dojo小例子（8）ValidationTextBox密码校验，两次输入一致性校验

<p>Password: <input type="password"

name="password1"

id="password1"

data-dojo-type="dijit/form/ValidationTextBox"

data-dojo-props="required:true, intermediateChanges:false,

regExp:'[a-zA-Z][a-zA-Z0-9_]{5,15}',

invalidMessage:'以字母开头，字母数字下划线组合，6-16字符'" /></p>

<p>Confirm: <input type="password"

name="password2"

id="password2"

data-dojo-type="dijit/form/ValidationTextBox"

data-dojo-props="required:true, intermediateChanges:false,

validator:confirmPassword,

constraints:{'other': 'password1'},

invalidMessage:'两次输入的密码不相同!'" /></p>

require(['dojo/parser', 'dojo/domReady!'],

function(parser){

parser.parse();

});

function confirmPassword(value, constraints)

{

var isValid = false;

if(constraints && constraints.other) {

var otherInput = dijit.byId(constraints.other);

if(otherInput) {

var otherValue = otherInput.value;

isValid = (value == otherValue);

}

}

return isValid;

}

提示不能为空：

输入数字，会提示必须以字母开头：

两次输入不一致，提示：

后来发现有更简单的写法：

<p>Confirm: <input type="password"

name="password2"

id="password2"

data-dojo-type="dijit/form/ValidationTextBox"

data-dojo-props="required:true, intermediateChanges:false,

validator:function(){return this.value == dijit.byId('password1').value},

invalidMessage:'两次输入的密码不相同!'" /></p>
