How can I hide the parameters of this URL? - html

I have a ajax call in my javascript and its returning some response as json and redirecting the json values to another jsp page.. in the redirected jsp page, am getting the whole json in the url tab.. how to avoid that...
here is my ajax call in js file...
var cols="PRIORITY,USER_ID,PARTICIPANT_TYPE,CREATION_DATE,ASSIGN_TO_USER_DATE,START_WORK_DATE,DUE_DATE,OPERATION,ORDER_VK,SENDER_TYPE,SENDER_ID,ORDER_ID,FLAGS";
var ioArgs = {
url: "./DynamicDBServlet",
content: { TABLE_NAME:'CWPWORKLIST',WHERE_CONDN:cond,COLUMNS:cols},
handleAs: "json",
load: function(response) {
alert("new "+new String(response));
window.location.href = "worklist.jsp?PRIORITY="+response;
},
error: function(error) {
alert("An unexpected error occurred: " + error);
}
};

Replace this line:
window.location.href = "worklist.jsp?PRIORITY="+response;
with:
openWindowWithPost("worklist.jsp",'height=300px,width=300px,top=200px,left=500px,scrollbars=no,sizable=yes,toolbar=no,statusbar=no','title',param);
and then have the below function:
function openWindowWithPost(url, windowoption, name, params)
{
var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", url);
form.setAttribute("target", name);
var input = document.createElement('input');
input.type = 'hidden';
input.name = "PARAM";
input.value = params;
form.appendChild(input);
/*for (var i in params) {
if (params.hasOwnProperty(i)) {
var input = document.createElement('input');
input.type = 'hidden';
input.name = i;
input.value = params[i];
form.appendChild(input);
}
}*/
document.body.appendChild(form);
window.open(url, name, windowoption);
//alert("inside openpost");
form.submit();
document.body.removeChild(form);
}
and read the values to worklist.jsp using the name PARAM......

You are now using GET to send your PRIORITY variable. Use POST!
You will have to create a form consisting of a single hidden input, put response in the value attribute of said input and submit the form having it's action point to your worklist.jsp.

How to hand an object from backend to frontend

I try to create a Web App. Therefor I have to pass an Object from the backend to the HTML-Script. I tried a lot of possibilites but nothing worked.
Backend
function searchMain (allSeaVal) {
var headCon = DbSheet.getRange(1, 1, 1, DbSheet.getLastColumn()).getValues();
var bodyCon = DbSheet.getRange(valRow, typesCol, 1, DbSheet.getLastColumn()).getValues();
var Con = {
headline: headCon,
values: bodyCon
};
var tmp = HtmlService.createTemplateFromFile('page_js');
tmp.Con = Con.map(function(r){ return r; });
return tmp.evaluate();
}
HTML
<script>
function searchValues() {
var allSeaVal = {};
allSeaVal.seaType = document.getElementById('valSearchTyp').value;
allSeaVal.seaVal = document.getElementById('HSearchVal').value;
google.script.run.searchMain(allSeaVal);
Logger.log(Con);
}
<script/>
I want to use the information in "Con" in the Website. The script-code is stored in the file "page_js.
I don´t know why but I can´t pass the information into the frontend.
In your html interface you have to use the success and failure handler in your google.script.run.
Code will looks like
google.script.run
.withSuccessHandler(
function(msg) {
// Respond to success conditions here.
console.log('Execution successful.');
})
.withFailureHandler(
function(msg) {
// Respond to failure conditions here.
console.log('Execution failed: ' + msg, 'error');
})
.searchMain(allSeaVal);
Do not hesitate to check the documentation : https://developers.google.com/apps-script/guides/html/communication

I solved my problem with your help. Thank you so much. I struggled with this many days.
My solution is the code below.
Backend
function searchMain (allSeaVal) {
var typesCol = searchTypesCol(allSeaVal.seaType);
var valRow = searchRow(allSeaVal.seaVal, typesCol);
var headCon = DbSheet.getRange(1, 1, 1, DbSheet.getLastColumn()).getValues();
var bodyCon = DbSheet.getRange(valRow, typesCol, 1, DbSheet.getLastColumn()).getValues();
var Con = {
headline: headCon,
values: bodyCon
};
return Con;
}
HTML
function searchValues() {
var allSeaVal = {};
allSeaVal.seaType = document.getElementById('valSearchTyp').value;
allSeaVal.seaVal = document.getElementById('HSearchVal').value;
google.script.run
.withSuccessHandler(
function(Con) {
console.log(Con + 'success');
})
.withFailureHandler(
function(Con) {
console.log(Con + 'failure');
})
.searchMain(allSeaVal);
}

Pass a parameter from client-side to server side and get result

I knows it sounds basic but I can't seem to get it right. I'm trying to get a data from the API but it needs a parameter in order to obtain the data. How can I pass the parameter and get the result which is a JSON array
$(function() {
var proxy = 'http://192.168.1.126/lms-dev-noel/proxy.php';
var endpoint = 'account/';
var rt = 'GET';
var url = proxy+'?endpoint='+endpoint+'&rt='+rt;
var param = {
'lastsyncdate' : '2016-12-06'
};
$.get(url, function(param) {
console.log('Success');
});
});
ways to achieve this :
using jQuery.ajax() method :
var proxy = 'http://192.168.1.126/lms-dev-noel/proxy.php';
var endpoint = 'account/';
var url = proxy+'?endpoint='+endpoint+'&rt='+rt;
var method = 'GET';
var params = {
'lastsyncdate' : '2016-12-06'
};
$.ajax({
url: url,
type: method, //send it through get method
data: params,
success: function(response) {
//Do Something
},
error: function(xhr) {
//Do Something to handle error
}
});
using jQuery.get() method :
var proxy = 'http://192.168.1.126/lms-dev-noel/proxy.php';
var endpoint = 'account/';
var url = proxy+'?endpoint='+endpoint+'&rt='+rt;
var method = 'GET';
var params = {
'lastsyncdate' : '2016-12-06'
};
$.get(url, params, function(res) {
console.log(res);
});
I just pass parameters as name value pairs like so...
$.get(
"yoururl.php",
{ color: "red", size: "small" }, // your params go here as name / value pairs
function(response){
console.log(response);
}
);

Uncaught TypeError: Cannot read property 'pageSize' of undefined

Iam trying to apply paging to slickgrid and it shows an error in slick.pager.js as title in console and my code is
var jqxhr = $.getJSON('http://localhost:50305/Service1.svc/json/EmployeeDetails', function (data) {
dataView = new Slick.Data.DataView();
dataView.setItems(data, "EmpId");
dataView.setPagingOptions({ pageSize: 4 });
grid = new Slick.Grid("#teamGrid", dataView.rows, columns, options);
var pager = new Slick.Controls.Pager(dataView, grid, $("#pager"));
dataView.onPagingInfoChanged.subscribe(function (e, pagingInfo) {
alert("hi");
var isLastPage = pagingInfo.pageNum == pagingInfo.totalPages - 1;
var enableAddRow = isLastPage || pagingInfo.pageSize == 0;
var options = grid.getOptions();
if (options.enableAddRow != enableAddRow) {
grid.setOptions({ enableAddRow: enableAddRow });
}
});
dataView.onRowCountChanged.subscribe(function (args) {
grid.updateRowCount();
grid.render();
});
Try this:
dataView.beginUpdate();
dataView.setItems(data, "EmpId");
dataView.endUpdate();
dataView.setPagingOptions({ pageSize: 4 });
grid = new Slick.Grid("#teamGrid", dataView, columns, options);
The code doesn't really even make sense.
The line
var jqxhr = $.getJSON('http://localhost:50305/Service1.svc/json/EmployeeDetails', function (data) {
is not well formed. There should be a function body and a closing brace.
The variable jqxhr is not used anywhere. Why does this line even exist ?
`pagesize=10`
let pagesizealt
if(!this.paginator){
pagesizealt=this.pagesize.toString()
}
else{
pagesizealt=this.paginator.pageSize
}`
u have to check for paginator to initialize after initializtion provide the value of pageSize

Couldn't make ASPJAX working

I want to make a demo on how to combine ASP and AJAX. I have found snippets from http://www.aspjax.com and implemented it in my project. However, the text that should be displayed cannot be output properly.
Here's the code. Basically the same as the one in the original:
In index.asp
<script language="javascript" type="text/javascript">
/** XHConn - Simple XMLHTTP Interface - bfults#gmail.com - 2005-04-08 **
** Code licensed under Creative Commons Attribution-ShareAlike License **
** http://creativecommons.org/licenses/by-sa/2.0/ **/
function XHConn()
{
var xmlhttp, bComplete = false;
try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }
catch (e) { try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }
catch (e) { try { xmlhttp = new XMLHttpRequest(); }
catch (e) { xmlhttp = false; }}}
if (!xmlhttp) return null;
this.connect = function(sURL, sMethod, sVars, fnDone)
{
if (!xmlhttp) return false;
bComplete = false;
sMethod = sMethod.toUpperCase();
try {
if (sMethod == "GET")
{
xmlhttp.open(sMethod, sURL+"?"+sVars, true);
sVars = "";
}
else
{
xmlhttp.open(sMethod, sURL, true);
xmlhttp.setRequestHeader("Method", "POST "+sURL+" HTTP/1.1");
xmlhttp.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");
}
xmlhttp.onreadystatechange = function(){
if (xmlhttp.readyState == 4 && !bComplete)
{
bComplete = true;
fnDone(xmlhttp);
}};
xmlhttp.send(sVars);
}
catch(z) { return false; }
return true;
};
return this;
}
// doAJAXCall : Generic AJAX Handler, used with XHConn
// Author : Bryce Christensen (www.esonica.com)
// PageURL : the server side page we are calling
// ReqType : either POST or GET, typically POST
// PostStr : parameter passed in a query string format 'param1=foo&param2=bar'
// FunctionName : the JS function that will handle the response
var doAJAXCall = function (PageURL, ReqType, PostStr, FunctionName) {
// create the new object for doing the XMLHTTP Request
var myConn = new XHConn();
// check if the browser supports it
if (myConn) {
// XMLHTTPRequest is supported by the browser, continue with the request
myConn.connect('' + PageURL + '', '' + ReqType + '', '' + PostStr + '', FunctionName);
}
else {
// Not support by this browser, alert the user
alert("XMLHTTP not available. Try a newer/better browser, this application will not work!");
}
}
// launched from button click
var getMessage = function () {
// build up the post string when passing variables to the server side page
var PostStr = "";
// use the generic function to make the request
doAJAXCall('ajaxtest.asp', 'POST', '', showMessageResponse);
}
// The function for handling the response from the server
var showMessageResponse = function (oXML) {
// get the response text, into a variable
var response = oXML.responseText;
// update the Div to show the result from the server
document.getElementById("responseDiv").innerHTML = response;
};
</script>
<body>
<button onclick="javascript:getMessage();">Get Message From Server</button>
<div id="responseDiv">Original Text</div>
</body>
So, the code tells it to replace the Original Text in the div with the one in ajaxtest.asp
In ajaxtest.asp
<%# Language=VBScript %>
Response.Write "The Server time is " & Now()
The problem is when I click the button Get Message From Server, the stuff in ajaxtest.asp is rendered as plain text, but not in ASP. How to fix this? Is it because of the extension used is wrong?
EDIT: by plain text I mean exactly as Response.Write "The Server time is " & Now()
You probably want the contents of your ASP page to be:
<%# Language=VBScript %>
The Server time is <%=Now()%>

Parallel form submit and ajax call

I have a web page that invokes long request on the server. The request generates an excel file and stream it back to the client when it is ready.
The request is invoked by creating form element using jQuery and invoking the submit method.
I would like during the request is being processed to display the user with progress of the task.
I thought to do it using jQuery ajax call to service I have on the server that returns status messages.
My problem is that when I am calling this service (using $.ajax) The callback is being called only when the request intiated by the form submit ended.
Any suggestions ?
The code:
<script>
function dummyFunction(){
var notificationContextId = "someid";
var url = $fdbUI.config.baseUrl() + "/Promis/GenerateExcel.aspx";
var $form = $('<form action="' + url + '" method="POST" target="_blank"></form>');
var $hidden = $("<input type='hidden' name='viewModel'/>");
$hidden.val(self.toJSON());
$hidden.appendTo($form);
var $contextId = new $("<input type='hidden' name='notifyContextId'/>").val(notificationContextId);
$contextId.appendTo($form);
$('body').append($form);
self.progressMessages([]);
$fdbUI.notificationHelper.getNotifications(notificationContextId, function (message) {
var messageText = '';
if (message.IsEnded) {
messageText = "Excel is ready to download";
} else if (message.IsError) {
messageText = "An error occured while preparing excel file. Please try again...";
} else {
messageText = message.NotifyData;
}
self.progressMessages.push(messageText);
});
$form.submit();
}
<script>
The code is using utility library that invokes the $.ajax. Its code is:
(function () {
if (!window.flowdbUI) {
throw ("missing reference to flowdb.ui.core.");
}
function NotificationHelper() {
var self = this;
this.intervalId = null;
this.getNotifications = function (contextId, fnCallback) {
if ($.isFunction(fnCallback) == false)
return;
self.intervalId = setInterval(function() {
self._startNotificationPolling(contextId, fnCallback);
}, 500);
};
this._startNotificationPolling = function (contextId, fnCallback) {
if (self._processing)
return;
self._processing = true;
self._notificationPolling(contextId, function (result) {
if (result.success) {
var message = result.retVal;
if (message == null)
return;
if (message.IsEnded || message.IsError) {
clearInterval(self.intervalId);
}
fnCallback(message);
} else {
clearInterval(self.intervalId);
fnCallback({NotifyData:null, IsEnded:false, IsError:true});
}
self._processing = false;
});
};
this._notificationPolling = function (contextId, fnCallback) {
$fdbUI.core.executeAjax("NotificationProvider", { id: contextId }, function(result) {
fnCallback(result);
});
};
return this;
}
window.flowdbUI.notificationHelper = new NotificationHelper();
})();
By default, ASP.NET will only allow a single concurrent request per session, to avoid race conditions. So the server is not responding to your status requests until after the long-polling request is complete.
One possible approach would be to make your form post return immediately, and when the status request shows completion, start up a new request to get the data that it knows is waiting for it on the server.
Or you could try changing the EnableSessionState settings to allow multiple concurrent requests, as described here.
