Using Jquery To Check If A URL Is Valid?

May 7, 2010

A long running background process creates a text file to indicate the completion of the process. From the frontend, I'd need to check every few seconds if the text file has been created or not.

I am doing this check from http://DomainA.com However the file is created in http://DomainB.com/Mytext.txt

write a jquery script that checks for a file across domain?

PS: Currently, I am doing a ajax postback that executes a WebMethod in ASP.NET that creates HttpWebRequest. This works functionally, but I have major performance problems. So, I need a light weight way of finding if a URL is valid or not.

Check ReturnUrl Is Valid Before Redirecting?

Feb 19, 2010

I'm using ASP.NET Membership and Form Authentication and before redirecting to the returnURL I wanted to validate it. For those unfamiliar with the workflow, basically if you request a page that requires that you are authenticated, you are redirected to a login page. In the URL string you'll see a parameter called returnURL, e.g. [URL]

Whether you use this in a redirect such as Response.Redirect(returnURL) or indirectly through the FormsAuthentication.RedirectFromLoginPage method, it passes without validating returnURL.

FormsAuthentication.RedirectFromLoginPage does have a security check that it is isn't leaving the domain, but that still doesn't stop someone from putting enough random characters to cause an error.

I tried using System.IO.File.Exists(Server.MapPath(returnURL)) but given enough illegal characters it cause Server.MapPath to error.

Note: URLEncoding doesn't work because we are not cleaning a parameter, but the primary URL.

Check If Value Of Textbox Extended With MaskedEditExtender Is Valid?

May 19, 2010

Below is my code:

<asp:TextBox
ID="FromDateTextBox"
runat="server" />
<asp:ImageButton
ID="FromDateImageButton"
runat="server"
ImageUrl="~/images/calander.png" />
<ajaxkit:CalendarExtender
ID="FromDate"
runat="server"
TargetControlID="FromDateTextBox"
CssClass="CalanderControl"
PopupButtonID="FromDateImageButton"
Enabled="True" />
<ajaxkit:MaskedEditExtender
id="FromDateMaskedEditExtender"
runat="server"
targetcontrolid="FromDateTextBox"
Mask="99/99/9999"
messagevalidatortip="true"
onfocuscssclass="MaskedEditFocus"
oninvalidcssclass="MaskedEditError"
masktype="Date"
displaymoney="Left"
acceptnegative="Left"..........

I've set Culture="auto" UICulture="auto" in @Page directive and EnableScriptGlobalization="true" EnableScriptLocalization="true" in script manager to have client culture specific date format in my textbox.

I also have a Go button on my page on which I will do a partial post back. So, I want to validate the FromDateTextBox in javascript when the Go button is clicked.

UPDATE

I know how to create a javascript click handler. But because masked editor is already validating the date on focus shift, I'm thinking there should be some boolean property (like IsValid) exposed by it which will allow me to see if the text box contains valid date.

FURTHER TRIALS

I also tried below code and Page_Validators[f].isvalid always returns true even when the date is invalid and MaskEditValidator shows me a red star near the Text box.

function isDateValid() {
var b = true;
for (var f = 0; f < Page_Validators.length; f++) {
if (!Page_Validators[f].isvalid)
b = false;
}
return b;
}
$('#GoButton').click(function() {
if (!isDateValid()) {
return false;
}
loadProducts();
});

MVC :: Check Form Input Is Valid On Submit?

Jan 13, 2010

I have a form that when submitted shows a busy animation and disables the submit button.

Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.

At present my client side javascript looks like this:

Asp - JQuery - Check All Checkboxes

Jan 18, 2010

<asp:CheckBoxList> in a master page. the goal is to have all checkboxes in this list to be checked on page load. there are many checkbox lists on the page. The markup:

<asp:CheckBoxList runat="server" ID="chkSubscriptionType"
DataSourceID="myDS"
CssClass="boxes" DataTextField="Name" DataValueField="Name" />

renders to:

<input id="ctl00_cphContent_chkSubscriptionType_0" type="checkbox" name="ctl00$cphContent$chkSubscriptionType$0" />

how can you use jQuery to check all boxes in this asp:CheckBoxList on document.ready? I see samples everywhere, but naming convention used by the master page throws off the samples in other places.

JQuery :: Check Values In Html Page?

Mar 18, 2011

I have written a ajax function that I will check the result of a div tag to see if I want to hide the partial view and show the result. The result depends on what is coming back from the controller and the html(result variable). It should only go to the else statement if the return html string does not contain a div tag with id "valRegno". I do not know how I can find the div tag and check if it is there or not. The "result" htmls are nice and show me the details I am intrested but I can not extract it from the html string.
