  • Is there a way to delete a form element without using jQuery .remove()?

    - by Tommy
    Using .remove() so that the select all check box is not submitted to the server. However, it is visible to the user as the select all checkbox is "physically" removed from the web page, upon submit. Instead, I would like removing the select all check box to appear seamless but NOT on the server side. i.e. - I would like to keep the input on the page but remove the element in the form array before it is sent. Can I manipulate the element[] array of the form before it is sent to the server and delete it there? Thank you.

  • Jquery dynamic dropdown event not firing

    - by kevin
    Hi i am trying to create dropdownlists dynamically and populating the contents via an ajax call, this sort of works in the sense that the drop down is created and populated as required but its 'change' event does not fire. I am posting the code below, if anyone can spot something obvious, can you please let me know regards $(document).ready(function () { $("#positions select").change(function (e) { alert("in"); var id = $("#category_id").val(); $.getJSON("/Category/GetSubCategories/" + id, function (data) { if (data.length > 0) { alert(data.length); var position = document.getElementById('positions'); var tr = position.insertRow(7); var td1 = tr.insertCell(-1); var td = tr.insertCell(-1); var sel = document.createElement("select"); sel.name = 'sel'; sel.id = 'sel'; sel.setAttribute('class', 'category'); td.appendChild(sel); $.each(data, function (GetSubCatergories, category) { $('#sel').append($("<option></option>"). attr("value", category.category_id). text(category.name)); }); } }); }); });

  • Onclick not added until after Postback

    - by Morph
    I have the following: <asp:Button id="SubmitButton" Text="Submit" runat="server" OnClientClick="Do();" OnClick="SubmitButton_Click"/> When the page is first rendered, I go to the view source in my browser and see that the onclick="Do();" is not added to my submit button tag. But when I do a post back, and do the view source again, the onclick is added to the submit. Why would the onclick not be there on the first request?

  • jQuery.get() - Practical uses?

    - by RedWolves
    I am trying to understand why you would use jQuery.get() and jQuery.get(index). The docs say it is to convert the jQuery selection to the raw DOM object instead of working with the selection as a jQuery object and the methods available to it. So a quick example: $("div").get(0).innerHTML; is the same as: $("div").html(); Obviously this is a bad example but I am struggling to figure when you would use .get(). Can you help me understand when I would use this method in my code?

  • Ignoring certain chars globally

    - by shi kui
    Consider it that '_'s in a number doesn't change that number's value so 1000==1_000==10_00. The Problem: given numbers like 1_244_23 1412_2 1_1111 etc..., how could I decide whether certain number appears in that collection? For example: 1244_23 yes, 11_111 yes, 1412_1 no. How could using regex to solve this? I mean, if I could tell the regex engine just ignore these '_''s when matching then this problem becomes trivial? How could I do so?

  • travesersing the dom with inexact parameters

    - by rashcroft23
    Hi, I want to grab the image src on a product page in a e commerce website. I'm writing this as a bookmarklet, so I'd like the code to work universally as possible. I've noticed that there are only two reoccurring factors in the product image tag among top e-commerce websites (amazon, bestbuy ect.): border=0 and 180<width&height<400. So how could I write a selector that would give me the srcof the first img element on the page with no border and width & height between 180 and 400 px? Or is there a better way of doing this? P.S. since I'm trying to keep the bookmarklet as light as possible, I don't want to use any libraries (jquery, yui etc)

  • How do I rotate a single object on an html 5 canvas?

    - by Kappers
    I'm trying to figure out how to rotate a single object on an html 5 canvas. For example: http://screencast.com/t/NTQ5M2E3Mzct - I want each one of those cards to be rotated at a different degree. So far, all I've seen are articles and examples that demonstrate ways to rotate the entire canvas. Right now, I'm guessing I'll have to rotate the canvas, draw an image, and then rotate the canvas back to it's original position before drawing the second image. If that's the case, then just let me know! I just have a feeling that there's another way. Anyone have any idea? Thanks in advance!

  • Email server; Is this method spam-safe?

    - by Camran
    I have a classifieds website, and on each classified there is a tip-form where users may tip a friend about the classified. The tip-forms' action is set to a php-page, which mails the email after sanitizing etc... I have to filter away spam etc so that my email-server don't get blacklisted or anything... I have my own server (VPS, Linux) and have thought about a solution... How does this sound to you: 1- Install a mail-server 2- Configure Firewall to ONLY allow connections to the mail-server from my website 3- Configure the mail-server so that a maximum of 'x' emails may be sent every 5 minutes or so 4- Create a php filter before sending the mail, which checks for 'bad' words. 5- If necessary, as last resort, ask the user a question (ex 5+5) before submitting form I would rather preferr if I didn't have to implement the 5th implementation above... What do you think? Also, another q I have that you may answer is: If an email-server gets blacklisted, is there any way to un-blacklist it? Or whats the solution if this happens? Thanks

  • node.js: encrypting data that needs to be decrypted?

    - by fancy
    We are using bcrypt for passwords and data that never needs to be decrypted. What should do to protect other user information that does. For this example lets say that we didn't want a users real name to be in plain text in case someone was to obtain the db. This is somewhat sensitive data but also needs to be called from time to time and displayed in plain text. Is there a simple way to do this?

  • Toggling between states on 3 containers in jQuery

    - by Saif Bechan
    Hello, i have an php/mysql/ajax auction application application. Now there is a section that can have 3 states. State one, the user can place a bid.(Bid button is shown) State two, the user has to wait before he can place a new bid(number of sec is shown) State three, the user has an auto bidding system enabled.(The price maximum and amount ate shown). Now i get these values trough jquery ajax, and i want to present the user the right section. Now the code i have is as follows: if(data[i].bidwait >= 0 && data[i].amount == ''){ // In this section the user has no autobiddings, and can place a bidding $(productContainer+' .bid-wrapper').removeClass('none'); $(productContainer+' .bidwait-wrapper').addClass('none'); $(productContainer+' .autobid-wrapper').addClass('none'); }else if(data[i].bidwait < 0 && data[i].amount == ''){ // In this section the user has to wait the amount of sec to place a new bid $(productContainer+' .bid-wrapper').addClass('none'); $(productContainer+' .bidwait-wrapper').removeClass('none'); $(productContainer+' .autobid-wrapper').addClass('none'); $(productContainer+' .bidwait-text').text(data[i].bidwait * -1); }else{ // In the last section the user has the auto bidder enabled, so that is shown $(productContainer+' .bid-wrapper').addClass('none'); $(productContainer+' .bidwait-wrapper').addClass('none'); $(productContainer+' .autobid-wrapper').removeClass('none'); $(productContainer+' .amount').html(data[i].amount == 0 ? '&#8734;' : data[i].amount); $(productContainer+' .maxprice').html(data[i].maxprice == 0 ? '&#8734;' : data[i].maxprice); } This looks like an awful lot of code for something so small. I was wondering if there is an easier method to accomplish such a thing. Speed is a huge issue for me because this has to run every second in the users browser. If there is no other option i am just going to remove this option and go with a no ajax approuch. If you have been, thank you for reading!

  • innerText/textContent vs. retrieving each text node

    - by J-P
    I've heard that using el.innerText||el.textContent can yield unreliable results, and that's why I've always insisted on using the following function in the past: function getText(node) { if (node.nodeType === 3) { return node.data; } var txt = ''; if (node = node.firstChild) do { txt += getText(node); } while (node = node.nextSibling); return txt; } This function goes through all nodes within an element and gathers the text of all text nodes, and text within descendants: E.g. <div id="x">foo <em>foo...</em> foo</div> Result: getText(document.getElementById('x')); // => "foo foo... foo" I'm quite sure there are issues with using innerText and textContent, but I've not been able to find a definitive list anywhere and I am starting to wonder if it's just hearsay. Can anyone offer any information about the possibly lacking reliability of textContent/innerText? EDIT: Found this great answer by Kangax -- http://stackoverflow.com/questions/1359469/innertext-works-in-ie-but-not-in-firefox/1359822#1359822

  • jQuery $().find problem

    - by Titanous
    I'm trying to get the contents of a XML document element, but the element has a colon in it's name. This line works for every element but the ones with a colon in the name: $(this).find("geo:lat").text(); I assume that the colon needs escaping. How do I fix this?

  • Issue creating side-by-side slideshows with jQuery

    - by JShweky
    I'm trying to create a site with 2 slideshows. I've tweaked and re-tweaked the JS and Jquery numerous times. Sometimes one slideshow works perfectly and the other cycles between one picture, other times both work but are out of sync, or the fadeIn doesn't seem to be applied to the second slideshow, or in some variations one slideshow stays frozen on the initial image and just remains static. Anyway, I created a JS Fiddle (link at bottom) and apparently my code is at least free of typos. JS is below, the rest is on the JS Fiddle. Any help would be greatly appreciated. $(document).ready(function () { $(".slider #1").fadeIn(1000); $(".slider #1").delay(2000).fadeOut(1000); var sc = $(".slider img").size(); var count = 2; setInterval(function () { $(".slider #" + count).fadeIn(1000); $(".slider #" + count).delay(2000).fadeOut(1000); if (count === sc) { count = 1; } else { count++; } }, 3500); $(".sliderTwo #7").fadeIn(1000); $(".sliderTwo #7").delay(2000).fadeOut(1000); var sc2 = 12; var count2 = 7; setInterval(function () { $(".sliderTwo #" + count2).fadeIn(1000); $(".sliderTwo #" + count2).delay(2000).fadeOut(1000); if (count2 === sc2) { count2 = 7; } else { count2++; } }, 3500); }); http://jsfiddle.net/gg4PL/

  • jquery to create array from form data

    - by AndrewStevens
    I've been wrestling with this problem for a couple hours now. Essentially, what I need to do is take the following or similar HTML: <div id="excpdivs"> <div class="excpdiv" id="excpdiv0"> Date: <input name="excp[0][date]"> Open: <input name="excp[0][open]"> Close: <input name="excp[0][close]"> </div> <div class="excpdiv" id="expdiv1"> Date: <input name="excp[1][date]"> Open: <input name="excp[1][open]"> Close: <input name="excp[1][close]"> </div> and get an array similar to the following to a php script: Array ( [0] => Array ( [date] => 2012-09-15 [open] => 3:00 [close] => 5:00 ) [1] => Array ( [date] => 2012-09-16 [open] => 2:00 [close] => 5:00 ) ) My main problem is getting the values from the input elements. My latest attempt is the following: var results = []; $(".excpdiv").each(function(){ var item = {}; var inpts = $(this).find("input"); item.date = $(inpts.get(0)).val(); item.open = $(inpts.get(1)).val(); item.close = $(inpts.get(2)).val(); results.push(item); }); Am I on the right track or am I hopelessly lost?

What am I missing?
