  • checking and replacing a value in an array jquery

    - by liz
    i have a table of data: <table id="disparities" class="datatable"> <thead> <tr> <th scope="col">Events</th> <th scope="col">White</th> <th scope="col">Black</th> <th scope="col">Hispanic</th><th scope="col">Asian/Pacific Islands</th> </tr> </thead> <tbody> <tr> <th scope="row">Hospitalizations</th> <td>0.00</td> <td>20</td> <td>10</td> <td>5</td> </tr> <tr> <th scope="row">ED Visits</th> <td>19</td> <td>90</td> <td>40</td> <td>18</td> </tr> </tbody> </table> i have a function that retrieves the values from the above table into an array like so (0.00,19) var points1 = $('#disparities td:nth-child(2)').map(function() { return $(this).text().match(/\S+/)[0]; }).get(); i want to check if there is a 0.00 value (or it could be just 0) and change that value to NA... so my resulting array is then (NA,19) not really sure how to go about this, whether in the initial match or as a separate action...

  • jQuery internals: Organization of the jQuery Object

    - by sonofdelphi
    I was going through the source code of jQuery. I'm having trouble understanding the wrapping strategy for the jQuery object. (function( window, undefined ) { // Define a local copy of jQuery var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); }, .... .... .... // Expose jQuery to the global object window.jQuery = window.$ = jQuery; })(window); Specifically, what I'm not able to understand stems from the first line. What is the outermost unnamed container function? Why is it required? Why is the container function anonymous? What is the need for the outermost '(' parantheses ?

  • How to match multiple substrings in jQuery combobox autocomplete

    - by John R
    I found more than a couple examples of this with a plain jquery autocomplete but not in a way that will work with the autocomplete included in the combobox code from the demo because the structure of the code is structured so differently. I want to match every item that has all of the search tokens anywhere in any word. I don't need to match the start of any word, any part of it is fine. I don't care if the search strings are highlighted in the autocomplete list if that makes things too complicated. Desired search/result combos: (please excuse the spacing) "fi th" "fi rst second th ird" "rs on" "fi rs t sec on d third" "ec rd" "first s ec ond thi rd" but not limited to any max/min length or number of tokens. EDIT I figured part of it out using the code structure from the other autocorrect I had working. source: function( requestObj, responseFunc ) { var matchArry = $("select > option").map(function(){return this.innerHTML;}).get(); var srchTerms = $.trim(requestObj.term).split(/\s+/); // For each search term, remove non-matches $.each (srchTerms, function (J, term) { var regX = new RegExp (term, "i"); matchArry = $.map (matchArry, function (item) { if( regX.test(item) ){ return{ label: item, value: item, option: HTMLOptionElement } ? item :null; } } ); }); // Return the match results responseFunc (matchArry); }, and select: function( event, ui ) { ui.item.option.selected = true; self._trigger( "selected", event, { item: ui.item.option }); $("destination").val(ui.item.value); // I added this line }, but I can't get both multiple words AND being able to click to select working at the same time. If I remove the } ? item :null; on the return in the map function I can click to select an item. If I leave it I can type multiple words, but I can't click any of the items... Is that the problem or the option: this? I've tried replacing it with HTMLOptionElement and null and I'm stuck. I am able to set the value of another field with ui.item.value within the select label but that doesn't put the value in the search box or close the dropdown menu. Fiddle of current code: http://jsfiddle.net/eY3hM/

  • How to integrate an dynamically generated JSON Object into an other object?

    - by Marco Ciarfaglia
    How can I put this JSON Object in the function or object below? // this function generates an JSON Object dynamically $(".n_ListTitle").each(function(i, v) { var node = $(this); var nodeParent = node.parent(); var nodeText = node.text(); var nodePrice = node.siblings('.n_ListPrice'); var prodPrice = $(nodePrice).text(); var prodId = nodeParent.attr('id').replace('ric', ''); var prodTitle = nodeText; var json = { id : prodId, price : prodPrice, currency : "CHF", name : prodTitle }; return json; }); TDConf.Config = { products : [ // here should be inserted the JSON Object {id: "[product-id1]", price:"[price1]", currency:"[currency1]", name:"[product-name1]"}, {id: "[product-id2]", price:"[price2]", currency:"[currency2]", name:"[product-name2]"}, ... })], containerTagId :"..." }; If it is not understandable please ask :) Thanks in advance for helping me to figure out!

  • jQuery if checkbox is checked to toggle classes

    - by Lynx
    I am needed to change my jQuery code up. Instead of the label toggling the class and showing the icon I need it to where if the checkbox is checked to show to toggle those classes. I have tried prop and is but I couldn't get them to work properly. The reason for the change is I want to preload data into the form and if it's going to be checked those toggles need to reflect that change. http://jsfiddle.net/70fbLooL/2/ EDIT Seems to be confusion as to exactly what I am trying to do. The fiddle I provided works perfectly fine. The problem is if I want to call the form from server-side and pre-populate the form the checkbox toggles will not show that they are checked because it's based on the clicked function. I need it to be based on if the checkbox equal true or checked. That way if the value equals true from the server-side call it will toggle those classes and look like it's checked.

  • I have a bunch of images being shown on click via JQuery - any easy way to animate this?

    - by Cenk
    This is the (quite simple) JS code I'm using: $(document).ready(function() { $(".button-list .next").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); nextimg = currentimg.next(); firstimg = project.find(".images-list li:first"); currentimg.removeClass("current"); if (nextimg.is("li")) nextimg.addClass("current"); else firstimg.addClass("current"); return false; }); $(".button-list .prev").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); previmg = currentimg.prev(); lastimg = project.find(".images-list li:last"); currentimg.removeClass("current"); if (previmg.is("li")) previmg.addClass("current"); else lastimg.addClass("current"); return false; }); }); And this is how the HTML code for the image list looks like: <ul class="images-list"> <li class="current"><img src="img/1.jpg" alt="" /></li> <li><img src="img/1b.jpg" alt="" /></li> </ul> <ul class="button-list"> <li><a class="button prev" href="#">?</a></li> <li><a class="button next" href="#">?</a></li></ul> The CSS: .images-list { height: 460px; list-style-type:none; float:left; width: 460px; overflow:hidden; position:relative; } .images-list img { height: 460px; width: 460px; display:block; } .images-list li { display:none; } .images-list li.current { display:block; } What I'd like to do is animate the images as they come and go - right now they just appear, which is OK but a bit more eye-candy would be nice. Can anyone help me out here? It it even possible to do it this way? Thanks!!

  • Inconsistent Loading Times for GeoRSS Overlay Between Firefox and IE

    - by Mark Fruhling
    I have a very simple page built to display a map and overlay a line based on points in a GeoRSS XML file. Here is the publicly accessible file. http://68.178.230.189/georssimport.html Firefox is loading in about 5 secs, which is expected because there are a lot of points to map, but IE (6 & 7) is taking upwards of 45 secs to a minute. What can I do to diagnose what is going on? What is a tool that will show me what is going on? (i.e. Firebug for IE) Thanks, Mark

  • Exceptions thrown in jQuery AJAX callbacks swallowed?

    Is there any way to handle exceptions thrown from AJAX callbacks in jQuery, other than adding a try..catch block to each callback?

  • How do you make an image opened in colorbox scrollable

    - by nicholas.alipaz
    I would like my images that I open in colorbox to be displayed fullsize with no resizing applied to them and then apply scrollbars to allow for viewing the larger images. Some of my images are quite tall and things get pixelated when resized down. Currently colorbox just resizes my images down to the size of the available height/width. Is there a way to make all images display fullsize with overflow scrollable in colorbox? I am linking directly to an image: <a href="/myimage.png" title="My Image" class="colorbox imagefield imagefield-imagelink imagefield-field_portfolio_screenshot initColorbox-processed cboxElement" rel="gallery-12"> <img src="/thumb/myimage.png" alt="image" title="My Image" class="imagecache imagecache-portfolio_screenshot_thumb" height="50" width="50"> </a>

  • Extjs - Getting more from the server

  • How atomic *should* I make an Ajax form?

    - by b. e. hollenbeck
    I have some web forms that I'm bringing over with AJAX, and as I was dealing with the database on the back end, I thought that it might be easier to just handle each input on the form atomically with AJAX, saving the form in 'real time' as the user edits it. The forms are ~20 fields of administrative settings. Would this create massive overhead with the app, cause it to be error-prone, or is this a feasible idea? Of course, contingent operations (like a checkbox that then requires a text entry) would be held until the textbox gained and lost focus. Comments?

  • Hide table row based on content of table cell

    - by timkl
    I want to make some jQuery that shows some table rows and hides others based on the content of the first table cell in each row. When I click a list item I want jQuery to check if the first letter of the item matches the first letter in any table cell in my markup, if so the parent table row should be shown and other rows should be hidden. This is my markup: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> <tr> <td>Beta1</td> <td>Some content</td> </tr> <tr> <td>Beta2</td> <td>Some content</td> </tr> <tr> <td>Beta3</td> <td>Some content</td> </tr> <tr> <td>Gamma1</td> <td>Some content</td> </tr> <tr> <td>Gamma2</td> <td>Some content</td> </tr> <tr> <td>Gamma3</td> <td>Some content</td> </tr> </table> So if I press "A" this is what is rendered in the browser: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> </table> I'm really new to jQuery so any hint on how to go about a problem like this would be appreciated :)

  • JS/CSS include section replacement, Debug vs Release

    - by Bayard Randel
    I'd be interested to hear how people handle conditional markup, specifically in their masterpages between release and debug builds. The particular scenario this is applicable to is handling concatenated js and css files. I'm currently using the .Net port of YUI compress to produce a single site.css and site.js from a large collection of separate files. One thought that occurred to me was to place the js and css include section in a user control or collection of panels and conditionally display the <link> and <script> markup based on the Debug or Release state of the assembly. Something along the lines of: #if DEBUG pnlDebugIncludes.visible = true #else pnlReleaseIncludes.visible = true #endif The panel is really not very nice semantically - wrapping <script> tags in a <div> is a bit gross; there must be a better approach. I would also think that a block level element like a <div> within <head> would be invalid html. Another idea was this could possibly be handled using web.config section replacements, but I'm not sure how I would go about doing that.

  • Regex with dynamic <textarea>

    - by Oscar Godson
    How can I do this with the JS replace() method: Make \n\n change to <p>$1</p> Change single \n to <br> Then back again. I think I have this part, see the JS at the bottom. Example HTML: <p>Hello</p><p>Wor<br>ld</p> The <textarea> would look like: Hello Wor ld So, how can I achieve this? It's an AJAX form where when you click on this div it changes to a <textarea> and back, and fourth, etc. So, I need to it to go from <p>s and <br>s to \n\n and \n. For the going to <textarea> from HTML I have: $(this).html().replace(/\s?<\/?(p|br\s?\/?)>\s?/g,"\n")

  • How to escape charaters in the title of a marker in a Google Maps?

    - by Anthony
    Say I have this piece of code: var marker = new google.maps.Marker({ position: location, title: 'B&#250;fals', map: map }); This creates a marker as expected but if I hover the mouse over it I don’t see 'Búfals' as I would expect (instead I see the html code). This doesn't make any difference: var marker = new google.maps.Marker({ position: location, title: unescape('B&#250;fals'), map: map }); Any ideas? Thanks.

  • Speeding up jQuery empty() or replaceWith() Functions When Dealing with Large DOM Elements

    - by Levi Hackwith
    Let me start off by apologizing for not giving a code snippet. The project I'm working on is proprietary and I'm afraid I can't show exactly what I'm working on. However, I'll do my best to be descriptive. Here's a breakdown of what goes on in my application: User clicks a button Server retrieves a list of images in the form of a data-table Each row in the table contains 8 data-cells that in turn each contain one hyperlink Each request by the user can contain up to 50 rows (I can change this number if need be) That means the table contains upwards of 800 individual DOM elements My analysis shows that jQuery("#dataTable").empty() and jQuery("#dataTable).replaceWith(tableCloneObject) take up 97% of my overall processing time and take on average 4 - 6 seconds to complete. I'm looking for a way to speed up either of the above mentioned jQuery functions when dealing with massive DOM elements that need to be removed / replaced. I hope my explanation helps.

  • jQuery - I'm getting unexpected outputs from a basic math formula.

    - by OllieMcCarthy
    Hi I would like to start by saying I'd greatly appreciate anyones help on this. I have built a small caculator to calculate the amount a consumer can save annually on energy by installing a ground heat pump or solar panels. As far as I can tell the mathematical formulas are correct and my client verified this yesterday when I showed him the code. Two problems. The first is that the calculator is outputting ridiculously large numbers for the first result. The second problem is that the solar result is only working when there are no zeros in the fields. Are there some quirks as to how one would write mathematical formulas in JS or jQuery? Any help greatly appreciated. Here is the link - http://www.olliemccarthy.com/test/johncmurphy/?page_id=249 And here is the code for the entire function - $jq(document).ready(function(){ // Energy Bill Saver // Declare Variables var A = ""; // Input for Oil var B = ""; // Input for Storage Heater var C = ""; // Input for Natural Gas var D = ""; // Input for LPG var E = ""; // Input for Coal var F = ""; // Input for Wood Pellets var G = ""; // Input for Number of Occupants var J = ""; var K = ""; var H = ""; var I = ""; // Declare Constants var a = "0.0816"; // Rate for Oil var b = "0.0963"; // Rate for NightRate var c = "0.0558"; // Rate for Gas var d = "0.1579"; // Rate for LPG var e = "0.121"; // Rate for Coal var f = "0.0828"; // Rate for Pellets var g = "0.02675"; // Rate for Heat Pump var x = "1226.4"; // Splittin up I to avoid error var S1 = ""; // Splitting up the calcuation for I var S2 = ""; // Splitting up the calcuation for I var S3 = ""; // Splitting up the calcuation for I var S4 = ""; // Splitting up the calcuation for I var S5 = ""; // Splitting up the calcuation for I var S6 = ""; // Splitting up the calcuation for I // Calculate H (Ground Sourced Heat Pump) $jq(".es-calculate").click(function(){ $jq(".es-result-wrap").slideDown(300); A = $jq("input.es-oil").val(); B = $jq("input.es-storage").val(); C = $jq("input.es-gas").val(); D = $jq("input.es-lpg").val(); E = $jq("input.es-coal").val(); F = $jq("input.es-pellets").val(); G = $jq("input.es-occupants").val(); J = ( A / a ) + ( B / b ) + ( C / c ) + ( D / d ) + ( E / e ) + ( F / f ) ; H = A + B + C + D + E + F - ( J * g ) ; K = ( G * x ) ; if ( A !== "0" ) { S1 = ( ( ( A / a ) / J ) * K * a ) ; } else { S1 = "0" ; } if ( B !== "0" ) { S2 = ( ( ( B / b ) / J ) * K * b ) ; } else { S2 = "0" ; } if ( C !== "0" ) { S3 = ( ( ( C / c ) / J ) * K * c ) ; } else { S3 = "0" ; } if ( D !== "0" ) { S4 = ( ( ( D / d ) / J ) * K * d ) ; } else { S4 = "0" ; } if ( E !== "0" ) { S5 = ( ( ( E / e ) / J ) * K * e ) ; } else { S5 = "0" ; } if ( F !== "0" ) { S6 = ( ( ( F / f ) / J ) * K * f ) ; } else { S6 = "0" ; } I = S1 + S2 + S3 + S4 + S5 + S6 ; if(!isNaN(H)) {$jq("span.es-result-span-h").text(H.toFixed(2));} else{$jq("span.es-result-span-h").text('Error: Please enter numerals only');} if(!isNaN(I)) {$jq("span.es-result-span-i").text(I.toFixed(2));} else{$jq("span.es-result-span-i").text('Error: Please enter numerals only');} }); });
