前台编码验证

listeners:{
'blur' : function(){
var new_ranks_code = fsf516.findById('RANKS_CODE_516').getValue();
alert(new_ranks_code)
Ext.Ajax.request({
url : '/bjglweb/ws/expert/IExpertInfoService/getValidate',
method : 'POST',
timeout : 30000,
params : {'new_ranks_code':new_ranks_code},
success : succMaterialRankFn,
failure : failMaterialRankFn

});



// for(var i = 0 ;i<ransk_Code_list.length;i++){
// if(ransk_Code_list[i]==(new_ranks_code)){
// Ext.Msg.alert('提示','该编号已存在，请重新输入');
// fsf516.findById('RANKS_CODE_516').setValue('');
// }
// }


}

}



后台需要转换一下


try {
params = java.net.URLDecoder.decode(params, "UTF-8");
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

String new_ranks_code=com..getParameter("new_ranks_code",
params);
