RE: Textfield onchange --> handling ajax error response to show action errors

2015-09-02 Thread Christoph Nenning
The documentation about ajax-validation might help you:

http://struts.apache.org/docs/ajax-validation.html


Basically you have to create JSON with 'errors' like this:

http://struts.apache.org/docs/ajax-validation.html#AJAXValidation-Howitworks


And you might use the JavaScript function 
StrutsUtils.showValidationErrors( ) to display them. Of course you must 
include struts utils.js to use that function.

Christoph

MG>this would assume your errors are JSON formatted as:
{"errors": ["Global Error 1", "Global Error 2"],"fieldErrors": {
"field1": ["Field 1 Error 1", "Field 1 Error 2"],"field1": ["Field 2 
Error 1", "Field 2 Error 2"]  }}
MG>

MG>in StrutsUtils.getValidationErrors below if data is POJO return the POJO 
object
MG>otherwise return from position 2 after the /* as seen here
StrutsUtils.getValidationErrors = function(data) {
if (typeof data === "object") {
return data;
}
else {
if (data.indexOf("/* {") === 0) {  // /* { must be in position 0
return eval("( " + data.substring(2, data.length - 2) + " )");
} else {
return null;
}
}
};

MG>later on in StrutsUtils.showValidationErrors johann looks for the enclosing 
Div as seen here:
var enclosingDiv = findWWGrpNode(elem); // find wwgrp div/span
MG>so if your jsp contains NO div...then this wont work

MG>I always have 2 div tags in jsp:

MG>one for normal output response with green color:
WORKS

MG>one for error output response with red color:
DOESNT 
WORK

MG>in postValidation method up to receiving the text
function postValidation(request) { var form = $('form');   //clear 
previous validation errors, if any StrutsUtils.clearValidationErrors(form); 
  //get errors from response var text = request.responseText;
//this is where I would test text for error response or normal response
 if(text.indexOf("error")!=-1) 
{
if(isJson(text) == "false")  error.innerHTML = text; //normal error text
else error.innerHTML = JSON.parse(text);  //JSON error text
}
else 
{
 if(isJson(text) == "false") ok.innerHTML = text;   //normal response text
 else ok.innerHTML = JSON.parse(text);  //JSON response text
 form.submit();
}
} //end postValidation

function isJson( jsonData )
if (typeof jsonData == 'string') 
{

  if (! /^[\[|\{](\s|.*|\w)*[\]|\}]$/.test(jsonData)) 
  {
return "true";
}

}

try 
{
jsonData = $.parseJSON(jsonData);
} 
catch (e) 
{
return "false";
} //any exception will return false
return "true";//valid JSON formatted data 
) //end isJson

Re: Textfield onchange -- handling ajax error response to show action errors

s:actionerror/ works on server side but JavaScript works on client
side - it isn't possible to join them. You can only mimic its
behaviour by adding the same html structure as s:actionerror/ does.

   text-field onchange --- making ajax call.


 onsucess --- everything works fine as needed


 on failure -  like user entered wrong data --- How to show the error 
 messages in jsp. I added fieldError but not sure how to show it in jsp with 
 the ajax stuff.

 In jsp
 s:actionerror/
 

 script$.ajax({

 url: 
 ajax/retrivexxxAJAXAction.action+?jsonRequestdata=+JSON.stringify(json),
 type: 'POST',
 dataType: 'json',


 success:function(response){
