  • I need to add a range for a date input field in jquery

    - by user338413
    I've got an input field in a form that needs a date value. I'm using jQuery UI's datepicker for the calendar and I've set a range for it. However, the user can override that by typing a different date in the input field. How can I specify a date range for the field with jQuery validation? All I see with jQuery is that you can only specify that the field be a date type. Can I create min and max values that work with dates?

  • jQuery UI: how to run evaluation

    - by mikkelbreum
    I want to add 'Year' or Years' to the end of a string depending on the string. Like this: $("#selector").val(conditional_value_here); Using jQuery UI I have a slider that manipulates a value: $("#slider").slider({ value: 1, min: 1, max: 25, step: 1, slide: function(event, ui) { $("#amount").val(ui.value + ' Year' + function(){return (ui.value == 1) ? '' : 's';} ); } }); // and again I want to do the same for the initialization of the value: $("#amount_3").val($("#slider_3").slider("value") + ' Jahr' + function(){return ($("#slider_3").slider("value") == 1) ? '' : 's';}); This does not work. What is the correct way to to this?

  • C# Struct No Parameterless Constructor? See what I need to accomplish

    - by Changeling
    I am using a struct to pass to an unmanaged DLL as so - [StructLayout(LayoutKind.Sequential)] public struct valTable { public byte type; public byte map; public byte spare1; public byte spare2; public int par; public int min; public byte[] name; public valTable() { name = new byte[24]; } } The code above will not compile because VS 2005 will complain that "Structs cannot contain explicit parameterless constructors". In order to pass this struct to my DLL, I have to pass an array of struct's like so valTable[] val = new valTable[281]; What I would like to do is when I say new, the constructor is called and it creates an array of bytes like I am trying to demonstrate because the DLL is looking for that byte array of size 24 in each dimension. How can I accomplish this?

  • Converting time period strings to value/unit pair

    - by randomtoor
    I need to parse the contents of a string that represents a time period. The format of the string is value/unit, e.g.: 1s, 60min, 24h. I would separate the actual value (an int) and unit (a str) to separated variables. At the moment I do it like this: def validate_time(time): binsize = time.strip() unit = re.sub('[0-9]','',binsize) if unit not in ['s','m','min','h','l']: print "Error: unit {0} is not valid".format(unit) sys.exit(2) tmp = re.sub('[^0-9]','',binsize) try: value = int(tmp) except ValueError: print "Error: {0} is not valid".format(time) sys.exit(2) return value,unit However, it is not ideal as things like 1m0 are also (wrongly) validated (value=10,unit=m). What is the best way to validate/parse this input?

  • JavaScript - Is it possible to get height from div in separate page?

    - by Kenny Bones
    Hi, I'm wondering, is it possible to collect the height of a specific div container from a separate page with JavaScript? I'm using jQuery btw and I'm in need of comparing heights of div containers. Edit: To clarify a bit more, I load content from a specific div in a separate page using jQuery. This content is faded into a different container with dynamic height. But in the small fraction of time before the content arrives, it shrinks down to it's min-height. What I've done so far is collecting the height of the container before and after the load. But it only works after I've loaded content once. Because I don't have the height before it's been loaded the first time.

  • antlr: How to rewrite only specific

    - by user1293945
    I am sure antlr can solve my problem, but can't figure out how to implement it, even high level. I rapidly got caught into syntax problems of antlr itself. My grammar is quite simple and made of following tokens and rules. Don't really need to go in their details here. The evaluator resolves to expressions, which finally resolve to IDENT: evaluator : expression EOF! ; ... ... term : PARTICIPANT_TYPE(IDENT | '('! expression ')'! | max | min | if_ | NUMBER)+ ; Now, I would like to analyse and rewrite the 'term', so that IDENT tokens (and them only) get re-written with the PARTICIPANT_TYPE. All the others should simply remain the same.

  • For each element A[i] of array A, find the closest j such that A[j] > A[i]

    - by SamH
    Hi everyone. Given : An array A[1..n] of real numbers. Goal : An array D[1..n] such that D[i] = min{ distance(i,j) : A[j] > A[i] } or some default value (like 0) when there is no higher-valued element. I would really like to use Euclidean distance here. Example : A = [-1.35, 3.03, 0.73, -0.06, 0.71, -0.21, -0.12, 1.49, 1.41, 1.42] D = [1, 0, 1, 1, 2, 1, 1, 6, 1, 2] Is there any way to beat the obvious O(n^2) solution? The only progress I've made so far is that D[i] = 1 whenever A[i] is not a local maxima. I've been thinking a lot and have come up with NOTHING. I hope to eventually extend this to 2D (so A and D are matrices).

  • Expand <div> tag to bottom of page with CSS

    - by typoknig
    Hi all, I know this question gets asked a lot because I have looked at many "solutions" trying to get this to work for me. I can get it to work if I hack up the html but I want to use all CSS. All I want is a header with two columns below it, and I want these three items to fill the entire page/screen, and I want to do it with CSS and without frames or tables. The XAMPP user interface looks exactly how I want my page to look, but again, I do not want to use frames. I cannot get the two orangeish colored columns to extend to the bottom of the screen. I do have it so it looks like the right column extends to the bottom of the screen just by changing the body background color to the same color as the background color of the right column, but I would like both columns to extend to the bottom so I didn't have to do that. Here is what I have so far: HTML <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html dir="ltr" xmlns="http://www.w3.org/1999/xhtml"> <head> <title>MY SITE</title> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <link href="stylesheet.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="container"> <div id="masthead"> MY SITE</div> <div id="left_col"> Employee Management<br /> <a href="Employee%20Management.php">Add New Employee</a><br /> <a href="Employee%20Management.php">Edit Existing Employee</a><br /> <br/> Load Management<br /> <a href="Load%20Management.php">Log New Load</a><br /> <a href="Load%20Management.php">Edit Existing Load</a><br /> <br/> Report Management<br /> <a href="Report%20Management.php">Employee Report</a><br /> <a href="Report%20Management.php">Load Report</a></div> <div id="page_content"> <div id="page_content_heading">Welcome!</div> Lots of words</div> </div> </body> </html> CSS #masthead { background-color:#FFFFFF; font-family:Arial,Helvetica,sans-serif; font-size:xx-large; font-weight:bold; padding:30px; text-align:center; } #container { min-width: 600px; min-height: 100%; } #left_col { padding: 10px; background-color: #339933; float: left; font-family: Arial,Helvetica,sans-serif; font-size: large; font-weight: bold; width: 210px; } #page_content { background-color: #CCCCCC; margin-left: 230px; padding: 20px; } #page_content_heading { font-family:Arial,Helvetica,sans-serif; font-size:large; font-weight:bold; padding-bottom:10px; padding-top:10px; } a { color:#0000FF; font-family:Arial,Helvetica,sans-serif; font-size:medium; font-weight:normal; } a:hover { color:#FF0000; } html, body { height: 100%; padding: 0; margin: 0; background-color: #CCCCCC; }

  • How to make bottom half of a page take up remaining height?

    - by RobVious
    I've searched and tried a bunch of different things. I have a variable-height tophalf, and the bottom half should fill up the remaining space. A JSfiddle: http://jsfiddle.net/UCJmQ/ CSS: .top { background-color: lightblue; height: 300px; } .bottom { background-color: green; min-height: 100px; overflow: hidden; height: 100%; } html, body { height: 100%; } HTML: <div class="top"></div> <div class="bottom"> </div> What I'm seeing now is the green page taking up the entire window's height, not the remaining height. How can I make it take the remaining height instead?

  • Creating a textarea with auto-resize

    - by DisgruntledGoat
    There was another thread about this, which I've tried. But there is one problem: the textarea doesn't shrink if you delete the content. I can't find any way to shrink it to the correct size - the clientHeight value comes back as the full size of the textarea, not its contents. The code from that page is below. I'd appreciate any help or pointers. function FitToContent(id, maxHeight) { var text = id && id.style ? id : document.getElementById(id); if ( !text ) return; var adjustedHeight = text.clientHeight; if ( !maxHeight || maxHeight > adjustedHeight ) { adjustedHeight = Math.max(text.scrollHeight, adjustedHeight); if ( maxHeight ) adjustedHeight = Math.min(maxHeight, adjustedHeight); if ( adjustedHeight > text.clientHeight ) text.style.height = adjustedHeight + "px"; } } window.onload = function() { document.getElementById("ta").onkeyup = function() { FitToContent( this, 500 ) }; }

  • how to select distinct rows for a column

    - by Satoru.Logic
    Hi, all. I have a table x that's like the one bellow: id | name | observed_value | 1 | a | 100 | 2 | b | 200 | 3 | b | 300 | 4 | a | 150 | 5 | c | 300 | I want to make a query so that in the result set I have exactly one record for one name: (1, a, 100) (2, b, 200) (5, c, 300) If there are multiple records corresponding to a name, say 'a' in the table above, I just pick up one of them. In my current implementation, I make a query like this: select x.* from x , (select distinct name, min(observed_value) as minimum_val from x group by name) x1 where x.name = x1.name and x.observed_value = x1.observed_value; But I think there may be some better way around, please tell me if you know, thanks in advance.

  • How to use default.ctp in cakephp

    - by Louis Stephens
    I just finished the "15 min Blog Post tutorial" included in the documentation for cakephp. I was asked for another tutorial to change the layout for first tutorial. However, I am fairly new to MVC programming/Cakephp and I have no real clue how to do so. Well, I know I need "default.ctp" placed in app/views/layouts/ and I presume I need to include to include my data? . . . I am really at a loss of what to do. I set up my default.ctp as I mentioned above, but when I go to localhost:9999/posts the layout is still the same. I guess I need to include a stylesheet (and if so, where?) I guess if someone can point me in the right direction to a beginner's guide to layout styling or how to use it I would greatly appreciate any help.
