free-jqgrid populate drop down in subgrid

I am having a devil of a time populating a drop down list in a sub-grid. I am using free-jqgrid 4.15.5. I have no issues when populating a drop down in the main grid but it appears that I am having ID issues when trying to get a simular drop down in the subgrid ( grid as a subgrid option) dows anyone know a reference or how to populate the drop down correctly?
my current test function for the drop down is:
function popUsersT() {
alert("subgrid id : " + window.subgrid_id + "\nfound : " + $("#" + subgrid_id).length + "\nrow id : " + window.row_id + "\nfound(row) : " + $("#" + window.row_id).length + "\ndropdown found : " + $("select", "#" + window.row_id).length + "\nsg_tableID: " + $("#" + sg_tableID).html);
var current = $("#" + subgrid_id).jqGrid('getRowData', $("#" + window.subgrid_table_id )[0].p.selrow).TaskValidator;
alert(current);
$.ajax({
url: "/Tasks/getUserList",
datatype: 'json',
mtype: 'Get',
async: false,
success: function (users) {
$("#Task").html("");
$("#Proxy").html("");
$.each(users, function (i, user) {
$("#Task").append(
$('<option></option>').val(user.name).html(user.DisplayName)
);
$("#Proxy").append(
$('<option></option>').val(user.name).html(user.DisplayName)
);
});
$("#Task").prop("disabled", false);
$("#Proxy").prop("disabled", false);
$("#Task").val(current);
$("#Proxy").val(current);
}
});
}
part of my subgrid is:
subGridRowExpanded: function (subgrid_id, row_id) {
var sg_tableID = subgrid_id + "_t";
window.subgrid_id = sg_tableID;
window.row_id = row_id;
window.subgrid_table_id = sg_tableID;
//alert(subgrid_id);
//alert(row_id);
var pager_id = "p_" + sg_tableID;
$("#" + subgrid_id).html("<table id='" + sg_tableID + "' class='scroll'></table><div id='" + pager_id + "' class='scroll'></div>");
jQuery("#" + sg_tableID).jqGrid({
url: "/Home/GetTaskSubList/" + row_id,
I keep playing with the Id values to try to get away from the errors of:
Error: 'subgrid_table_id' is undefined
Error: 'sg_tableID' is undefined
I am sure i am getting lost in trying to make this work, and was hoping this was something easy i am over looking.
thank you for your help

in the end iw as able to get it workign by setting the values:
subGridRowExpanded: function (subgrid_id, row_id) {
var sg_tableID = subgrid_id + "_t";
window.subgrid_id = sg_tableID;
window.row_id = row_id;
window.subgrid_table_id = sg_tableID;
and then referencing the values in the function by:
var currentOwner = $("#" + subgrid_id).jqGrid('getRowData', $("#" + window.subgrid_table_id)[0].p.selrow).Task;
I am not sure i fully understand the why but it does seem to work as needed. thank you

ajax weird bahavior in url after deleting data in browsers cache

I have a C# Webservice which I'm contacting through URL to retrieve data. The Webservice is lying on a local server in our company network. For example: I have a specific function to get street names, the url to webservice is like this :
Request URL:http://10.1.1.32:8080/webportale_ger_webservice.asmx/SelectStreets
This URL is stored in localStorage.
After deleting browsers cache the request URL has changed, which makes absolutly no sense to me:
http://10.1.1.32:8081/nullSelectStreets
The port is wrong and what about that null?
After trying this request several times again, the url value changes to the correct value.
My jQuery ajax Request looks like this:
var UrlToWebservice = window.localStorage.getItem("url_to_webservice");
$(document).on("keyup", "#input_strasse", function () {
var inputStr = $('#input_strasse').val();
var charStr = inputStr.charAt(0).toUpperCase() + inputStr.substr(1);
console.log("buchstabensuppe: ", charStr)
$.ajax({
type: 'POST',
url: UrlToWebservice + 'SelectStreets',
data: { 'charStr': charStr },
crossDomain: true,
dataType: 'xml',
success: function (response) {
$("input_strasse_datalist").empty();
var strassen = new Array;
$(response).find('STRASSE').each(function () {
var strasse = $(this).find('NAME').text();
var plz = $(this).find('PLZ').find('plz').text();
var ort = $(this).find('PLZ').find('ORT').text();
var arstrasse = $(this).find('AR').first().text();
console.log("arstrasse ", arstrasse)
$("#input_strasse_datalist").append('<option data-ar = ' + arstrasse + ' value = "' + strasse + ' (' + plz + ', ' + ort + ')">' + strasse + ' (' + plz + ', ' + ort + ')</option>')
$("#input_plz").val(plz)
$("#input_ort").val(ort)
})
},
error: function () {
window.location.hash = "httperror";
}
})
})
The value in localStorage is: http://10.1.1.32:8080/webportale_ger_webservice.asmx/
What am I doing wrong?
Thanks a lot.

SVG to PNG to AJAX API post

I have a rather large and complex code of SVG that generates using JavaScript and jQuery dynamically based on the pages information.
I then have an AJAX post save.
What am I failing to do to convert this to post the image data properly?
var canvas = $("#canvas")[0];
var string= canvas.toDataURL("image/png");
base64=string.replace("data:image/png;base64,", "");
var rid = kRid || "";
var fileN = " Product " + rid + ".png";
var req = "";
req += "<qdbapi>";
req += "<field fid='323' filename='" + fileN + "'>" + base64 + "</field>";
req += "</qdbapi>";
$.ajax({
type: "POST",
contentType: "text/xml",
dataType: "xml",
processData: false,
//url altered
url: "https://removed.quickbase.com/db/removedDBID?act=API_EditRecord&rid=" + rid,
data: req,
success: function(responce) {
//auto reload page
var str = window.location.href;
setTimeout(function() {
window.location.href = str;
}, 5000);
}
})
The idea came from this snippet of code that I used else ware to get current PNG files and move them:
$.get(url, function(xml) {
var promises = [];
$("record", xml).each(function() {
var url = $("f#9 url", this).text();
xhr.responseType = "arraybuffer";
xhr.onload = function() {
var arrayBuffer = xhr.response;
var base64 = btoa([].reduce.call(new Uint8Array(arrayBuffer), function(p, c) {
return p + String.fromCharCode(c)
}, ''))
var req = "";
req += "<qdbapi>";
req += "<field fid='6' filename='" + name + "'>" + base64 + "</field>";
req += "<field fid='54' >" + Rid + "</field>";
req += "<field fid='44' >" + comment + "</field>";
req += "</qdbapi>";
... then the AJAX post.
I do not have access to do this via PHP.

(Posted on behalf of the OP).
I forgot to add == to mark the end of the file so:
var string= canvas.toDataURL("image/png");
string+="==";
base64=string.replace("data:image/png;base64,", "");
and huzza it works...

Can't Grab Query String in JavaScript

We were provided function getQueryStringVariableByItemID for our project and are using function getData to use a web service for a game's details from a games table. We believe the getData part is working fine since we use a similar POST on another page. Is getQueryStringVariableByItemID not properly grabbing the query string?
We call getData with the body tag of html as onload="getData()". Many thanks in advance!
Code:
<script type="text/javascript">
function getQueryStringVariableByItemID(ItemID) {
//use this function by passing it the name of the variable in the query
//string your are looking for. For example, if I had the query string
//"...?id=1" then I could pass the name "id" to this procedure to retrieve
//the value of the id variable from the querystring, in this case "1".
ItemID = ItemID.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + ItemID + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(window.location.search);
if (results == null)
return "";
else
return decodeURIComponent(results[1].replace(/\+/g, " "));
}
function getData() {
var ItemID = getQueryStringVariableByItemID(ItemID)
$.ajax({
type: "POST",
url: "./WebServiceTry.asmx/GetGameDetails",
data: "{'ItemID': '" + escape(ItemID) + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var data = response.d;
$('#output').empty();
$.each(data, function (index, item) {
var Title = item.Title
var Price = "$" + item.Price
var Year = "Year: " + item.Year
var Developer = "Developer: " + item.Developer
var Platform = "Platform: " + item.Platform
$('#output').append('<li>' + Title + '</li>');
$('#output').append('<li>' + Price + '</li>');
$('#output').append('<li>' + Year + '</li>');
$('#output').append('<li>' + Developer + '</li>');
$('#output').append('<li>' + Platform + '</li>');
$('#output').listview('refresh');
});
},
failure: function (msg) {
$('#output').text(msg);
}
});
}
</script>

The ItemID you are passing in the getData(while calling inside the getData) should be undefined because the function doesnt have that variable.Pass a valid id and it will work fine

what is [object Object]?

why instead giving data(value) of database give me the [object Object]?
var dataObj = $(this).closest('form').serialize();
$.ajax({
type: "POST",
url: url,
data: dataObj,
cache: false,
dataType: 'json',
success: function (data) {
$(".list_name").show().html('');
$(".list_name").append('<p>' + data + '</p>');
$('.list_name p a').click( function(e) {
e.preventDefault();
$('<b>' + b + '، </b><input type="text" name="hotel[]" value="' + b + '" style="border: none; display: none;" />').appendTo($('.auto_box span'));
$(this).remove();
return false;
});
});
results url is:(json_encode()) :
[{"name":"333333"},{"name":"\u0633\u0644"},{"name":"\u0633\u0644\u0627\u0633\u06cc"},{"name":"\u0633\u0644\u0627\u0633\u0633"},{"name":"\u0633\u0644\u0627\u0645"}]
update: full code:
$('.auto_complete').keyup(function () {
var id = '#' + this.id;
var alt = $(id).attr('alt'); var id = $(this).attr('id'); var name = $(this).attr('name');
var url = alt + id + '/' + name;
var dataObj = $(this).closest('form').serialize();
$.ajax({
type: "POST",
url: url,
data: dataObj,
cache: false,
dataType: 'json',
success: function (data) {
$(".list_name").show().html('');
for (i in data) {
var obj = $('' + data[i].name + '');
obj.click(function(e) {
e.preventDefault();
$('<b>' + b + '، </b><input type="text" name="hotel[]" value="' + b + '" style="border: none; display: none;" />').appendTo($('.auto_box span'));
$(this).remove();
return false;
});
var p = $('p');
p.append(obj);
$(".list_name").append(p);
}
},
"error": function (x, y, z) {
// callback to run if an error occurs
alert("An error has occured:\n" + x + "\n" + y + "\n" + z);
}
});
});

data is not a string, but a JSON object, which is basically a Javascript Object. You access it as you would any JS object/array (looks like your result string is an array)
So you can do something like this: data[1].name

data is a list (It is javascript object).
toString( list ) in javascript gives "object Object"
data[0].name will return "333333"
To make a string from a complex object write your own function.

It looks like your Ajax call is returning an array of structures. Each element in the array is a name-value pair. Given that data is an array, the first element is data[0] so you might do something like:
var firstElem = data[0];
var firstName = firstElem.name;
alert("The first name is: " + firstName);
If you want to add all of the names into your html, you would need to loop through the array, each time appending the current element.
If you wanted to show all names, you could do
var names = "";
for (var i=0; i<data.length; i++) {
var elem = data[i];
names = names + elem.name + ", ";
}

I would rewrite it in the following way
var dataObj = $(this).closest('form').serialize();
$.ajax({
type: "POST",
url: url,
data: dataObj,
cache: false,
dataType: 'json',
success: function (data) {
$(".list_name").show().html('');
for (i in data) {
var obj = $('' + data[i].name + '');
obj.click(function(e) {
e.preventDefault();
$('<b>' + b + '، </b><input type="text" name="hotel[]" value="' + b + '" style="border: none; display: none;" />').appendTo($('.auto_box span'));
$(this).remove();
return false;
});
var p = $('p');
p.append(obj);
$(".list_name").append(p);
}
}
});
