• How to return radio checked object with jQuery ?

  - by Kim

  HTML <input type="radio" name="rdName" id="uniqueID1" value="1" checked="checked"> <input type="radio" name="rdName" id="uniqueID2" value="2"> <input type="radio" name="rdName" id="uniqueID3" value="3"> jQuery #1 $('input:radio[name=rdName]:checked').val(); jQuery #2 $('input[name=rdName]:checked'); jQuery #1 gets the value of checked radio, but I need to get the whole object to get the ID. jQuery #2 get this (from Chrome Dev console).

• 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/

• Storing arbitrary data in HTML

  - by Rob Colburn

  What is the best way to embed data in html elements for later use? As an example, let's say we have jQuery returning some JSON from the server, and we want to dump that datat out to the user as paragraphs. However, we want to be able to attach meta-data to these elements, so we can events for these later. The way I tend to handle this, is with some ugly prefixing function handle_response(data) { var html = ''; for (var i in data) { html += '<p id="prefix_' + data[i].id + '">' + data[i].message + '</p>'; } jQuery('#log').html(html).find('p').click(function(){ alert('The ID is: ' + $(this).attr('id').substr(7)); }); } Alternatively, one can build a Form in the paragraph, and store your meta-data there. But, that often feels like overkill. This has been asked before in different ways, but I do not feel it's been answered well: http://stackoverflow.com/questions/432174/how-to-store-arbitrary-data-for-some-html-tags http://stackoverflow.com/questions/209428/non-standard-attributes-on-html-tags-good-thing-bad-thing-your-thoughts

• How does jQuery store data with .data()?

  - by TK

  I am a little confused how jQuery stores data with .data() functions. Is this something called expando? Or is this using HTML5 Web Storage although I think this is very unlikely? The documentation says: The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. As I read about expando, it seems to have a rick of memory leak. Unfortunately my skills are not enough to read and understand jQuery code itself, but I want to know how jQuery stores such data by using data(). http://api.jquery.com/data/

• RegEx to replace html entities

  - by DeltaFox

  Hi, all. I'm looking for a way to replace the bullet character in Greasemonkey. I assume a Regular Expression will do the trick, but I'm not as well-versed in it as many of you. For example, "SampleSite.com • Page Title" becoming "SampleSite.com Page Title". The issue is that the character has already been parsed by the time Greasemonkey has gotten to it, and I don't know how to make it recognize the symbol. I've tried these so far, but they haven't worked: newTitle = document.title.replace(/•/g, ""); newTitle = document.title.replace("•", ""); //just for grins, but didn't work anyway

• Can I disable SOP (Same Origin Policy) on any browser for development?

  - by Thomaschaaf

  I want to develop JS on my windows machine. Do you know a browser where I can turn off SOP so I can develop? Firefox would be optimal. Or if you know a proxy I could use for a SOAP/WSDL site it would be great too.. I am trying to work with the SOAPClient (http://www.codeplex.com/JavaScriptSoapClient)

• Cannot set property X of undefined - programatically created element

  - by Dave

  I am working on a class to create a fairly complex custom element. I want to be able to define element attributes (mainly CSS) as I am creating the elements. I came up with the below function to quickly set attrs for me given an input array: // Sample array structure of apply_settings //var _button_div = { // syle : { // position: 'absolute', // padding : '2px', // right : 0, // top : 0 // } //}; function __apply_settings(__el,apply_settings){ try{ for(settingKey in apply_settings){ __setting = apply_settings[settingKey]; if(typeof(__setting)=='string'){ __el[settingKey] = __setting; }else{ for(i in __setting){ __el[settingKey][i] = apply_settings[settingKey][i]; } } } }catch(ex){ alert(ex + " " + __el); } } The function works fine except here: function __draw_top(){ var containerDiv = document.createElement('div'); var buttonDiv = document.createElement('div'); __apply_settings(containerDiv,this.settings.top_bar); if(global_settings.show_x) buttonDiv.appendChild(__create_img(global_settings.images.close)); containerDiv.appendChild(buttonDiv); __apply_settings(buttonDiv,this.settings.button_div); return containerDiv; } The specific section that is failing is __apply_settings(buttonDiv,this.settings.button_div); with the error "Cannot set property 'position' of undefined". So naturally, I am assuming that buttonDiv is undefined.. I put alert(ex + " " + __el); in __apply_settings() to verify what I was working with. Surprisingly enough, the element is a div. Is there any reason why this function would be working for containerDiv and not buttonDiv? Any help would be greatly appreciated :) {EDIT} http://jsfiddle.net/Us8Zw/2/

• How can I force input to uppercase in an asp.net textbox?

  - by Aheho

  I'm writing an asp.net application. I have a textbox on a webform and I want to force whatever the user types to upper case. I'd like to do this on the front end. You should also note that there is a validation control on this textbox, so I want to make sure the solution doesn't interfere with the asp.net validation. Clarification: It appears that the CSS text-tranform makes the user input appear in uppercase, however under the hood, it's still lower case as the validation control fails. You see, my validation control checks to see if a valid state code is entered, however the regex expression I"m using only works with uppercase characters.

• Event problems with FF

  - by s4v10r

  Hi all :) Made this sweet little script to auto change fields after input. Works nicely in IE, Chrome and Safari, but not in FF or opera. JS code: function fieldChange(id, e){ var keyID = (window.event) ? event.keyCode : e.keyCode; if (document.getElementById(id).value.length >= 2){ if (keyID >= 48 && keyID <= 57 || keyID >= 96 && keyID <= 105){ switch(id){ case "textf1": document.getElementById("textf2").focus(); break; case "textf2": document.getElementById("textf3").focus(); break; case "textf3": if (document.getElementById(id).value.length >= 4){ document.getElementById("nubPcode").focus(); } break; } } } HTML: <div class="privateOrderSchema"> <input type="text" id="textf1" name="textf1" maxlength="2" size="4" onKeyUp="fieldChange('textf1')"/>- <input type="text" id="textf2" name="textf2" maxlength="2" size="4" onKeyUp="fieldChange('textf2')" />- <input type="text" id="textf3" name="textf3" maxlength="4" size="5" onKeyUp="fieldChange('textf3')" /> </div> <div class="privateOrderSchema"> <input type="text" id="nubPcode" name="nubPcode" size="4" maxlength="4" /> <br /> </div> Does anybody know how to send the "e" var in this scenario? Tnx all :D ur gr8!

• iframe/lightbox refresh issues

  - by user96828

  Hi Please check out: http://gherkin.co.nz/refresh/ and click on the purple box that says 'Membership chest' You should then see some form fields in an iframe in the lightbox. If you click on the "GO" button, the page will change (currently Not found, which is fine for now). If you click the dark area to close the box, then click the purple card again - it will take you back to the not found page. When called, I want the content to always go back to the page specified in the iframe src, not the last page. Can it go back to the first specified page on this second click? Does that make sense? basically I want the iframe/lightbox to refresh its content each time it is called.

• Suppose i have an HTML table. How do I use JQuery events on this?

  - by alex

  <table> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> </table> How do I make the appropriate col1 fill with the letters "ABC" when the user rollovers the row? And then disappear the "ABC" when the user moves the mouse away from that row? So far, I got this. I solved it. $(".ep").hover(function(){ $(this).find('td.playButtonCol').html('PLAY'); },function(){ $(this).find('td.playButtonCol').html(''); });

• Rotate a feature Image in Open Layers

  - by Ozaki

  I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

  I'm trying to save dynamically created elements in my application.js file to the database. Would the code look something like this?: $.ajax({ type: "POST", data: { title: 'oembed.title', thumbnail_url: 'oembed.thumbnail_url'} }); Is there anything I'm missing? Assume that oembed.title and oembed.thubnail_url hold the values I want to save, and that title and thumbnail are the database columns.

• Jqyery Bugs?? Long decimal number after two numbers multiply...

  - by Jerry

  Hi all I am working on a shopping site and I am trying to calculate the subtotal of products. I got my price from a array and quantity from getJSON response array. Two of them multiply comes to my subtotal. I can change the quantity and it will comes out different subtotal. However,when I change the quantity to certain number, the final subtotal is like 259.99999999994 or some long decimal number. I use console.log to check the $price and $qty. Both of them are in the correct format ex..299.99 and 6 quantity.I have no idea what happen. I would appreciate it if someone can help me about it. Here is my Jquery code. $(".price").each(function(index, price){ $price=$(this); //get the product id and the price shown on the page var id=$price.closest('tr').attr('id'); var indiPrice=$($price).html(); //take off $ indiPrice=indiPrice.substring(1) //make sure it is number format var aindiPrice=Number(indiPrice); //push into the array productIdPrice[id]=(aindiPrice); var url=update.php $.getJSON( url, {productId:tableId, //tableId is from the other jquery code which refers to qty:qty}, productId function(responseProduct){ $.each(responseProduct, function(productIndex, Qty){ //loop the return data if(productIdPrice[productIndex]){ //get the price from the previous array we create X Qty newSub=productIdPrice[productIndex]*Number(Qty); //productIdPrice[productIndex] are the price like 199.99 or 99.99 // Qty are Quantity like 9 or 10 or 3 sum+=newSub; newSub.toFixed(2); //try to solve the problem with toFixed but didn't work console.log("id: "+productIdPrice[productIndex]) console.log("Qty: "+Qty); console.log(newSub); **//newSub sometime become XXXX.96999999994** }; Thanks again!

• WCF webHttpBinding with jQuery AJAX - removing/working around same origin policy

  - by csauve

  So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.
