Of all form fields, the file upload field is by far the worst when it comes to styling. Explorer Windows offers some but not many style possibilities, Mozilla. Note The answers comments below reflect the state of legacy browsers in 2009. Now you can actually set the value of the file input element dynamically. Picup Home Scratchpad Demo Design Patterns Best Practices Forum White Label Picup iOS App Overview Upload Files with Web Forms. Picup is an iOS Application. Almost all of the text content used by the wizard forms, prompts, warnings etc. Interactive elements that cannot be created by normal wiki text lt form elements, buttons, input text fields, dropdowns boxes etc. Javascript when the page loads.

To activate the Javascript, the wikipage must be loaded with a with. JS parameter. The Javascript code has been tested with the Firefox 1. It makes some use of the j. Query library, which is commonly used in Wikipedia scripts. Data used during the input and upload process are stored in a Javascript object named window. A representation of the input data present at any given time during the input process is cached in window. The most important functions of the script are fuw. GlobalThe constructor function of the global window. It creates the interactive form elements buttons, text fields etc. Update. OptionsThe on. Change event handler shared by most of the input elements. It collects the input from all currently active input fields, updates the cached contents of the window. It also shows and hides various warning messages in response to the result of previous validation routines stored in window. InputCalled at the end of each fuw. Update. Options, this function determines whether the current state of input data is complete and sufficient for uploading. The fuw. Update. Options function will enable or disable the submit button in response to this validation. Possible alternative keep the submit button always enabled and run validate. Input only when its clicked, showing a warning message if false. Which is more user friendlyfuw. InputThis function collects the input data from the window. Fields from them, representing the strings that are to be written into the fields of the description template. OutputCalled immediately after collect. Input, before uploading. This function assembles the code of the actual description page from the window. Fields object and the license tags, and prepares it for upload, either in local upload mode or in Commons upload mode. For local upload, it writes the resulting values into the hidden lt input typehidden elements of the Target. Form, from where they are submitted to the API. In Commons mode, the description wikitext is assembled into a parameter string to be appended to the URL for the Commons Special Upload page, pre loading the value into the standard Commons upload form. In the current testing version, this function is also called at the end of each fuw. Update. Options call, in order to maintain a constant preview of the output for testing purposes. In the final version, it will be sufficient to have it called only once, from the on. Click event of the submit button after validate. Input has returned true. Server interaction. The questionnaire page currently contains three separate lt form elements. The first, lt form idfuw. Target. Form, is the one that is actually used for uploading. The only overt element contained in it is the file selection box. All other upload parameters are present in the form of lt input typehidden elements, whose values are filled in prior to uploading by the fuw. Input function. The upload is done via a standard form. Free Pc Oscilloscope Software Download. The APIs return message is diverted into a hidden lt iframe element, whose on. Load event then triggers the function that displays the success message and hides the main questionnaire thus faking an asynchronous AJAX call this is necessary because a normal AJAX call cannot access file upload data. The second lt form element, lt form idfuw. Script. Form, contains all the other visible controls of the input questionnaire. In the testing version, there is a third lt form element, lt form idfuw. Test. Form, which contains the preview fields at the bottom of the page. Apart from the main upload action, the script sends additional server requests in the following situations. All of these are submitted via asynchronous AJAX requests to the api. Query ajax wrapper. On loading, the script retrieves the current users edit count and the edit summaries of the latest 3. The edit summaries are then scanned for signs of image related warnings, such as those left by Image. Tagging. Bot. From this information, the script attempts to make a rough estimation of the users experience level. This information is not currently used in practice, but may be used in future to choose between different versions of some of the instructions see below. When the user enters the intended Wikipedia filename, the script retrieves image information to determine whether a file of this name already exists, either locally or on Commons, in order to prevent the user from unintentionally overwriting a file. For non free files, when the user enters the intended article name, the script retrieves page information to determine whether that page exists, whether it is a disambiguation page, or whether it is a redirect in which case it will automatically correct it to the redirect target. This is done to enforce WP NFCC1. After a successful upload, the script retrieves image information about it once more. This is needed in order to get the url and size information about a thumbnail of the new image, which is then displayed in the success message. If the user has chosen to overwrite an existing file and has also added new data for the description page, the page content is sent off as a separate API edit request, because the standard upload action will not modify the textual contents of the page. The questionnaire. The questionnaire currently has twelve sub sections designed for twelve different types of files, five of them free and seven non free. Free file options. Own work contains the standard parameters license, date as well as a question about how did you make this trying to discourage uploaders from making false blanket own work claims, and an option for naming a source if the item was previously published elsewhere.

This tutorial explains how to dynamically add and remove input fields in an HTML page using Javascript. In the following article, Im going to show you how to dynamically create new HTML input fields using Javascript Document Object Model. What Ill be demonstarting below is how to use this technique to dynamically add a new file upload field to a form each time the existing file upload field is used. Also, we will be allowing users to remove the files they have previously added. Step 1 The HTML page lt form methodPOST enctypemultipartform data lt input typehidden namefilecount idfilecount value0 lt table idfilestable border0 cellpadding0 cellspacing0 lt tr idnewfilerow lt td lt input typefile namenewfile0 idnewfile0 readonlyreadonly onchangeaddnewfilethis lt td lt tr lt table lt form The HTML form would initially contain only one file upload input field. The next step would be implementing the Javascript function that dynamically append a new file upload field to the form when this one is used. Step 2 Javascript function to a add a new file upload field function addnewfilefield Get the number of files previously uploaded. Intdocument. get. Element. By. Idfilecount. Get the name of the file that has just been uploaded. Element. By. Idnewfilecount. Hide the file upload control containing the information about the picture that was just uploaded. Element. By. Idnewfilerow. Element. By. Idnewfilerow. Get a reference to the table containing the uploaded pictures. Element. By. Idfilestable Insert a new row with the file name and a delete button. Rowtable. rows. length row. Cell0 cell. 0. HTML lt input typetext disableddisabled nameinsertedfilecount valuefilename lt input typebutton namedeletecount valueDelete onclickdeleteinsertedthis Increment count of the number of files uploaded. Insert a new file upload control in the table. Rowtable. rows. length row. Cell0 cell. 0. HTML lt input typefile namenewfilecount idnewfilecount readonlyreadonly onchangeaddnewfilethis     Update the value of the file hidden input tag holding the count of files uploaded. Element. By. Idfilecount. Each time the file upload input field in the HTML form is used, this function will hide the row containing the file upload field and create a new empty file upload field to allow the user to upload another file. However, the existing file upload field has to be preserved it cannot be removed because it contains the uploaded file path and data. Instead of removing the field, we just hide it and add a new readonly text field with a Delete button next to it to allow the user to remove the uploaded file in a user friendly way. Step 3 Javascript function to delete previously uploaded files function deleteinsertedfield Get the field name. Extract the file id from the field name. Of 1, name. Of name. Of 1 Hide the row displaying the uploaded file name. Element. By. Idinsertedfileid. Get a reference to the uploaded file control. Element. By. Idnewfileid Remove the new file control. Node. remove. Childcontrol Finally, the last step would be implementing a function to delete the uploaded file when the Delete button is clicked.
