Question

我在此示例中看到jsViews验证组，它存在于模板中并包含要验证的所有字段。 http://www.jsviews.com/#samples/tag-controls/datepicker/with-validation-wizard

是否也可以使用顶级数据链接表单元素形成验证组，就像在这个jsfiddle中一样？ http://jsfiddle.net/xnerzqt6/

var app = {
    formData: {
        selectedThing: "",
        selectedPlace: "",
        selectedAction: ""
    }
};


$("#content").link(true, app);

.val-msg {
	margin-right: 5px;
}

.invalid.val-msg {
	border: 2px solid #cf321d;
}

.radiogroup.val-msg {
	padding: 3px;
	display: inline-block;
}

.radiogroup.invalid.val-msg {
	margin: 5px;
}

select.invalid.val-msg {
	margin: 4px;
}

select.val-msg {
	margin: 5px;
}

input[type=radio] {
	margin: 3px 3px 3px 5px;
	padding: 0;
}

label.error {
	color: #cf321d;
	font-style: italic;
}

    <span>large block of unrelated stuff</span><br/>
    <input data-link='{validate formData.selectedAction trigger=true minLength=8}'/><br/>
    <input type='button' value='Submit'/><br/>
    <span>should not be able to submit while any validation fails</span>
</div>

您链接到的validation wizard示例使用“验证”验证组标记和“验证”标记，这些标记是为模板中的嵌套标记编写的：

{^{validation}}
    {^{validate .../}}
    {^{validate .../}}
{{/validation}}

所以你有两个选择。 1）编写一个新的验证组标签，用于处理顶级数据链接，或者2）在页面中包含一些“填充代码”，以编程方式将验证标签实例连接到验证组标签。

＃2实际上非常可行 - 这里是jsfiddle：http://jsfiddle.net/BorisMoore/xf0Lnufw/

额外的垫片代码如下：

// Get the validationGroup 'validation' tag
var validationGroup = $.view().childTags("validation")[0];

$.view().childTags("validate").forEach(function(validateTag) {
    // For each 'validate' tag, associate with validationGroup.
    validateTag.validationGroup = validationGroup;
    validationGroup.addChild(validateTag);
});

validationGroup.validate(); // Run the validation group validate() method

// Data-link the disabled state of the submit button to be disabled except
// when the validationGroup is valid.
$.link(
    "disabled{:!~validation.isValid}",
    "#submitBtn",
    app,
    {validation: validationGroup}
);

JsViews顶级数据链接验证组语法？
