Dojo 表单中的验证

Question

我有一个 dojo 表单，其中有 5 个字段：其中 2 个是验证文本框，1 个是过滤选择，2 个是数字文本框。单击搜索按钮时，我希望用户至少输入 5 个字段中的一个值。我如何应用此验证？

谢谢

您需要使用dijit/form/Form http://dojotoolkit.org/reference-guide/1.10/dijit/form/Form.html#dijit-form-form

require(["dojo/parser", "dijit/form/Form", "dijit/form/Button", "dijit/form/ValidationTextBox", "dijit/form/DateTextBox"], function(parser) {
    document.body.className += ' tundra'; //just to have the proper css  in the snippet
  
  
    parser.parse() //to render properly in the snippets
    
    
    //here is the part you are looking for:
    getValues = function() {
      console.log(myForm.getValues());
      values = myForm.getValues();
      var oneHasValue = false;
      for(var i in values) {
         if(values[i]) {
           oneHasValue = true;
           break;
         }
      }
      if(!oneHasValue) {
         alert('at least one field should not be empty')  
      }
    }
    
});
