  • submit remote form with prototype

    - by badnaam
    I have a remote form like this and a checkbox in it. When I select or deselect the checkbox I would like to 1 - set the value of a hidden field 2 - ajax submit this form to its designated url. I tried $('search_form').onsubmit(), but I get an error saying onsubmit is not a function. Using prototype. Whats the best way to do this? <form onsubmit="new Ajax.Request('/searches/search_set?stype=1', {asynchronous:true, evalScripts:true, parameters:Form.serialize(this)}); return false;" method="post" id="new_search" class="new_search" action="/searches/search_set?stype=1"><div style="margin: 0pt; padding: 0pt; display: inline;"><input type="hidden" value="3TWSyMsZXI0nltz7zHAxuj1KX=" name="authenticity_token"></div> <a onclick="setSubmit(this);" href="#" class="submit-link-button fg-button ui-state-default fg-button-icon-left ui-corner-all" id="search_submit"><span class="ui-icon ui-icon-search"></span>'Search'</a> </div> <input type="checkbox" value="Energy" onclick="refreshResults(this);" name="search[conditions][article_tag][0]" id="search_conditions_article_tag_0">

  • D3.js transition callback on frame

    - by brenjt
    Does anyone know how I could accomplish a per frame callback for a transition with D3. Here is and example of what I am doing currently. link.transition() .duration(duration) .attr("d", diagonal) .each("end",function(e) { if(e.target.id == current) show_tooltip(e.target) }); This currently calls the anonymous function for each element at the end of the animation. I would like to call it for every frame.

  • Quicker searching in JScript using the Bash

    - by gentlesea
    I am using the following JScript code to search for a string inside a file: var myFile = aqFile.OpenTextFile(fileToSearchIn, aqFile.faRead, aqFile.ctANSI); while(!myFile.IsEndOfFile()) { s = myFile.ReadLine(); if (aqString.Find(s, searchString) != -1) Log.Checkpoint(searchString + " found.", s); } myFile.Close(); This is rather slow. I was thinking about using bash commands in order to speed up the search in file process: var WshShell = new ActiveXObject("WScript.Shell"); var oExec = WshShell.Exec("C:\\cygwin\\bin\\bash.exe -c 'cat \"" + folderName + "/" + fileName + "\"'"); while (!oExec.StdOut.AtEndOfStream) Log.Checkpoint(oExec.StdOut.ReadLine()); while (!oExec.StdErr.AtEndOfStream) Log.Error(oExec.StdErr.ReadLine()); Since every time bash.exe is started a new window opens the searching is not faster than before. Is there a possibility to have the bash run in the background using another switch?

  • C question: error: expected ')' before '*' token

    - by lhw
    ===EDIT I apologize for not putting the pcb struct into the code snippet. There is a struct called pcb defined in above the two structs I originally posted. Namely, typedef struct{ UINT32 proc; struct pcb *link; }pcb; Hi, I asked a question regarding structs in C a few minutes ago and got an answer blazing fast. But now I'm facing another problem, namely the error in the title of this question. I'm trying to implement a simple priority queue in C using arrays of queues. However, when I try to declare a function on pcb_pQ structure, I get the above error. I have the structs clearly defined in the heard file. In the header file: typedef struct{ pcb *head; pcb *tail; SINT32 size; } pcb_Q; typedef struct pcb_pQ { pcb_Q queues[5]; SINT32 size; } pcb_pQ; Function prototype in header file: /*priority queue operations*/ VOID pcb_pq_enqueue(pcb_pQ*, pcb*); Function impelmentation in .c file: VOID pcb_pq_enqueue(pcb_pQ* pcb_pQ, pcb* pcb) { pcb_Q* pcb_Q_p; int priority; priority = pcb->proc_priority; pcb_Q_p = &pcb_pQ->queues[priority]; pcb_enqueue(pcb_Q_p, pcb); } When I try to compile the above code, I get an "error: expected ')' before '*' token". This error is pointing to the function signature in the .c file, namely VOID pcb_pq_enqueue(pcb_pQ* pcb_pQ, pcb* pcb) { But I am not sure why I am getting this error, could someone give me a hand? Thanks a lot.

  • jQuery - Animation Causes Div Overlap IE7

    - by Norbert
    I have a hidden div (#contactArea) above another div. When I click the link, the #contactArea opens up. When I click it again, it closes back up. It all works nicely, except in IE7. The two divs are transparent, so they overlap. I have no idea why this happens, or why doesn't it happen on other browsers. It just about feels like IE7 is right on this one. Any way to fix this? $(document).ready(function(){ $("#contactArea").css('display', 'none'); $("a.contact").toggle(function() { $("#contactArea").animate({height: "show"}, 1500, "easeOutBounce"); }, function() { $("#contactArea").animate({height: "hide"}, 1500, "easeOutBounce"); }); });

  • Menu glitchy on top of slideshow

    - by gnomixa
    I have implemented the following set up (after being requested): slideshow of images changing, after the user mouse over, the menu would appear in the top right corner, it would disappear on mouse out. The problem is that the menu it glitchy in both IE6/7 and FF 3.5. I have tried Jquery hover, mouseenter, mouseleave, all with the same result. http://www.codecookery.com/test/index.html is it possible to make it not glitchy at all?

  • Cross browser div center alignment using CSS

    - by Misha Moroshko
    What is the easiest way to align a div whose position is relative horizontally and vertically using CSS ? The width and the height of the div is unknown, i.e. it should work for every div dimension and in all major browsers. I mean center alignment. I thought to make the horizontal alignment using: margin-left: auto; margin-right: auto; like I did here. Is this a good cross browser solution for horizontal alignment ? How could I do the vertical alignment ?

  • Apache tiles and body onload event. Known issue?

    - by Angus
    We're prototyping a new visual framework using Apache Tiles for markup templating. Often the document onload event (actually prototype's dom:loaded event) is getting fired before all DOM objects are actually loaded Is it possible that the tiles templates are loading in an asynchronous fashion and therefore doing an end run around the event handler? Has anyone else had this experience? Can anyone share a robust workaround? thanks in advance

  • OpenLayers: Raise event when map is zoomed or moved by user

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom, and fitting the current view port. This should be relatively easy to do using the GetResolution and CalculateBounds methods on the Map object. However, I don't know when to call these methods because I can't find a way to register a function to be called when the user pans the map (changing the view port) or zooms the map (changing the resolution and view port). How can I get a callback when the user pans or zooms the map?

  • When onblur occurs, how can I find out which element focus went *to*?

    - by Michiel Borkent
    Suppose I attach an onblur function to an html input box like this: <input id="myInput" onblur="function() { ... }"></input> Is there a way to get the ID of the element which caused the onblur event to fire (the element which was clicked) inside the function? How? For example, suppose I have a span like this: <span id="mySpan">Hello World</span> If I click the span right after the input element has focus, the input element will lose its focus. How does the function know that it was mySpan that was clicked? PS: If the onclick event of the span would occur before the onblur event of the input element my problem would be solved, because I could set some status value indicating a specific element had been clicked. PPS: The background of this problem is that I want to trigger an Ajax.AutoCompleter control externally (from a clickable element) to show its suggestions, without the suggestions disappearing immediately because of the onblur event on the input element. So I want to check in the OnBlur function if one specific element has been clicked, and if so, ignore the blur event.

  • window.beforeunload called twice in Firefox - how to get around this?

    - by Zarkonnen
    I'm creating a popup window that has a beforeunload handler installed. When the "Close" file menu item is used to close the popup, the beforeunload handler is called twice, resulting in two "Are you sure you want to close this window?" messages appearing. This is a bug with Firefox, and I've reported it here, but I still would like a way to prevent this from happening. Can you think of a sane way of detecting double beforeunload to prevent the double message problem? The problem is that Firefox doesn't tell me which button in the dialog the user elected to click - OK or cancel.

  • In XMLHttpRequest, where is error flag variable?

    - by Tiangolo
    In the XMLHttpRequest Spec it says that: The DONE state has an associated error flag that indicates some type of network error or abortion. It can be either true or false and has an initial value of false. Also says something similar about a "send() flag" in an "OPENED" state. It's said in the specification but not in the IDL and when I create a new XMLHttpRequest I can't find those "flags". Where are those boolean variables?

  • ASCIIMath and TiddlyWiki

    - by Space_C0wb0y
    I use TiddlyWiki for work-notes. I already have pretty large wiki, but now I want to add math-support. As far as I understand what is written here, all I would have to do to use ASCIIMathML in my wiki would be including the script ASCIIMathML.js. Doesn't work (no effect at all). Then I found this plugin for TiddlyWiki, but when I import it to my wiki, it gives me an error in one of the regexp strings. When I download that wiki directly, ASCIIMath does not work anymore, even though I have the script in the same directory. Does anyone have a solution available, how I can add ASCIIMath to my existing TiddlyWiki?

  • How to not allow parts of sortable jquery list to move?

    - by sanpell
    I made a sortable list: <ul> <li class="line"><a href="#" class="food">milk</a></li> <li class="line"><a href="#" class="food">eggs</a></li> <li class="line"><a href="#" class="food">cheese</a></li> </ul> However, I want to make everything with class food not draggable. Since they are links, sometimes when people click them, they accidently reorder the list. Does anyone know how to make just the "food" class items not "draggable"?

  • Find window previously opened by window.open

    - by spender
    We've got the following situation, running from a single domain: Page A uses window.open() to open a named window (a popup player). window.open() gives page A a reference to the window. User now reloads page A. The reference to the named window is lost. Using window.open() to "find" the window has the unfortunate side effect of reloading it (undesirable). Is there any other way to get a reference to this window?

  • remove text in parentheses and the parentheses using .filter() or .slice()

    - by liz
    i have a table with code like this: <tr> <th scope="row">5-17</th> <td>23.6 (22.0-24.0)</td> <td>18.0 (17-20.0)</td> </tr> <tr> <th scope="row">Total 0-17</th> <td>20.6 (8-15.6)</td> <td>16.1 (22.2-24.0)</td> </tr> i am using the following function to find the contents of the table cells and bring it into an array: var l1 = $('#datatable td:nth-child(2)').map(function() { return $(this).text(); }).get(); the table fragment's id is "datatable". this returns properly, however i am putting this array into jqPlot and it cant read the stuff between the parentheses or the parentheses themselves. i need the data to remain in the table however because we are displaying both the table and the chart. i cant reformat (add spans around the content i want to remove etc) because these tables are being generated by another piece of software. i think what i need to do is either slice off after the space or use a regex to find and remove. not sure how to proceed with either of these. thanks!
