  • Next/Previous click jQuery UI

    - by madjester
    I am trying to add next/previous buttons on a button click using the jQuery UI Slider. I found this code... $("#down").click(function() { var s = $("#slider"), val = s.slider("value"), step = s.slider("option", "step"); s.slider("value", val - step); }); $("#up").click(function() { var s = $("#slider"), val = s.slider("value"), step = s.slider("option", "step"); s.slider("value", val + step); }); Here: http://osdir.com/ml/jquery-ui/2009-03/msg00617.html However this only changes the value of the Slider, moving the slider handle, but it doesn't actually slide the element. Little help?

  • jQuery .noconflict with prototype not working in (you guessed it) IE.

    - by Kyle Sevenoaks
    On my new customer page, I have successfully implemented a jQuery show/hide toggle alongside a Prototype script using jQuery's .noconflict. (Thanks to all for answers!) But as the world of the net is, IE's not playing ball. {literal} <script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"> </script> <script type="text/javascript"> var $j = jQuery.noConflict(); $j(function() { $j("#button1").click(function() { $j("#show-hide").toggle("slow"); }); });? </script> {/literal} As you all must know by now, I'm just newly coming to all this jQuery stuff, so I have no idea what could cause it. Thanks for any help.

  • jQuery ajax get

    - by Happy
    There are many class="item" blocks on the page. For each one there is different var item_link and ajax request. Ajax searches for src attribute of .message img and throws it to var src. $(".item").each(function(){ var item_link = "http://..."; $(this).prepend('<div class="src"></div>'); $.get(item_link, function(data) { var src = $('.message img', data).attr('src'); }); }); How to print var src to <div class="src"></div>? Thanks.

  • using jquery $.post() for returning multiple values

    - by Aninemity
    Hi all I am trying to use a $.post() in the following way: $.post("file.php", { file_id: $(this).val()}, function(data){...} The file.php then does a database query and returns an array with a title, description and image reference. What I want to do then is be able to update the .val() for form fields for each. I understand how to do this on a single variable, it would just be the following: $.post("file.php", { file_id: $(this).val()}, function(data){ $('#title').val(data); } But, how do I get the data returned to be recognizable in jquery as either separate variables or as an array? Thanks in advance

  • Unable to return/process JSON in JQuery $.get()

    - by shyam
    I have a problem returning/processing JSON data while calling $.get() function. Here's the code: JQuery: $.get("script.php?", function(data) { if (data.status) { alert('ok'); } else { alert(data.error); } },'json'); PHP if ($r) { $ret = array("status"=>true); } else { $ret = array("status"=>false,"error"=>$error); } echo json_encode( $ret ); So this is the code. But the response is always taken as string in the jquery. data.status and data.error is undefined.

  • jquery selector for td in a table

    - by ooo
    i want to get a event that will fire when i click inside a td of a html table i had this: ('td').live('click', function() { alert($(this).attr('id')); }); which works but this fires inside the 'th" cells as well (not sure why). is there any selector that just fires inside td's and not th's. I tried this: ('tbody td').live('click', function() { alert($(this).attr('id')); }); but that didn't seems to stop this firing for the th's.

  • "this" in JavaScript

    - by cf_PhillipSenn
    I'm trying to understand the syntax of how to put together a JavaScript function as an object. Q: Is this the right way to do it? The reason why I ask is because I'm looking at it in Firebug and I was hoping to be able to drill down and see the value of myVar and myVariable, but instead Firebug only says that "this" is an object Object. var myObject = { init: function() { var myVar = 1; myObject.myVariable = 2; console.log('"this" when called as an object: ' + this); } } myObject.init(); Also, what's the funny little syntax to call it directly upon declaration? Something about (), but when I remove the last line and put () at the end of the declaration, I get a syntax error.

  • why does it use the movl instead of push ?!

    - by user554403
    hi all. pay attention to this code : #include <stdio.h> void a(int a, int b, int c) { char buffer1[5]; char buffer2[10]; } int main() { a(1,2,3); } after that : gcc -S a.c that command shows our source code in assembly. now we can see in the main function, we never use "push" command to push the arguments of the a function into the stack. and it used "movel" instead of that main: pushl %ebp movl %esp, %ebp andl $-16, %esp subl $16, %esp movl $3, 8(%esp) movl $2, 4(%esp) movl $1, (%esp) call a leave why does it happen? what's difference between them?

  • Why do these seemingly similar queries have such drastically different run times?

    - by Jherico
    I'm working with an oracle DB trying to tune some queries and I'm having trouble understanding why working a particular clause in a particular way has such a drastic impact on the query performance. Here is a performant version of the query I'm doing select * from ( select a.*, rownum rn from ( select * from table_foo ) a where rownum < 3 ) where rn >= 2 The same query by replacing the last two lines with this ) a where rownum >=2 rownum < 3 ) performs horribly. Several orders of magnitude worse ) a where rownum between 2 and 3 ) also performs horribly. I don't understand the magic from the first query and how to apply it to further similar queries.

  • jQuery.post not working when using data type json

    - by swift
    I have been trying to utilize json in this jQuery.post because I need to return two values from my executed php. The code was working when I was not implementing json. I need to see if a promo code entered is valid for a particular broker. The two variables I need back are the instant message whether or not it's valid (this is displayed to the user) and I need to update a hidden field that will be used later while updating the database. The jQuery.post does not seem to be firing at all, but the code directly above it (the ajax-loader.gif) is working. I did re-write the whole thing at one point using jQuery.ajax, and had issues there too. Granted, I have probably been looking at this too long and have tried to re-write too many times, but any help is greatly appreciated!! Here's the jQuery.post <!-- Below Script is for Checking Promo Code Against Database--> <script type="text/javascript"> jQuery(document).ready(function() { jQuery("#promocode").keyup(function (e) { //removes spaces from PromoCode jQuery(this).val(jQuery(this).val().replace(/\s/g, '')); var promocode = jQuery(this).val(); var brokerdealerid = document.getElementById("BrokerDealerId").value; if(promocode.length > 0 ){ jQuery("#promo-result").html('<img src="../imgs/ajax-loader.gif" />'); jQuery.post( '../check_promocode.php', {promocode:promocode, brokerdealerid:brokerdealerid}, function(data) { $("#promo-result").html(data.promoresult); $("#promo-result-valid").html(data.promovalid); }, "json"); } }); }); </script> <!-- End Script is for Checking Promo Code Against Database--> Here's relevant code from check_promocode.php: //sanitize incoming parameters if (isset($_POST['brokerdealerid'])) $brokerdealerid = sanitizeMySQL($_POST['brokerdealerid']); $promocode = sanitizeMySQL($promocode); //check promocode in db $results = mysql_query("SELECT PromotionCodeIdentifier FROM PromotionCode WHERE PromotionCodeIdentifier='$promocode' AND BrokerDealerId='$brokerdealerid' AND PromotionCodStrtDte <= CURDATE() AND PromotionCodExpDte >= CURDATE()"); //return total count $PromoCode_exist = mysql_num_rows($results); //total records //if value is more than 0, promocode is valid if($PromoCode_exist) { echo json_encode(array("promoresult"=>"Promotion Code Valid", "promovalid"=>"Y")); exit(); }else{ echo json_encode(array("promoresult"=>"Invalid Promotion Code", "promovalid"=>"N")); exit(); }

  • jQuery cycle query

    - by Happy
    We have a script used for each .item: $(".item").each(function(){ item_link = "http://..."; block = $('.block', this); $.get(item_link, function(data) { var src = $('img.slide', data).attr('src'); block.html(src); }); }); item_link variable is uniquie for each query. There can be 100 .item or more. The problem is - server has limit on connections at the same time, that why some .item get var src, some not. The best solution is to use just one .get at the same time. I think there should be some counter, if .get is finished - it gives message "I'm finished, you can start" to the next .get and so on. How to do that? Thanks.

  • Can a link have both an onclick jquery and javascript event?

    - by odpogn
    I have a link that jQuery listens to, and if clicked it will toggle another div. The link also has an onclick javascript action. When I click the link, the div I want to toggle shows, but the javascript doesn't execute. Is it possible to get the javascript to execute AND have jQuery toggle the div? If so what would I put in the jQuery code to allow the link to execute the onclick javascript action? jQuery script $(function() { $('#links a').live('click', function() { $("#showall").toggle('slow'); }); }); my link <div id ="links"> <a href="some javascript" onclick="javascript">Play</a> </div>

  • Macros giving problems with dladdr()

    - by Veger
    I have implemented tracing behavior using the -finstrument-functions option of gcc and this (simplified) code: void __cyg_profile_func_enter(void *this_fn, void *call_site) { Dl_info di; if(dladdr(this_fn, &di)) printf("entered %s\n", (di.dli_sname?di_dli_sname:"<unknown>")); } This works great, except for one thing: macros are processed as well, but the function prints the information of the function which contains the macro. So functions containing macros have their information printed multiple times (which is of course undesired). Is there anything to detect that a macro is being processed? Or is is possible to turn off instrumenting macros at all? PS Same problems occur with sizeof()

  • What's the outcome if I use free with new or delete with malloc?

    - by skydoor
    It is a compiler error or runtime error? The code below can be compiled! class Base{ void g(); void h(); }; int main() { Base* p = new Base(); free(p); return 0; } However it can't be compiled with a virtual function if I declare the class Base like this class Base{ virtual void g(); void h(); }; The code below can be compiled all the time, no matter the function is virtual or not. class Base{ void g(); void h(); }; int main() { Base* p = (Base*)malloc(sizeof(Base)); delete p; return 0; }

  • speeding up parsing of files

    - by user248237
    the following function parses a CSV file into a list of dictionaries, where each element in the list is a dictionary where the values are indexed by the header of the file (assumed to be the first line.) this function is very very slow, taking ~6 seconds for a file that's relatively small (less than 30,000 lines.) how can I speed it up? def csv2dictlist_raw(filename, delimiter='\t'): f = open(filename) header_line = f.readline().strip() header_fields = header_line.split(delimiter) dictlist = [] # convert data to list of dictionaries for line in f: values = map(tryEval, line.strip().split(delimiter)) dictline = dict(zip(header_fields, values)) dictlist.append(dictline) return (dictlist, header_fields) thanks.

  • how to do collision detection for hollow(?) movieclips in flash AS3?

    - by Pieter888
    Hey everyone, I'm making small interactive games in flash to learn AS3, now I ran into a problem that I need some help with. I need to check the collision between the player and the wall which is normally simple using the hitTestObject function. But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object. So assuming that I'm correct about the error: How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?

  • Append an onClick event to an anchor tag using jquery?

    - by M.Woodard
    I am trying to add an onClick event to an anchor tag ... Previously i had ... <a href="somlink.html" onClick="pageTracker._link(this.href); return false;"> But i am trying to avoid the inline onClick event because it interferes with another script.. So using jQuery i am trying the following code ... <script> $(document).ready(function() { $('a#tracked').attr('onClick').click(function() {window.onbeforeunload = null; pageTracker._link(this.href); return false; }); }); </script> with the html like so <a id="tracked" href="something.html"> So my question is should this be working, and if not what would be the best solution?
