3.高级自定义密码验证
前面的验证都是extjs已经提供的,我们也可以自定义验证函数。
//先用Ext.apply方法添加自定义的password验证函数(也可以取其他的名字)
Ext.apply(Ext.form.VTypes,{
password:function(val,field){ //val指这里的文本框值,field指这个文本框组件,大家要明白这个意思
if(field.confirmTo){ //confirmTo是我们自定义的配置参数,一般用来保存另外的组件的id值
var pwd=Ext.get(field.confirmTo); //取得confirmTo的那个id的值
return (val==pwd.getValue());
}
return true;
}
});
//配置items参数
items:[
{
fieldLabel : "密码",
id : "pass1",
},{
fieldLabel : "确认密码",
id : "pass2",
vtype : "password",//自定义的验证类型
vtypeText : "两次密码不一致!",
confirmTo : "pass1",//要比较的另外一个的组件的id
}
]
4.使用正则表达式验证
new Ext.form.TextField({
fieldLabel : "姓名",
name : "author_nam",
regex : /[/u4e00-/u9fa5]/, //正则表达式在/...../之间. [/u4e00-/u9fa5] : 只能输入中文.
regexText : "只能输入中文!",
allowBlank : false //此验证依然有效.不许为空.
