ASP.NET: How to "reset" validation after calling Page_ClientValidate

- by Josh Young

I have an ASP.NET page with a jQuery dialog that is displayed to change some data. I am setting up the jQuery dialog so that when the user clicks the OK button it calls ASP.NET's Page_ClientValidate('validationGroup') via javascript, finds all the invalid controls and changes their CSS class. So here's the scenario: the user opens the dialog, keys in some invalid data, clicks OK (receiving the validation messages), and then clicks Cancel. Now the dialog is closed, but the validation messages are still there, so that when they open the dialog again, the data goes back to the way it was initially, but the form is still in the invalid state (the validation messages are still displaying). What I need is a "reset" function of sorts to call after calling Page_ClientValidate('validationGroup'). Does this exist?

How to Get the Method/Function Call Trace for a Specific Run?

- by JackWM

Given a Java or JavaScript program, after its execution, print out a sequence of calls. The calls are in invocation order. E.g. main() { A(); } A() { B(); C(); } Then the call trace should be: main -> A() -> B() -> C() Is there any tool that can profile and output this kind of information? It seems this is common a need for debugging or performance tuning. I noticed that some profilers can do this, but I prefer a simpler/easy-to-use one. Thanks!

document.forms.gallery_form.submit is not a function

- by Keene Maverick

I swear, I have this exact thing working on another page. I'm such a javascript noob it's embarrassing... function delete_gallery() { var gallery = document.getElementById('gallery_id').value; var form = document.getElementById('gallery_form'); form.setAttribute('action', 'index.php?action=delete&section=galleries&id='+gallery); document.forms['gallery_form'].submit(); } Inspecting the element shows that it's updating the action correctly : <form method="post" action="index.php?action=delete&section=galleries&id=12" name="gallery_form" id="gallery_form"><input type="hidden" value="12" id="gallery_id" name="gallery_id"><p>Name: <input type="text" name="name" value="Woo"></p><p>Description:<br><textarea name="description">Dee</textarea><input type="hidden" value="2" name="artist"></p><p><input type="submit" value="Submit" name="submit"> </p></form> Here's the button I use to call the function, it's in a table below the form: <button onclick="delete_gallery()" type="button">Delete Gallery</button>

ctrl-c does not copy text on a webpage

- by aepheus

I've come across this several times, ctrl-c randomly does not copy. I think it's caused by javascript or maybe some odd html syntax. I never spent the time to track down what caused it. Anyone know the typical/common causes of ctrl-c not working (to copy) on a website? Speaking from a developers standpoint. What do we developers end up doing to break ctrl-c? Just to clarify, I'm not interested in preventing copying. I'm trying to do the opposite, occasionally I find I've done something that is preventing ctrl-c from copying text, and that is not very user friendly on a text heavy site.

How to calculate textarea cols with 100% width?

- by sehwoo

I set the width of a textarea to 100%, but now I need to know how many characters can fit in one row. I'm trying to write a javascript function to auto-grow/shrink a textarea. I'm trying to keep from using jquery since I just need this one function. My logic is to rows = textarea.value.split('\n'), iterate through rows and count += rows[i].length/textarea.cols, then count += rows.length, and finally textarea.rows = count. The only problem is that count is too large because textarea.cols is too small.

How to set cell's background in HTML table ?

- by misha-moroshko

I would like to set the background of a cell in HTML table to be like this. What are my options besides using an image as background ? Are there any predefined backgrounds like this ? Maybe dotted, or diagonal lines backgrounds ? In case of image background, if I don't know in advance what would be the size of the cell, what image size should I take ? How to make it be repetitive so it would look nice ? Any HTML/CSS/Javascript/jQuery suggestions are welcome :)

Specific position for tooltip

- by Fiona

Hello, I have a layer which opens up as a tooltip everytime I hover a button. I simply did that by creating a JS function which displays or hides the layer. Now, I am not a pro in JavaScript. My problem is the following: when the button is scrolled towards the top oft he screen I want the tooltip opening below – and if the button is near the bottom of the screen I want the tooltip opening above. Right now I just did it with absolute positioning. But obviously that doesnt do the trick. Who can help? Thanks!

Ideas on limiting content to single printed page?

- by James Skidmore

I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

How to stop a Timer-X timer (jQuery)

- by Damien K.

I'm using Timer-X's timerDelayCall function in order to have a repeating rotator on my page, which starts automatically as the page loads: jQuery.timerDelayCall({ interval: 2000, repeat: true, callback: function(timer) { ... (my rotator logic here) } } }); The problem is that I'm trying to make a function that includes stopping that timer: function signUp() { ... (timer stop code here) } The documentation stats that timer.stop() does that, but however I format it, I get errors about it not being declared. I have tried every variation I can think of, such as: timer.stop(); jQuery.timer.stop(); $(document).timer.stop(); jQuery.timerDelayCall({ callback: function(timer) { timer.stop() } }); I'm sure I'm missing something simple - I come from a PHP background yet I'm new to javascript - but can't see what it is exactly. Help is much appreciated!

- by Cristian Boariu

Hi, I load a js variable like this: var message = '<%= CAnunturi.CPLATA_RAMBURS_INFO %>'; where the static string CPLATA_RAMBURS_INFO i put like: public static string CPLATA_RAMBURS_INFO = "test"; I use it very well in this method. <script type="text/javascript"> var categoryParam = '<%= CQueryStringParameters.CATEGORY %>'; var subcategoryParam = '<%= CQueryStringParameters.SUBCATEGORY1_ID %>'; var message = '<%= CAnunturi.CPLATA_RAMBURS_INFO %>'; function timedInfo(header) { $.jGrowl(message, { header: header }); }; </script> so the message appears. I do not undersand, why, iso of "test", if i take the value from a static method, ths use of message js var is no longer succesfull (the message no longer appears). public static string CPLATA_RAMBURS_INFO = getRambursInfo(); public static string getRambursInfo() { return System.IO.File.ReadAllText(PathsUtil.getRambursPlataFilePath()); } Any help would be highly appreciated....

Generate custom marker (icon) out of two images in Leaflet

- by Rmatt

In Javascript/CoffeeScript, using Leaflet to display a map, I would like to have custom markers out of a two custom images, and also featuring a shadow for the pin : I want to have a "background" image with a color (or shape) to identify the category On top, I want to have inside this image a specific image (logo) for each pin I didn't find out how I could do that... Setting one image is quite easy but I don't know how to overlay them. I could also consider using a tool to superpose/group/overlay these images (locally ?) before in order to send only one to the Icon Leaflet Class, but also there, I wouldn't know which tool to use. Nevertheless, I still think that a double overlay would be more efficient and that my case could be useful for several people.

using ajax url to call function

- by Steven Vanerp

Hopefully I can ask this correctly cuz I know what I want it to do but can't seem to find any answers from searching. I have a func.php page where I have all my functions and I want ajax to use one function from that page. func.php function toptable() { echo"something happens in here"; } index.php <?php include 'func.php'; ?> <script type="text/javascript"> function check_username() { uname=document.getElementById("username").value; var params = "user_id="+uname; var url = "topoftable()"; $.ajax({ type: 'POST', url: url, dataType: 'html', data: params, beforeSend: function() { document.getElementById("right").innerHTML= 'checking' ; }, complete: function() { }, success: function(html) { document.getElementById("right").innerHTML= html ; } }); } </script> Make sense?

any ideas for avoiding duplicate code in C# and javascript

- by ooo

i have an asp.net mvc website where i build up most of the page using C# for example building up html tables given a set of data from my viewmodel i also have a lot of javascript that then dynamcially modifies these tables (add row for example). the javascript code to add a new row looks extremely similar to my "rendering" code i have in C# that is used to build up the html table in the first place. Every time i change the c# code to a add a new field, i have to remember to go back to the javascript code to do the same. is there a better way here?

How to customize the to_json method in rails3?

- by lashleigh

I want to convert an array of Place objects to json, I've been doing it like this: var places = <%= @places.to_json.html_safe %>; The only problem is that every place in the @places array has an associated tag list that doesn't get included. I'm using the acts_as_taggable_on gem to handle tags, so to get the tag list for a place I need to say place.tag_list. What do I have to do to get the tag_list included for each place in the javascript array? I think I'll need to write my own to_json method but I don't know how. Thanks

jQuery sanitizing comments and linkifying URLs

- by iWasRobbed

In terms of jQuery (or Javascript), what happens behind the scenes when a person posts a comment on Facebook, Twitter, or a blog? For instance, do they sanitize the text first, and then pattern match URL's into an actual link? Are there other items of concern that the client-side should check in addition to doing some checks on the backend? I have found a few regex's for turning URL's into links, but I'm not sure if there are better solutions. I'm trying to wrap my head around the problem, but I'm having a difficult time knowing where to start. Any guidance you can provide is greatly appreciated!

Preloading images in HTML, is there a more modern way?

- by John

I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?

How to check if people liked my Facebook FanPage

- by user2372419

There are many questions and answers about this. But nowadays Facebook changes their Privacy. Any Application that request for user_likes permission must be review by Facebook before using. I've tried many times to explain to Facebook review team about my app, but they did not accept, because my application (a web game using HTML5 and JavaScript) require people like my fan page before play. So my question is: Is there any to bypass Facebook privacy? I have a Like Box on the same page as the game screen (where i need to check Like), so any solution (like: analyze DOM elements, capture screen can pass through image recognition) will fine.

.net MVC, dealing with json and Areas

- by JoseMarmolejos

When not using areas dealing with the url for the JsonResults from the clientside is not much of a pain, usually you can get away with hardcoding the url into your json calls and get away with it. Problem arises when you have different areas and you don't want to update all your links when you move a controller (and its views) from one area to the other. I'm not very satisfied with the way I'm handling this scenario by having this chunk of code inside every view: <script type="text/javascript"> var ControllerActions = { JsonSearch: '<%= Url.Action("JsonSearch") %>/', JsonDelete: '<%= Url.Action("JsonDelete") %>/', Edit: '<%= Url.Action("Edit") %>/', Delete: '<%= Url.Action("Delete") %>/' } </script> While it does work no matter where I place the views/controllers I wonder if there's a more elegant to do this.

Image Replacement (JS/JQuery) working in IE but not FF

- by Sunburnt Ginger

I have tried multiple solutions for replacing broken images (both JS & jQuery) and all work perfectly with IE but not in FF, is there a reason for this? Are images handled differently in FF that may cause this? JQuery Example: $("img").error(function(){ $(this).unbind("error").attr("src", "nopic.jpg"); }); Javascript Example: (triggered by onError event in img tag) function noimage(img){ img.onerror=""; img.src="nopic.jpg"; return true; } Both of these examples work perfectly in IE but not at all in FF. What gives? Thanks in advance!
