I need to call an ASPX page from MVC view through below JavaScript code, also need to pass some parameter as query string,
function OpenTest() {
var width = (screen.availWidth - 700).toString();
var height = (screen.availHeight - 100).toString();
var param1 = "Test";
var baseUrl = '#Url.Content("~/Test/Test.aspx?")';
window.open(baseUrl + "param1=" + param1);
}
In ASPX page,
if(!string.IsNullOrWhiteSpace(Request.QueryString["param1"]))
{
string s1 = Request.QueryString["param1"];
}
I am able to call ASPX page and read parameter value by above code, but when I add other property of "window.open", I am not able to read query string, question is where should I place below property in above code so that I can also read query string value in ASPX page,
"mywindow", "width=" + width + ",height=" + height + ",toolbar=no,location=no,directories=yes,status=no," +
"menubar=no,scrollbars=yes,copyhistory=yes,resizable=yes" + ",screenX=0,screenY=0,left=0,top=0"
The syntax for window.open() is:
window.open('url/for/page/here.aspx', 'targetName', 'options');
The targetName can be "_self", "_blank", "_parent", just like any target attribute for links, or have an identifier to name the window, so you can reuse the window when openning with the same name.
When you calll window.open() with any option to restrict the window, like width=100 it assumes that all the other have to be disabled, so you don't have to put the properties you want to disable.
Fixing your options would be:
window.open(baseUrl + "param1=" + param1,
"mywindow",
"width=" + width + ",height=" + height + ",directories=yes,scrollbars=yes,copyhistory=yes,resizable=yes,screenX=0,screenY=0,left=0,top=0");
Another thing to note is that all options have to be separated by comas, without spaces. Some browsers ignore/missinterpret options with spaces.
Also, don't forget to escape the variables to pass with the url.

I am trying to append rows to a table using an array called searchResults. Everything works as expected until I introduce the jQuery UI dialog box. The problem is I need a new dialog box for each row in the first column. I'm pretty new to all of this so I'm pretty sure I'm using the index incorrectly at times. This is just to give you an idea of what I'm trying to accomplish. Any ideas how to do this correctly?
for (var i = 0; i < searchResults.length; i++)
{
$('#patientFileDialog[i]').dialog();
$'#openPFDialog[i]').click(function() {
$('#patientFileDialog[i]').dialog('open');
});
var dialog[i] = $(`<div id="patientFileDialog[i]" title="Patient File">${searchResults[i].patientWebLink}</div>`);
body.append('<tr>'+
`<td><button id="openPFDialog[i]">Click Here</button></td>` +
`<td>${searchResults[i].patientFirstName}</td>` +
`<td>${searchResults[i].patientLastName}</td>` +
`<td>${searchResults[i].patientDateOfBirth}</td>` +
`<td>${searchResults[i].patientDataPulseID}</td>` +
`<td>${searchResults[i].patientLaserFicheID}</td>` +
'</tr>')
}
After looking at your code a bit more I think I can see what you are trying to do. Working JSFiddle, with some faked searchResults so we can see it in action.
There are a few problems with the code in your question:
Using selectors like $('#patientFileDialog[i]') and $'#openPFDialog[i]') will try to match elements on the page with those IDs. AFAICT those don't actually exist yet, you are trying to create them.
var dialog[i] = ... sets up some divs as strings, but those are never added to the page;
As I mentioned in my comment, there are some syntax errors, maybe just typos and mixed up formatting here on SO;
Here's an updated version of the code. Notable changes:
Instead of adding an event handler for every individual openPFDialog button, it is better practice to add just one which matches them all. That single handler can then work out which button was clicked, and take the right action for just that one, not all of them. In this case if you have all your buttons use IDs that match openPFDialog-X, where X is a number, you can target anything matching that pattern (using a starts with selector, and find the X by removing the openPFDialog- part with replace.
There's an added complication with the above though. Selectors parsed at page load will only match elements that exist at that time. In this case, you're adding new elements to the page, and a selector defined at page load won't match them. The solution is to select instead some parent element which does exist at page load, and filter. This is called event delegation (search for the paragraph starting with "Delegated event handlers").
Working from what you have, I am guessing the patientFileDialogs you create should be placed inside some parent element which is not displayed on the page? That's what I've done.
Here's the code (and working JSFiddle):
var dialog, i;
// Single click handler for anything that starts with "openPFDialog-".
// Since those elements don't exist on the page yet, we need to instead
// select a parent object, say the body, and filter for clicks on our
// elements starting with our pattern
$('body').on('click', '[id^=openPFDialog]', function() {
// We need to find the "i"
i = $(this).attr('id').replace(/openPFDialog-/,'');
console.log('clicked on id', i);
$('#patientFileDialog-' + i).dialog();
});
for (var i = 0; i < searchResults.length; i++) {
// Create a new div with ID like "patientFileDialog-1", using the current
// search result
dialog = $('<div id="patientFileDialog-' + i + '" title="Patient File">' + searchResults[i].patientWebLink + '</div>');
// Add it to the page. I've use a div with ID dialogs which is hidden
$('#dialogs').append(dialog);
$('table').append('<tr>'+
'<td><button id="openPFDialog-' + i + '">Click Here</button></td>' +
'<td>' + searchResults[i].patientFirstName + '</td>' +
'<td>' + searchResults[i].patientLastName + '</td>' +
'<td>' + searchResults[i].patientDateOfBirth + '</td>' +
'<td>' + searchResults[i].patientDataPulseID + '</td>' +
'<td>' + searchResults[i].patientLaserFicheID + '</td>' +
'</tr>');
}
Update
One last suggestion - manipulating the DOM by adding/removing elements is slow. If you need to do that for each element in an array, it is best to avoid actually adding your content on each iteration, and rather just build up a string. Then once you're done iterating, just add the big single string, so you're chaning the DOM just once. Here's the basic changes needed to do that:
// Add some new variables to hold our big strings
var dialog, dialogs, row, rows, i;
// ... your code ...
for (var i = 0; i < searchResults.length; i++) {
// Create the dialog ...
dialog = ...
// Append it to our big string of all dialogs
dialogs += dialog;
// Same approach for rows
row = '<tr>'+ ... all that stuff
rows += row;
}
// Finished iterating, nothing added to DOM yet. Do it all at once::
$('#dialogs').append(dialogs);
$('table').append(rows);
Here is what I finally ended up having to do:
$(document).ready(function(){
if ($('[attr="searchResultsJson"]').length)
{
$('.approval-outer-wrap').prepend(drawTable());
$('.approval-outer-wrap').append('<div id="result-details" title="Search Result Detail"><p></p></div>')
}
$('body').on('click', '[id^=openPFDialog]', function() {
var result = $(this).parents('tr').data('result');
$('#result-details p').html(result.patientFirstName);
$('#result-details').dialog();
});
});
function drawTable(){
var table = $('<table id="search-results" />');
var header = $('<thead />');
table.append(header);
header.append('<tr><th>Patient File</th><th>First Name</th><th>Last Name</th><th>Date of Birth</th><th>Data Pulse ID</th><th>Laserfiche ID</th></tr>');
var body = $('<tbody />');
table.append(body);
var json = $('[attr="searchResultsJson"] [type="text"]').text();
var searchResults = JSON.parse(json);
for (var i = 0; i < searchResults.length; i++) {
body.append(`<tr data-result='${JSON.stringify(searchResults[i])}'>`+
`<td><button id="openPFDialog-` + i + `">🔍</button></td>` +
`<td>${searchResults[i].patientFirstName}</td>` +
`<td>${searchResults[i].patientLastName}</td>` +
`<td>${searchResults[i].patientDateOfBirth}</td>` +
`<td>${searchResults[i].patientDataPulseID}</td>` +
`<td>${searchResults[i].patientLaserFicheID}</td>` +
'</tr>');
}
return table;
}
Consider the following code.
function showPatientDialog(cnt){
$("#patient-file-dialog").html(cnt).dialog("open");
}
var d = $("<div>", {
id: "patient-file-dialog",
title: "Patient File"
})
.appendTo("body")
.dialog({
autoOpen: false
});
$.each(searchResults, function(i, result) {
var row = $("<tr>").appendTo(body);
$("<td>").appendTo(row).html($("<button>", {
id: "open-pdf-dialog-" + i
}).click(function() {
showPatientDialog(result.patientWebLink);
}));
$("<td>").appendTo(row).html(result.patientFirstName);
$("<td>").appendTo(row).html(result.patientLastName);
$("<td>").appendTo(row).html(result.patientDateOfBirth);
$("<td>").appendTo(row).html(result.patientDataPulseID);
$("<td>").appendTo(row).html(result.patientLaserFicheID);
});
How can I write
var releaseName = $('#SelectedReleaseId option:selected').text()
var templateName = $('#SelectedTemplateId option:selected').text()
this:
$("#TestplanName").text(releaseName + '-' + templateName + '-' + '#Model.UserId' + '-' + '#Model.CreatedAt');
into:
$("#TestplanName").text( '#string.Format("{0}-{1}-{2}-{3}",releaseName,templateName,#Model.UserId,#Model.CreatedAt)');
The releaseName and templateName are unknown...
You can't.
You're trying to mix client-side variables – which only exist in Javascript on the client – with server-side code.
Instead, you can use a Javascript equivalent of string.Format.
I have a page with a text area for title input and body input.
Saving a text file with those things is easy, the question is, how can I make the file to be named after whatever was placed in the title input?
I tried this:
#{
var result = "";
if (IsPost)
{
var title = Request["title"];
var body = Request["body"];
var filedata = title + "," + body + Environment.NewLine;
var dataFile = Server.MapPath("/App_Data/Request["title"]");
File.WriteAllText(#dataFile, filedata);
result = "Information saved.";
}
}
(Note that var title = Request["title"]; means that its requesting from a text input named "title"). What I want to get is that the input will also be the name of the file its saving.
But it seems that this area:
var dataFile = Server.MapPath("/App_Data/Request["title"]");
is not the correct way.
What is the correct way to do it?
Couple of pointers; firstly this sort of logic should be in a Controller, not in a View. Your Views are supposed to display information about your model, your Controllers carry out operations.
Secondly, the following should do the trick (in a Controller!):
[HttpPost]
public ActionResult SaveFile(string title, string body)
{
var fileData = title + "," + body + Environment.NewLine;
var fileSavePath = Path.Combine(
Server.MapPath("~/TextFiles"),
title.Replace(" ", "_") + ".txt");
File.WriteAllText(fileSavePath, fileData);
return this.RedirectToAction("SaveSuccessful");
}
Of note:
Server.MapPath("~/TextFiles") gives you the path to a TextFiles directory in the root of your web application where the files will be stored.
I've replaced spaces in the title which has been input with underscores.
This method redirects the user to an Action named SaveSuccessful on the same Controller
Of course you need error handling and all sorts of other things in there, but hopefully that helps.
I have a view that accepts 2 string parameters and 2 date values. User hits search button and they get filtered output to the screen. This all works perfectly well until a user inputs a string with a space. i.e. they can search for 'waste' but not 'waste oil'.
Interestingly, in the latter, the parameter is ok from Javascript before the call is made. But on entering the controller code it goes form being 'waste oil' on client to 'waste'. When this happens the other parameters get set to NULL crashing the system.
I've tried replacing the spaces if present with '#' character then stripping out and putting back in ' ' on the controller side. This is a messy fudge and only appears to work with one parameter.
There must be a simple explanation for this parameter data loss, any comments much appreciated
Not sure a code example is needed but here it is anyway if it help:
My controller header :
public ActionResult IndexSearch(int? page, string searchText,string searchTextSite,string StartDate,string EndDate)
{
My HTML Javascript :
function Search(sSearchText,sSite) {
sSearchText = sSearchText.toString().replace(" ", "#");
sSite = sSite.toString().replace(" ", "#");
debugger;
alert($("#AbsolutePath").val() + "Waste.mvc/IndexSearch?searchText=" + sSearchText + "&searchTextSite=" + sSite + "&StartDate=" + $('#StartDate').val() + "&EndDate=" + $('#EndDate').val());
$("#ResultsList").load($("#AbsolutePath").val() + "Waste.mvc/IndexSearch?searchText=" + sSearchText + "&searchTextSite=" + sSite + "&StartDate=" + $('#StartDate').val() + "&EndDate=" + $('#EndDate').val(),
function() {
$('#LoadingGif').empty();
});
$('#LoadingGif').empty().html('<img src="' + $("#AbsolutePath").val() + 'Content/images/ajax-loader.gif" alt="Loading image" />');
}
You are not URL encoding your parameters when sending the AJAX request because you are using string concatenations when building the url. You could use the following technique in order to have properly encoded values:
var url = $('#AbsolutePath').val() + 'Waste.mvc/IndexSearch';
var data = {
searchText: sSearchText,
searchTextSite: sSite ,
StartDate: $('#StartDate').val(),
EndDate: $('#EndDate').val()
};
$('#ResultsList').load(url, data, function() {
$('#LoadingGif').empty();
});
Now you will get correct values on the server.
I want to make the following :
1. I have the following formatter function:
function ActionDescriptionFormatter(cellval, opts, rwdat, _act) {
var str = "<a border='0' style='text-decoration: none;' href='/Admin/IdeaDescription?id=" + cellval + "' title='Description'><img src='/images/aico_descr.png' alt='Description' border='0' /></a>";
return str;
}
I want to add also current pagenumber to url.
I want to set page of grid if It's passed via url
How to do it?
