I only use forms as input and output to javascripts. Many times I use
innerhtml to write to a <div> for output. I don't know of an
alternative for input.
I sometimes have problems if I use method="post" and just leave it off.
The browser tried to reload the page after the script ran. Sometimes I
am able to even leave off <form> and </form>. Could someone explain
when form and method are actually needed?
I responded in comp.lang.javascript to "Adding to fields with
onchange". I had to leave "method=" out to get it to work without
trying to reload the page.
I have a form with a bunch of fields that, when submitted, triggers a CSV download of the requested data. What I would like to do is provide a URL for the CSV download based on the current state of the form that the user can copy and use without having to submit the form. I've written my own code to do this where everytime a field is changed my JS code loops over the fields and figures out what the URL would be if the form is submitted.
But my code is not flawless and right now it's breaking if a field has an array name (i.e. name="arrVar[]"). I'm sure I can fix it, but I'm not going to catch more complicated array naming because I can't be bothered. I'm wondering if I'm overlooking a convenient way to get the URL a form would generate on a submission without having to write a form parser myself.
I have form/select which executes a function using onchange. No problem. However, when I validate the page with a strict HTML 4.01 doctype at http://validator.w3.org, it demands either an action or a method for the form?.
If I give it an empty action <form action="" ..... it validates OK. Is this acceptable or is there a better/standards correct way?
Just wondeing if there is a way to keep from having a certain parameter sent when posting a form to another page (method=get)...
So as an example a page will post something like this from a form using "get":
http://mypage?firstElement=1&secondElement=2
How can you completely remove "secondElement=2" from the querystring... Before moving on to the posted page?
I know you can actually remove the element using removeChild in javascript, and therefore it won't show up in the querystring of the page posted to:
ochild.parentNode.removeChild(ochild);
But I was wondering if there was a way of doing it? A person can see an inputbox for example disappear for a split second before the page is posted... Is there a way of accessing the querystring itself in javascript? Or some other way then removing the element?
I have some function to fire when I click a submit button. When I do that a form does not submit anything, it just fire my function etc. Here is my code: $("#hm-submit-form").click(function () { $("#nav ul li.products").delay(200).fadeIn(); $("#nav ul li.agel-tour").delay(600).fadeIn(); $("#nav ul li.compensation").delay(1000).fadeIn(); $("#thanks-box").delay(200).fadeIn(); $("#thanks-box").delay(1500).fadeOut(); $('#target').submit(); //this I guess should submit a form
I need to make a change to a web page that has lots of JQuery things in it, it appears. Not knowing anything about the actual use of JQuery, however, while I will start looking at the doc, can someone help me with what to look for in a 4000+ line file to find out where the value is being set for the hidden field. I have been unable to identify this. There appears to be no onChange or onSubmit JavaScript call. I have been given this file with the need to figure this out right away, with a very tight timeline to make many changes, so this one item can't take the time required to start learning the whole of JQuery before I can make a change.
I'm looking for a method to use several hyperlinks to submit a form and then return the page within the link for example:
The reason for this is so that no matter which link a user navigates to the form will be submitted and no data lost.
However the above code obviously loses the POST info as the form action will be different from the a tag.
Therefore I think maybe a way of creating a variable that changes the form action to match the a link selected (as the form(s) are submitted to the same php page.
I am having trouble finding a code example that uses javascript to get values from a form submitted on a previous page using the "POST" method. I've found some examples on how to parse the query string, but unfrotunately my form on the previous page has WAY too many charcters being submitted to be able to use the "GET" method (there is some upper limit here, I think it may be 255 or some number similar).
By the way this ONLY needs to work in IE, but it is better if it works in all browsers.
This is my first post, and I'm only just learning jqury/JavaScript.
i have a form I'd like to send via POST method to a second php page, i have all the validation etc working fine, I'm struggling with the on Submit handler.. once the form is validated...
can anyone please tell/direct me how i can post this form to a php page that will do the data insertion?[code]...
Does anybody know how to turn off form actions please?
I have 2 types of users (members and non-members) using the same form action. This form has 4 buttons in total.
If the user is a member they have full access to all buttons.
If the user is a non-member they can only use 2 of the 4 buttons.
So, at the moment, when they are non-members and click on one of the members buttons, an OnClick event handler is added to the input type = "submit", which generates a new window with a document explaining to the user that they need to register.
There is no problem generating this window.
The problem is that the form specified in the form action still executes and the members page is still displayed.
So is it possible to turn off the form action in this instance so that the main page isn't refreshed/executed, or do I have to create different form actions for different users.
Surely there must be a way to prevent the form action from being triggered?
I realise I could simply not display the button for non-members, but I'd prefer to do so, as it allows them to see the features that members receive.
I have problem getting dynamic form elements values created with .append method when submitting the form with POST method in Firefox. It seems to work only on Internet Explorer.
I'm having a problem where the serialize method isn't serializing form elements that are added to the DOM after the page load. Specifically, when the user clicks on a button some elements are displayed in a dialog that are generated from my server and returned via AJAX. I'm converting from Prototype and didn't run into this problem.
I'm trying to do something, but I don't know if it's possible. Basically, I want to have a public static class method that could access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing something like
function method(param) { param.privateMethodOfClass(); }
I've done a lot research and experimentations but just can't come up with a solution... I don't even know if what I'm trying to do is possible.
Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:
function Core(){ var obj = {a : 'a', b : 'b'}; var num = 1;[code]....
//right now none of the above would work but it's more convenient than using the call alternative.
} Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision?
I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.
Is the form below a valid method of changing the id of an XHTML element, specifically the one actually being referenced? It does not seem to work for me.
function doSomething () { var obj = new Obj(); obj.foo = bar; doSomethingElse(obj); }
In function doSomethingElse I want to create the following line of DHTML
<div return true;">
What I want is for onClick to be defined to be the execution of the foo method of obj.
I tried document.writeln ("<div + obj.foo + "(); return true;'>");
What I get is the source code for bar stuck into the middle of the string. So how do I get just the name of the function bar in the string? Or ultimately, how do I get the handler to be bar in the DHTML?
While submiting the form elements, if the GET method is used in the <form>tag, the data is submitted as a query string.I think there should be restriction in size of data submitted by the browser IE. Does any body know the exact details of it?
