  • When I try to pass large amounts of information using jquery $.ajax(post) method. it throws potenti

    - by dotnetrocks
    I am trying to create a preview window for my texteditor in my blog page. I need to send the content to the server to clean up the text entered before I can preview it on the preview window. I was trying to use $.ajax({ type: method, url: url, data: values, success: LoadPageCallback(targetID), error: function(msg) { $('#' + targetID).attr('innerHTML', 'An error has occurred. Please try again.'); } }); Whenever I tried to click on the preview button it returns an XMLHTTPRequest error. The error description - Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. The ValidateRequest for the page is set to false. Is there a way I can set validaterequest to false for the ajax call.Please advise Thank you for reading my post.

  • jQuery - How to Use slideDown (or show) function on a table row?

    - by Greg
    I'm trying to add a row to a table and have that row slide into view, however the slidedown function seems to be adding a display:block style to the table row which messes up the layout. Any ideas how to work around this? Here's the code: $.get('/some_url',{'val1':id}, function(data){ var row = $('#detailed_edit_row'); row.hide(); row.html(data); row.slideDown(1000); });

  • Is there an alias for 'this' in TypeScript?

    - by Todd
    I've attempted to write a class in TypeScript that has a method defined which acts as an event handler callback to a jQuery event. class Editor { textarea: JQuery; constructor(public id: string) { this.textarea = $(id); this.textarea.focusin(onFocusIn); } onFocusIn(e: JQueryEventObject) { var height = this.textarea.css('height'); // <-- This is not good. } } Within the onFocusIn event handler, TypeScript sees 'this' as being the 'this' of the class. However, jQuery overrides the this reference and sets it to the DOM object associated with the event. One alternative is to define a lambda within the constructor as the event handler, in which case TypeScript creates a sort of closure with a hidden _this alias. class Editor { textarea: JQuery; constructor(public id: string) { this.textarea = $(id); this.textarea.focusin((e) => { var height = this.textarea.css('height'); // <-- This is good. }); } } My question is, is there another way to access the this reference within the method-based event handler using TypeScript, to overcome this jQuery behavior?

  • jQuery.data() works in Mac OS WebKit, but not on iPhone OS?

    - by rpj
    I'm playing around with jQTouch for an iPhone OS app that I've been toying with off and on for a while. I wanted to try my hand building it as a web app so I started playing with jQTouch. For reference, here is the page+source (all my code is currently in index.html so you can just "View Source" to see it all): http://rpj.me/doughapp.com/wd/ Essentially, I'm trying to save pertinent JSON objects retrieved from Google Local into DOM objects using the data() method (in this example, obj is the Google Local object): $('#locPane').data('selected', obj); then later (in a different "pane"), retrieving that object to be used: $('#locPane').bind('pageAnimationEnd', function(e, inf) { var selobj = $(this).data('selected'); // use 'selobj' here ... } In Chromium and Safari on the desktop OS (Snow Leopard in my case), this works perfectly (try it out). However, the same code returns undefined for the call to $(this).data('selected') in the second snippet above. I've also tried $('#' + e.target.id).data('selected') and even the naive $('#locPane').data('selected'). All variants return undefined in the iPhone OS version of WebKit, but not on the desktop. Interestingly, the running this on Mobile Safari in the iPhone Simulator fails as well. If you look at the full source, you'll see that I even try to save this object into my global jQTouch object (named jqt in my code). This, too, fails on the mobile platform. Has anyone else ever ran into this? I'll admit to not being a web/javascript programmer by trade, so if I'm making an idiot's error please call me out on it. Thank you in advance for the help! -RPJ Update: I didn't make it clear in the original post, but I'm open to any workaround if it works consistently. Since I'm having trouble storing these objects in general, anything that allows me to keep them around is good enough for now. Thanks!

  • firefox does not load large size images

    - by Pradeep
    I am stuck with a kind of bug in FF, wherein it’s unable to load images of big size (I have 8 MB size of image) from the server. The loading of image is all fine on IE. I am still looking out for ways to get rid of this problem. I changed server(IIS) settings to allow bigger file sizes. Also, I used “load” event on image using JQuery and tried all sort of options listed here http://api.jquery.com/load-event/, but nothing worked so far. If anyone of you has come across any such similar problem, and a way to resolve it, it would be nice to hear from you Please note: high resolution images are part of the requirement. Code : <style> img { background-color: #FFFFFF; background-image: url(http://eremurus.hyd:8080/QMS/plugin/imagepanner/loader.gif); background-repeat: no-repeat; background-position: center center; } </style> <script src="../plugin/jquery-ui-1.8.7.custom/js/jquery-1.4.4.min.js" type="text/javascript"></script> <script> jQuery(document).ready(function($){ ///var _url = "http://eremurus.hyd:8080/QMS/plugin/imagepanner/floorPlan.jpg"; // set up the node / element _im =$("#main"); //_im.bind("load",function(){ $(this).fadeIn(); }); // set the src attribute now, after insertion to the DOM //_im.attr('src',_url); $("#main").one("load",function(){ alert('loaded'); }) .each(function(){ if(this.complete){ $(this).trigger("load"); } }); }); </script> </head> <body> <div id="target"><img id='main' src="http://eremurus.hyd:8080/QMS/plugin/imagepanner/floorPlan.jpg"> </img></div> </body> </html>

  • Jquery: encasing div and anchor link binded to same event.

    - by centr0
    im having trouble figuring out how to bind mouseout() to my entire nav bar including the links. when a user hovers over a link in #nav a sub menu is shown. all is well there. what i want to do is fadeOut that sub menu when the user hovers out of the entire #nav. my code for the mouseout: $('#nav').mouseout(function() { setTimeout(function() { //$('.sub-link').fadeOut(); }, 2000); }); when i hover over an anchor link which resides in #nav, i see the sub-menu. then i guess the mouseout() even fires and the sub-menu fades out. is there anyway to have the #nav and any anchor links within it to act as one? i'd paste my markup but even indenting it 4 spaces still shows as rendered html.. TIA

  • is there a way to add a variable/property to a DOM element (eg, an element returned by a jQuery sele

    - by bt
    Hi there, I am looking for an alternative to using an object/variable in global scope -- I would like to associate key/value pairs with specific DOM elements (eg, a DIV), so that I can use them as input for logic that processes other elements (eg, child elements of said DIV). I tried something naive like: $('[foo=bar]').key='value' , and $('[foo=bar]')[key]='value', but it puked. Doing something like: var foobar = $('[foo=bar]'); foobar.key = 'value' -- works, but the new property/value only affects the new object (ie, foobar, not $('[foo=bar]')) Most likely there's something terribly basic I am overlooking. Any help is appreciated, thanks!

  • How to append html only if the div is empty in jQuery?

    - by johnnyb3000
    I have this code for displaying content for login and registration in my PHP file: <?php // LOGIN PART ?> <div class="login-part"></div> <?php // REGISTRATION PART ?> <div class="registration-part"></div> And this in my js file: $(document).ready( function() { // FOR REGISTRATION $('span.logreg.reg').click(function () { $('div.registration-part').append('<p>Registration</p>'); }); // FOR LOGIN $('span.logreg.log').click(function () { // insert html $('div.login-part').append('<p>Login</p>'); }); }); Now, everytime I click on a span it shows the text login or registration, according to which of the span was clicked. Thats OK, however I need to add it only once, so when the user click more times on the span it will be not adding more text. Remove() or empty() is not an option, as far as I know, because I need the information inside input boxes (there will be input boxes later for inserting user info) to stay there and not be deleted if the user click accidentally on the span again. It can however delete the html inside the div, if he clicks on another span. E.g. if span.log is active, after clicking on span.log nothing happens, but if he clicks on span.reg the html inside div.login-part will be removed and registration text will appear. How to do something like this?

  • How to make div follow scrolling smoothly with jQuery?

    - by Martti Laine
    Hello I'm creating a blog layout, which has an sidebar. In sidebar there are sections/boxes, but the last one of these boxes should follow scrolling when none of the other boxes are visible. So, when user scrolls down, he sees a normal sidebar, but when user has went down enough, sidebar ends but the last box starts to follow on the top of the screen. I have seen this a lot on different kind of sites. So hard to explain with my english. I already made it to follow screen smoothly with animate() but couldn't get it like this. Hope you understood. I already tried in Google for almost an hour but couldn't figure out any keywords (due to my bad english). EDIT: My code at the moment: $(window).scroll(function(){ $.each($('.follow-scroll'),function(){ var eloffset = $(this).offset(); var windowpos = $(window).scrollTop(); if(windowpos<eloffset.top) { var finaldestination = 0; } else { var finaldestination = windowpos; } $(this).stop().animate({'top':finaldestination},200); }); });

  • check for a span class content and then update the quantity using jquery?

    - by PD24
    I have code code here: //Check current if (parseInt($("#Quantity").val()) < 25) { // If it is less than 25 then set it to 25 $("#Quantity").attr("value", "25"); } It checks if the quantity box has less than 25 and if it is, adds 25 to the box. The problem is on a particular product i need to check IF my pages contains: <span class="ProductNameText">This is product ABC</span> This is a work around because the customer only has 2 products which dont require 25 quantity. Ideally i would want to check if a page contained Kit Option form fields and then add 25 to the box. Any ideas on how to check for a span and then update the quantity. But the quantity shouldnt be forced, so if the user wants 6 items they should be able to add that figure.

  • Using jQuery to make a group of images appear in order.

    - by Sean Johnson
    I have a page that shows a bunch of thumbnails (around 30), and the client is wanting them to appear one by one, in order, going from left to right on the page. This is what I've tried: var start_opacity = 500; $j('.grid-photo').each(function(i) { start_opacity = start_opacity + 500; setTimeout(function() { $j(i).animate({opacity: 1}, 4000); }, start_opacity); }); It doesn't seem to know what i is referencing. Any thoughts?

  • jQuery .next() and .prev() not working as they should!

    - by Luca Matteis
    I want to get the .next() and .prev() sibling of an HTML element without excluding TextNodes. I basically need to understand if an element is directly sorrounded by <br> HTML elements. This would return true: <br> <div></div> <br> This would return false: <br> Some text <div></div> <br> BUT this needs to also return true: <br> <div></div> <br> The third example basically uses an empty TextNode, or blankspaces, or newlines. What's the best way to do this?
