JQuery :: Validation For Dynamic Field To Check The File Extension?
Aug 25, 2011
I am using jquery.validate.js for my validation. I need to validate some dynamic input fields. By using class now I am able to validate that. Here my problem is to validate for the file extension.
For static files I use as
file: {
required:true,
accept: "png|jpg",
},
How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.
is there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.
I would need javascript code to check extension of uploaded file. File upload in not mandatory, but I need script to check extension and allow only JPG, BMP, PGN and other Image files.
I have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.
I have some problems with validating form in javascript.
I have a following HTML code:
What I want in validation is to check all the field in form (check for required fields etc). I want to show user error message in div tag with id='poruka'.
Part of code of function ValidirajFormu:
So, validation works OK, but message is not written in div tag. Only if all fields are correct, form is submited, but there are no error message.
Is there a way by which I can validate in javascript whether the file I'm trying to upload is an existant one(i.e., one which is present in my local folder).
this is a code I recently found that enables dynamic creation of a file upload field within a form using javascript. I am new to all of this and have some previous actionscript 3.0 experience. Is there an IF statement that I can place inside the 'addLoadEvent' function that can limit the amount of fields created?
Code: function fileFields() { var x = document.getElementById('imageUpload');
I have a folder "A" with 10 files, all with .txt extensions in it. I want a java script to open all the 10 files in the folder "A" and change the extensions to .js and save it in a folder "B".
JQuery and I have a function which adds an image to a link depending on the file type.
How to write a statement that says....if there is no file extension - leave the default styling, if not add file extension. At the moment I have dots and images..see here [url]
I've been doing some research on url names. The problem is, I need this code to return like say "index.php", it would return "index". But idk where I went wrong..
The code: <script> var sPage; var sPath = window.location.pathname; //var sPage = sPath.substring(sPath.lastIndexOf('\') + 1);
I allow people to upload images onto my web server. I want to verify each image is less than 50Kb and is an image type, this is what I came up with Verifying the files extension Code:
I have seen many Javascripts on Internet that checks the extension of the file before uploading. But all these scripts checks the extension when the Submit button is pressed. I want to check the file extension as soon as the file is selected. The script should delete the selected file from the type=file box and display an error message (when a file with the wrong extension is selected).
I have a flash player pulling videos from a folder and Im using the Javascript below to display the name of the file that is currently playing. What I would like to do is remove the file extension from the filename when it is displayed.
Currently displayed: Now Playing: Michael Jackson Thriller.mp4
Fixed display: Now Playing: Michael Jackson Thriller
The mounds of RegExp data will take me days to sift through can someone help me create a regular expression to find a file extension? (all characters after a period) I have already gotten this far: .+. to find everything before and including the period; and I was hoping to integrate the caret to say everything but .+. But I just can't get it to work.
Note: I will be writing a file to the server with JScript ASP. The file name will be passed to the script that writes the file, and I want to make sure that in addition to removing any possible code from the line being written, that I also prevent an executable file from being created. I will be searching for certain extensions and returning if anything else is found.
I am kinda new to java scripting and here is what i am trying to do. I have a folder "A" with 10 files, all with .txt extensions in it. I want a java script to open all the 10 files in the folder "A" and change the extensions to .js and save it in a folder "B".
[How to fetch filename with extension from file path? The file path is like this.(E:/videos/India.avi). I want to fetch only India.avi from file path.how to do it in javascript?/]
I'm using the validation plugin available here and seem to be encountering trouble in IE7. The validation is not occuring and my forms submit. Not what I want.The functions below are working fine in FF3, Opera 9.0, Chrome, & Safari.I'm going to guess this is a result of some misplaced character or ...??? Maybe a second set of eyes will spot the error.
I will like to know if there is anyway to view all the rules that I have currently in the Jquery validation plugin. Currently, I am trying to add in rules dynamically through the rules(add) function after adding some dynamic fields through the user inputs. the rules are added in this manner.
I need to validate two forms containing multiple input fields but want just one error message if any of the fields are left blank, the page is required to submit the users details (registration form). Also if any of these fields are left blank i don't want to be able to go to the next page on clicking the submit button
The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
