Is it possible to display an input form field based on the value of a select menu? Or is this something I'd have to do in javascript/jquery?
My list is pulled from the database if that changes anything.
If you want to make this happen during the form filling, yes you probably will need to use Ajax (via vanilla Javascript or jQuery), if you need to query your database as options are selected, or just CSS: http://www.coderanch.com/t/594720/HTML-CSS-JavaScript/Show-Hide-text-box-select, if you populated via database but don't need to check it again for changes.

Scenario/Context
I've got a drop down menu with two input elements underneath.
From the dropdown menu, are names of companies (with values set to the respective company id's), and another prompt to Add a new company.
If the option to Add a new company is selected from the dropdown, then the user is to fill out the 2 input field elements (i.e. company name and company email).
Otherwise, if an available company is selected from the dropdown,
then the 2 input fields (for company name and email are to be disabled).
My question
Is this possible to do without an AJAX call if I want things to happen without a page refresh?
Can anyone suggest some other alternatives??
Many thanks!
That is absolutely possible, though you'd need to use some JavaScript to make it happen and load a bit more data to the DOM on the initial page load.
For each option in your company select dropdown, add a data attribute for the name and email.
Then, watch that dropdown for the change event in JavaScript. Whenever that event is fired, if the data-company-name and data-company-email attributes are defined for the selected option, disable the input fields and populate them with those values. If those data attributes are not defined for the option (likely only for your 'Add a new company' option), then clear the values from the input fields and enable them.
I have created a page based on "Form & Report" template. So there is the Report page on which there is the create button. That create button leads to the form page which contains.
It is pretty simple. I don't know if there is a cache memory not emptying itself or if there is a setting that I have not properly set.
When I want to create a new database record, Oracle Apex behaves as if I asked it to update a record (though it still presents me with empty text fields).
Below the image of what's happening.
Create button of the Report
Buttons for edit are shown when I click the create button
Those edit buttons are shown instead of the buttons below => This means that the Apex software is behaving like I asked to edit a record not to insert a record.
Why is this happening?
You need to take a look at your create button. Is it passing a value to the form? If so, you probably don't want that. Is it clearing the cache of the form? If not, you probably want to clear it.
Also, on the form page take a look at your processes.. specifically the Automated Row Fetch (ARF) process.. what's the primary key that this process is using?
Also, take a look at the conditions for each button on your form. For the delete/save buttons you likely want a condition type of "value of item / column in expression 1 Is NOT NULL".
For your create button you would want the opposite.. "value of item /... IS NULL".
In both cases for the expression 1 you'd want to use the item that your ARF is leveraging.
#Bloomberg58 if you used the wizard that should not have anyway try to validate the create button in report page and the server-side validation of create and save button in form page
In Tableau 9.2, how can I use a filter which filters from one dashboard to another so that when I trigger it, it does not switch dashboards? I have found this answer online, yet the poster cautions that their method should only be used for V7 and not V9.
Create another action as a filter in the sheet you want to stay in and select all of the dashboards as source and target. As this is the newest action it should make you stay in the same sheet while you keep applying different filters to your data.
In the Dashboard Menu go to Actions and add a Filter,in the filter select source dashboard and select other dashboard as target.This will redirect you to different tab.
You could use a parameter along with calculated fields, or use the JavaScript API
Filter actions also change to the target sheet or dashboard, if not already in focus (as you found out)
If you are doing single selection and your list of values is relatively stable, you could use a parameter instead -- loading the initial values from your field. And then define calculated fields that access the parameter value and use those fields on filter shelves as desired.
Changing a parameter value does not change the view to a target sheet -- unlike a filter action.
The downside of this approach is that the parameter values are not loaded dynamically from a data source and that parameters can only have a single value.
Another option could be to use the JavaScript API in some way. You could listen for changes to the selection, and take whatever action you want in response. That only works if you publish to Tableau Server, and you may want to then pull out some of the navigation controls into your own HTML/CSS -- say to filter the second dashboard just before switching to it.
In Codeigniter, I have a table, and I am trying to apply multiple filters on it at the same time.
For example, let's say I make 5 checkboxes and a button "apply", each of the checkboxes applies a filter to my table like so:
When I click on first check box, I want my url to change from localhost/ci to localhost/ci/filter1.
When I click both checkbox1 and checkbox2, I want my url to change to localhost/ci/filter1/filter2 and so on.
Is there any way to do this without using jQuery, or AJAX?
I have a bit of a unique challenge today. I have a client that wants to be able to search for multiple items based on inserts into a cfgrid. Suppose we have the following web form:
A Country selection dropdown
A State Selection dependent AJAX dropdown
A city Selection dependent AJAX dropdown
An ADD Button
----------------------------------------------------
A CFGRID that will populate a row with selections when the user clicks the add button
----------------------------------------------------
And finally, a CLEAR button, and a GO button on the bottom.
The resulting page will then query the database and get some statistics about the cities selected. So, suppose an individual picks USA > Arizona > Scottsdale and USA > Arizona > Flagstaff. The grid below the options will 'save' each selection and reset to their default options, waiting for a user to pick additional options or click on 'GO'.
The resulting page will then generate columns that list some statistics about the communities and highlight the 'best of' between each selected community.
Each time a user selects the ADD button (assuming three criteria are selected) I want the information to be added into a CFGRID that displays the options selected. Then, After the user selects at least one country/city/state option, have all of the data in the CFGRID get passed to another page that does a query from the data selected. In theory, the user could pick as many communities as they want, assuming they are willing to let the database sludge through enough data to get what they want and wait through a 'loading' screen to get it.
I'm having these challenges, in no particular order:
- I have an HTML grid that I must use per client spec (No Java or Flash, must be HTML)
- I have no idea how to get the selected options into the CFGRID. I assume there is some JavaScript I can write that uses some sort of AddRow function to add data into the grid with the add button but cannot seem to find how to it on the interwebs
- After we conquer the above challenge, how do I pass the data from the grid into the results page? I thought about passing one big string or a structure, but I'm not sure how to do that through the URL or posting, nor how to get the data out of the grid. I wonder if I am better off coding some sort of string that gets passed from the options page to the results page with a get method instead of dealing with the stuff in the CFGRID and have the CFGRID serve only as a 'dummy' display container.
- Finally, after the pass is complete, I would need to loop through through the structure and perform a CFQUERY or CFSTOREDPROC on each row of data, then get the statistics I need to display on the results page. I assume this would depend on how I am getting the data from the options selection page to the results page.
THANK YOU ALL!
CFGRID is great to start, but it can be b*tch to customize and extend... Have you tried editable CFGRID with bind? See how far off it is from what you want first. If it turns out to be very far, then you might want to go for a jqGrid and code up some jQuery.
To start, read Using HTML grids and make the cfgrid editable.

Once you got that working, look at these provided JS functions that you can use with CFGRID

If you still demand a bit more, you might need to dig into the underlying ExtJS component. At that point I would rather use jqGrid
I found out that the best way to handle this was by using a SerializeJSON call and a Deserialize JSON call back and forth. By using JavaScript notation we are able to pass a complex JavaScript object (array) between one page and another. This has the value add of not having to worry about sessions timing out and making URLs clickable from one solution to the next.
