Ajax :: Safari Bug - Checked Radio Not Checked ?
stackoverflow.com
In Safari, If I load a piece of html via XHR (ajax) the browser does not render the radio button that has the checked="checked" attribute as checked. The html I fetch via ajax: CODE: The browser renders two unchecked radio buttons. If I load the exact same code directly from a plain html file (no ajax) the radio buttons render as they should, the last being in its checked state. What's wrong, is this a known bug? Is there a fix available? EDIT: Probing further this looks like a browser bug, and I could not so far fix it with jQuery Post processing.. here is what I've found: I have a page that pulls in some form element via ajax. The html is this: CODE: After the form element are pulled in, the checkboxed render correct, but the radios both render unckecked. Now, If i run the following jQuery command (from the Safari 5 console): CODE: It returns an object containing the one checked checkbox. But if I run the command: CODE: It actually retuns the correct object, and it even shows its outerHTML property correct like this: CODE: Now, if I do: CODE: Safari get's it, and renders it correctly. I guess I'll just have to pass a data-ischecked="true" attribute and use that to catch and 're-check' all radio buttons after the ajax bit is loaded.. but still, even if I can do this.

Web Forms :: CheckBox Checked="False" Interpreted As Checked="True"?
forums.asp.net
I'm adding a checkbox to my Web Form in the CodeBehind class and setting its Checked property to False.  I've verified the value as I'm debugging my code. [code].... When the checkbox is written out to the browser, it's written as: <input type="checkbox" checked="False" id="fndt_WaiverTransferCharge" /> Apparently the checked="False" attribute confuses the browser and I end up with a checked checkbox.  On PostBack when I test the value of the checkbox, it's False (unless I change it) so it's got to be a browser presentation issue.  I know that when you write a checkbox in straight HTML, the checked attribute doesn't require a value, i.e.: <input type="checkbox" checked /> Is there a way to fix this?

Check If File Is Finished Copying?
stackoverflow.com
I'm writing an ASP.NET webapp that will copy the contents of a CD to a network share. I need to check periodically if the copy job is finished. One way of doing this is checking the network share folder to see if the file size has changed since the last check, but that seems kind of dodgy. Does anyone have a better idea how to do this? EDIT some more explanation: Basically I'm calling a JsonResult action method every 5 seconds, called getStatus(source,destination). This method needs to check the following: - if the source dir is still empty, copy cannot start --> return status "waiting" - if the source dir contains files, copy can start -_> call copy method + return status "copying" - if the destination dir contains files, and file size stays the same, copy is finished --> return status "finished"

MVC Validator To Make Sure At Least One Checkbox Is Checked
stackoverflow.com
I have an ASP.NET MVC 2 project in which I've created a data transfer object to receive data from a web page form. The form has two groups of checkboxes on it. I want to validate the object to make sure that at least one of the checkboxes in each group is checked. I'm doing the validation on the server side so that a user won't be able to hack around any client-side validation. (I will add client-side validation with jQuery later; that's easy.) My understanding is that I have to create my own custom ValidationAttribute for my data transfer object class, but I don't understand how to create and use one that can accept an arbitrary list of checkbox properties to make sure that at least one of them is true. I am guessing I will have to call the attributes like this: [AtLeastOneCheckbox("set1check1", "set1check2", "set1check3", ErrorMessage = "You must check at least one checkbox in set 1.")] [AtLeastOneCheckbox("set2check1", "set2check2", "set2check3", "set2check4", "set2check5", ErrorMessage = "You must check at least one checkbox in set 2.")] public class MyFormDTO { ... } What would the implementation of AtLeastOneCheckboxAttribute look like? Or is there a different way that I should do this kind of validation?

VS 2008 Spell Checking In VS2008?
www.vbforums.com
I am using the C1 enterprise control set that has a web editor with spell checking. But I have to click a button to check the spelling. Does anyone use an editor that checks the spelling as you type and highlights the words rather than using a dialog box at the end? I think some controls use a javascript and calls the spell checker at intervals so the words are highlighted while you type.Does anyone know if a control like this that is not expensive?

Check If Custom Exception Handler Has Been Set?
stackoverflow.com
I want to call set_exception_handler() only if no other exception handler has been register before, hence the default handler is in use. I need that, because I want to log exceptions to file in production code, but I don't want to register exception handler when PHPUnit is running my code, because it need to catch all errors.

Check If Server Is Up
www.phpbuilder.com
In basic what I need is, if my custom 500 error page is called I need to check if the server is actually down. On occasion we are seeing the site gets maxed out on the number of processes that can run simultaneously (the shared host allows a max of 25 processes). The problem is email, every time someone checks their email it starts 2 processes, but it seems some email clients like to open up several processes (I've seen up to 10 for one email account) and then if a few more people are checking email and then some are using the web app and then if we get a spurt of visitors, the site maxes out on the number of processes running and all the sites go down. So to fix this we have an email sent to 3 people when anyone lands on the custom 500 error page so we can manually terminate the email processes. The problem we are dealing with is rogue bots, we are now getting between 10 to 20 emails a day and all are just rouge bots. I can keep legitimate bots from landing on the page, or indexing it, using robots.txt but rogue and malicious bots use the robots.txt to find hidden files they can potentially exploit. So I am wanting to add, to the custom 500 page, a way to check if the server is actually down. I was thinking of just using fsockopen to send a request to my personal site (on a different server) and then having a script there that will use fsockopen to call a file from the first server. And if any request fails an email is then sent to the 3 of us. But I thought possibly php may have some function that is specifically for this purpose and I just have not found it yet. Or, if not, there may be a standardized method of doing this other than fsockopen or even cURL. So what is the correct way to go about checking if the server is no longer serving up pages to visitors?

Allowing User Check / Uncheck All Checkboxes In Form
www.codingforums.com
I am trying to allow a user to easily uncheck/check all checkboxes in a form by checking or unchecking a checkbox. The checkboxes would be in a form like so: <form action="" method="post"> <input type="checkbox" name="checked[]" value="1"> <input type="checkbox" name="checked[]" value="2"> <input type="checkbox" name="checked[]" value="3"> <input type="checkbox" name="checked[]" value="4"> </form> I use an event handler to call a function: <input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)"> And here is the function: function checkall(box_name, current_state) { all = document.getElementsByName(box_name); action = (current_state == "checked") ? "false" : "true"; for (i = 0; i < all.length; i++) { all[i].checked=action; }} The event handler should pass the name of the checkboxes and whether the "check all" checkbox is currently checked or not to the checkall() function. Nothing happens when I check/uncheck the "check all" function.

JQuery :: How To Check If Two Elements / DIV Belong To Same Parent

Checking The 'message' Parameter Of The Mail Function
bytes.com
I would imagine it is a fairly common situation for a site to allow the user to enter some text into a field and then to have that text passed to the 'message' parameter of the mail function (http://us4.php.net/manual/en/function.mail.php). Is it a good idea to pass this text through some other function first or can it be sent through as is? Is this a case where the maxim 'do not trust input from the user' does not apply?

Check That A Product Is Still In The Warranty Period
www.webmasterworld.com
What i want to do is to check that a product is still in the warranty period. Warrant period is 1 year. So i get the shipdate from the data base and enter the ruturned date. $SHIPDATE = &#55614;&#57158;-05-10' $RETURNDATE = &#55614;&#57159;-02-28' $INWAR = ($SHIPDATE - $RETURNDATE); ECHO "$INWAR"; What is returned is -1. I think it is only using the year out of the date and not all of it. Do i have to convert the date into another format.

Checking Conditions In Multidimensional Array?
stackoverflow.com
I have an array like this: $_SESSION['food'] = array( array( "name" => "apple", "shape" => "round", [code].... I want to make a statement that checks whether any particular combination of values exists within any of the second level arrays above. if NAME=APPLE and COLOR=RED in FOOD // returns true if NAME=BANANA and COLOR=GREEN in FOOD // returns false if NAME=APPLE and SHAPE=LONG in FOOD // returns false How would I construct the if() statements above (just one statement as an example would be sufficient)? I am really stumped here. I suspect it has something to do with running an in_array() within a foreach(), but I am not sure of the exact syntax.

Ticking A Check Box Based On A Value From A Record

Trouble is I want the check box to be ticked if the value is 1 and unticked if the value is 0 I thought of using a function such as function checked($avail) { if ($avail = $available) { return 'checked' } } after the value part of the code (where I have written MYFUNCTIONHERE) which would put the work 'checked' in the appropriate place but my inexperience means I cant get the syntax correct

Making Sure A Radio Button Is Checked
www.sitepoint.com
I need to know how to use Javascript to test if any one of a series of radio buttons has been checked. There's a catch, though: The radio buttons and their values are dynamically generated out of a database, so there's no way of knowing ahead of time how many radio buttons there will be or what the value associated with each button will be. Thus, I can't simply test the value of each button separately, nor can I use an array unless I can figure out how to count how many options there are when the page is dynamically generated. It seems like there should be any easy way!

JQuery :: Find Out If Radio Button Is Checked?

I can set a radio button to checked fine, but what I want to do is setup a sort of 'listener' that activates when a certain radio button is checked. Take, for example the following code: $("#element").click(function() { $('#radio_button').attr("checked", "checked"); }); it adds a checked attribute and all is well, but how would I go about adding an alert. For example, that pops up when the radio button is checked.

Checking HTML5 Drag And Drop File Type

I'd like to change drop zone background color to green or red depending on whether the contained drag over payload contains supported file types (JPEG). Do Gecko and Webkit support determining the file type of drag and drop files? How one can extract the file type in these two browsers? I have found event.dataTransfer.types API, but for Firefox it seems to be populated with application/x-moz-file and thus I think I am doing something wrong.
