Is there some example js that shows how to populate a text field on a form, based upon what option is chosen in a select form field? The options can be hardcoded and it would be great to also have a default if js is off on the client side.code...
I'm using the following code to remove an option from a select control based on a selection in a different select control and the option text in the select option that is being removed. The code works as I want it to, but I would prefer to use the option value for identifying the option to remove instead of using the option text. I've tried several different ways to do this, but can not find the proper syntax.
I want a page to have a different item pre-selected in an option menu-button according to the parameter at the end of the URL. Eg if the URL ends in "?choice=Beta", the item that says "Beta" should be pre-selected. Here's what I have so far:
My mission: Open/collapse TD cells based on items selected in a list box. Getting no response from jQuery so I've done something wrong but cant quite get there. Listbox 'mainselect' contains option values that refer to names of TDs in a table. When a mainselect option is clicked, it will toggle to open or close the referenced TD list box by option value. Does hide/show make a TD 'blank' or actually set it's width to '0'? I want it to close, moving other cells left.
I have a php function that list all of the countries from my database as a select option, then based on what the user selects for their country im using jquery to make an ajax call and get all of the states/regions for that country. This part works fine. I'm running into an issues, as when a user login's in to edit their profile, how would I make the select change based on what is in the databse.
I've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost.When I select the first option nothing appears in the second option.
var f = document.getElementById("f1"); // f1 is id of a form var i = document.createElement("input"); i.setAttribute("type", "text"); f.appendChild(i);
the page immediately shows the new textbox under that form. But in the following code, this doesnt happen.
<form id="f1"> <select id="cars"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="fiat">Fiat</option> <option value="audi">Audi</option> </select> </form> <script> // Gets executed say on click of some button var c = document.getElementById("cars"); c.options.setAttribute("selected", "selected"); // doesnt work c.options.selected = true; // works </script>
the option in combo box remains same. I checked in Firebug that the attribute is added properly. Using the selected attribute works. Why so?
I am working on a class registration system that requires students to register for a main class (101, 102 or 103). The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data
1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table) 2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103).
How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2.
For Example: If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100. If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200
I'm having some trouble with what seems to be a fairly simple issue: I have a <select> field with a few options inside of it. The idea is that a user can select an option in this dropdown and, dependent on what they choose, the output in another div with change.
The form: <form class="formStyle"> <fieldset> <label for="soFormStyle">style:</label> <select name="soFormStyle" id="soFormStyle">
So, this JQuery only works if the option is preselected (if I select and reload the page). I thought I was on the right track, but I just can't get it working as I intended. Again, the idea is that a user selects "Page Curl" or "Logo", and the image in the preview pane changes according to their selection.
I have a select dropdown with several options. The user selects an option and fills out the following few fields. If the user then changes his mind and changes the option in the dropdown, I want all the fields - or just the ones already filled out - to be cleared.
Note: reset() of the form is not an option as there are other things going on (hide/display of fields based on the dropdown option selected).
I know this will have been covered but search isn't working for me at the moment. Easy one for people who know JS anyway, I'm sure: I have a SELECT box that precedes a text input, however, when a particular option is selected (the value of which is "BETWEEN") I need a hidden SPAN to become visible. It is hidden as default with "visibility:hidden;" so I need to just change it to "visibility:visible;" if memory serves. Anyway, likewise, if it is already visible, I need it to be both hidden and have the input in that span have an empty value. Any tips? I need to apply this to many rows in a table, so a function that I can call with the span and input IDs would be best I reckon.
I want to have several forms on one page that are not displayed until a selection is made from the category drop down box(select element). The form displayed will depend on the selection made. Here is the code I have so far.
I have a form on which two separate drop down values need to change based on which option the user selects at the top of the form ("dbt" refers to the remote database the results are pulled from);I have to stick to the names/ids otherwise the form will return an error.I've found examples that dynamically change ONE select list, but not two.
I'm making a form with some select options, and when clicking an option from the drop down, another option will appear.
