I was asked an interesting question today: what is the best design pattern for form validation? This got me thinking. Form validation, on a theoretical level, is pretty simple, you: listen for events from the form, pass inputted data from the form through some validation functions, then react accordingly. I haven't really thought about design patterns on such a macro level. This does seem like a pretty standard mvc setup when I think about it, but is there a better option? Some pattern I haven't though of or heard about?
I need a html Form to accept user's input, and before the user clicks the button "submit", the user also has to select one more option (a Radio Button) to call different JSPs depending upon the user's selection.
For example, if the user selects Radio Button 1, the Submit operation will call X.jsp; if the user selects Radio Button 2, the Submit operation will call Y.jsp and so on.
I need to search and replace patterns in web pages, but I can't find a way even after reading the ad hoc chapter in New Rider's "Inside JavaScript".
Here's what I want to do:
function filter() { var items = new Array("John", "Jane");
for (x = 0; x < items.length; x++) { //Doesn't work pattern = '/' + items[x] + '/' //Doesn't work either document.body = document.body.replace(pattern,"IGNORED"); }
ie., create an array of items to look for in the BODY section of the page, and if any item exists, replace the item with IGNORED.
I want to create a horizontal stacked bar chart that it will support zoom in/out and mouse over events. I also want some times instead of colors to be able to use patterns. For the first part it seems that only dojo can produce those charts. In addition, i haven't seen any javascript library to support patterns in any kind of chart.
How do you count patterns in record fields and create an array of it?For example:Searching in (using my example below) currently gives me multiple outputs of
0 0 (**in** seen at index 0 of book 0 title record) 0 13 (**in** seen at index 13 of book 0 title record) 1 19 (**in** seen at index 0 of book 1 title record)
I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.
I am trying to display validation error messages when form validation fails. Currently it does display the error messages but then disappears straight away. How can I stop the page from refreshing when validation fails? I have return false in my code when validation fails but still having same problem. Currently I have only done the validation for the full name only. The error msg is showed in:
This is in regards to Jrn Zaefferer's plug in.How do you customize input validation so that I can remove foullanguage?So that first name or last name doesn't have "fck you" or something
I'm using the Validation plugin for JQuery and was wondering if there was a function to submit the form without causing it to validate the form. I have a table with a list of radio-buttons and above that is a drop down list of states. The drop down list of states is used to filter the table rows and when the selected item changes it posts-back to the server (via $("#frm").submit()). I don't want this to cause any validation to occur. Is there another function I can call besides submit(), or some other method?
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
I read a lot on how to make in Javascript programs in a OOP way. After I download many third-party library (like YUI, prototype ecc.) and I have seen that almost all the function (class) are designed like literal object notation and not in a normal way like I learned ... now I'm confusing on how to design my classes... I came to a Java/C++ experience ...
It seems that with object literal notation we cannot make all the OOP constructs that we can make with normal Javacript class creation constructs... so why is it so largely used?
I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it.
The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem.
I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs.
<problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.
I am having a tough time coming up with a good design for a webpage. The following is a brief description of what i am trying to achieve. The requirement is for an insurance company and the goal is to gather insurance policy information to give its users a quote.
The user can add/edit/delete policies before submitting it and going to the next step.
Each Policy can have 1 Amount (required) and 0 to 3 fees associated with it.
At a given time a user can add a maximum of 8 rows.where each amount/fee is considered a row. So if user enters all rows (1 Amount and 3 Fees) for the policies then the user can add a maximum of 2 ploicies. On the other hand if the user wants to enter just the Amount then he can go to 8 policies. I have developed the webpage for this requirement using layers but there I had to write a lot of code for that. I am sure there is a better way to handle such a situation and that is what i am looking for.
I am unable to include the code with this post due to its size. If anyone is interested in looking at the code i can email it to them.
I was writing my classes in an old fashion until today when I came across a new design pattern. Javascript is not an established OOP like C++ or Java. It doesn't have any easy way to create classes and to make private/public methods or properties as well as class-constructor. But it could be done in many ways.
My old way of OO design in Javascript was like following:
Code:
Those who were trying to write constructor and access public vars from private or vice versa, you would have probably faced some minor difficulties. But it was doable.
Now, the challenge is how can we make things cleaner and better. Here's the procedure I came up with:
How to design a vertical progressbar. using jquery and css .. Also it must be having a flow like from up to down and vice versa. also the progress must be animated..
I have a search form all over my pages and I have a page for the results. What I wanted to do is when I clicked the button, I want message on the page where the results are. the message would would be "Results related for (text that inputted on the search form)" and I also wanted to put an image background for that.
I'm having trouble changing the font color of my labels ONLY when I stop the form from submitting due to blank fields. I'm not sure whether if just changing my CSS will achieve what I want, or am I going to have to add somethig to my if else statement, or both? I would think I would need to change CSS to :
label.onfocus { color:red; }
but a little confused on what else.

I have a working contact form with 3 of the fields requiring validation and they work well. I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them. My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag.
<script type="text/JavaScript"> <!-- function MM_findObj(n, d) { //v4.01 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
I currently have a form named "survey". I found here a JavaScript to validate my form.
I am having serious issues with this script, either it won't execute at all (the form doesn't work, as well as the validation) or the form submits without validating the form.
I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes.
I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return.
I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. just for testing purposes I've put return false on everything so it displays a message when everythings ok.[code]
I need save to my html page id path adress like id="#videos/fashion/test.txt" but if I want find this line like $("div").find("#videos/fashion/test.txt") it doesn't find it. I think it for the slashes. What is the best way to save into html page value and not to be seen on design view?
