如何动态地在“ ValidationTextBox”之前添加“ HTML标签”？

Question

我需要在每个ValidationTextBox之前动态添加HTML labels 。

ValidationTextBox和HTML标签是根据对象data存在的属性数量而创建的。

我需要一个如何做的例子。

示例： http ： //jsfiddle.net/F2qAN/97/#run

dojo.require("dijit.form.ValidationTextBox");
dojo.require("dijit.layout.ContentPane");

    function build() {
        var data = {
            name: 'a',
            surname: 'b',
            age: 'c'
        },
        validationTextBox,
        layout = new dijit.layout.ContentPane({});
        Object.keys(data).forEach(function (prop, index) {
            validationTextBox = new dijit.form.ValidationTextBox({
                id: prop + '-'+ index,
                name: prop,
                value: data[prop]
            });
            layout.addChild(validationTextBox);
        }.bind(this))
        layout.placeAt('layout');
        layout.startup();
    }

    dojo.addOnLoad(build);

我正在尝试使用dojo/dom-construct但没有结果，例如：

        var label = domConstruct.toDom("<label for="male">label</label>");
        layout.addChild(validationTextBox);
        layout.addChild(label );

使用自制的小部件是正确的方法。

 require(['dijit/form/ValidationTextBox', 'dijit/layout/ContentPane', 'dijit/_WidgetBase', 'dijit/_TemplatedMixin', 'dojo/_base/declare', 'dojo/domReady!'], function(ValidationTextBox, ContentPane, _WidgetBase, _TemplatedMixin, declare, domReady) { var data = { name: 'a', surname: 'b', age: 'c' }, layout = new ContentPane(), LabelTextbox = declare([_WidgetBase, _TemplatedMixin], { label: '', textboxId: '', name: '', value: '', templateString: '<div><label>${label}</label><div data-dojo-attach-point="textboxNode"></div></div>', postCreate: function() { this.inherited(arguments); this.own(new ValidationTextBox({ id: this.textboxId, name: this.name, value: this.value }, this.textboxNode)); } }); Object.keys(data).forEach(function (prop, index) { layout.addChild(new LabelTextbox({ textboxId: prop + '-'+ index, name: prop, value: data[prop], label: 'foo' })); }.bind(this)); layout.placeAt('layout'); layout.startup(); }); 

 <link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/dojo/1.10.4/dijit/themes/claro/claro.css" media="screen"> <script src="//ajax.googleapis.com/ajax/libs/dojo/1.10.4/dojo/dojo.js"></script> <div id="layout"></div>

我找到了使用dojo.place（）的解决方案。

仍然有兴趣了解是否有其他方法可以达到相同的结果。

http://jsfiddle.net/F2qAN/101/

dojo.require("dijit.form.ValidationTextBox");
dojo.require("dijit.layout.ContentPane");
dojo.require("dojo");

function build() {
    var data = {
        name: 'a',
        surname: 'b',
        age: 'c'
    },
    validationTextBox,
    layout = new dijit.layout.ContentPane({});
    Object.keys(data).forEach(function (prop, index) {
        validationTextBox = new dijit.form.ValidationTextBox({
            id: prop + '-'+ index,
            name: prop,
            value: data[prop]
        });
        dojo.place("<label>MY LABEL</label>", layout.containerNode);
        layout.addChild(validationTextBox);
    }.bind(this))
    layout.placeAt('layout');
    layout.startup();
}

dojo.addOnLoad(build);
