本文介绍了如何动态地在“ ValidationTextBox”之前添加“ HTML标签”?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

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


$ b根据对象 data 中存在的属性数,分别创建$ b

ValidationTextBox 和HTML标签。 p>

我需要一个示例来说明如何操作。



示例:

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

函数build(){
var data = {
名称: a,
姓: b,
年龄: c
},
validationTextBox,
layout = new dijit.layout.ContentPane({});
Object.keys(data).forEach(function(prop,index){
validationTextBox = new dijit.form.ValidationTextBox({
id:prop +'-'+ index,
名称:prop,
值: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>标签< / label>); 
layout.addChild(validationTextBox);
layout.addChild(label);


解决方案

使用自制窗口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!'],函数(ValidationTextBox,ContentPane,_WidgetBase,_TemplatedMixin,declaration,domReady){var data = {名称:'a',姓氏:'b',年龄:'c'},布局=新的ContentPane(),LabelTextbox =声明([_WidgetBase,_TemplatedMixin],{label:``,textboxId:'',name:'',value:'',templateString:'< div< label> $ {label}< / label>< div data-dojo-attach-point = textboxNode>< / div>< / div>',postCreate:function(){this .inherited(参数); 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();});

I need to add dynamically HTML labels before each ValidationTextBox.

ValidationTextBox and HTML label are created accordingly to the number of property present for object data.

I would need an example on how to do it.

Example: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);

I am trying using dojo/dom-construct but with no result, ex:

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

Using a home made widget is the proper approach for that.

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>
