  • Modify onclick function with jQuery

    - by Chris Barr
    I've got a button that has an onclick event in it, which was set on the back end from .NET. Beside it is a checkbox <button class="img_button" onclick="if(buttonLoader(this)){WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('uxBtnRelease', '', true, '', 'somepage.aspx?oupid=5&fp=true', false, true))} return false;" type="button">Release</button> <input type="checkbox" checked="checked" id="myCheckbox"> When the checkbox is clicked, needs to change the value of the query string in the URL inside the onclick function of the button. So far I have this, and the idea is right, but I keep getting errors when it's run: "Uncaught SyntaxError: Unexpected token ILLEGAL" var defaultReleaseOnClick=null; $("#myCheckbox").click(function(){ var $releaseBtn = $(".img_button"); if(defaultReleaseOnClick==null) defaultReleaseOnClick=$releaseBtn.attr("onclick"); var newOnClickString = defaultReleaseOnClick.toString().replace(/&fp=[a-z]+'/i,"&fp="+this.checked); $releaseBtn.removeAttr("onclick").click(eval(newOnClickString)); }); I know it seems kinda hacky to convert the function to a string, do a replacement, and then try to convert it back to a function, but I don't know any other way to do it. Any ideas? I've set up a demo here: http://jsbin.com/asiwu4/edit

  • Detecting position with drag-and-drop and jQuery?

    - by Matthew Westrik
    Hi, I need to know how to detect the position of a dragged item as opposed to other divs. I need to detect whether an item is dropped outside of two different divs. (I am building a mac dock type start page and I need to know how to do this so I can delete icons by dragging them off the bar.) Any help would be greatly appreciated.

  • Add class to textbox when invalid, using .Net Validators

    - by CoreyT
    I'm working on a multipage form in .Net using AJAX (UpdatePanels). I am stuck right now trying to get a class added to the textbox that is invalid to basically highlight it red. I found a sample online using this code: $("span.invalid").bind("DOMAttrModified propertychange", function (e) { // Exit early if IE because it throws this event lots more if (e.originalEvent.propertyName && e.originalEvent.propertyName != "isvalid") return; var controlToValidate = $("#" + this.controltovalidate); var validators = controlToValidate.attr("Validators"); if (validators == null) return; var isValid = true; $(validators).each(function () { if (this.isvalid !== true) { isValid = false; } }); if (isValid) { controlToValidate.removeClass("invalid"); } else { controlToValidate.addClass("invalid"); } }); That works perfectly, in IE only. For some reason this code does not ever fire in Firefox. I've looked up the DOMAttrModified event and it sounds like this should work in Firefox, hence it being in the code. I must be missing something though because it does not work. I'm open to other solutions for what I am trying to accomplish here if anyone has something good. Basically the form is 3 pages right now. Page 1 has a variable number of fields that require validation. It could be 5, or 13 fields, based on a checkbox. Page 2 has another set of fields that need to be validated separately. Obviously when I am on page 1 it should not try to validate page 2, and vice versa. Pleas help with either some help to fix the code I have, or an alternative.

  • Ajax basic email code without reloading page

    - by Camran
    I have in a previous Q found out that I need an ajax-function to send an email (submit a contact form) without reloading the page. This is for my classifieds website, where when users are viewing a classified they have the option to "tip a friend" by entering their friends email-adress and submitting the form. But I don't want to reload the page, that would be frustrating and not so clever. The only input in the form is a text input which will contain the email-adress to send to, and another hidden input which contains the classified_id nr, to identify which classified it is. The website is php based btw... Does anybody have a simple script for this? I have no experience in Ajax at all... And would really appreciate it. Thanks PS: Would prefer no Jquery, due to clients own reasons...

  • CKEditor plugin: Hightlight selected text by hovering on a new item in the toolbar and selecting fro

    - by scottystang
    I'm new to the CKEditor and I'm trying to create a simple plugin. What I'm hoping to accomplish is to allow the user to highlight some text and then hover on a new item in the toolbar that drops down on mouse over a few different highlight color options for the text. For example, the user could highlight some text, hover on my new item and then select a highlight color. This will be similar to the 'BGColor' plugin except instead of opening a color palette to choose from, the user would select from a drop down of options similar to when you choose to change the font size you have a list of options such as '10', '11', '12', etc. Any help would be appreciated on how to pull this off. I was hoping to check out how 'BGColor' and 'FontSize' plugins where implemented, but I can't find these in ../ckeditor/_source/plugins. Am I looking in the right spot? Also, the link for plugins here - http://docs.cksource.com/CKEditor_3.x/Developers_Guide isn't clickable so I'm not sure if there's a place for plugin documentation that I can check out.

  • Proper Regex to find and replace escaped UTF-8 strings

    - by Piet Binnenbocht
    (edited) I am reading a JSON file that includes some UTF-8 characters that are encoded like this: "\uf36b". I am trying to write a RegExp to convert this to an HTML entity that looks like "&#x1F36B;". This displays the character correctly in my html page. I haven't been able to correctly display the character that should be associated with "\uf36b", especially when in a longer sentence that also includes other text. How can I write a regexp that replaces strings like "\uf4d6" and "\uf36b" but leaves other text alone? Example: var str = "I need \uf36b #chocolate"; This should be converted to: I need &#x1F36B; #chocolate;

    - by alex
    In a sort of follow up to this question, I have another problem in IE8.

Of course, the good guys (Firefox/Safari/etc) display it perfectly. How do I fix this? Thanks UPDATE Should I just got with a new Lightbox?

  • Question of using static_cast on "this" pointer in a derived object to base class

    - by Johnyy
    Hi, this is an example taken from Effective C++ 3ed, it says that if the static_cast is used this way, the base part of the object is copied, and the call is invoked from that part. I wanted to understand what is happening under the hood, will anyone help? class Window { // base class public: virtual void onResize() { } // base onResize impl }; class SpecialWindow: public Window { // derived class public: virtual void onResize() { // derived onResize impl; static_cast<Window>(*this).onResize(); // cast *this to Window, // then call its onResize; // this doesn't work! // do SpecialWindow- } // specific stuff };

  • Is Bootstrap 2.1 compatible with jQuery UI?

    - by Ghopper21
    It's a known problem that the older Bootstrap didn't work out of the box with jQuery UI, as you can see from this github discussion. There are a few mashups of the two, including jQuery Bootstrap by John Seigers and jQuery UI Bootstrap by Addy Osmani. Are those mashups still necessary with the new version of Bootstrap, or can you now just use Bootstrap and jQuery UI out of the box (as is alluded to vaguely in the github discussion)?

  • Looping through Markers with Google Maps API v3 Problem

    - by Oscar Godson
    I'm not sure why this isn't working. I don't have any errors, but what happens is, no matter what marker I click on, it clicks the 3rd one (which is the last one out of 4 markers. Array starts at 0, obviously) and shows the number "3", which is correct for THAT one, but I'm not clicking that one. Here is most of my code, just not the array of [place-name, coordinates] (var locations, which you will see): function initialize() { var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 15, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); var infowindow = new Array(); var marker = new Array(); for(x in locations){ console.log(x); infowindow[x] = new google.maps.InfoWindow({content: x}); marker[x] = new google.maps.Marker({title:locations[x][0],map:map,position:locations[x][1]}); google.maps.event.addListener(marker[x], 'click', function() {infowindow[x].open(map,marker[x]);}); } } initialize() The console.log output is (its correct, and what i expect): 0 1 2 3 So, any ideas?

  • innerHTML of dynamically added element not updating in Chrome

    - by Sara Chipps
    I'm modifying a dynamically created input element by setting the innerHTML, when I view the element in the DOM Inspector I can see that the values I passed are in the input. However, I can't see it on the page? Is there a refresh() function that I should be calling after setting the value? I have tried innerText, and value and gotten the same results. Here is how I am setting it: $("input[name='group']")[0].innerHTML = groups; (as far as the JS set and the JQuery selector I have found chrome plugins to be fickle this way)

  • AJAX, same-origin Policy and working XML Requests

    - by Joern
    Hello guys, so, currently I develop Widgets for Smartphones and am going a bit more advanced into fields of data exchange between client and server applications. My problem is: For my current project I want my client file to request data from a PHP script with the help of AJAX XmlHttpRequest and the POST method: function xmlRequestNotes() { var parameter = 'p=1234'; xmlhttp = new XMLHttpRequest(); xmlhttp.open("POST", url, true); // Http Header xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", parameter.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { json = JSON.parse(xmlhttp.responseText); // Doing Stuff with the Response } }; xmlhttp.send(parameter); } This works perfectly fine on my local server set up in XAMPP and the local Widget emulator. But if it gets onto the device (also with access to the target network) I receive the 101 Network Error. And as far as I have read, this is due to the "Same-Origin Policy" of XmlHttpRequests? My problem is to really understand that. Although the idea of this policy is clear to me, I'm a bit confused by the fact that another XmlHttpRequest for a Yahoo Weather XML Feed works fine. Now, could anyone be so helpful to enlighten me? Here is the request that returns a city name from Yahoo's weather feed: function getCityName() { xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", "http://weather.yahooapis.com/forecastrss?w=645458&u=c", true); xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { xmlhttp.responseXML; var yweather = "http://xml.weather.yahoo.com/ns/rss/1.0"; alert(xmlhttp.responseXML.getElementsByTagNameNS(yweather, "location")[0].getAttribute("city")); } }; xmlhttp.send(null); } Obvious differences are the POST and GET methods for once, but seeing that the Same-Origin Policy takes effect no matter what method, I can't really make much sense of it. Why does the latter request work but not the first? I would really appreciate some help here. Greetings and a merry Christmas to you guys!

  • Fatal error with Custom Magento Module on one server but not the other

    - by Jack
    Hi, I am creating my own custom module in Magento and during testing on a Litespeed server (PHP v5.2.14) I am getting a Fatal Error: Call to a member function batch() on a non-object in ../../../BatchController.php on line 25 that was not appearing during testing on another linux server and a wamp server (PHP v5.2.11). This one has stumped me. I am guessing it has something to do with the server configuration rather than the code itself. But i am just guessing. I was hoping someone here could tell me. The only real major difference I could see, aside from the php versions and environment, is that the server that the error is on is using the Suhosin Patch. But would that be something that could cause this? The line in question is Mage::getModel('mymodule/mymodel')->batch(); which is enclosed in an IF statement. batch() is a public function located in my model file. If you need more code let me know. Thanks!

  • Address String Split in javscript

    - by Arasoi
    Ok folks I have bombed around for a few days trying to find a good solution for this one. What I have is two possible address formats. 28 Main St Somecity, NY 12345-6789 or Main St Somecity, Ny 12345-6789 What I need to do Is split both strings down into an array structured as such address[0] = HousNumber address[1] = Street address[2] = City address[3] = State address[4] = ZipCode My major problem is how to account for the lack of a house number. with out having the whole array shift the data up one. address[0] = Street address[1] = City address[2] = State address[3] = ZipCode [Edit] For those that are wondering this is what i am doing atm . (cleaner version) place = response.Placemark[0]; point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]); FCmap.setCenter(point,12); var a = place.address.split(','); var e = a[2].split(" "); var x = a[0].split(" "); var hn = x.filter(function(item,index){ return index == 0; }); var st = x.filter(function(item,index){ return index != 0; }); var street = ''; st.each(function(item,index){street += item + ' ';}); results[0] = new Hash({ FullAddie: place.address, HouseNum: hn[0], Dir: '', Street: street, City: a[1], State: e[1], ZipCode: e[2], GPoint: new GMarker(point), Lat: place.Point.coordinates[1], Lng: place.Point.coordinates[0] }); // End Address Splitting
