt(testDiv); 
 
    
 
var btn3 = new Button({ 
 
    label: 'button 3', 
 
    'class': 'changeButton' 
 
}).placeAt(testDiv); 
 
    
 
});
