ext ajax validator全表单字段重复校验处理

basedev.baseSite.uniqueSiteName=function(field){
if(!field){
return true;
}

var editBaseSiteInfoForm = Ext.getCmp(basedev.baseSite.EDIT_BASE_SITE_FORM_ID);

var siteCode = editBaseSiteInfoForm.getForm().findField("siteCode").getValue();
var paramsObj = {siteCode : siteCode, siteName : field, state : editBaseSiteInfoForm.getOperatorType()};

var valid = false;
Ext.Ajax.request({
url : basedev.realPath(‘uniqueCheckBySiteName.do‘),
params: paramsObj,
async : false,
success : function(response) {
var result = Ext.JSON.decode(response.responseText);
if(result.success){
if(result.data == 0){
valid = true;
}
}else{
Ext.ux.Toast.msg(‘提示‘, result.msg);
}
},
failure : function(response) {
Ext.ux.Toast.msg(‘提示‘,response.responseText, ‘error‘);
}
});

if(valid){
return true;
}
return ‘该门店名称已存在‘;

}; 
控件使用blur替代 validator
listeners:{
‘blur‘:function(field){
var uniqueSiteName = basedev.baseSite.uniqueSiteName(field.rawValue);
if(uniqueSiteName!=true) {
field.markInvalid(uniqueSiteName);
}
}
}

/*****************提交表单时ajax校验再走一次 start*****************/
var uniqueSiteName=basedev.baseSite.uniqueSiteName(baseSiteForm.findField(‘siteName‘).getValue());
if(uniqueSiteName!=true){
baseSiteForm.findField(‘siteName‘).markInvalid(uniqueSiteName);
return;
}/*****************提交表单时ajax校验再走一次 end*****************/
