Ext验证汇总

1.验证输入框长度：一个汉字等于两个字符问题

validator：function(){
?????? var str = Ext.util.Format.trim(news.getValue());
?????? var size = 0;
?????? for(var i=0;i<str.length;i++){
????? ??? ?var code = str.charCodeAt(i);
????? ??? ?if(code > 255){
????? ??? ??? ?size += 2;
????? ??? ?}else{
????? ??? ??? ?size += 1;
????? ??? ?}
????? ??? ?if(size > 30){
????? ??? ??? ?news.invalidText = '长度不能超过30！';
????? ??? ??? ?news.focus();
????? ??? ??? ?return false;
????? ??? ?}else{
????? ??? ??? ?return true;
????? ??? ?}
?????? }

}

2.只能输入中文、字母、数字、英文逗号、英文句号！

?regex:/^([\u0391-\uFFE5]|[a-zA-Z]|\d[-,._])*$/,

?regexText: '只能输入中文、字母、数字、英文逗号、英文句号',

??????????????? Ext.get('notic').dom.innerHTML = news.viewTi;
????????? }
