  • Preset value of HTML Forms

    - by laura
    Hi. I'm trying to preset the value of a dropdown menu and the value of a text box in an HTML form. As soon as the user taps the button in my iPhone app, it enters the webview and I was hoping to preset one of the dropdown menus and text field. How do I go about this? I want to set the dropdown to value "4" and the text field to "Giro Apps" Here's the relevant HTML form code: <select id="advSrcId" class="list" onchange="showOther($('advSrcId').options[$('advSrcId').selectedIndex].value)" name="advSrcId"> <option selected="" value="">Select</option> <option value="1">Google</option> <option value="2">Facebook</option> <option value="3">Friend Referral</option> <option value="4">Other</option> </select> <div id="otherAdvsrc" style=""> <p> Please give details here: <br/> <input class="text" type="text" value="" name="advsrc"/> <br/> </p> </div> TIA!

  • How do I insert an input's value into a separate form?

    - by ryan
    I'm making a tool for my university that allows students to create a list of classes by doing the following: Searching by course title for their course via an autocomplete input field. Adding that course to a separate form that upon being submitted creates a course list. I am trying to link the autocomplete and the course list form with an 'add to course list' button that inserts a hidden input field into the course list form which can subsequently be submitted by a 'create course list' button. My question is this: How do I take the value of the autocomplete input and insert it into the course list form without using AJAX? So far I have something like the following: <%= text_field_with_auto_complete :course, :title, :size => 40 %> <%= link_to_function "Add to Course List" do |page| page.insert_html :top, :course_list, hidden_field(:courses, :course, {:value => "$('course_title').value"}) %> <% form_for(@course_list) do |f|%> <div id="course_list">Insert selected courses here.</div> <% end %>

  • How can I detect when a file download has completed in ASP.NET?

    - by Alexis
    I have a popup window that displays "Please wait while your file is being downloaded". This popup also executes the code below to start the file download. How can I close the popup window once the file download has completed? I need some way to detect that the file download has completed so I can call self.close() to close this popup. System.Web.HttpContext.Current.Response.ClearContent(); System.Web.HttpContext.Current.Response.Clear(); System.Web.HttpContext.Current.Response.ClearHeaders(); System.Web.HttpContext.Current.Response.ContentType = fileObject.ContentType; System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", string.Concat("attachment; filename=", fileObject.FileName)); System.Web.HttpContext.Current.Response.WriteFile(fileObject.FilePath); Response.Flush(); Response.End();

  • How to access and run field events from extension js?

    - by Dan Roberts
    I have an extension that helps in submitting forms automatically for a process at work. We are running into a problem with dual select boxes where one option is selected and then that selection changes another field's options. Since setting an option selected property to true doesn't trigger the field's onchange event I am trying to do so through code. The problem I've run into is that if I try to access or run functions on the field object from the extension, I get the error Error: uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://webformsidebar/content/webformsidebar.js :: WebFormSidebar_FillProcess :: line 499" data: no] the line causing the error is... if (typeof thisField.onchange === 'function') The line right before it works just fine... thisField.options[t].selected=true; ...so I'm not sure why this is resulting in such an error. What surprises me most I guess is that checking for the existence of the function leads to an error. It feels like the problem is related to the code running in the context of the extension instead of the browser window document. If so, is there any way to call a function in the browser window context instead? Do I need to actually inject code into the page somehow? Any other ideas? Thanks

  • Changing a Variable Out of Scope?

    - by Matrym
    Is there any way to change a variable while out of scope? I know in general, you cannot, but I'm wondering if there are any tricks or overrides. For example, is there any way to make the following work: function blah(){ var a = 1 } a = 2; alert(blah());

  • Passing a var as an argument

    - by Lienau
    On a site I'm making I need to have a progress bar, I found one that suited my needs. By default it will incrementally change the color when a certain percentage is reached (0-30 red, 30-70 orange, etc). My only problem is changing them, I can set them easily with a static number such as 50, but when I try to do it dynamically (ie: 2000*.3 = 600) it fails. I don't know much js/jquery so this is especially difficult for me, if you could help that would be great. I'm pretty sure it's something really simple I'm missing. The code that Fails: var barmax = 2000; var orangeBound = Math.round(barmax * .3); var greenBound = Math.round(barmax * .7); //alert(orangeBound+":"+greenBound); $("#pb1").progressBar({ max: barmax, textFormat: 'fraction', barImage: { 0: 'images/progressbg_red.gif', orangeBound: 'images/progressbg_orange.gif', greenBound: 'images/progressbg_green.gif'} }); The code that works but I can't use because it has to be dynamic: $("#pb1").progressBar({ max: barmax, textFormat: 'fraction', barImage: { 0: 'images/progressbg_red.gif', 600: 'images/progressbg_orange.gif', 1400: 'images/progressbg_green.gif'} }); If you need to see the source, here. Thanks again!

  • Best way to detect that HTML5 <canvas> is not supported

    - by brainjam
    The standard way to deal with situations where the browser does not support the HTML5 <canvas> tag is to embed some fallback content, usually a polite version (and sometimes a less polite version) of <canvas>Your browser sucks</canvas> But the rest of the page remains the same, which may be inappropriate or misleading. I'd like some way of detecting canvas non-support so that I can present the rest of my page accordingly. What would you recommend?

  • Do any browsers yet support HTML5's checkValidity() method?

    - by James A. Rosen
    The HTML5 spec defines some very interesting validation components, including pattern (for validating against a Regexp) and required (for marking a field as required). As best I can tell, however, no browser yet actually does any validation based on these attributes. I found a comparison of HTML5 support across engines, but there is no information about validation there. In the browsers I've tried (Firefox 3.5.8 and Safari 4.0.4), no object has a checkValidity() method, so I can't run the validations even though I can define them. Is there any support for this feature out there so I can experiment?

  • disallow selection inside an input element

    - by mkoryak
    I am looking to do the following Disallow text selection inside of an input element Do not show the cursor carrot inside of an input i cannot simply blur the input on click, focus must remain in the input. There is probably a way to do this in just IE, i would of course rather have a cross browser solution but ill settle for IE (or FF) only solution. Here is a demo page where you can see why i might need this functionality: http://programmingdrunk.com/current-projects/dropdownReplacement/ if you click on the dropdowns in the first row on page, you will see the carrot inside the dropdown which looks funny. (this wont happen in chrome, but will in FF or IE)

  • How can I get jQuery UI's Draggable and Sortable functions to work on the iPhone?

    - by Damovisa
    I have a page that uses JQuery UI; in particular the Sortable interaction. The page works fine for desktop web browsers with mice, however I can't get the drag-drop functionality to work on Mobile Safari on the iPhone. Any dragging action simply scrolls the page. The functionality on my page is extremely similar to the Sortable Empty-Lists demo on the JQuery UI site. This page also doesn't work on the iPhone. Is there any way to get the drag-drop functions working on the iPhone?

  • How to create an "endless" scrolling slideshow?

    - by Andrew
    I know a good bit of JS and I'm familiar with jQuery, and I'm trying to create an "endless" slideshow (like the one on http://thisismedium.com/), where the images scroll -- one right behind the other -- and when it reaches the end it loops. I don't really know how to start, so I was hoping someone could point me in the right direction. I created a slideshow before that automatically switched images and let you click Next and Previous, but I'm stuck here. =/.

  • Chrome Extension: How to display tab objects?

    - by Jalleluhah
    I am in the process of designing an extension for Google Chrome that helps to organize tabs (I know, there are many that already exist; that doesn't matter). I wish to open a popup window that will display tabs as objects (i.e., in the same way that it is displayed in the tab bar at the top of the browser). One way of doing this would be to pull various details (ID, Title, URL, etc.) from each tab, create a class and make instantiations of it upon the opening of each tab using these data, but this seems rather convoluted considering that what I want is sitting right there in the tab bar. Is there any simpler way to achieve this? In addition, I have seen several apps that utilize page previews. Is there something in the API that allows direct access to these?

  • Binding jQuery UI plugin after $.load

    - by TomWilsonFL
    I have a function that attaches the jQuery UI DatePicker (with my options) to a passed jQuery object: function bindDatepicker($obj) { if ($obj == null) $obj = $("input.date"); $obj.datepicker( { appendText: '(yyyy-mm-dd)', autoSize: true, changeMonth: true, changeYear: true, closeText: 'Done', dateFormat: 'yy-mm-dd', defaultDate: '+1m', minDate: +1, numberOfMonths: 2 } ); } I call this at the beginning of every page to bind it to input elements: $(function() { bindDatepicker($("input.date")); }); This works fine. My problem comes in when I load form elements using $.load(). I cannot attach the DatePicker to any of the loaded elements. For example: $("#id").load("urlToLoad", function() { bindDatepicker($("input.date")); }); Loads the form elements into a div just fine, but will not attach the DatePicker. Why is this? I am stumped. :( Thanks, Tom
