I have parent dynamic HTML page with a form and random number of input fields in which I would like to insert predefined data from child help window.
I use Javascript to open child window, where I display possible values, which I send to parent window with a click. That works fine, if I have fixed field names in parent window - via window.opener.document.myFormName.Variable1.value I assign value to Variable1.
But now I have random number of variables, and therefore random names. I can send the name of the variable to my child window, but don't know how to use it, to assign specific data to that variable.
function Izbor(a, b) {
window.opener.document.Vprasalnik.a.value = b;
window.close()
}
b is the value, that I assign, and a is the name of the variable, that I want to assign this value to.
Is this even possible?
Thanks for the help,
Marcel

Hi,
I would like the javascript to show data from getData method (webMethod), when the page loads but when filter the data (categoryPicker control), using webMethod getData2.
This is currently my c# page.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
JavaScriptSerializer jss = new JavaScriptSerializer();
ClientScript.RegisterStartupScript(this.GetType(), "TestInitPageScript",
string.Format("<script type=\"text/javascript\">google.load('visualization','1.0',{{'packages':['corechart','controls']}});google.setOnLoadCallback(function(){{drawVisualization({0},'{1}','{2}','{3}');}});</script>",
jss.Serialize(GetData()),
"Name Example",
"Name",
"Type Example",
"Type Example",
"Type,"));
}
else
{
JavaScriptSerializer jtt = new JavaScriptSerializer();
ClientScript.RegisterStartupScript(this.GetType(), "TestInitPageScript",
string.Format("<script type=\"text/javascript\">google.load('visualization','1.0',{{'packages':['corechart','controls']}});google.setOnLoadCallback(function(){{drawVisualization({0},'{1}','{2}','{3}');}});</script>",
jtt.Serialize(GetData2()),
"Name Example",
"Name",
"Type Example",
"Type Example",
"Type,"));
}
}
[WebMethod]
public static List<Data> GetData()
{
SqlConnection conn = new SqlConnection("#####");
DataSet ds = new DataSet();
DataTable dt = new DataTable();
conn.Open();
var yesterday = DateTime.Today.AddDays(-1);
string cmdstr = "select top 500 Name, [Decimal price],Cover, UploadDate from [dbo].[database] order by UploadDate desc";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
SqlDataAdapter adp = new SqlDataAdapter(cmd);
adp.Fill(ds);
dt = ds.Tables[0];
List<Data> dataList = new List<Data>();
string cat = "";
float val = 0;
string typ = "";
DateTime dat = DateTime.Now;
foreach (DataRow dr in dt.Rows)
{
try
{
cat = dr[0].ToString();
val = Convert.ToInt32(dr[1]);
typ = dr[2].ToString();
dat = (DateTime)(dr[3]);
}
catch
{
}
dataList.Add(new Data(cat, val, typ, dat));
}
return dataList;
}

I am little unsure, how do I go about updating on the javascript side. Could any one provide some guideline or process in what I need to do, please.
function drawVisualization(dataValues, chartTitle, columnNames, categoryCaption) {
if (dataValues.length < 1)
return;
var data = new google.visualization.DataTable();
data.addColumn('string', columnNames.split(',')[0], 'name');
data.addColumn('number', columnNames.split(',')[1], 'price');
data.addColumn('string', columnNames.split(',')[2], 'type');
data.addColumn('datetime', columnNames.split(',')[3], 'date');
for (var i = 0; i < dataValues.length; i++) {
var date = new Date(parseInt(dataValues[i].Date.substr(6), 10));
data.addRow([dataValues[i].ColumnName, dataValues[i].Value, dataValues[i].Type, date]);
}
var dateFormatter = new google.visualization.DateFormat({ pattern: 'dd MM yyyy' });
var line = new google.visualization.ChartWrapper({
'chartType': 'AreaChart',
'containerId': 'PieChartContainer',

'width': 1200,
'height': 500,
'legend': 'none',

},
'chartArea': { 'left': 150, 'top': 100, 'right': 50, 'bottom': 100 },
'tooltip': { isHtml: true }
},
'view': {
'columns': [{

label: data.getColumnLabel(3),
calc: function (dt, row) {
var date = dt.getValue(row, 3);
return dateFormatter.formatValue(date);
}
}, 1, {
type: 'string',
role: 'tooltip',
calc: function (dt, row) {
return 'Name: ' + dt.getValue(row, 0) + ', Price: ' + +dt.getValue(row, 1) + ', Date: ' + +dt.getFormattedValue(row, 3);
}
}]
}
});
var categoryPicker = new google.visualization.ControlWrapper({
'controlType': 'CategoryFilter',
'containerId': 'CategoryPickerContainer',
'options': {
'filterColumnLabel': columnNames.split(',')[3],
'filterColumnIndex': '3',
'ui': {
'labelStacking': 'horizontal',
'allowTyping': false,
'allowMultiple': false,
'caption': categoryCaption,
'label': 'Date',
}
}
});
new google.visualization.Dashboard(document.getElementById('PieChartExample')).bind([categoryPicker], [line]).draw(data);
table.draw(data, { showRowNumber: true });
}
Any help or guidance would be very much appreciated. Thanks in advance.

Need more details inorder to understand your requirement. Can you please clarify little bit more in detail.

Thank you for your response. I would like to be able to call (getData) query when the page loads and show the (getData) query results in a(using 'line method' -- see javascript code) line chart. When I use the data filters in javascript(categoryPicker), I would like to control filters (categoryPicker), to use (getData2) method query to filter the line charts' output.
for example:
when page loads, call query1(select top 100 * from data), then click/mouseover/search on filter(categoryPicker), filter the line chart results using qyery2(select * from data).
I hope the explanation above clarifies my problem.
Any help would be very much appreciated. Thank you for your time and help.

hi
I want to put the script into a php page, then call it with a "includes", but in order to do that I will need to be able to change the code on this line
which wants the link to the image.
$('#puzzle-image').attr('src', 'content/images/avengers.jpg');
because I would like to keep using the same code, from the same php file, with different images, so I need to call for the image, from each page to go in the code above.
it's from this page

I am having a little issue, with getting dates to show up in desired (dd-mm-yyyy) format, however they are displayed as 'NaN Nan' on the line chart x-axis. I have added in a 'parseInt' date format but I am not sure if this is a correct approach.
Please advice. Many thanks for your help and time.

The reason is the value is not a numeric.
miss786 wrote: I have added in a 'parseInt' date format but I am not sure if this is a correct

I think you're getting NAN because you're getting an empty string or null & parsing directly. Just check the result of parseInt("") or parseInt(null)
So check the value before sending to Date function. Debug there.

Apology for the late response. Thank you very much for your feedback. I manage to get the date value pass the parseInt but however, now I am getting a blank screen on the client-end, with the following warning in the console debug of my chrome browser:

That's warning, possibly you're using new jQuery version. Try previous(your project's) version.

Hi,
I am not sure whether this would work, but,
can you try this ?
<input name="date" id="datepicker" disabled="disabled" />
$('#datepicker').datepicker();
For further could you please check this link:-
