1、通用方法
dijit/form/TextBox :一个基本的文本框
dijit/form/SimpleTextarea :大量文字输入,一个基本的textarea
dijit/form/Textarea :一个扩展dijit/form/SimpleTextarea动态增加或减少其高度
dijit/form/NumberTextBox或dijit/form/NumberSpinner:输入是数字,确保输入一个文本框,dijit/form/NumberSpinner提供扩展dijit/form/NumberTextBox逐步改变值的按钮
dijit/form/DateTextBox :输入是日期,一个文本框,其中包括一个弹出日历
dijit/form/TimeTextBox :输入是时间,一个文本框,其中包括一个弹出时间选择器
dijit/form/CurrencyTextBox :输入是货币,一个扩展dijit/form/NumberTextBox本地化货币
dijit/form/ValidationTextBox:一个基本的验证能力,可以进一步定制
如果你要使用dijit/form/DateTextBox或dijit/form/TimeTextBox ,你将需要有主题的CSS引入并设置body元素的css样式。

<!DOCTYPEhtml> <html> <head> <linkrel="stylesheet"href="dijit/themes/claro/claro.css"> <script>dojoConfig={parSEOnLoad:true}</script> <scriptsrc='dojo/dojo.js'></script> <script> require(["dojo/parser","dijit/form/TextBox","dojo/domReady!"]); </script> <title>TextBox</title> </head> <bodyclass="claro"> <labelfor="firstname">Auto-trimming,Proper-casingTextBox:</label> <inputtype="text"name="firstname"value="testingtesting" data-dojo-type="dijit/form/TextBox" data-dojo-props="trim:true,propercase:true"id="firstname"/> </body> </html>
结果:
--编程方式
<!DOCTYPEhtml> <html> <head> <linkrel="stylesheet"href="dijit/themes/claro/claro.css"> <script>dojoConfig={parSEOnLoad:true}</script> <scriptsrc='dojo/dojo.js'></script> <script> require(["dijit/form/TextBox","dojo/domReady!"],function(TextBox){ varmyTextBox=newdijit.form.TextBox({ name:"firstname",value:""/*nooremptyvalue!*/,placeHolder:"typeinyourname" },"firstname"); }); </script> <title>TextBox</title> </head> <bodyclass="claro"> <inputid="firstname"/> </body> </html>
结果:
注意:placeHolder和value属性的区别,placeHolder在输入框处入焦点时文字会消失,而value不会。
<!DOCTYPEhtml> <html> <head> <linkrel="stylesheet"href="dijit/themes/claro/claro.css"> <script>dojoConfig={parSEOnLoad:true}</script> <scriptsrc='dojo/dojo.js'></script> <script> require(["dojo/parser","dijit/registry","dojo/on",function(parser,registry,on){ parser.parse(); varBox0=registry.byId("value0Box"); varBox1=registry.byId("value1Box"); Box1.set("value",Box0.get("value")+"modified"); on(Box0,"change",function(){ Box1.set("value",Box0.get("value")+"modified"); }); }); </script> <title>TextBox</title> </head> <bodyclass="claro"> <labelfor="value0Box">AtextBoxwithavalue:</label> <inputid="value0Box"data-dojo-type="dijit/form/TextBox" value="Somevalue" data-dojo-props="intermediateChanges:true"></input> <br> <labelfor="value1Box">AtextBoxsetwithavaluefromtheabovetextBox:</label> <inputid="value1Box" data-dojo-type="dijit/form/TextBox"></input> <br> </body> </html>
--综合应用:
<!DOCTYPEhtml> <html> <head> <linkrel="stylesheet"href="dijit/themes/claro/claro.css"> <script>dojoConfig={parSEOnLoad:true}</script> <scriptsrc='dojo/dojo.js'></script> <script> //loadrequirementsfordeclarativewidgetsinpagecontent require(["dijit/form/NumberTextBox","dijit/form/CurrencyTextBox","dijit/form/TimeTextBox","dijit/form/DateTextBox",function(NumberTextBox,CurrencyTextBox,TimeTextBox,DateTextBox){ varnumber=newNumberTextBox({ value:54,required:true },"number"); number.startup(); varcurrency=newCurrencyTextBox({ value:54775.53,required:true,constraints:{fractional:true},currency:"CNY",invalidMessage:"无效值." },"currency"); currency.startup(); vartime=newTimeTextBox({ constraints:{ timePattern:"HH:mm:ss",clickableIncrement:"T00:15:00",visibleIncrement:"T00:15:00",visibleRange:"T01:00:00" },invalidMessage:"Invalidtime." },"time"); time.startup(); vardate=newDateTextBox({ value:newDate(2011,8,15) },"date"); date.startup(); }); </script> <title>TextBox</title> </head> <bodyclass="claro"> <h1>dijit/form/NumberTextBox,dijit/form/CurrencyTextBox,dijit/form/TimeTextBox,dijit/form/DateTextBox</h1> <div> <labelfor="number">Age:</label> <inputid="number"> </div> <div> <labelfor="currency">AnnualSalary:</label> <inputid="currency"> </div> <div> <labelfor="time">StartTime:</label> <inputid="time"> </div> <div> <labelfor="date">StartDate:</label> <inputid="date"> </div> </body> </html>
结果:
2、 dijit/form/ValidationTextBox
Extends: dijit/form/TextBox,利用required属性指定字段必填,regExp属性指定字段验证规则。
<!DOCTYPEHTML> <htmllang="en"> <head> <Metacharset="utf-8"> <title>Demo:ValidateTextBox</title> <linkrel="stylesheet"href="dijit/themes/claro/claro.css"> <scriptsrc="dojo/dojo.js"data-dojo-config="async:true,parSEOnLoad:true"></script> <styletype="text/css"> label{ display:inline-block; width:140px; } </style> <script> require(["dojo/parser","dijit/form/ValidationTextBox"]); </script> </head> <bodyclass="claro"> <labelfor="zip">Also5-DigitU.S.Zipcodeonly:</label> <inputtype="text"id="zip"name="zip"value="00000"required="true" data-dojo-type="dijit/form/ValidationTextBox" data-dojo-props="regExp:'\\d{5}',invalidMessage:'Invalidzipcode.'"/> </body> </html>
输出:
3、 dijit/form/ComboBox
Extends: dijit/form/ValidationTextBox,dijit/form/ComboBoxMixin。ComBoxBox包含可选值的下拉列表,另外还可以手工输入。
属性 | 属性类别 | 描述 |
autoComplete | Boolean true |
判断是否自动完成用户输入的内容。当值为真时,用户输入部分字符串,ComboBox widget 会把能匹配上的可选值列出,如果光标离开此 widget,会显示第一个匹配的选项值。 |
hasDownArrow | 判断是否现实下拉按钮。 | |
ignoreCase | 判断是否忽略大小写(针对英文的输入)。 | |
pageSize | Integer Infinity |
此属性可以设置下拉列表显示的条数,如果出现多页的情况,会在下拉列表中显示” PrevIoUs choices ”和” More choices ”按钮。用户可以通过点击这两个按钮来查找选项。 |
query | Object {} |
设置查询表达式以过滤’ store ’里的选项。 |
searchAttr | String name |
设置查找的匹配表达式 |
searchDelay | boolean true |
当用户输入内容后到 Dojo 开始查找用户输入值的匹配项之间的间隔时间。 |
store | Object | 数据提供对象的一个引用。 .Dijit 中一般应用 JSON 格式的数据。 |
