JQuery :: How To Validate Web Form Before Submitting

Feb 1, 2010

I have a asp.net web form that I need to validate before submitting. I've tried the AJAX Control Toolkit but I was having problem with multiple ValidationSummary control conflict. So, my next option I can think of is to use jQuery. First of, how do I test to see if a textbox is blank or not? If blank, output a message to a asp.net Label control on the page and stop the web form submission. Second, if the validation succeeds, proceeds to submitting the web form.

JQuery :: Submitting Form Without Submit Button - Validate - Lightbox ?

Sep 15, 2010

I am pretty comfortable with jQuery and the validation plugin as well.

I am having an issue where:

User clicks a button it opens a lightbox (I am using Fancybox) - a form appears inside the modal. The data is submitted via AJAX and I am trying to validate the form before the form within the lightbox is submitted.

My button with the click handler right now does a GET to a server to send the data. Along with some other JavaScript. What is the best way for me to validate my form within a lightbox, and submit after it validates. Sending AJAX.

Validate File Size Before Uploading To Server

Jun 14, 2011

In JSP / HTML, I want to restrict the size of file being uploaded.

If the size of file more than a specific size say 5MB, i want to give mesage to the user. I don't want to wait till the file gets uploaded to server and then validate the file size. I need client side validation. Can it be done using scripting language or any other way?

I need a solution for this in Internet Explorer. There is already a solution I got using ActiveX control:

But ActiveX controls not allowed in our application. Is there any alternative way for this?

JQuery :: Get Form File Field Binary Contents Without Submitting?

Sep 19, 2010

I'm using a form on a page as a vessel for data, rather than to actually submit it. The reason is that the form is submitted to a service at www.rdbhost.com with it's special JS API, so I extract the data from the form manually and then feed the data to the methods from the provided library.

One of the field is a file. Calling ``.val()`` on it simply gives me the file name, but I need the contents.I've looked around, and found a few plugins that would actually send the file, but that's not what I want.

Return Function Without Submitting Form?

Nov 14, 2011

The following form works great except I want the form field difference to populate after onFocus instead of when I submit the form. I have tried <input type="text" id="difference" NAME="difference" SIZE="12" onFocus="return dateDiff(this);" > but nothing happens. After I type in the to times I should click on the difference field and it should populate like it would if I submitted the form. Is this possible?

<form onSubmit="return dateDiff(this);">
<INPUT TYPE="text" id="firsttime" NAME="firsttime" VALUE="" SIZE="12" maxlength="5"><span class="style1"> hrs</span>
<INPUT TYPE="text" id="secondtime" NAME="secondtime" VALUE="" SIZE="12" maxlength="5"><span class="style1"> hrs</span>

Submit Form, Validate Form, Set Cookie, Send Email, Download File

Jul 23, 2005

I have a form built and on the onclick event I validate all of the
fields and then if the form is ok, on the submit event I run a
javascript function to set a cookie and download a file from the
current window.

I have a cgi script provided by my web host to send the contents of the
form through email but they only show me how to use the cgi script to
send email through the submit event of the form.

ie. <form name="downloadform" method="post"
action="/cgi-bin/cgiemail/mailtemp.txt" onSubmit="return
Validate(this)">

Can I utilize the cgi script/link from my javascript function and still
send the contents of the form through the cgi email??

JQuery: Validate Certain Fields With A Function In A Multipart Form

Apr 19, 2010

I have a simplified version below of a multipart form. There are two steps and two tabs. I want the user to enter their username and email address and click 'Next' which will validate to make sure those fields are filled in, then activate and advance to tab #2 (Step #2) of the form, where they enter their credit card information.

I am having difficulty because username, email and credit card are all in the same form and I need to only validate certain fields on each step of the form. I was thinking I could make a function when the 'Next' button was hit that would validate the first two fields?

Here is what I have so far. I have a 'Next' button which activates and advances the tab to Step #2, but I need to work some form of validation into it before it advances. At the bottom of the page I have a 'Submit' button which is just so you can see that the validation is working if the form is submitted. I just want the 'Next' button to activate a function to only validate the fields on Step #1 (username/email).

Give it a look:[url]

JQuery :: Get File Path & Size Of The File To Upload In Internet Explorer 7?

Sep 1, 2011

I'm trying to put in place a file upload validation check. So at the client-side, the User selects a file. Before uploading, at the GUI, if the file exceeds an imposed limit, it will prompt the User that it exceeds the permitted size for upload.

And if it is within the permitted size, the full file path of the file to be uploaded will then be obtained and then used for the actual upload to the Server.

My program is built on EXTJS and Java, running using Tomcat. Browser restricted to Internet Explorer 7 only.

Cannot Validate Form Function ?

Dec 9, 2009

I have a form that submits a POST request when data is submitted. A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine.

However, I am suck trying to validate the form on the client side with a JavaScript function before the form is submitted.

Here is my index.jps:

Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given.

Am I correct in calling the function onClick?

The validation essentially needs to be so that:

- Student field contains a string

- Score1, Score2, Score3 and Score 4 contain a number between 0 and 100

Limit File Size Or Request Size

May 27, 2010

I developed a web application and it is working fine, except for one issue. The application includes uploading files from a JSP to my servlet, and the issue is that i would like to have a limit for the uploaded files on the client side (before actually uploading it).

I investigated alot and found some ways like changing my JSPs to PHPs, which is not feasable for my application. I would also like to add that using the Flash component ("<object>") for uploading is not feasable also at this time. Using ActiveX does not work also (for some security issues in javascript, it can not access the system information, also ActiveX works only on IE).

I would like to add that I have my application running on Oracle application Server, JSPs for displaying the forms, MultiPart Java API for getting the form input values and files to my servlet and everything is developed in JAVA.

Either by limiting the file size or the limiting the whole request size sent to the servlet.

JQuery :: Accessing Value In Ajax Form Without Submitting The Form?

Jun 2, 2009

I have a form. Upon submit, the data is sent to the server. Under certain conditions, the form is replaced via ajax with a set of radio buttons that offer the user a a choice.I need to access the radio buttons before I submit the form again.Normally I could just access the buttons with getelementbyid but it is not available, presumably because they were generated via ajax.I could submit the form just to access the radio buttons and then submit it again, but I'd like to avoid that.

How To Check The Input File Object File Size On Client Side?

Dec 20, 2004

I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:

1. Malicious user trying to collapse the website sending big files.

2. Users that have not seen the warning “Maximum size: 100 KB&#65533; for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.&#65533; And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!


I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:

“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
