Web Forms :: Checking For Null Value In Window.location.pathname
Feb 16, 2011
I use the following code to get the file name out of the URL.
[Code]....
This works fine if there is actually a page that shows up after a '/', I would also like to check for when there is nothing showingup after the '/'. My alert above shows nothing to be there, but how do I chack for the nothing. I have tried the folloiwng, but for some resaon it just ignores me. If I do an if statement, it doesn't pick up that there isn't anything there.
if (sPage = '') { alert(sPage);}
Even though there isn't anything there, it won't show the alert and acts as if there is actually something there.
Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing if txtBox1.text.toString isNot nothing if txtBox1.text <> "" if txtBox1.text.toString <> "" if isNull(txtBox1) Is there on test that can cover them all?
I have a page that creates a pdf and opens the pdf. I use response.write with javascript using window.open to make the window open with the pdf, works fine. I then want the main window to do a redirect to a message page. But soon as I add code to do that (either more javascript using location.href or response.redirect, it does that but the window.open no longer works. It's like it's running the redirect before it really has a chance to finish the window.open. Is there a better way (a way that works LOL) to accomplish this?
I created a search functionallity for a client site but cannot get this Enter key search to navigate to my search box. I added HTML client controls as to server controls:
[Code]....
My Javascript does fire on enter key, and it does call the "searchProducts" method but not navigating to my desired location. Here is the Javascript: function searchKeyPress(e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { $('#go').click(); return false; } else { return true; } } function searchProducts() { var searchVal = $('#s').val(); var concLoc = [URL] window.location.href = concLoc; }
protected void rptNavigation_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e){ if (!((e.Item.ItemType == ListItemType.AlternatingItem) || (e.Item.ItemType == ListItemType.Item))) {return; }string Name = string.Empty; if (IsDBNull(e.Item.DataItem["FullName"])) { Name = String.Empty;} else {Name = (string)(e.Item.DataItem["FullName"]);} Literal ltlLiteral = (Literal)(e.Item.FindControl("ltlLiteral")); ltlLiteral.Text = Name.ToString();
I get error for IsDbNull - Error 1 The name 'IsDBNull' does not exist in the current context. What's the best way to check for null values returned from db? also I get errors on both lines where (e.Item.FindControl(ltlLiteral")); is present ERror: Cannot apply indexing with [] to an expression of type 'object'
I am making a class with an optional paramiter which will be a List<> paramiter. I want to set it's default value to null so I have used List<Params> Param = null. What am not 100% sure is checking the list to see if it was set to null or not. Is using:
.NET noob here (as in I know next to nothing, I'm trying to pick up some of the scraps left by my developer). Ok, I am getting this error on a number of my .aspx pages: Error while checking url '/': Key cannot be null. Parameter name: key Interestingly, I get this on my homepage on which the only .NET code is in the form of two includes, e.g: <% Response.WriteFile("/includes/footer.aspx") %> These includes in themselves only contain HTML, so I assume the issue can only be related to these or a configuration issue?
I have a FormView that is loaded with a records from my DB. Some of the fields may be blank or null. I am trying to check the value of some of the text boxes to verify that the user has updated the fields prior to allowing a DB update from the Edit Template.
I can not seem to get the correct syntax on the if statment to check the value of the text box....
Then I realized I don't know why I'm keeping the javascript call around at all. I'm just a little confused as to why it would have been written like that in the first place when a regular link would have worked just fine. What benefit does window.location have over just a regular link?
This is also the only place in the website I've seen something like this done (so far).
Edit: The programmer before me was highly competent, which is actually why I was wondering if there was something I wasn't taking into account or if he just made a simple oversight.
I've got a click tracking AJAX function (calls a WebMethod on an .aspx page), and I need to call it when the user clicks through to a link.Unfortunately, I'm using window.location = "newUrl" to change the page, which seems to make the AJAX call fail. Is there a way around this?I do not need to get any information back from the AJAX call, I just need to make sure the WebMethod is called'm aware that I could just redirect on the success() or failure() calls, but then I would have to wait for the clickTracking() method to run, which takes ~ 1s. That is not acceptable by the agreement in the project spec, and so is not a viable solution.
I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox. Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code:
function submitSearchOnEnter(e) { var CodeForEnter = 13; var codeEnteredByUser;
I have a web page that opens another web page in a pop up window. I would like to refresh the parent page when the submit button is clicked on the pop up page. I tried using window.opener.location.reload(); in IE7 but nothing seems to be happening.
I'm having one problem in mobile website using jquery.
i have written a code on button click to redirect using window.location='test.aspx' it doesn't work event my javascript validation is also not worked. how to explain if your in other country give error 406 forbidden access is deny.
I'm using Crystal Reports here. In the development stage (not published), my application works perfectly. After publishing, my application also works perfectly but whenever the crystal report involves images (picture of an employee, for example), this error pops-up.

Access to the path <pathname> is denied.

I have a table in my database, in which a certain field holds the locations of text or doc files (the files are of a transcript for a chat session).
In the Gridview right now i able to show the link locations. But i want to have Hyperlink or Button in the links location in the Transcript Location fields.And on the click of which the txt or doc file opens up in notepad or microsoft word.
function validateComment(source, args) { var reComment = new RegExp("^[a-zA-Z0-9',!;?@#%*.s]{1,1000}$"); var validComment = reComment.test(window.event.srcElement.value); if (!validComment) alert("The comment has illegal characters"); args.IsValid = validComment; }
Upon clicking the button that triggers the validator, the application breaks and I can see that the window.event property is null, so obviously there's a null reference trying to match the regEx. My question is why could the window.event be showing up as null? I could've sworn this was working before.
EDIT:
I have modified the function as such:
var check = document.getElementById(source.id); var checky = check.attributes["controltovalidate"].value; var checkyo = document.getElementById(checky); var validHour = reOutHour.test(checkyo.value); if (!validHour) alert("The time is incorrectly formatted"); args.IsValid = validHour;
Now this is working on Internet Explorer, but not on Firefox...
I have a Page that conatains a panel and an animation extender attached to it, when a button is clicked the panel appears but it gives me the above error in the title.. I know there's something wrong with the animation extender but really i don't have any idea from where to start
I'm storing a token in a session variable. I launch a report that needs this token in a new ASPX page by using the javascript windows.open function. When this new page loads the HttpContext.Current.Session is null.I have gotten around this by passing the token in the query string but activity in this window needs to keep the session of the parent window active and I'm not sure what the session object being null means for this scenario.
