AKA, if I have two fields (one radio button group and one textarea that only appears if the "other" radio button is pressed) how would I make it so the input from the text area overrides the "other" button having it's value placed in the mailto?
E.g., I want this to happen:
field1=text from text area
NOT this:
field1=other
field2=text from text area
Could I set the value of the "other" radio button in field1 to the text coming from the text area?
Alternatively, could I do anything to prevent a certain field from appearing in the mailto fields?
In future, please ensure you present SO with a code issue, not a general question or request. However, you would use a JQuery change handler, like so:
$('#mastertextboxid').on('input', function(){ //executes every time master's text is updated
$('#slavetextboxid').value($('#mastertextboxid').text()); //updates the values
})
This will overwrite any text in the slave textbox when the master textbox is changed, but the User will still be able to input into the slave textbox. It's known as One way data binding.

I have an input field of type = "text". At the time of entering the details into the input, I can enter a long input. The value is getting stored appropriately in DB as well. After clicking on a submit button, I am disabling the field.
So input is still visible but with only the value (noneditable). The problem arises here as only the length of text box input is being displayed.
Is there any way in which the entire input will be displayed?
One way to do this is instead of disabling the input box, you just remove the onChange event on the inout field and style the text to look like its disabled. if onChange event is something like this:
onChange={() => ()}
It won't be able to change the value of the input field, as it has an anonymous function.
That's one of way of doing it.
I have a custom Visual Force page that on load has a name field that is supposed to have {Auto} printed inside the input text box that the user can delete or leave or not. I have been using a html-placeholder however the text just disappears and is gray.
My VF inputfield:
<apex:inputfield required="true"
value="{!EventPackageRevenueBreakdown__c.Name}" html-placeholder="{!Auto}"></apex:inputfield>
What it looks like with that code:
What I need it to look like (notice the cursor is after the closing scope)
Thanks in advance I'm still very new to this!
I suggest you to set Name field in controller with '{Auto}' value.
The placeholder attribute will disappear when there is a value in the field, what you want is to actually set the VALUE of the field to {Auto}.
Try this:
If you want it to automatically clear the field if a user clicks into it, you could add some javascript to handle that.
I have an HTML form with a check box linked to a text input. The check box enables/disables and clears the text input (don't need to save the text value if unchecked).
Should I save this information in 2 db columns or one?
With one I figured I could use NULL if the check box is unchecked. I'm not sure what the best option is.
Thank you
You are right, field type should be text with NULL option.
null means checkbox was checked
empty means no text was entered
I have a clarification,probably a simple one..Once we enter some values in input type for text,date ect ,the previous values which we entered is stored.(probably a cookie) until we give autocomplete off..
Why this happens only in textboxes and not in text area by default?
This is something which does not exist in browsers.
If you wish to have it, you can use the jQueryUI autocomplete widget on textareas.

I have a table that lists items. I have a form tag that surrounds this table. In this table I have ADD buttons that adds new rows to the database. I have EDIT buttons that edits a row as well. The form posts to the same action on the controller.
Now I need to add a filter row on the first which means I need to add a Filter button to submit the form with the filter parameters. Since this is still inside the main form, I now have the following problem: When I click the Filter button, the inputs that are used for the ADD button are being validated before anything gets posted. How can I prevent the validation from occurring when the user clicks the Filter button?
Make sure the Filter button is of type "button" not "submit" and do filter using ajax
As i see it, the easy way would be to fire the submit via js with:
.submit();
The other way would be to disable validation on that form with this:
$('#form').validate({
onsubmit : false
});
or
$('#form').unbind('submit')
I have one suggestion. Name Add button inputs differently and add row using javascript/ajax. When posting, Add button inputs will not be validated because they have different names
