how to submit html elements text, hidden etc., along with file element?
While using multipart for file element, the other elements are not read, like request.getParameter("") gives me null for other text/hidden elements...
please help me in this with the solution...
Thanks.

<form enctype="multipart/form-data"... definitely does what you want.
Ensure that your other elements are inside the same form as your file input, and ensure that you have set the name attribute on all input elements you want to submit.

Is there any way to allow a link/anchor within an input field so that whatever text is in the field is ALSO clickable and actionable?
This is unfortunately not possible in HTML 4 or below. Even with HTML5 which has several new INPUT TYPEs, including URL, it only does validation and has some other useful functions, but won't give you want you want.
You might look for some jQuery plugins that can help you do this, most use the same principals behind Rich Text or other online/web-based HTML WYSIWYG editors. I've had trouble locating them myself.
These 3 situations (that I can think of right now) are pretty much what you will face natively with HTML4 or below, as text in an actual HTML4 INPUT textbox is pure text. It is not html and therefore NOT clickable. Here are some variations:
The INPUT tag's VALUE attribute, also referenced as the corresponding DOM object's "value" property (which is basically what you've been doing, and the most you can hope for, if you decide that you MUST have the text that's ACTUALLY inside the textbox (because the text inside the textbox is the VALUE attribute, as I have it with "http://yahoo.com" in this example):
<input id="myTxtbox" type="text" value="http://yahoo.com">
where the INPUT's VALUE = "http://yahoo.com", which you can retrieve with:
in pure javascript:
document.getElementById("myTxtbox").value
in jQuery:
$("myTxtBox").val()
When your link/url is the text in between the <INPUT> and </INPUT>, i.e. the text/innerText of the textbox. This is useless for your question/scenario since it's not clickable, and more importantly NOT INSIDE the textbox. However, someone might want to use this to retrieve any text that you may be using as a label (if you're not using the <label> tag itself already that is):
<input id="myTxtbox" type="text">
http://yahoo.com
</input>
The textbox's text/innerText is NOT an attribute here, only a DOM object property, but can still be retrieved:
pure javascript:
document.getElementById("myTxtbox").innerText
jQuery:
$("myTxtBox").text() -- you would use this to capure any text that you may be using as a label (if you're not using the tag).
The result being: http://yahoo.com
When your link/url is the form of an ANCHOR (<A>) with an HREF to your url (and visible link text) in between the <INPUT> and </INPUT>, i.e. the innerHTML of the textbox. This is getting a bit closer to what you want, as the link will appear as, and function as an actual link. However, it will NOT be inside of the textbox. It will be along side it as in example #2. Again, as stated in example #1, you CANNOT have actual working HTML, and therefore a working 'link' inside of a textbox:
<input id="myTxtbox" type="text">
<a href="http://yahoo.com">
http://yahoo.com
</a>
</input>
Once again, similarly to example #2, the textbox's innerHTML is NOT an attribute here, only a DOM object property, but can still be retrieved:
pure javascript:
document.getElementById("myTxtbox").innerHTML
jQuery:
$("myTxtBox").html()
The result being: http://yahoo.com
So I have this textarea in my website. By default, it has something like this as its contents:
Name : Sample Value
Age : Sample Value
Location : Sample Value
It is editable before the user hits the button and inserts it into the database, although I am not using a rich text editor since it's nothing but a simple text.
Since basic HTML codes are not browser readable inside the textarea tag, I used
to separate lines.
Now my problem is that I am not able to include the HTML code when I'm reading the value of the textarea tag in the server side.
Thus, the value inserted to the database is not HTML formatted as well, and when it is once again fetched into a web browser, it has no format at all.
What alternatives do I have? Thanks.
Not possible using textarea, use contenteditable DIV instead.
<div contenteditable="true"></div>
You can use getters and setter as shown below:
//Get content
var contents = document.getElementById("divId").innerHTML;
//Set content
document.getElementById("divId").innerHTML = contents
Here is the browser support for this approach.
Why don't you use JQuery and do this $(textarea).val() to get the value of the textarea as a string and use it server side. you might have to consider using Ajax to make a call to the server side method you want to pass the Html data.
The answer is very simple.
Use contenteditable DIVs instead of TextBox and TextArea.
But remember to add contenteditable="false" to all your inner HTML tags.
This worked for me.
How can I get HTML to work in the value of the input field ? If you include HTML in the value, it appears as pure text. Is there a way to do something like this?
<input type='text' value='<b>tekst</b>'></input>
So the the output is:
tekst
instead of
<b>tekst</b>
I think that was bad example... I want every appropriate HTML tag to work. If i want to include an image, the image appears in the input, if i want to add a tag ... the text should appear as a link linked.
I'm not sure from your question whether you are trying to make the value contain HTML, or whether you want to apply HTML to something inside the input.
If you want to be able to set the value to some HTML, like <input value="<b>Some HTML</b>"> where the value will actually show the HTML, you need to encode the HTML brackets like <input value="<b>Some text<b/>">. There are functions available to do this for you automatically in most scripting languages (e.g. htmlentities() in PHP).
If you want to apply HTML to the input value, short answer is... you can't. If you want formatting on there, you could use the contentEditable attribute in HTML5 which lets you just edit-in-place (think Flickr headers).
If you just want a standard input field to be styled, you can just use CSS like the other answers suggested.
You have to encode all the HTML you want in the value and paste it in the input value.
If you encode this:
"http://sansoftmax.blogspot.com/"
It will look like this:
"http://sansoftmax.blogspot.com/"
In input:
value=""http://sansoftmax.blogspot.com/""
Online Html Encoder/Decoder
You can try to decode you entities from your postvalue.
In PHP you can do this with html_entity_decode();
I don't think you can put HTML inside a text field and have it interpreted as HTML instead of as text in the field.
To accomplish what you want you'll have to use CSS. An in-line example to bold the text as you cited in your example:
<input type="text" style="font-weight: bold;" value="tekst" />
Try CSS:
input[type=text] {
font-weight: bold;
}
I have an HTML form with radio buttons, check boxes, text fields and drop down lists.
Since I want user to fill everything in my form, none of the radio buttons and check boxes are checked and the text fields are empty.
I would like to write a CSS file that will fill the form with answers (I don't want to change my HTML file).
Is this possible ?
I would appreciate an example or any other idea ?
Thanks !
No, it isn't possible. CSS is for style, not markup, and changing the contents of an input field requires modification of the markup.
It sounds like you might want to consider JavaScript, which can be used to alter the contents of any element, including form elements.
Javascript is your best bet. If you want to fill in -sample- answers, however, like 'First Name' in the text area what would be labelled "First Name: " you can do something like <input type='text' value='First Name' name='emailForm'> and the value attribute will be filled in when the page loads.
You can use jQuery to accomplish what you want quite easily, using CSS-style syntax.
Here's a sample form:
<form ...>
<input name="firstName" />
<input name="lastName" />
</form>
And corresponding jQuery/JavaScript:
$(function () {
$("input[name=firstName]").val("John");
$("input[name=lastName]").val("Doe");
});
Should be easy enough to extend to a larger and more complex form. You can easily use classes or ids on the elements and in the jQuery selectors, as well.
CSS is for designing and styling the webpage. Although its capabilities have been exploited to pull of many tricks it is not a fix-all solution. What you need to do is pull the data you need to fill and put it in your fields.
You can do this two ways:
Use a server side language like PHP/ASP.Net to pre-fill this information.
Use Javascript/Jquery/MooTools or some other framework to fill it on the client-side, picking up the data from the server.
If the information is static then it is very easy, because you can just put this info as a part of the HTML content itself.
If this answer doesn't work for you, add more information to your question.
I have a form within another form:
<form id="a">
<form id="b">
<input type="submit">
When the submit button is clicked, it seems that the outer form is submitted.
Is there a way to target which form is submitted?
No, nested forms aren't supported:
There can be several forms in a single document, but the FORM element can't be nested.
-- http://www.w3.org/MarkUp/html3/forms.html
The HTML DTD specifically forbids a form element from containing another form element:
<!ELEMENT FORM - - (%block;|SCRIPT)+ -(FORM) -- interactive form -->
http://www.w3.org/TR/html401/interact/forms.html#edef-FORM
Like others have said...nested forms aren't allowed.
However, that doesn't mean some browsers won't do something with such. In the example that you have presented, the browser appears to be ignoring the second <form> tag in a similar fashion to how an unknown tag (i.e. <notAValidTag>) is also ignored. Since JavaScript also doesn't allow for embedded form collections, the best way to ensure that FormB's information is submitted is to make it no longer a nested form. This will break up your markup and UI into more distinct sections which may be beneficial from a UX perspective as well.
i think this is not allowed by the html standard.
In HTML 5, yes. Each input element can have a "form" attribute signalling which form it belongs to. However, it is still invalid to nest forms in HTML and HTML parsers won't allow this to happen.
However, it is possible to construct nested forms via JavaScript. In the absence of the form attribute, the rules for determining which form an input belongs to are quite complex, but they are described in full with an example at http://www.whatwg.org/specs/web-apps/current-work/multipage/association-of-controls-and-forms.html#association-of-controls-and-forms
Specifically, step 5 of Reset the Form Owner says:
Otherwise, if element has an ancestor form element, then associate element with the nearest such ancestor form element.
Clearly, "nearest" would not need to be said if form nesting was impossible.
Then step 4 explains how the required form can be targeted, by associating the submit button to the required form though the "form" attribute on the button.
If element is listed, has a form content attribute, and is connected, then:
If the first element in element's tree, in tree order, to have an ID that is identical to element's form content attribute's value, is a form element, then associate the element with that form element.
