struts2 jquery ajax和客户端验证不能正常工作 [英] struts2 jquery ajax and client side validatio not working toghether
问题描述
我使用了 http://struts.jgeppert.com的标准代码段。 /struts2-jquery-showcase/index.action 和 http：// code.google.com/p/struts2-jquery/wiki/Validation 。
但是客户端和ajax服务器端验证不能协同工作。
But the client side and ajax server side validations are not working together.
问题是表单提交没有停止，即使我们 preventDefault 或其他任何事情，也会调用操作。
The problem is form submission does not stop and action gets called even if we preventDefault or do anything else.

function customeValidation(form, errors) {
//List for errors
// alert("in js");
var list = $('#formerrors');
//Handle non field errors
if (errors.errors) {
$.each(errors.errors, function(index, value) {
list.append('<li>'+value+'</li>\n');
});
}
//Handle field errors
if (errors.fieldErrors) {
$.each(errors.fieldErrors, function(index, value) {
var elem = $('#'+index);
if(elem)
{
alert(value[0]);
}
});
}
}
$.subscribe('before', function(event,data) {
var fData = event.originalEvent.formData;
alert('About to submit: \n\n' + fData[0].value + ' to target '+event.originalEvent.options.target+' with timeout '+event.originalEvent.options.timeout );
var form = event.originalEvent.form[0];
if (form.name.value.length < 2) {
alert('Please enter a value with min 2 characters');
**// the event does not stop here if we use ajax validation i.e validate = true, if we remove it then this works.**
event.originalEvent.options.submit = false;
}
});
</script>
</body>
</html>
如果我们使用ajax验证，即event.originalEvenet.options.submit = false并不会停在这里在提交按钮中为true，如果我们删除它，那么这是有效的。**
the event.originalEvenet.options.submit = false does not stop here if we use ajax validation i.e validate = true in submit button, if we remove it then this works.**
推荐答案
好吧，
我在这里查看struts2 jquery插件代码o.validate在struts2中调用validate函数，而设置为false时o.options.submit不调用实际操作。
I looked into struts2 jquery plugin code here o.validate calls validate function in struts2 while o.options.submit when set to false does not calls the actual action.
现在，如果我的客户端验证应该能够阻止ajax验证。
Now if my client side validation is should be able to block ajax validation too.
但是在这里，我无法设置event.originalEvent.validate = false因此ajax验证将始终发生。
But here, I am not able to set event.originalEvent.validate = false hence ajax validation will happen always.
需要修复一下本地库有一个用例，客户端验证必须能够撤销服务器端验证并避免网络呼叫。
Need someway to fix this is native library to have a use case, where client side validation must be able to revoke server side validation and avoid network call.
params.beforeSubmit = function(formData, form, formoptions) {
var orginal = {};
orginal.formData = formData;
orginal.form = form;
orginal.options = formoptions;
orginal.options.submit = true;
s2j.publishTopic(elem, always, orginal);
if (o.onbef) {
$.each(o.onbef.split(','), function(i, topic) {
elem.publish(topic, elem, orginal);
});
}
if (o.validate) {
orginal.options.submit = s2j.validateForm(form, o);
orginal.formvalidate = orginal.options.submit;
if (o.onaftervalidation) {
$.each(o.onaftervalidation.split(','), function(i, topic) {
elem.publish(topic, elem, orginal);
});
}
}
if (orginal.options.submit) {
s2j.showIndicator(indi);
if(!o.datatype || o.datatype !== "json") {
if (o.loadingtext && o.loadingtext !== "false") {
$.each(o.targets.split(','), function(i, target) {
$(s2j.escId(target)).html(o.loadingtext);
});
}
else if (s2j.defaults.loadingText !== null) {
$.each(o.targets.split(','), function(i, target) {
$(s2j.escId(target)).html(s2j.defaults.loadingText);
});
}
}
}
return orginal.options.submit;
};
params.success = s2j.pubSuc(elem, always, o.onsuc, indi, 'form', o);
params.complete = s2j.pubCom(elem, always, o.oncom, o.targets, indi, o);
params.error = s2j.pubErr(elem, always, o.onerr, o.errortext, 'html');
$.each(o.formids.split(','), function(i, fid) {
s2j.log('submit form : ' + fid);
$(s2j.escId(fid)).ajaxSubmit(params);
});
return false;
});
